deficit

The CBO report on Trump’s terrible new budget

And now back to our regularly scheduled programming. We’re back to talking about economics, which in our current environment pretty much always means bad news. The budget the House passed is pretty much the same terrible one Trump proposed.

The Congressional Budget Office (CBO), one of those bureaucratic agencies that most people barely even realize exists, but is actually extremely useful, spectacularly competent, and indeed one of the most important and efficient agencies in the world, has released its official report on the Trump budget that recently passed the House. (Other such agencies include the Bureau of Labor Statistics and the Bureau of Economic Analysis. US economic statistics are among the best in the world—some refer to them as the “gold standard”, but I refuse to insult them in that way.)

The whole thing is pretty long, but you can get a lot of the highlights from the summary tables.

The tables are broken down by the House committee responsible for choosing them; here are the effects on the federal budget deficit the CBO predicts for the next 5 and 10 years. For these numbers, positive means more deficit (bad), negative means less deficit (good).

Commitee5 years10 years
Agriculture-88,304-238,238
Armed Services124,602143,992
Education and Workforce-253,295-349,142
Energy and Commerce-247,074-995,062
Financial Services-373-5,155
Homeland Security27,87467,147
Judiciary26,9896,910
Natural Resources-4,789-20,158
Oversight and Government Reform-17,449-50,951
Transportation and Infrastructure-361-36,551
Ways and Means2,199,4033,767,402

These are in units of millions of dollars.

Almost all the revenue comes from the Ways and Means committee, because that’s the committee that sets tax rates. (If you hate your taxes, don’t hate the IRS; hate the Ways and Means Committee.) So for all the other departments, we can basically take the effect on the deficit as how much spending was changing.

If this budget makes it through the Senate, Trump will almost certainly sign it into law. If that happens:

We’ll be cutting $238 billion from Agriculture Committee programs: And most of where those cuts come from are programs that provide food for poor people.

We’ll be adding $144 billion to the military budget, and a further $67 billion to “homeland security” (which here mostly means CBP and ICE). Honestly, I was expecting more, so I’m vaguely relieved.

We’ll be cutting $349 billion from Education and Workforce programs; this is mostly coming from the student loan system, so we can expect much more brutal repayment requirements for people with student loans.

We’ll be cutting almost $1 trillion from Energy and Commerce programs; this is mainly driven by massive cuts to Medicare and Medicaid (why are they handled by this committee? I don’t know).
The bill itself doesn’t clearly specify, so the CBO issued another report offering some scenarios for how these budget cuts could be achieved. Every single scenario results in millions of people losing coverage, and the one that saves the most money would result in 5.5 million people losing some coverage and 2.4 million becoming completely uninsured.

The $20 billion from Natural Resources mostly involves rolling back environmental regulations, cutting renewable energy subsidies, and making it easier to lease federal lands for oil and gas drilling. All of these are bad, and none of them are surprising; but their effect on the budget is pretty small.

The Oversight and Government Reform portion is reducing the budget deficit by $51 billion mainly by forcing federal employees to contribute a larger share of their pensions—which is to say, basically cutting federal salaries across the board. While this has a small effect on the budget, it will impose substantial harm on the federal workforce (which has already been gutted by DOGE).

The Transportation and Infrastructure changes involve expansions of the Coast Guard (why are they not in Armed Services again?) along with across-the-board cuts of anything resembling support for sustainability or renewable energy; but the main way they actually decrease the deficit is by increasing the cost of registering cars. I think they’re trying to look like they are saving money by cutting “wasteful” (read: left-wing) programs, but in fact they mainly just made it more expensive to own a car—which, quite frankly, is probably a good thing from an environmental perspective.

Then, last but certainly not least, we come to the staggering $3.7 trillion increase in our 10-year deficit from the Ways and Means committee. What is this change that is more than 3 times as expensive as all the savings from the other departments combined?

Cutting taxes on rich people.

They are throwing some bones to the rest of the population, such as removing the taxes on tips and overtime (temporarily), and making a bunch of other changes to the tax code in terms of deductions and credits and such (because that’s what we needed, a more complicated tax code!); but the majority of the decrease in revenue comes from cutting income taxes, especially at the very highest brackets.

The University of Pennsylvania estimates that the poorest 40% of the population will actually see their after-tax incomes decrease as a result of the bill. Those in the 40% to 80% percentiles will see very little change. Only those in the richest 20% will see meaningful increases in income, and those will be highest for the top 5% and above.

The 95-99% percentile will see the greatest proportional gain, 3.5% of their income.

But the top 0.1% will see by far the greatest absolute gain, each gaining an average of $385,000 per year. Every one of these people already has an annual income of at least $4 million.

The median price of a house in the United States is $416,000.

That is, we are basically handing a free house to every millionaire in America—every year for the next 10 years.

That is why we’re adding $3.7 trillion to the national debt. So that the top 0.1% can have free houses.

Without these tax cuts, the new budget would actually reduce the deficit—which is really something we ought to be doing, because we’re running a deficit of $1.8 trillion per year and we’re not even in a recession. But because Republicans love nothing more than cutting taxes on the rich—indeed, sometimes it seems it is literally the only thing they care about—we’re going to make the deficit even bigger instead.

I can hope this won’t make it through the Senate, but I’m not holding my breath.

Trump has proposed an even worse budget

May 11 JDN 2460807

I didn’t really intend for my blog this year to be taken over by talk about Trump. But all the damage that Trump is doing to America and the world is clearly the most important thing going on in economics right now, and it’s honestly just hard for me to think about anything else.

Trump has proposed a budget. (Read at your own risk; what’s on the White House website is more screed than budget proposal. And it’s pretty clearly written by Trump himself, perhaps with some editing.)

It will come as no surprise to all of you that it is a terrible budget, even worse than what the Republicans recently passed.

First of all, Trump is cutting discretionary spending by $163 billion. This is a huge cut—it removes almost one-fourth of all non-military discretionary spending. Trump naturally claims that he’s just reducing waste, shutting down DEI programs (for the right wing this is considered a good thing), what Trump calls “Green New Scam funding” (read: anything remotely related to environmental sustainability or climate change), and what Trump claims are “large swaths of the Federal Government weaponized against the American people” (read: any other departments Trump doesn’t like, whether or not he actually understands what they are for).

And lest you think that these draconian cuts are being done for fiscal responsibility in the face of an utterly massive federal deficit, Trump also proposes to increase military spending by 13%; multiplying that by our current $850 billion budget means he’s adding $110 billion to the military; and he also says he wants to add a further $119 billion in the mandatory budget. This means he’s cutting $163 billion from non-military spending and adding $239 billion in military spending—which will actually increase the deficit.

Trump is ending programs like the Cybersecurity and Infrastructure Security Agency (sure, let’s just let Chinese hackers in! Why not? It’s not like there’s anything important on those Pentagon servers!) and Fair Housing (amid a historic housing crisis), as well as slashing the EPA (because who needs clean air and water anyway?).

Unsurprisingly, he’s also ending anything that resembles DEI, which includes both some really good necessary programs, and also some stuff that is genuinely ineffective or even counterproductive. Most people who work at firms that have DEI programs think that the programs do more good than harm, but there are big partisan differences, so cutting DEI will play well with the Republican base. But I for one do not want to play the word game where we say out loud every time “diversity, equity, and inclusion”, because there is a big difference between the fundamentally laudable goals of diversity, equity and inclusion, and the actual quite mixed results from DEI programs as they have been implemented. It’s awful that Trump is cutting DEI with a chainsaw, but we really should have been cutting it with a scalpel for awhile now.

Trump is also throwing money at the border, increasing the budgets of CBP (whatever) and ICE (very, very bad!). This is probably the worst thing about the budget, though it also isn’t a big surprise. Part of the increased ICE spending is “50,000 detention beds”, which since ICE lately has been arresting and detaining people without warrants or trials and courts have specifically ruled that they are violating due process, I believe we can fairly say constitutes a concentration camp. If and when they start actually giving everyone—everyone, dammit—due process, then you can call it a detention center.

Trump is eliminating USAID and folding what’s left of it into DFC; but these institutions had quite different goals. USAID had two goals: Advance America’s interests, and make the world a better place. And while it did have significant flaws, overall it did quite a good job of achieving both of those goals—and indeed, publicly making the world a better place can advance America’s interests. DFC’s goal is to promote economic development by financing investments that otherwise could not be financed. That can also promote America’s interests and make the world a better place, but it excludes many of the vital roles that USAID has played in providing humanitarian aid and disaster relief as well as promoting democracy and advancing environmental sustainability. (And when I say “promoting democracy”, I don’t mean the way the CIA does it, by orchestrating coups; I mean things like helping Ukraine remove its dependency on Russia.) There is more to life than money—but I don’t think Trump really understands that.

Trump is canceling a bunch of subsidies to renewable energy, but honestly I’m not too worried about that; the technology has matured so much that renewable energy is actually the cheapest form of energy for most purposes. (And it kinda makes sense: The sun and wind are already there.) Removing the subsidies will make it harder to compete with oil (because oil is still heavily subsidized); but I still think renewables can win. Basically the past subsidies have done their job, and it’s probably okay to remove them.

There’s a really weird proposal involving food, which I think I will just quote in its entirety:

The Budget also supports the creation of MAHA food boxes, that would be filled with commodities sourced from domestic farmers and given directly to American households.

This sounds… kinda… Maoist? Definitely some kind of communist. Why are we circumventing the highly-functional capitalist market for food with massive in-kind transfers? (Despite scaremongering, groceries in the US are still pretty affordable by world standards.) And how are we going to do that, logistically? (Produce does need to be kept fresh, after all.) Does Trump think that markets have trouble providing food in this country? Does he not understand that SNAP exists, and already prioritizes healthier food?(Or does he plan to get rid of it?) Does he think that the reason most Americans don’t eat a very good diet (which is objectively true) is that they aren’t able to get fresh produce? (And not, say, subsidies for factory-farmed meat and high-fructose corn syrup, or mass marketing campaigns by corporations that make junk food?) I’m not so much against this program as I am really baffled by it. It seems like it’s trying to solve the wrong problem by the wrong means. (I’m guessing RFK Jr. had a hand in this, and I recently learned that he doesn’t believe in germ theory. He is a god-tier crank. Like, his views on vaccines and autism were bad enough, but this? Seriously, you put this guy in charge of public health!?)

There are some things in the budget that aren’t terrible, but they’re mostly pretty small.

One actually good thing about Trump’s new budget is the expansion of VA services. I don’t really have any objection to that. It’s a fairly small portion of the budget, and veterans deserve better than they’ve been getting.

Trump says he won’t be cutting Social Security (so perhaps we dodged a bullet on that one). Of course, if he actually cared in the least about the budget deficit, that’s probably what he would cut, because it’s such a huge proportion of our spending—about one-fifth of all federal spending.

I’m not sure what to think about the changes Trump is making to education funding. He’s shutting down the Department of Education, but it seems like most of what it does (including offering grants and handling student loans) is just going to be folded into other agencies. It doesn’t actually seem like there have been substantial cuts in their services, just… a weird and unnecessary reorganization. My guess is that after Trump had already publicly committed to “end the Department of Education”, some staffer quietly explained to him what the Department of Education actually does and why it is necessary; since he’d already committed to shutting it down, he didn’t want to pivot on that, so instead he shut it down in name only while preserving most of what it actually does in other agencies.

Trump is also investing heavily in charter schools, which… meh. Some charter schools are really good, some are really bad. There isn’t a clear pattern of them being better or worse than public schools. Overall, the preponderance of evidence suggests that the average charter school is worse than the average public school, but there’s a lot of variation in both, so the odds that any particular charter school is better than any particular public school are still quite high. (I recently learned about this measure of effect size, probability of superiority, and it’s now my new favorite measure of effect size. Eat your heart out, Cohen’s d!)

Trump is also diverting funding to apprenticeships; he’s introducing a new “Make America Skilled Again” (ugh) grant that States would be required to spend at least 10% on apprenticeship. I’m pretty okay with this in general. 10% is not a lot, and we totally could use more apprenticeship programs in fields like welding and pipefitting.

Another good thing Trump is doing is increasing funding for NASA; he’s clearly doing it out of a sense of national pride and hatred of China, but hey, at least he’s doing it. We might actually be able to pull off a human Mars mission (several years from now, mind you!) if this higher funding continues.

Trump is also redirecting DEA spending to Mexico, Central America, South America, and China; since most fentanyl in the US is made in Latin America from Chinese ingredients, this actually makes sense. I still don’t think that criminalization is the best solution to drug abuse, but fentanyl is genuinely very dangerous stuff, so we should definitely be doing something to reduce its usage.

Finally, and somewhat anticlimactically, Trump is creating some kind of new federal fire service that’s supposedly going to improve our response to wildfires. Given that we already have FEMA, a significant improvement seems unlikely. But hey, it’s worth a try!

These small good things should not distract us from the massive damage that this budget would cause if implemented.

It was not necessary to shift $160 billion from non-military to military spending in order to increase funding for NASA and the VA. It was not necessary to cut hundreds of programs and eliminate USAID—the agency which did what may literally be the very best things our government has ever done. DEI programs had their flaws, but it was wrong to eliminate all of them, instead of finding out which ones are effective and which ones are not.

And while it’s a tiny portion of the budget, the cuts to the EPA will kill people. Most likely thousands of Americans will die from the increased air and water pollution. It will be hard to pinpoint exactly who: Would that kid with asthma have died anyway if the air were cleaner? Was that fatal infection from polluted water, or something else? But the statistics will tell us that there were thousands of unnecessary deaths. (Unless of course Trump falsifies the statistics—which he very well might, since he routinely calls our world-class economic data “fake” when it makes him look bad.)

The large federal budget deficit will be in no way reduced by this budget; in fact it will be slightly increased. If we were in a recession, I’d be okay with this kind of deficit; it was actually a good thing that we ran a huge deficit in 2020. But we aren’t yet—and when one does inevitably hit (given the tariffs, I think sooner rather than later), we won’t have the slack in our budget to do the necessary Keynesian stimulus.

I don’t see any mention of what’s going to happen to Medicare and Medicaid; given that these two programs together constitute roughly one fourth of the federal budget—and nearly twice the military budget—this is a very conspicuous absence. It’s possible that Trump’s leaving them alone because he knows how popular they are, but this once again reveals the emptiness of Republican deficit hawkishness: If you really wanted to reduce the deficit by cutting spending, you’d do it by cutting the military, Social Security, Medicare, and Medicaid. Those four things together comprise the majority of the federal budget. Yet it seems that Trump’s budget cuts none of them.

Mind you, I don’t actually want to cut Social Security, Medicare, or Medicaid; so I’m relieved that Trump isn’t doing that. I’m pretty okay with cutting the military, but I’ll admit I’m less enthused about that since the start of the Ukraine War (I think some moderate cuts are still in order, but we should still have a very big military budget to protect ourselves and our allies). But these are the only budget cuts that could realistically reduce the deficit.

What I actually want to happen is higher taxes on rich people. That’s how I want the budget to be balanced. And Trump very obviously will not do that. Indeed he’s almost certainly going to cut them, making our deficit even larger.

So we’re building a concentration camp, the Chinese are going to hack the Pentagon, we’re going to buy more tanks we don’t need, we won’t be able to properly respond to the next recession, and thousands of people will die from air and water pollution. But at least we got more NASA funding!

The Republicans passed a terrible budget

On April 10, the US House of Representatives passed a truly terrible budget bill. It passed on an almost entirely partisan vote—214 Democrats against, 216 Republicans for, 2 Republicans against. So I think it’s quite fair to say that the Republicans passed this budget—not a single Democrat voted for it, and only 2 Republicans voted against it.

So what’s so bad about it?

Well, first of all, in order to avoid showing just how much it will balloon the national debt, the new budget operates on different accounting rules than normal, using what’s called “current policy baseline” instead of the standard method of assuming that policies will end after 10 years.

In addition to retaining $3.8 trillion in tax cuts that were supposed to expire, this budget will cut taxes by $1.5 trillion over 10 years, with the vast majority of those cuts going to the top 1%—thus the real increase in the deficit is a staggering $5.3 trillion over 10 years. This is absolutely not what we need, given that unemployment is actually pretty good right now and we still have a deficit of $1.8 trillion per year. (Yes, really.) That kind of deficit is good in response to a severe recession—I was all in favor of it during COVID, and it worked. But when the economy is good, you’re supposed to balance the budget, and they haven’t.

The richest 1% stand to gain about 4% more income from these tax cuts (which adds up to about $240 billion per year), while the combination of tax cuts and spending cuts would most likely reduce the income of 40% of the population.

They aren’t even cutting spending to offset these tax cuts. This budget only includes a paltry $4 billion in spending cuts—less than 0.1% of the budget. (I mean, sure, $4 billion is a lot of money for a person; but for a whole country as rich and large as ours? It’s a rounding error.) And then it includes $521 billion in spending increases, over 100 times as much.

They are talking about making more cuts, but they’ve been cagey as to where, probably because the only plausible ways to save this much money are the military, Medicaid, Medicare, or Social Security. Obviously Republicans will never cut the military, but the other three programs are also enormously popular, even in deep-red states. It would be not only very harmful to millions of people to cut these programs—it would also be harmful to the Republicans’ re-election chances. They could also get some savings by cutting income security programs like SNAP and TANF, which would probably be less unpopular—but it would also cause enormous suffering.

This new budget is estimated to add some $6.9 trillion to the national debt over 10 years—and even more after that, if the policies actually continue.

I am not exactly a “deficit hawk”; I don’t think the budget should always be balanced. But this is not the time to be increasing the deficit. When times are good, we should balance the budget, so that when we have to go into debt during bad times, we can afford to do so.

And bad times are probably on the horizon, since Trump’s tariff policy is already such a disaster. So are we going to borrow even more then? While bond yields are rising? We’re going to end up spending most of our budget on debt payments! And all this injection of money into the system won’t be good for inflation either (and on top of the tariffs!).

The only sensible thing to do right now is raise taxes on the rich. We need that revenue. We can’t just keep going deeper into debt. And the rich are the ones who would be least harmed by raising taxes—indeed, if you focused the hikes on billionaires, they would barely feel anything at all.

But the Republicans don’t care about what’s in the interest of ordinary Americans. They only care about the interests of the rich. And that’s why they passed this budget.

Good news on the climate, for a change

Aug 7 JDN 2459799

In what is surely the biggest political surprise of the decade—if not the century—Joe Manchin suddenly changed his mind and signed onto a budget reconciliation bill that will radically shift US climate policy. He was the last vote needed for the bill to make it through the Senate via reconciliation (as he often is, because he’s pretty much a DINO).

Because the Senate is ridiculous, there are still several layers of procedure the bill must go through before it can actually pass. But since the parliamentarian was appointed by a Democrat and the House had already passed an even stronger climate bill, it looks like at least most of it will make it through. The reconciliation process means we only need a bare majority, so even if all the Republicans vote against it—which they very likely will—it can still get through, with Vice President Harris’s tiebreaking vote. (Because our Senate is 50-50, Harris is on track to cast the most tie-breaking votes of any US Vice President by the end of her term.) Reconciliation also can’t be filibustered.

While it includes a lot of expenditures, particularly tax credits for clean energy and electric cars, the bill includes tax increases and closed loopholes so that it will actually decrease the deficit and likely reduce inflation—which Manchin said was a major reason he was willing to support it. But more importantly, it promises to reduce US carbon emissions by a staggering 40% by 2030.

The US currently produces about 15 tons of CO2 equivalent per person per year, so reducing that by 40% would drop it to only 9 tons per person per year. This would move us from nearly as bad as Saudi Arabia to nearly as good as Norway. It still won’t mean we are doing as well as France or the UK—but at least we’ll no longer be dragging down the rest of the First World.

And this isn’t a pie-in-the-sky promise: Independent forecasts suggest that these policies may really be able to reduce our emissions that much that fast. It’s honestly a little hard for me to believe; but that’s what the experts are saying.

Manchin wants to call it the Inflation Reduction Act, but it probably won’t actually reduce inflation very much. But some economists—even quite center-right ones—think it may actually reduce inflation quite a bit, and we basically all agree that it at least won’t increase inflation very much. Since the effects on inflation are likely to be small, we really don’t have to worry about them: whatever it does to inflation, the important thing is that this bill reduces carbon emissions.

Honestly, it’ll be kind of disgusting if this actually does work—because it’s so easy. This bill will have almost no downside. Its macroeconomic effects will be minor, maybe even positive. There was no reason it needed to be this hard-fought. Even if it didn’t have tax increases to offset it—which it absolutely does—the total cost of this bill over the next ten years would be less than six months of military spending, so cutting military spending by 5% would cover it. We have cured our unbearable headaches by finally realizing we could stop hitting ourselves in the head. (And the Republicans want us to keep hitting ourselves and will do whatever they can to make that happen.)

So, yes, it’s very sad that it took us this long. And even 60% of our current emissions is still too much emissions for a stable climate. But let’s take a moment to celebrate, because this is a genuine victory—and we haven’t had a lot of those in awhile.

An unusual recession, a rapid recovery

PNRJ current events, macroeconomics, market failure, public policy , , , , , , , ,

Jul 11 JDN 2459407

It seems like an egregious understatement to say that the last couple of years have been unusual. The COVID-19 pandemic was historic, comparable in threat—though not in outcome—to the 1918 influenza pandemic.

At this point it looks like we may not be able to fully eradicate COVID. And there are still many places around the world where variants of the virus continue to spread. I personally am a bit worried about the recent surge in the UK; it might add some obstacles (as if I needed any more) to my move to Edinburgh. Yet even in hard-hit places like India and Brazil things are starting to get better. Overall, it seems like the worst is over.

This pandemic disrupted our society in so many ways, great and small, and we are still figuring out what the long-term consequences will be.

But as an economist, one of the things I found most unusual is that this recession fit Real Business Cycle theory.

Real Business Cycle theory (henceforth RBC) posits that recessions are caused by negative technology shocks which result in a sudden drop in labor supply, reducing employment and output. This is generally combined with sophisticated mathematical modeling (DSGE or GTFO), and it typically leads to the conclusion that the recession is optimal and we should do nothing to correct it (which was after all the original motivation of the entire theory—they didn’t like the interventionist policy conclusions of Keynesian models). Alternatively it could suggest that, if we can, we should try to intervene to produce a positive technology shock (but nobody’s really sure how to do that).

For a typical recession, this is utter nonsense. It is obvious to anyone who cares to look that major recessions like the Great Depression and the Great Recession were caused by a lack of labor demand, not supply. There is no apparent technology shock to cause either recession. Instead, they seem to be preciptiated by a financial crisis, which then causes a crisis of liquidity which leads to a downward spiral of layoffs reducing spending and causing more layoffs. Millions of people lose their jobs and become desperate to find new ones, with hundreds of people applying to each opening. RBC predicts a shortage of labor where there is instead a glut. RBC predicts that wages should go up in recessions—but they almost always go down.

But for the COVID-19 recession, RBC actually had some truth to it. We had something very much like a negative technology shock—namely the pandemic. COVID-19 greatly increased the cost of working and the cost of shopping. This led to a reduction in labor demand as usual, but also a reduction in labor supply for once. And while we did go through a phase in which hundreds of people applied to each new opening, we then followed it up with a labor shortage and rising wages. A fall in labor supply should create inflation, and we now have the highest inflation we’ve had in decades—but there’s good reason to think it’s just a transitory spike that will soon settle back to normal.

The recovery from this recession was also much more rapid: Once vaccines started rolling out, the economy began to recover almost immediately. We recovered most of the employment losses in just the first six months, and we’re on track to recover completely in half the time it took after the Great Recession.

This makes it the exception that proves the rule: Now that you’ve seen a recession that actually resembles RBC, you can see just how radically different it was from a typical recession.

Moreover, even in this weird recession the usual policy conclusions from RBC are off-base. It would have been disastrous to withhold the economic relief payments—which I’m happy to say even most Republicans realized. The one thing that RBC got right as far as policy is that a positive technology shock was our salvation—vaccines.

Indeed, while the cause of this recession was very strange and not what Keynesian models were designed to handle, our government largely followed Keynesian policy advice—and it worked. We ran massive government deficits—over $3 trillion in 2020—and the result was rapid recovery in consumer spending and then employment. I honestly wouldn’t have thought our government had the political will to run a deficit like that, even when the economic models told them they should; but I’m very glad to be wrong. We ran the huge deficit just as the models said we should—and it worked. I wonder how the 2010s might have gone differently had we done the same after 2008.

Perhaps we’ve learned from some of our mistakes.

How about we listen to the Nobel Laureate when we set our taxes?

I know I’m going out on a limb here, but I think it would generally be a good thing if we based our tax system on the advice of Nobel Laureate economists. Joseph Stiglitz wrote a tax policy paper for the Roosevelt Institution last year that describes in detail how our tax system could be reformed to simultaneously restore economic growth, reduce income inequality, promote environmental sustainability, and in the long run even balance the budget. What’s more, he did the math (I suppose Nobel Laureate economists are known for that), and it looks like his plan would actually work.

The plan is good enough that I think it’s worth going through in some detail.

He opens by reminding us that our “debt crisis” is of our own making, the result of politicians (and voters) who don’t understand economics:

“But we should be clear that these crises – which have resulted in a government shutdown and a near default on the national debt – are not economic but political. The U.S. is not like Greece, unable to borrow to fund its debt and deficit. Indeed, the U.S. has been borrowing at negative real interest rates.”

Stiglitz pulls no punches against bad policies, and isn’t afraid to single out conservatives:

“We also show that some of the so-called reforms that conservatives propose would be counterproductive – they could simultaneously reduce growth and economic welfare and increase unemployment and inequality. It would be better to have no reform than these reforms.”

A lot of the news media keep trying to paint Bernie Sanders as a far-left radical candidate (like this article in Politico calling his hometown the “People’s Republic of Burlington”), because he says things like this: “in recent years, over 99 percent of all new income generated in the economy has gone to the top 1 percent.”

But the following statement was not said by Bernie Sanders, it was said by Joseph Stiglitz, who I will remind you one last time is a world-renowned Nobel Laureate economist:

“The weaknesses in the labor market are reflected in low wages and stagnating incomes. That helps explain why 95 percent of the increase in incomes in the three years after the recovery officially began went to the upper 1 percent. For most Americans, there has been no recovery.”

It was also Stiglitz who said this:

“The American Dream is, in reality, a myth. The U.S. has some of the worst inequality across generations (social mobility) among wealthy nations. The life prospects of a young American are more dependent on the income and education of his parents than in other advanced countries.”

In this country, we have reached the point where policies supported by the analysis of world-renowned economists is considered far-left radicalism, while the “mainstream conservative” view is a system of tax policy that is based on pure fantasy, which has been called “puppies and rainbows” by serious policy analysts and “voodoo economics” by yet another Nobel Laureate economist. A lot of very smart people don’t understand what’s happening in our political system, and want “both sides” to be “equally wrong”, but that is simply not the case: Basic facts of not just social science (e.g. Keynesian monetary policy), but indeed natural science (evolutionary biology, anthropogenic climate change) are now considered “political controversies” because the right wing doesn’t want to believe them.

But let’s get back to the actual tax plan Stiglitz is proposing. He is in favor of raising some taxes and lowering others, spending more on some things and less on other things. His basic strategy is actually quite simple: Raise taxes with low multipliers and cut taxes with high multipliers. Raise spending with high multipliers and cut spending with low multipliers.

“While in general taxes take money out of the system, and therefore have a deflationary bias, some taxes have a larger multiplier than others, i.e. lead to a greater reduction in aggregate demand per dollar of revenue raised. Taxes on the rich and superrich, who save a large fraction of their income, have the least adverse effect on aggregate demand. Taxes on lower income individuals have the most adverse effect on aggregate demand.”

In other words, by making the tax system more progressive, we can directly stimulate economic growth while still increasing the amount of tax revenue we raise. And of course we have plenty of other moral and economic reasons to prefer progressive taxation.

Stiglitz tears apart the “job creator” myth:

“It is important to dispel a misunderstanding that one often hears from advocates of lower taxes for the rich and corporations, which contends that the rich are the job producers, and anything that reduces their income will reduce their ability and incentive to create jobs. First, at the current time, it is not lack of funds that is holding back investment. It is not even a weak and dysfunctional financial sector. America’s large corporations are sitting on more than $2 trillion in cash. What is holding back investment, especially by large corporations, is the lack of demand for their products.”

Stiglitz talks about two principles of taxation to follow:

First is the Generalized Henry George Principle, that we should focus taxes on things that are inelastic, meaning their supply isn’t likely to change much with the introduction of a tax. Henry George favored taxing land, which is quite inelastic indeed. The reason we do this is to reduce the economic distortions created by a tax; the goal is to collect revenue without changing the number of real products that are bought and sold. We need to raise revenue and we want to redistribute income, but we want to do it without creating unnecessary inefficiencies in the rest of the economy.

Second is the Generalized Polluter Pays Principle, that we should tax things that have negative externalities—effects on other people that are harmful. When a transaction causes harm to others who were not party to the transaction, we should tax that transaction in an amount equal to the harm that it would cause, and then use that revenue to offset the damage. In effect, if you hurt someone else, you should have to pay to clean up your own mess. This makes obvious moral sense, but it also makes good economic sense; taxing externalities can improve economic efficiency and actually make everyone better off. The obvious example is again pollution (the original Polluter Pays Principle), but there are plenty of other examples as well.

Stiglitz of course supports taxes on pollution and carbon emissions, which really should be a no-brainer. They aren’t just good for the environment, they would directly increase economic efficiency. The only reason we don’t have comprehensive pollution taxes (or something similar like cap-and-trade) is again the political pressure of right-wing interests.

Stiglitz focuses in particular on the externalities of the financial system, the boom-and-bust cycle of bubble, crisis, crash that has characterized so much of our banking system for generations. With a few exceptions, almost every major economic crisis has been preceded by some sort of breakdown of the financial system (and typically widespread fraud by the way). It is not much exaggeration to say that without Wall Street there would be no depressions. Externalities don’t get a whole lot bigger than that.

Stiglitz proposes a system of financial transaction taxes that are designed to create incentives against the most predatory practices in finance, especially the high-frequency trading in which computer algorithms steal money from the rest of the economy thousands of times per second. Even a 0.01% tax on each financial transaction would probably be enough to eliminate this particular activity.

He also suggests the implementation of “bonus taxes” which disincentivize paying bonuses, which could basically be as simple as removing the deductions placed during the Clinton administration (in a few years are we going to have to say “the first Clinton administration”?) that exempt “performance-based pay” from most forms of income tax. All pay is performance-based, or supposed to be. There should be no special exemption for bonuses and stock options.

Stiglitz also proposes a “bank rescue fund” which would be something like an expansion of the FDIC insurance that banks are already required to have, but designed as catastrophe insurance for the whole macroeconomy. Instead of needing bailed out from general government funds, banks would only be bailed out from a pool of insurance funds they paid in themselves. This could work, but honestly I think I’d rather reduce the moral hazard even more by saying that we will never again bail out banks directly, but instead bail out consumers and real businesses. This would probably save banks anyway (most people don’t default on debts if they can afford to pay them), and if it doesn’t, I don’t see why we should care. The only reason banks exist is to support the real economy; if we can support the real economy without them, they deserve to die. That basic fact seems to have been lost somewhere along the way, and we keep talking about how to save or stabilize the financial system as if it were valuable unto itself.

Stiglitz also proposes much stricter regulations on credit cards, which would require them to charge much lower transaction fees and also pay a portion of their transaction revenue in taxes. I think it’s fair to ask whether we need credit cards at all, or if there’s some alternative banking system that would allow people to make consumer purchases without paying 20% annual interest. (It seems like there ought to be, doesn’t it?)

Next Stiglitz gets to his proposal to reform the corporate income tax. Like many of us, he is sick of corporations like Apple and GE with ten and eleven-figure profits paying little or no taxes by exploiting a variety of loopholes. He points out some of the more egregious ones, like the “step up of basis at death” which allows inherited capital to avoid taxation (personally, I think both morally and economically the optimal inheritance tax rate is 100%!), as well as the various loopholes on offshore accounting which allow corporations to design and sell their products in the US, even manufacture them here, and pay taxes as if all their work were done in the Cayman Islands. He also points out that the argument that corporate taxes disincentivize investment is ridiculous, because most investment is financed by corporate bonds which are tax-deductible.

Stiglitz departs from most other economists in that he actually proposes raising the corporate tax rate itself. Most economists favor cutting the rate on paper, then closing the loopholes to ensure that the new rate is actually paid. Stiglitz says this is not enough, and we must both close the loopholes and increase the rate.

I’m actually not sure I agree with him on this; the incidence of corporate taxes is not very well-understood, and I think there’s a legitimate worry that taxing Apple will make iPhones more expensive without actually taking any money from Tim Cook. I think it would be better to get rid of the corporate tax entirely and then dramatically raise the marginal rates on personal income, including not only labor income but also all forms of capital income. Instead of taxing Apple hoping it will pass through to Tim Cook, I say we just tax Tim Cook. Directly tax his $4 million salary and $70 million in stock options.

Stiglitz does have an interesting proposal to introduce “rent-seeking” taxes that specifically apply to corporations which exercise monopoly or oligopoly power. If you can actually get this to work, it’s very clever; you could actually create a market incentive for corporations to support their own competition—and not in the sense of collusion but in the sense of actually trying to seek out more competitive markets in order to avoid the monopoly tax. Unfortunately, Stiglitz is a little vague on how we’d actually pull that off.

One thing I do agree with Stiglitz on is the use of refundable tax credits to support real investment. Instead of this weird business about not taxing dividends and capital gains in the hope that maybe somehow this will support real investment, we actually give tax credits specifically to companies that build factories or hire more workers.

Stiglitz also does a good job of elucidating the concept of “corporate welfare”, officially called “tax expenditures”, in which subsidies for corporations are basically hidden in the tax code as rebates or deductions. This is actually what Obama was talking about when he said “spending in the tax code”, (he did not invent the concept of tax expenditures), but since he didn’t explain himself well even Jon Stewart accused him of Orwellian Newspeak. Economically a refundable tax rebate of $10,000 is exactly the same thing as a subsidy of $10,000. There are some practical and psychological differences, but there are no real economic differences. If you’re still confused about tax expenditures, the Center for American Progress has a good policy memo on the subject.

Stiglitz also has some changes to make to the personal income tax, all of which I think are spot-on. First we increase the marginal rates, particularly at the very top. Next we equalize rates on all forms of income, including capital income. Next, we remove most, if not all, of the deductions that allow people to avoid paying the rate it says on paper. Finally, we dramatically simplify the tax code so that the majority of people can file a simplified return which basically just says, “This is my income. This is the tax rate for that income. This is what I owe.” You wouldn’t have to worry about itemizing your student loans or mortgage payments or whatever else; just tally up your income and look up your rate. As he points out, this would save a lot of people a lot of stress and also remove a lot of economic distortions.

He talks about how we can phase out the mortgage-interest deduction in particular, because it’s clearly inefficient and regressive but it’s politically popular and dropping it suddenly could lead to another crisis in housing prices.

Stiglitz has a deorbit for anyone who thinks capital income should not be taxed:

“There is, moreover, no justification for taxing those who work hard to earn a living at a higher rate than those who derive their income from speculation.”

By equalizing rates on labor and capital income, he estimates we could raise an additional $130 billion per year—just shy of what it would take to end world hunger. (Actually some estimates say it would be more than enough, others that it would be about half what we need. It’s definitely in the ballpark, however.)

Stiglitz actually proposes making a full deduction of gross household income at $100,000, meaning that the vast majority of Americans would pay no income tax at all. This is where he begins to lose me, because it necessarily means we aren’t going to raise enough revenue by income taxes alone.

He proposes to make up the shortfall by introducing a value-added tax, a VAT. I have to admit a lot of countries have these (including most of Europe) and seem to do all right with them; but I never understood why they are so popular among economists. They are basically sales taxes, and it’s very hard to make any kind of sales tax meaningfully progressive. In fact, they are typically regressive, because rich people spend a smaller proportion of their income than poor people do. Unless we specifically want to disincentivize buying things (and a depression is not the time to do that!), I don’t see why we would want to switch to a sales tax.

At the end of the paper Stiglitz talks about the vital difference between short-term spending cuts and long-term fiscal sustainability:

“Thus, policies that promote output and employment today also contribute to future growth – particularly if they lead to more investment. Thus, austerity measures that take the form of cutbacks in spending on infrastructure, technology, or education not only weaken the economy today, but weaken it in the future, both directly (through the obvious impacts, for example, on the capital stock) but also indirectly, through the diminution in human capital that arises out of employment or educational experience. […] Mindless “deficit fetishism” is likely to be counterproductive. It will weaken the economy and prove counterproductive to raising revenues because the main reason that we are in our current fiscal position is the weak economy.”

It amazes me how many people fail to grasp this. No one would say that paying for college is fiscally irresponsible, because we know that all that student debt will be repaid by your increased productivity and income later on; yet somehow people still think that government subsidies for education are fiscally irresponsible. No one would say that it is a waste of money for a research lab to buy new equipment in order to have a better chance at making new discoveries, yet somehow people still think it is a waste of money for the government to fund research. The most legitimate form of this argument is “crowding-out”, the notion that the increased government spending will be matched by an equal or greater decrease in private spending; but the evidence shows that many public goods—like education, research, and infrastructure—are currently underfunded, and if there is any crowding-out, it is much smaller than the gain produced by the government investment. Crowding-out is theoretically possible but empirically rare.

Above all, now is not the time to fret about deficits. Now is the time to fret about unemployment. We need to get more people working; we need to create jobs for those who are already seeking them, better jobs for those who have them but want more, and opportunities for people who have given up searching for work to keep trying. To do that, we need spending, and we will probably need deficits. That’s all right; once the economy is restored to full capacity then we can adjust our spending to balance the budget (or we may not even need to, if we devise taxes correctly).

Of course, I fear that most of these policies will fall upon deaf ears; but Stiglitz calls us to action:

“We can reform our tax system in ways that will strengthen the economy today, address current economic and social problems, and strengthen our economy for the future. The economic agenda is clear. The question is, will the vested interests which have played such a large role in creating the current distorted system continue to prevail? Do we have the political will to create a tax system that is fair and serves the interests of all Americans?”

Fear not the deficit

The deficit! It’s big and scary! And our national debt is rising by the second, says a “debt clock” that is literally just linearly extrapolating the trend. You don’t actually think that there are economists marking down every single dollar the government spends and uploading it immediately, do you? We’ve got better things to do. Conservatives will froth at the mouth over how Obama is the “biggest government spender in world history“, which is true if you just look at the dollar amounts, but of course it is; Obama is the president of the richest country in world history. If the government continues to tax at the same rate and spend what it taxes, government spending will be a constant proportion of GDP (which isn’t quite true, but it’s pretty close; there are ups and downs but for the last 40 years or so federal spending is generally in the range 30% to 35% of GDP), and the GDP of the United States is huge, and far beyond that of any other nation not only today, but ever. This is particularly true if you use nominal dollars, but it’s even true if you use inflation-adjusted real GDP. No other nation even gets close to US GDP, which is about to reach $17 trillion a year (unless you count the whole European Union as a nation, in which case it’s a dead heat).

China recently passed us if you use purchasing-power-parity, but that really doesn’t mean much, because purchasing-power-parity, or PPP, is a measure of standard of living, not a measure of a nation’s total economic power. If you want to know how well people in a country live, you use GDP per capita (that is, per person) PPP. But if you want to know a country’s capacity to influence the world economy, what matters is so-called real GDP, which is adjusted for inflation and international exchange rates. The difference is that PPP will tell you how many apples a person can buy, but real GDP will tell you how many aircraft carriers a government can build. The US is still doing quite well in that department, thank you; we have 10 of the world’s 20 active aircraft carriers, which is to say as many as everyone else combined. The US has 4% of the world’s population and 24% of the world’s economic output.

In particular, GDP in the US has been growing rather steadily since the Great Recession, and we are now almost recovered from the Second Depression and back to our equilibrium level of unemployment and economic growth. As the economy grows, government spending grows alongside it. Obama has actually presided over a decrease in the proportion of government spending relative to GDP, largely because of all this political pressure to reduce the deficit and stop the growth of the national debt. Under Obama the deficit has dropped dramatically.

But what is the deficit, anyway? And how can the deficit be decreasing if the debt clock keeps ticking up?

The government deficit is simply the difference between total government spending and total government revenue. If the government spends $3.90 trillion and takes in $3.30 trillion, the deficit is going to be $0.60 trillion, or $600 billion. In the rare case that you take in more than you spend, the deficit would be negative; we call that a surplus instead. (This almost never happens.)

Because of the way the US government is financed, the deficit corresponds directly to the national debt, which is the sum of all outstanding loans to the government. Every time the government spends more than it takes in, it makes up the difference by taking out a loan, in the form of a Treasury bond. As long as the deficit is larger than zero, the debt will increase. Think of the debt as where you are, and the deficit as how fast you’re going; you can be slowing down, but you’ll continue to move forward as long as you have some forward momentum.

Who is giving us these loans? You can look at the distribution of bondholders here. About a third of the debt is owned by the federal government itself, which makes it a very bizarre notion of “debt” indeed. Of the rest, 21% is owned by states or the Federal Reserve, so that’s also a pretty weird kind of debt. Only 55% of the total debt is owned by the public, and of those 39% are people and corporations within the United States. That means that only 33% of the national debt is actually owned by foreign people, corporations, or governments. What we actually owe to China is about $1.4 trillion. That’s a lot of money (it’s literally enough to make an endowment that would end world hunger forever), but our total debt is almost $18 trillion, so that’s only 8%.

When most people see these huge figures they panic: “Oh my god, we owe $18 trillion! How will we ever repay that!” Well, first of all, our GDP is $17 trillion, so we only owe a little over one year of income. (I wish I only owed one year of income in student loans….)

But in fact we don’t really owe it at all, and we don’t need to ever repay it. Chop off everything that’s owned by US government institutions (including the Federal Reserve, which is only “quasi-governmental”), and the figure drops down to $9.9 trillion. If by we you mean American individuals and corporations, then obviously we don’t owe back the debt that’s owned by ourselves, so take that off; now you’re looking at $6 trillion. That’s only about 4 months of total US economic output, or less than two years of government revenue.

And it gets better! The government doesn’t need to somehow come up with that money; they don’t even have to raise it in taxes. They can print that money, because the US government has a sovereign currency and the authority to print as much as we want. Really, we have the sovereign currency, because the US dollar is the international reserve currency, the currency that other nations hold in order to make exchanges in foreign markets. Other countries buy our money because it’s a better store of value than their own. Much better, in fact; the US has the most stable inflation rate in the world, and has literally never undergone hyperinflation. Better yet, the last time we had prolonged deflation was the Great Depression. This system is self-perpetuating, because being the international reserve currency also stabilizes the value of your money.

This is why it’s so aggravating to me when people say things like “the government can’t afford that” or “the government is broke” or “that money needs to come from somewhere”. No, the government can’t be broke! No, the money doesn’t have to come from somewhere! The US government is the somewhere from which the world’s money comes. If there is one institution in the world that can never, ever be broke, it is the US government. This gives our government an incredible amount of power—combine that with our aforementioned enormous GDP and fleet of aircraft carriers, and you begin to see why the US is considered a global hegemon.

To be clear: I’m not suggesting we eliminate all taxes and just start printing money to pay for everything. Taxes are useful, and we should continue to have them—ideally we would make them more progressive than they presently are. But it’s important to understand why taxes are useful; it’s really not that they are “paying for” government services. It’s actually more that they are controlling the money supply. The government creates money by spending, then removes money by taxing; in this way we maintain a stable growth of the money supply that allows us to keep the economy running smoothly and maintain inflation at a comfortable level. Taxes also allow the government to redistribute income from those who have it and save it to those who need it and will spend it—which is all the more reason for them to be progressive. But in theory we could eliminate all taxes without eliminating government services; it’s just that this would cause a surge in inflation. It’s a bad idea, but by no means impossible.

When we have a deficit, the national debt increases. This is not a bad thing. This is a fundamental misconception that I hope to disabuse you of: Government debt is not like household debt or corporate debt. When people say things like “we need to stop spending outside our means” or “we shouldn’t put wars on the credit card”, they are displaying a fundamental misunderstanding of what government debt is. The government simply does not operate under the same kind of credit constraints as you and I.

First, the government controls its own interest rates, and they are always very low—typically the lowest in the entire economy. That already gives it a lot more power over its debt than you or I have over our own.

Second, the government has no reason to default, because they can always print more money. That’s probably why bondholders tolerate the fact that the government sets its own interest rates; sure, it only pays 0.5%, but it definitely pays that 0.5%.

Third, government debt plays a role in the functioning of global markets; one of the reasons why China is buying up so much of our debt is so that they can keep the dollar high in value and thus maintain their trade surplus. (This is why whenever someone says something like, “The government needs to stop going further into debt, just like how I tightened my belt and paid off my mortgage!” I generally reply, “So when was the last time someone bought your debt in order to prop up your currency?”) This is also why we can’t get rid of our trade deficit and maintain a “strong dollar” at the same time; anyone who wants to do that may feel patriotic, but they are literally talking nonsense. The stronger the dollar, the higher the trade deficit.

Fourth, as I already hinted at above, the government doesn’t actually need debt at all. Government debt, like taxation, is not actually a source of funding; it is a tool of monetary policy. (If you’re going to quote one sentence from this post, it should be the previous; that basically sums up what I’m saying.) Even without raising taxes or cutting spending, the government could choose not to issue bonds, and instead print cash. You could make a sophisticated economic argument for how this is really somehow “issuing debt with indefinite maturity at 0% interest”; okay, fine. But it’s not what most people think of when they think of debt. (In fact, sophisticated economic arguments can go quite the opposite way: there’s a professor at Harvard I may end up working with—if I get into Harvard for my PhD of course—who argues that the federal debt and deficit are literally meaningless because they can be set arbitrarily by policy. I think he goes too far, but I see his point.) This is why many economists were suggesting that in order to get around ridiculous debt-ceiling intransigence Obama could simply Mint the Coin.

Government bonds aren’t really for the benefit of the government, they’re for the benefit of society. They allow the government to ensure that there is always a perfectly safe investment that people can buy into which will anchor interest rates for the rest of the economy. If we ever did actually pay off all the Treasury bonds, the consequences could be disastrous.

Fifth, the government does not have a credit limit; they can always issue more debt (unless Congress is filled with idiots who won’t raise the debt ceiling!). The US government is the closest example in the world to what neoclassical economists call a perfect credit market. A perfect credit market is like an ideal rational agent; these sort of things only exist in an imaginary world of infinite identical psychopaths. A perfect credit market would have perfect information, zero transaction cost, zero default risk, and an unlimited quantity of debt; with no effort at all you could take out as much debt as you want and everyone would know that you are always guaranteed to pay it back. This is in most cases an utterly absurd notion—but in the case of the US government it’s actually pretty close.

Okay, now that I’ve deluged you with reasons why the national debt is fundamentally different from a household mortgage or corporate bond, let’s get back to talking about the deficit. As I mentioned earlier, the deficit is almost always positive; the government is almost always spending more money than it takes in. Most people think that is a bad thing; it is not.

It would be bad for a corporation to always run a deficit, because then it would never make a profit. But the government is not a for-profit corporation. It would be bad for an individual to always run a deficit, because eventually they would go bankrupt. But the government is not an individual.

In fact, the government running a deficit is necessary for both corporations to make profits and individuals to gain net wealth! The government is the reason why our monetary system is nonzero-sum.

This is actually so easy to see that most people who learn about it react with shock, assuming that it can’t be right. There can’t be some simple and uncontroversial equation that shows that government deficits are necessary for profits and savings. Actually, there is; and the fact that we don’t talk about this more should tell you something about the level of sophistication in our economic discourse.

Individuals do work, get paid wages W. (This also includes salaries and bonuses; it’s all forms of labor income.) They also get paid by government spending, G, and pay taxes, T. Let’s pretend that all taxing and spending goes to people and not corporations. This is pretty close to true, especially since corporations as big as Boeing frequently pay nothing in taxes. Corporate subsidies, while ridiculous, are also a small portion of spending—no credible estimate is above $300 billion a year, or less than 10% of the budget. (Without that assumption the equation has a couple more terms, but the basic argument doesn’t change.) People use their money to buy consumption goods, C. What they don’t spend they save, S.

S = (W + G – T) – C

I’m going to rearrange this for reasons that will soon become clear:

S = (W – C) + (G – T)

I’ll also subtract investment I from both sides, again for reasons that will become clear:

S – I = (W – C – I) + (G – T)

Corporations hire workers and pay them W. They make consumption goods which are then sold for C. They also sell to foreign companies and buy from foreign companies, exporting X and importing M. Since we have a trade deficit, this means that X < M. Finally, they receive investment I that comes in the form of banks creating money through loans (yes, banks can create money). Most of our monetary policy is in the form of trying to get banks to create more money by changing interest rates. Only when desperate do we actually create the money directly (I’m not sure why we do it this way). In any case, this yields a total net profit P.

P = C + I – W + (X – M)

Now, if the economy is functioning well, we want profits and savings to both be positive—both people and corporations will have more money on average next year then they had this year. This means that S > 0 and P > 0. We also don’t want the banks loaning out more money than people save—otherwise people go ever further into debt—so we actually want S > I, or S – I > 0. If S – I > 0, people are paying down their debts and gaining net wealth. If S – I < 0, people are going further into debt and losing net wealth. In a well-functioning economy we want people to be gaining net wealth.

In order to have P > 0, because X – M < 0 we need to have C + I > W. People have to spend more on consumption and investment than they are paid in wages—have to, absolutely have to, as a mathematical law—in order for corporations to make a profit.

But then if C + I > W, W – C – I < 0, which means that the first term of the savings equation is negative. In order for savings to be positive, it must be—again as a mathematical law—that G – T > 0, which means that government spending exceeds taxes. In order for both corporations to profit and individuals to save at the same time, the government must run a deficit.

There is one other way, actually, and that’s for X – M to be positive, meaning you run a trade surplus. But right now we don’t, and moreover, the world as a whole necessarily cannot. For the world as a whole, X = M. This will remain true at least until we colonize other planets. This means that in order for both corporate profits and individual savings to be positive worldwide, overall governments worldwide must spend more than they take in. It has to be that way, otherwise the equations simply don’t balance.

You can also look at it another way by adding the equations for S – I and P:

S – I + P = (G – T) + (X – M)

Finally, you can also derive this a third way. This is your total GDP which we usually call Y (“yield”, I think?); it’s equal to consumption plus investment plus government spending, plus net exports:

Y = C + I + G + (X – M)

It’s also equal to consumption plus profit plus saving plus taxes:

Y = C + P + S + T

So those two things must be the same:

C + S + T + P = C + I + G + (X – M)

Canceling and rearranging we get:

(S – I) + P = (G – T) + (X – M)

The sum of saving minus investment (which we can sort of think of as “net saving”) plus profit is equal to the sum of the government deficit and the trade surplus. (Usually you don’t see P in this sectoral balances equation because no distinction is made between consumers and corporations and P is absorbed into S.)

From the profit equation:

W = C + I + (X – M) – P

Put that back into our GDP equation:

Y = W + P + G

GDP is wages plus profits plus government spending.

That’s a lot of equations; simple equations, but yes, equations. Lots of people are scared by equations. So here, let me try to boil it down to a verbal argument. When people save and corporations make profits, money gets taken out of circulation. If no new money is added, the money supply will decrease as a result; this shrinks the economy (mathematically it must absolutely shrink it in nominal terms; theoretically it could cause deflation and not reduce real output, but in practice real output always goes down because deflation causes its own set of problems). New money can be created by banks, but the mechanism of creation requires that people go further into debt. This is unstable, and eventually people can’t borrow anymore and the whole financial system comes crashing down. The better way, then, is for the government to create new money. Yes, as we currently do things, this means the government will go further into debt; but that’s all right, because the government can continue to increase its debt indefinitely without having to worry about hitting a ceiling and making everything fall apart. We could also just print money instead, and in fact I think in many cases this is what we should do—but for whatever reason people always freak out when you suggest such a thing, invariably mentioning Zimbabwe. (And yes, Zimbabwe is in awful shape; but they didn’t just print money to cover a reasonable amount of deficit spending. They printed money to line their own pockets, and it was thousands of times more than what I’m suggesting. Also Zimbabwe has a much smaller economy; $1 trillion is 5% of US GDP, but it’s 8,000% of Zimbabwe’s. I’m suggesting we print maybe 4% of GDP; at the peak of the hyperinflation they printed something more like 100,000%.)

One last thing before I go. If investment suddenly drops, net saving will go up. If the government deficit and trade deficit remain constant, profits must go down. This drives firms into bankruptcy, driving wages down as well. This makes GDP fall—and you get a recession. A similar effect would occur if consumption suddenly drops. In both cases people will be trying to increase their net wealth, but in fact they won’t be able to—this is what’s called the paradox of thrift. You actually want to increase the government deficit under these circumstances, because then you will both add to GDP directly and allow profits and wages to go back up and raise GDP even further. Because GDP has gone down, tax income will go down, so if you insist on balancing the budget, you’ll cut spending and only make things worse.

Raising the government deficit generally increases economic growth. From these simple equations it looks like you could raise GDP indefinitely, but these are nominal figures—actual dollar amounts—so after a certain point all you’d be doing is creating inflation. Where exactly that point is depends on how your economy is performing relative to its potential capacity. In a recession you are far below capacity, so that’s just the time to spend. You’d only want a budget surplus if you actually thought you were above long-run capacity, because you’re depleting natural resources or causing too much inflation or something like that. And indeed, we hardly ever see budget surpluses.

So that, my dear reader, is why we don’t need to fear the deficit. Government debt is nothing like other forms of debt; profits and savings depend upon the government spending more than it takes in; deficits are highly beneficial during recessions; and the US government is actually in a unique position to never worry about defaulting on its debt.
