A “Normal” Budget Isn’t Really Normal

Treasury closed the financial books on fiscal 2014 last week. As my colleague Howard Gleckman noted, the top line figures all came in close to their 40-year averages. The $483 billion deficit was about 2.8 percent of gross domestic product, for example, slightly below the 3.2 percent average of the past four decades. Tax revenues clocked in at 17.5 percent of GDP, a smidgen above their 17.3 percent 40-year average. And spending was 20.3 percent, a bit below its 20.5 percent average.

Taxes, spending, and deficits thus appear to be back to “normal.” If anything, fiscal policy in 2014 was slightly tighter than the average of the past four decades.

That’s all true, as a matter of arithmetic. But should we use the past 40 years as a benchmark for normal budget policy?

It’s common to do so. The Congressional Budget Office often reports 40-year averages to help put budget figures in context. I’ve invoked 40-year averages as much as anyone.

But what has been the result of that “normal” policy? From 1975 to today, the federal debt swelled from less than 25 percent of GDP to more than 70 percent. I don’t think many people would view that as normal. Or maybe it is normal, but not in a good way.

Just before the Great Recession, the federal debt was only 35 percent of GDP. Over the previous four decades (1968 through 2007), the deficit had averaged 2.3 percent of GDP, almost a percentage point lower than today’s 40-year average.

That comparison illustrates the problem with mechanically using 40-year averages as a benchmark for normal. A few extreme years can skew the figures. In 2007, we would have said deficits around 2 percent of GDP were normal. Today, the post-Great Recession average tempts us to think of 3 percent as normal. The Great Recession has similarly skewed up average spending (from 19.9 percent to 20.5 percent) and skewed down average taxes (from 17.6 percent to 17.3 percent).

As recent years demonstrate, we don’t want a normal budget every year. When the economy is weak, it makes sense for taxes to fall and spending and deficits to rise. When the economy is strong, deficits should come down, perhaps even disappear, through a mix of higher revenues and lower spending.

Looking over the business cycle, however, it is useful to have some budget benchmarks. A mechanical calculation of 40-year averages won’t serve. Instead, we need more objective benchmarks. On Twitter, Brad Delong suggested one benchmark for deficits: the level that would keep the debt-to-GDP ratio constant. I welcome other suggestions.

The $300 Billion Question: How Should Congress Budget for Federal Lending Programs?

Lending programs create special challenges for federal budgeting. So special, in fact, that the Congressional Budget Office estimates their budget effects two different ways. According to official budget rules, taxpayers will earn more than $200 billion over the next decade from new student loans, mortgage guarantees, and the Export-Import Bank. According to an alternative that CBO favors, taxpayers will lose more than $100 billion.

Those competing estimates pose a $300 billion question: Which budgeting approach is best?

As I document in a new report and policy brief, the answer is neither one. Each approach tells only part of the story. Congress would be better served by a new approach that fairly reflects all the fiscal effects of lending.

Compared with what?

If lending programs perform as CBO expects, they will bring in new money that the government can use to reduce the deficit, increase spending, or cut taxes. In that sense, taxpayers may come out more than $200 billion ahead.

But these programs do not fully compensate taxpayers for their financial risk. If the government took the same risk by making loans and guarantees at fair market rates—perhaps by investing in publicly traded bonds—taxpayers would make much more. Taxpayers are subsidizing the students, homeowners, and companies that borrow through these programs. In that sense, taxpayers come out more than $100 billion behind.

The same issue can arise in personal life. Suppose your aunt asks for a $10,000 loan to start a business. You’ve got exactly that much in a government bond fund earning 2.5 percent, and she offers to pay 5 percent. She’s got a good head for business, so the risk of default is very low; realistically you expect a 4 percent annual return.

The loan sounds like a winner, right? Her 4 percent beats the bond fund’s 2.5 percent, if you can handle the risk. But there’s one other thing: your brother-in-law, equally good at business, would like a similar loan, and he’s willing to pay 6 percent, with an expected net of 5 percent.

Now the loan to your aunt sounds like a loser. Your brother-in-law’s 5 percent beats her 4 percent. You might still prefer to lend to her, but you would come out behind in financial terms.

The competing CBO estimates reflect this dichotomy. One approach compares the financial returns of lending with doing nothing (the $200 billion gain in CBO’s case, 4 percent versus 2.5 percent in yours). The other compares the returns with taking similar risks and being fully compensated (the $100 billion loss in CBO’s case, 4 percent versus 5 percent in yours).

Both comparisons provide useful information. If you want to predict the government’s future fiscal condition, you should compare the financial returns of lending with doing nothing. If you want to measure the subsidies given to borrowers, you should compare returns with the fair market alternative.

When you discuss your aunt’s proposal with your spouse, you would be wise to mention not only the potential financial gain (“4 percent is better than 2.5 percent”) but the subsidy to your aunt (“4 percent is less than the 5 percent your brother would pay”). Only then can you have an open discussion of your family’s financial priorities.

Today’s approaches

The same information is necessary for an open discussion of federal budgeting. But official budget rules, created by the Federal Credit Reform Act of 1990 (FCRA), require CBO to use just the first approach in its budget analyses. Official estimates thus measure the fiscal effects of lending, not the subsidies provided to borrowers. CBO rightly believes, however, that policy deliberations are incomplete without measuring the subsidies, which CBO calculates separately using an approach known as fair value.

Policy analysts have vigorously debated the pros and cons of FCRA and fair value for years. Neither side has scored a decisive win for a simple reason: both approaches are incomplete. Fair value measures subsidies well, but tells us nothing about fiscal effects; this is its missing-money problem. FCRA measures lifetime fiscal effects well, but tells us nothing about subsidies.

By recording expected fiscal gains the moment a loan is made, moreover, FCRA makes lending appear to be a magic money machine. Lending may pay off over time, but the gains do not happen the moment the loan’s ink is dry. Like any lender, the government must be patient to earn those returns. It must hold the loan, perhaps for many years, and bear the associated financial risk.

A better approach

For those reasons, I believe we should replace both approaches with a more accurate budgeting method, which I call expected returns. As the report and brief describe, the expected-returns approach forecasts the fiscal effects of a loan by projecting the government’s expected returns year by year, rather than collapsing them into a single value at the time the loan is made, as both FCRA and fair value do.

Expected returns accurately tracks the fiscal effects of lending over time, thus avoiding both fair value’s missing-money problem and FCRA’s magic-money-machine problem. It also provides a natural framework for reporting the fiscal effects of lending and the subsidies to borrowers. Expected returns would give policymakers and the public a more accurate assessment of federal lending than either of the approaches we use now.

Happy Tau Day

Blogging’s been very light of late, but I couldn’t let June 28th slip by without commemorating Tau Day.

Math aficionados often celebrate March 14 as Pi day, since Pi starts 3.14. All good fun. But as Michael Hartl argues over at the Tau Manifesto, Pi was likely a mistake. If we could rewrite math history, we’d do better to venerate tau, which equals 2 times pi, or about 6.28. So Happy Tau Day!

Hartl marshals multiple arguments in his manifesto. But the best reason is likely the simplest. The two most interesting things about a circle are its radius and its perimeter (aka circumference). If you divide the perimeter by the radius, you get tau. Nice and simple, without that pesky 2 that pops up through math and physics when pi rears its head.

CEA’s New Weekly Economic Index

The Council of Economic Advisers just released an interesting paper examining the macroeconomic harm from the government shutdown and debt limit brinksmanship. To do so, they created a Weekly Economic Index from data that are released either daily or weekly (and weren’t delayed by the shutdown). These data include measures of consumer sentiment, unemployment claims, retail sales, steel production, and mortgage purchase applications.

The headline result: They estimate that the budget showdown cost about 120,000 jobs by October 12.

Looking ahead, I wonder whether this index might prove useful in identifying future shocks to the economy, whether positive or negative. As the authors note:

In normal times estimating weekly changes in the economy is likely to detract from the focus on the more meaningful longer term trends in the economy which are best measured over a monthly, quarterly, or even yearly basis. But when there is a sharp shift in the economic environment, analyzing high-frequency changes with only a very short lag since they occurred can be very valuable.

P.S. I am pleased to see CEA come down on the right side of the “brinksmanship” vs. “brinkmanship” debate.

Uncle Sam Is Smaller (Relatively) Than We Thought

At 8:30 this morning, Uncle Sam suddenly shrunk.

Federal spending fell from 21.5 percent of gross domestic product to 20.8 percent, while taxes declined from 17.5 percent to 16.9 percent.

To be clear, the government is spending and collecting just as much as it did yesterday. But we now know that the U.S. economy is bigger than we thought. GDP totaled $16.2 trillion in 2012, for example, about $560 billion larger than the Bureau of Economic Analysis previously estimated. That 3.6 percent boost reflects the Bureau’s new accounting system, which now treats research and development and artistic creation as investments rather than immediate expenses.

In the days and months ahead, analysts will sort through these and other revisions (which stretch back to 1929) to see how they change our understanding of America’s economic history. But one effect is already clear: the federal budget is smaller, relative to the economy, than previously thought.

The public debt, for example, was on track to hit 75 percent of GDP at year’s end; that figure is now 72.5 percent. Taxes had averaged about 18 percent of GDP over the past four decades; now that figure is about 17.5 percent. Average spending similarly got marked down from 21 percent of GDP to about 20.5 percent.

These changes have no direct practical effect—federal programs and tax collections are percolating along just as before. But they will change how we talk about the federal budget.

Measured against an economy that is bigger than we thought, Uncle Sam now appears slightly smaller. Wonks need to update their budget talking points accordingly.

The Fed and America’s Debt

Is the Federal Reserve part of the government? You might think so, but you wouldn’t know it from the way we talk about America’s debt. When it comes to the debt held by the public, for example, the Fed is just a member of the public.

That accounting reflects the Fed’s unusual independence from the rest of government. The Fed remits its profits to the U.S. Treasury each year, but is otherwise ignored when thinking about fiscal policy.

In the era of quantitative easing, that accounting warrants a second look. The Fed now owns $2 trillion in Treasury bonds and $1.5 trillion in other financial assets. Those assets, and the way the Fed finances them, could have significant budget implications.

To understand them, we’ve calculated what the federal government’s debt and financial asset positions look like when you combine the regular government with the Federal Reserve, taking care to net out the debt owned by the Fed and Treasury cash deposited at the Fed:

This consolidated view offers five insights about America’s debt situation:

1. Less long-term debt. The Fed has bought $2 trillion of Treasury debt with maturities of a year or more. As a result, $2 trillion of medium- and long-term public debt is not, in fact, held by the real public. Interest payments continue, but they cycle from the Treasury to the Fed and then back again when the Fed remits its profits to Treasury. (This debt would become fully public again if the Fed ever decides to sell or allows the debt to mature without replacing it.)

2. More short-term debt. The Fed needs resources to buy longer-term Treasuries, mortgage-backed securities, and other financial assets. In the early days of the crisis response, it did so by selling the short-term Treasuries it owned. But those eventually ran out. So the Fed began financing its purchases by creating new bank reserves. Those reserves now account for $2 trillion of the Fed’s $2.3 trillion in short-term borrowing, on which it currently pays 0.25 percent interest.

3. Slightly more overall debt. The official public debt currently stands at $11.9 trillion. When we add in the Fed, that figure rises to $12.1 trillion. Bank reserves and other short-term Fed borrowings more than offset the Fed’s portfolio of Treasury bonds.

4. Lots more financial assets. Treasury’s financial assets now total $1.1 trillion. That figure more than doubles to $2.5 trillion when we add in the Fed’s mortgage-backed securities and other financial assets.

5. Less debt net of financial assets. The Fed adds more in financial assets than in government debt, so the debt net of financial assets falls from $10.8 trillion to $9.6 trillion. That $1.2 trillion difference reflects the power of the printing press. As America’s monetary authority, the Fed has issued $1.2 trillion in circulating currency to help finance its portfolio. That currency is technically a government liability, but it bears no interest and imposes no fiscal burden.

The Fed thus strengthens the government’s net financial position, but increases the fiscal risk of future increases in interest rates. When the Fed buys Treasuries, for example, it replaces long-term debts with very short-term ones, bank deposits. That’s been a profitable trade in recent years, with short-term interest rates near zero. But it means federal coffers will be more exposed to future hikes in short-term interest rates, if and when they occur.

Smart Tax Reform Could Shrink the Government

Max Baucus and Dave Camp, leaders of the Senate and House tax-writing committees, are on the road promoting tax simplification. One goal: cleaning out the mess of deductions, exclusions, credits, and other tax breaks that complicate the code.

Done well, such house cleaning could make for a simpler, fairer, more pro-growth tax code. It could also shrink government’s role in the economy. Eric Toder and I explore that theme in a recently released paper, Tax Policy and the Size of Government. Here’s our intro:

How big a role the government should play in the economy is always a central issue in political debates. But measuring the size of government is not simple. People often use shorthand measures, such as the ratio of spending to gross domestic product (GDP) or of tax revenues to GDP. But those measures leave out important aspects of government action. For example, they do not capture the ways governments use deductions, credits, and other tax preferences to make transfers and influence resource use.

We argue that many tax preferences are effec¬tively spending through the tax system. As a result, traditional measures of government size understate both spending and revenues. We then present data on trends in U.S. federal spending and revenues, using both traditional budget measures and measures that reclassify “spending-like tax preferences” as spending rather than reduced revenue. We find that the Tax Reform Act of 1986 reduced the government’s size significantly, but only temporarily. Spending-like tax prefer¬ences subsequently expanded and are now larger, relative to the economy, than they were before tax reform.

We conclude by examining how various tax and spending changes would affect different measures of government size. Reductions in spending-like tax preferences are tax increases in traditional budget accounting but are spending reductions in our expanded measure. Increasing marginal tax rates, in contrast, raises both taxes and spending in our expanded measure. Some tax increases thus reduce the size of government, while others increase it.

Eric and I first presented this line of reasoning in How Big is the Federal Government? in March 2012. Our latest paper, recently published in the conference proceedings of the National Tax Association, is a pithier presentation of those ideas.

Uncle Sam’s Trillion-Dollar Portfolio Partly Offsets the Public Debt

When policy folks talk about America’s federal borrowing, their go-to measures are the public debt, currently $12 trillion, and its ratio to gross domestic product, which is approaching 75 percent. Those figures represent the debt that Treasury has sold into public capital markets, pays interest on, and will one day roll over or repay.

These debt measures are important, but they paint an incomplete picture of America’s fiscal health. They don’t account for the current level of interest rates, for example, or for the trajectory of future revenues and spending. A third limitation, the focus of this post, is that the public debt doesn’t give Treasury any credit for the many financial assets it owns.

As we noted last week, Uncle Sam has been borrowing not only to finance deficits but also to make student loans, build up cash, and buy other financial assets. That portfolio now stands at $1.1 trillion, equivalent to almost one-tenth of the public debt.

Those assets have real value. They pay interest and dividends and could be sold if Treasury ever cared to. In fact, Treasury has sold many financial assets in recent years, including mortgage-backed securities and equity stakes in TARP-backed companies, even as it expanded its portfolio of student loans.

One way to take account of these holdings is to subtract their value from the outstanding debt. The rationale is straightforward. If Ann and Bob each owe $30,000 in student loans and have no other debts, they both have the same gross debt. But that doesn’t mean their financial situations are the same. If Ann has $10,000 in the bank and Bob has only $5,000, then Ann is in a stronger position. Her net debt is $20,000, while Bob’s is $25,000.

The same logic applies to the federal government: $12 trillion in debt is easier to bear if the government has some offsetting financial assets than if it has none. That’s why both the Office of Management and Budget and the Congressional Budget Office regularly report the public debt net of financial assets. The net debt isn’t a perfect measure; many assets are harder to value than Ann and Bob’s bank accounts, and official valuations may not fully reflect their risk. Nonetheless, as CBO has said, the net public debt provides “a more comprehensive picture of the government’s financial condition and its overall impact on credit markets” than does the gross public debt.

The net debt is now a bit less than $11 trillion or about 68 percent of GDP. That’s more than $1 trillion less than the usual, gross measure of public debt, or about 7 percent of GDP. That difference was only 3 percent of GDP as recently as 2006. Under President Obama’s budget, it would expand to almost 10 percent by 2023, with financial assets growing twice as fast as the public debt.

Financial assets are thus playing a bigger role in America’s debt story. Accumulating deficits remain the prime driver of the debt. But the expansion of Uncle Sam’s investment portfolio means the growing public debt overstates America’s debt burden.

Using Economics to Explain Temperatures Below Absolute Zero

In high school, I learned that absolute zero (about -460° Fahrenheit or -273° Celsius) is as cold as you can get. At that point, all motion ceases, and you can’t get any colder.

So it was a bit of a head-scratcher to learn that physicists recently created a gas whose temperature is below absolute zero. Seems impossible, right?

Well, no. Turns out that the high-school definition of absolute zero doesn’t capture the modern notion of temperature. As Empirical Zeal explains, temperature isn’t only about motion, it’s about an object’s willingness to give up energy. And physicists have been creating negative-temperature objects for more than 60 years.

Measurement is a recurring theme on this blog, so I found this intriguing. All those years, and I didn’t actually know how physicists really measure temperature. But what really caught my eye is that Empirical Zeal uses some ideas from economics to explain what negative temperatures are all about.

Using the ideas of exchange, marginal utility, and utility maximization, he illustrates how negative temperatures are like a world in which the Dalai Lama should give all his money to Warren Buffett.
