As a result of the pandemic, U.S. general government debt (federal, state, and local obligations combined) has surged above 130 percent of GDP, more than double what it was in 2007. And, recent U.S. experience is far from unique. Looking at the G20, average public debt rose from 52% of GDP in 2007 to 74% in 2019 and is projected to reach 91% next year.

Unsurprisingly, as government debt increases, the debate over public spending heats up. Are these high debt ratios sustainable? Should we be cutting spending and raising taxes to reduce what will otherwise be a large financial burden on future generations?

In this post, we emphasize that not all government spending is created equal. Investment in physical infrastructure, as well as in education and health—especially for children—can boost future GDP. Moreover, delaying inevitable outlays can boost long-run costs. As a result, a failure to make productive, self-financing investments due to concerns about the debt would be not only tragic, but counterproductive….

What's in store for r*?

It is amazing how things we once thought impossible, or at least extremely improbable, can become commonplace. Ten-year government bond yields in most of Europe and Japan are at or below zero. And, for U.S. Treasurys, the yield has been below 1 percent since March.

A confluence of factors has come together to deliver these incredibly low interest rates. Most importantly, inflation is far lower and much more stable than it was 30 years ago. Second, monetary policy remains extremely accommodative, with policy rates stuck around zero (or below!) for the past decade in Europe and Japan, and only temporarily higher in the United States. Third, the equilibrium (or natural) real interest rate (r*)—the rate consistent in the longer run with stable inflation and full employment—has fallen by roughly 2 percentage points since 2008 and is now only 0.5% or lower.

How long will this go on? What’s in store for r*? Focusing on the United States, in this post we discuss the large post-2007 decline in r* that followed a gradual downward trend in prior decades. After considering various possible explanations, we focus on the change in U.S. saving behavior. Around 2008, there was an abrupt increase in household savings relative to wealth and income. Combined with increased foreign demand for U.S. assets, this appears to be a key culprit behind the recent fall in r*.

We doubt that this will change anytime soon….

Fiscal Space Has Limits, Too

In the battle against the economic impact of COVID-19, governments around the world are pulling out all the stops. In advanced economies, leading central banks have pushed interest rates to zero or below. And, a recent IMF estimate puts the combination of discretionary spending and automatic fiscal stabilizers (including unemployment insurance and progressive income taxation) at $9 trillion―more than 10 percent of global GDP.

With bond yields low or negative, the limits to monetary policy are clear (see our pre-COVID post). How large is the scope for additional countercyclical fiscal policy? With sovereign yields so low, the cost of additional financial expansion looks to be minimal, at least for now (see, for example, Blanchard).

Nevertheless, each time public debt-to-GDP ratios ratchet higher—as they did in the 2007-09 crisis and are now doing again—the question of “fiscal space” reemerges. When the next economic shock hits, will governments again be able to provide relief and stimulus on the scale required to meet society’s needs?

In this post, we highlight recent fiscal developments in advanced economies, and review the factors affecting the sustainability of their high and rising levels of debt. To foreshadow our conclusion, the fact that many countries’ fiscal positions were precarious even before the COVID crisis does not weaken the current case for stimulus. But, doubts about fiscal space are growing. So, it is important that governments find a way to make a credible commitment to future fiscal consolidation when their economies have returned to full employment. Failure to do so could threaten confidence both in government finances and in economic performance….

The Case for Strengthening Automatic Fiscal Stabilizers

For decades, monetary economists viewed central banks as the “last movers.” They were relatively nimble in their ability to adjust policy to stabilize the economy as signs of a slowdown arose. In contrast, discretionary fiscal policy is difficult to implement quickly. In addition, allowing for the possibility of a constantly changing fiscal stance adds to uncertainty and raises the risk that short-run politics, rather than effective use of public resources, will drive policy. So, the ideal fiscal approach was to set policy to support long-run priorities, minimizing short-run discretionary changes that can reduce economic efficiency.

Today, because conventional monetary policy has little room to ease, the case for using fiscal policy as a cyclical stabilizer is far stronger. Unless something changes, there is a good chance that when the next recession hits, monetary policymakers will once again find themselves stuck for an extended period at the lower bound for policy rates. In the absence of a monetary policy offset, fiscal policy is likely to be significantly more effective.

Against this background, a new book from The Hamilton Project and the Washington Center for Equitable Growth, Recession Ready: Fiscal Policies to Stabilize the American Economy, makes a compelling case for strengthening automatic fiscal stabilizers. These are the tax, transfer and spending components that change with economic conditions, as the law prescribes….

Italeave: The Renewed Threat of a Parallel Currency

In the March 2018 general election, two Italian political parties (the League and the Five Star Movement) that eventually formed the current government campaigned against many of the structures that are the foundation of the European Union. One part of their agreed policy program, a proposal that resurfaced in the past week, concerns the possibility of issuing mini-BOTs (which stands for Buoni del Tesoro). These would be small denomination “bonds”—non-interest-bearing, tradeable securities—issued by the Italian government to pay debts and usable to pay taxes or purchase goods and services provided by the state. Printed in the size and shape of currency notes, recipients could view them as a new means of exchange.

In this post, we discuss the possibility of Italy leaving the European Monetary Union, and why there is an increased incentive for the government to plan for an abrupt and unanticipated exit. The strategic analogy is to the appearance of a first-strike capacity that undermines nuclear peace. In our view, however, that appearance is misleading: any attempt to exit would not only be a disaster for Italy, as we explained in our post from a year ago, it would be the “mother of all financial crises” ….

Italeave: Mother of all financial crises

After years of calm, fears of a currency redenomination—prompted by the attitudes toward monetary union of Italy’s now-governing parties and the potential for another round of early elections—revived turbulence in Italian markets last week. We have warned in the past that an Italian exit from the euro would be disastrous not only for Italy, but for many others as well (see our earlier post).

And, given Italy’s high public debt, a significant easing of its fiscal stance within monetary union could revive financial instability, rather than boost economic growth. Depositors fearing the introduction of a parallel currency (to finance the fiscal stimulus) would have incentive to shift out of Italian banks into “safer” jurisdictions. Argentina’s experience in 2001, when the introduction of quasi-moneys by the fiscal authorities undermined monetary control, is instructive….
