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….

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….

Trump v. Fed

Last month, interrupting decades of presidential self-restraint, President Trump openly criticized the Federal Reserve. Given the President’s penchant for dismissing valuable institutions, it is hard to be surprised. Perhaps more surprising is the high quality of his appointments to the Board of Governors. Against that background, the limited financial market reaction to the President’s comments suggests that investors are reasonably focused on the selection of qualified academics and individuals with valuable policy and business experience, rather than a few early-morning words of reproof.

Nevertheless, the President’s comments are seriously disturbing and—were they to become routine—risk undermining the significant benefits that Federal Reserve independence brings. Importantly, the criticism occurred despite sustained strength in the economy and financial markets, and despite the stimulative monetary and fiscal policies in place….
