This paper is about the size of fiscal multipliers and the sources of recovery from the Great Depression. Its baseline result is that 89.1 percent of the 1939:Q1-1941:Q4 recovery can be attributed to fiscal policy innovations, 34.1 percent to monetary policy innovations and the remaining -23.2...

This paper surveys the recent literature on the theory of macroeconomic policy. We study the effect of various incentive constraints on the policy making process, such as lack of credibility, political opportunism, political ideology, and divided government. The survey is organized in three...

We study the effects of fiscal policy in response to the COVID-19 pandemic at the firm, sector, country and global level. First, we estimate the impact of COVID-19 and policy responses on small and medium sized enterprise (SME) business failures. We combine firm-level financial data from 50...

Governments around the world have gone on a massive fiscal expansion in response to the Covid crisis, increasing government debt to levels not seen in 75 years. How will this debt be repaid? What role do conventional and unconventional monetary policy play? We investigate debt sustainability in...

This paper studies the public debt implications of a class of Aiyagari (1994)-Bewley (1977)-Huggett (1993) (ABH) models of incomplete insurance in which agents face a near-zero probability of a highly adverse outcome. In generic models of this kind, there exists a public debt bubble, so that the...

We investigate the implications of extra-normal government spending under the COVID-19 pandemic for commercial bank lending growth between 2019Q4 and 2020Q4 in a large sample of over 3000 banks from 71 countries. We control for pre-pandemic structural factors, bank characteristics and government...

This paper proposes a tractable framework to analyze fiscal space and the dynamics of government debt, with a possibly binding zero lower bound (ZLB) constraint. Without the ZLB, a greater primary deficit unambiguously raises debt. However, debt need not explode: When R G - φ, where φ is the...
