As a result of the BoJ's large-scale asset purchases, the consolidated Japanese government borrows mostly at the floating rate from households and invests in longer-duration risky assets to earn an extra 3% of GDP. We quantify the impact of Japan's low-rate policies on its government and...

Monetary and fiscal policies require coordination to achieve desired macroeconomic outcomes. The literature since Leeper (1991) has focused on two regimes: monetary dominance and fiscal dominance. In both cases, one policy is active while the other is passive and accommodates the former. We...

This paper studies the macroeconomic effects of energy price shocks in energy-importing economies using a heterogeneous-agent New Keynesian model. When MPCs are realistically large and the elasticity of substitution between energy and domestic goods is realistically low, increases in energy...

We show that the largest increase in unemployment benefits in U.S. history had large spending impacts and small job-finding impacts. This finding has three implications. First, increased benefits were important for explaining aggregate spending dynamics--but not employment dynamics--during the...

The fiscal theory states that inflation adjusts so that the real value of government debt equals the present value of real primary surpluses. Monetary policy remains important. The central bank can set an interest rate target, which determines the path of expected inflation, while news about the...

I reconsider the long-standing consensus view that macroeconomic stabilization should rely on monetary policy, not fiscal policy. I use an analytically tractable heterogeneous agent New Keynesian (HANK) model that is parameterized so as to admit a bubble in public debt. In this context, I show...

Many consumers below the top of the distribution of a representative population by cognitive abilities barely react to monetary and fiscal policies that aim to stimulate consumption and borrowing, even when they are financially unconstrained and despite substantial debt capacity. Differences in...

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...

This paper examines the association between episodes of large fiscal impulses (expansions and adjustments) and sustainable development indicators (prosperity, resilience, and inclusivity). We provide country studies of Chile, Poland, South Africa, and Thailand, examining the components of...

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...
