In HANK, we show that fiscal policy is an appropriate macroeconomic stabilization tool at the ZLB. Fiscal policy achieves the same macroeconomic aggregates and the same welfare as hypothetically unconstrained monetary policy by replicating its transmission mechanism. Consumption taxes and labor...

We build a New Keynesian business-cycle model with rich household heterogeneity. In the model, systematic monetary stabilization policy affects the distribution of income, income risks, and the demand for funds and supply of assets: the demand, because matching frictions render idiosyncratic...

We show that in a New Keynesian model with household heterogeneity, fiscal policy can be a perfect substitute for monetary policy: three simple conditions for consumption taxes, labor taxes, and the government debt level are sufficient to induce the same consumption and labor supply of each...

We analyze the macroeconomic implications of increasing the top marginal income tax rate using a dynamic general equilibrium framework with heterogeneous agents and a fiscal structure resembling the actual US tax system. The wealth and income distributions generated by our model replicate the...

We analyze the macroeconomic implications of increasing the top marginal income tax rate using a dynamic general equilibrium framework with heterogeneous agents and a fiscal structure resembling the actual U.S. tax system. The wealth and income distributions generated by our model replicate the...

We argue that the fiscal multiplier of government purchases is increasing in the spending shock, in contrast to what is assumed in most of the literature. The fiscal multiplier is largest for large positive government spending shocks and smallest for large contractions in government spending. We...

A two-sector incomplete markets model with heterogeneous agents can be used to study the distributional effects of the COVID-19 lockdown. While negative aggregate welfare effects of the lockdown are unavoidable, the size of aggregate welfare effects as well as the distribution of the welfare...

We use regional variation in the American Recovery and Reinvestment Act (2009-2012) to analyze the effect of government spending on consumer spending. Our consumption data come from household-level retail purchases in Nielsen and auto purchases from Equifax credit balances. We estimate that a $1...
