Should the generosity of unemployment benefits and the progressivity of income taxes depend on the presence of business cycles? This paper proposes a tractable model where there is a role for social insurance against uninsurable shocks to income and unemployment, as well as business cycles that are inefficient due to the presence of matching frictions and nominal rigidities. We derive an augmented Baily–Chetty formula showing that the optimal generosity of the social insurance system depends… 
Uninsured Unemployment Risk and Optimal Monetary Policy
I study optimal monetary policy in a New Keynesian economy wherein house- holds precautionary-save against uninsured, endogenous unemployment risk. In this economy greater unemployment risk raises
Unemployment Insurance and Macroeconomic Stabilization
Unemployment insurance (UI) provides an important cushion for workers who lose their jobs. In addition, UI may act as a macroeconomic stabilizer during recessions. This chapter examines this UI’s
Taking off into the Wind: Unemployment Risk and State-Dependent Government Spending Multipliers
We propose a model with involuntary unemployment, incomplete markets, and nominal rigidity, in which the effects of government spending are state-dependent. An increase in government purchases raises
Automatic Stabilization and Labor Supply
This paper estimates the stabilizing effects of tax and transfers systems through a marginal incentives channel. When income taxes are progressive, the tax rate that a household faces will fall
Unemployment Insurance and Unsecured Credit
In many countries, an unemployed has access to both public (unemployment insurance, UI) and private (credit card borrowing) form of insurance, and recent research suggests interactions between the
Optimal Progressive Income Taxation in a Bewley-Grossman Framework
We study optimal income tax progressivity in an environment where individuals are exposed to idiosyncratic income and health risks over the lifecycle. Our results, based on a calibration for the US
The Macroeconomic Effects of Progressive Taxes and Welfare
We analyze the positive and normative effects of a progressive tax on wages in a nonlinear New Keynesian DSGE model in the presence of demand and technology shocks. The non-linearity allows us to
Consumer Spending During Unemployment: Positive and Normative Implications
Using de-identified bank account data, we show that spending drops sharply at the large and predictable decrease in income arising from the exhaustion of unemployment insurance (UI) benefits. We use

Unemployment Insurance in Macroeconomic Stabilization
Does the generosity of unemployment insurance (UI) have a role to play in macroeconomic stabilization? When inefficient fluctuations arise from nominal rigidities and constraints on monetary policy,
The Importance of Unemployment Insurance as an Automatic Stabilizer
We assess the extent to which unemployment insurance (UI) serves as an automatic stabilizer to mitigate the economy's sensitivity to shocks. Using a local labor market design based on heterogeneity
Optimal Unemployment Insurance Over the Business Cycle
This paper analyzes optimal unemployment insurance over the business cycle in a search model in which unemployment stems from matching frictions (in booms) and job rationing (in recessions). Job
Pro-Cyclical Unemployment Benefits? Optimal Policy in an Equilibrium Business Cycle Model
We study the optimal provision of unemployment insurance (UI) over the business cycle. We consider an equilibrium Mortensen-Pissarides search and matching model with risk-averse workers and aggregate
A Macroeconomic Theory of Optimal Unemployment Insurance
We develop a theory of optimal unemployment insurance (UI) that accounts for workers’ job-search behavior and firms’ hiring behavior. The optimal replacement rate of UI is the conventional Baily

Unemployment (Fears) and Deflationary Spirals
The interaction of incomplete markets and sticky nominal wages is shown to magnify business cycles even though these two features – in isolation – dampen them. During recessions, fears of
Optimal Tax Progressivity: An Analytical Framework
What shapes the optimal degree of progressivity of the tax and transfer system? On the one hand, a progressive tax system can counteract inequality in initial conditions and substitute for imperfect

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ
