I study how unsecured credit affects the extent to which unemployment insurance (UI) policies smooth cyclical fluctuations in aggregate consumption. To do so, I develop a real business cycle model with incomplete asset markets, frictional labor markets, and defaultable debt. Using empirically...

Using micro data from the U.S. Consumer Expenditure Survey and Current Population Survey, I document that government spending shocks affect individuals differently over the life cycle. Young households increase their consumption after an expansionary shock while prime-age households reduce it,...

Over the last few decades, real interest rates have trended downward in many countries. The most common explanation is that this reflects depressed demand due to demographic, technological and other real factors such as income inequality. In this paper we explore the claim that these trends may...

This paper studies how the credit expansion policy pursued by the Chinese government in an effort to stimulate its economy in the post-crisis period affects bank-firm loan contracts and the macroeconomy. We build a structural model with financial frictions in which the optimal loan contract...

In the United States, 30% of households are coholders who simultaneously borrow on credit cards and hold liquid assets. This generates a rich distribution of gross wealth positions that underpins the distribution of net wealth often used to calibrate macroeconomic models. We show that, beyond...

We show how to use optimal control theory to derive optimal time-consistent Markov-perfect government policies in nonlinear dynamic general equilibrium models, extending the result of Cohen and Michel (1988) for models with quadratic objective functions and linear dynamics. We replace private...

This paper studies the impact government expenditure has on inflation by examining an augmented Phillips curve implied from a structural New Keynesian model, Our estimation results, based on external instruments, show that the augmented Phillips curve has a flatter slope than the canonical...

We build an otherwise-standard business cycle model with housework, calibrated consistently with data on time use, in order to discipline consumption-hours complementarity and relate its strength to the size of fiscal multipliers. We show that if substitutability between home and market goods is...
