Working Paper
Credit, bankruptcy, and aggregate fluctuations
We ask two questions related to how access to credit affects the nature of business cycles. First, does the standard theory of unsecured credit account for the high volatility and procyclicality of credit and the high volatility and countercyclicality of bankruptcy filings found in U.S. data? Yes, it does, but only if we explicitly model recessions as displaying countercyclical earnings risk (i.e., rather than having all households fare slightly worse than normal during recessions, we ensure that more households than normal fare very poorly). Second, does access to credit smooth aggregate ...

Beliefs, Aggregate Risk, and the U.S. Housing Boom
Endogenously optimistic beliefs about future house prices can account for the path and standard deviation of house prices in the U.S. housing boom of the 2000s. In a general equilibrium model with incomplete markets and aggregate risk, agents form beliefs about future house prices in response to shocks to fundamentals. In an income expansion with looser credit conditions, agents are more likely to underpredict house prices and revise up their beliefs. Matching the standard deviation and steady rise in house prices results in homeownership becoming less affordable later in the boom as well as ...

Monetary Policy with Racial Inequality
I develop a heterogeneous-agent New-Keynesian model featuring racial inequality in income and wealth, and studies interactions between racial inequality and monetary policy. Black and Hispanic workers gain more from accommodative monetary policy than White workers mainly due to higher labor market risks. Their gains are larger also because of a larger proportion of them are hand-to-mouth, while wealthy White workers gain more from asset price appreciation. Monetary and fiscal policies are substitutes in providing insurance against cyclical labor market risks. Racial minorities gain even more ...

Optimal Public Debt with Life Cycle Motives
Public debt can be optimal in standard incomplete market models with infinitely lived agents, since the associated capital crowd-out induces a higher interest rate. The higher interest rate encourages individuals to save and, hence, better self-insure against idiosyncratic labor earnings risk. Even though individual savings behavior is a crucial determinant of the optimality of public debt, this class of economies abstracts from empirically observed life cycle savings patterns. Thus, this paper studies how incorporating a life cycle affects optimal public debt. We find that while the ...

Generational War on Inflation: Optimal Inflation Rates for the Young and the Old
How does a grayer society affect the political decision-making regarding inflation rates? Is deflation preferred as a society ages? In order to answer these questions, we compute the optimal inflation rates for the young and the old respectively, and explore how they change with demographic factors, by using a New Keynesian model with overlapping generations. According to our simulation results, there indeed exists a tension between the young and the old on the optimal inflation rates, with the optimal inflation rates differing between generations. The rates can be significantly different ...
