Staff Working Papers

Model Uncertainty and Wealth Distribution

Staff Working Paper 2019-48 Edouard Djeutem, Shaofeng Xu
This paper studies the implications of model uncertainty for wealth distribution in a tractable general equilibrium model with a borrowing constraint and robustness à la Hansen and Sargent (2008). Households confront model uncertainty about the process driving the return of the risky asset, and they choose robust policies.

The Role of Corporate Saving over the Business Cycle: Shock Absorber or Amplifier?

Staff Working Paper 2018-59 Xiaodan Gao, Shaofeng Xu
We document countercyclical corporate saving behavior with the degree of countercyclicality varying nonmonotonically with firm size. We then develop a dynamic stochastic general equilibrium model with heterogeneous firms to explain the pattern and study its implications for business cycles.

Volatility Risk and Economic Welfare

Staff Working Paper 2017-20 Shaofeng Xu
This paper examines the effects of time-varying volatility on welfare. I construct a tractable endogenous growth model with recursive preferences, stochastic volatility, and capital adjustment costs.

Interpreting Volatility Shocks as Preference Shocks

Staff Working Paper 2016-45 Shaofeng Xu
This paper examines the relationship between volatility shocks and preference shocks in an analytically tractable endogenous growth model with recursive preferences and stochastic volatility. I show that there exists an explicit mapping between volatility shocks and preference shocks, and a rise in volatility generates the same impulse responses of macroeconomic aggregates as a negative preference shock.

On the Welfare Cost of Rare Housing Disasters

Staff Working Paper 2015-26 Shaofeng Xu
This paper examines the welfare cost of rare housing disasters characterized by large drops in house prices. I construct an overlapping generations general equilibrium model with recursive preferences and housing disaster shocks.

An Equilibrium Analysis of the Rise in House Prices and Mortgage Debt

Staff Working Paper 2013-9 Shaofeng Xu
This paper examines the contributions of population aging, mortgage innovation and historically low interest rates to the sharp rise in U.S. house prices and mortgage debt between 1994 and 2005.
