This paper develops a new estimation procedure for characteristic-based factor models of security returns. We treat the factor model as a weighted additive nonparametric regression model, with the factor returns serving as time-varying weights, and a set of univariate non-parametric functions...

We examine the impact of market dispersion on the performance of hedge funds. Market dispersion is measured by the cross-sectional volatility of equity returns in a given month.Using hedge fund indices and a panel of monthly returns on individual hedge funds, we find that market dispersion and...

This paper develops a simple model of the gap between socially and privately optimal bank lending when a bank has an overhang of impaired loans, and analyzes government policies designed to close this gap. The impaired loans have risky cash flows but observable market values. A number of basic...

This paper develops a restrictive procedure for evaluating economic policy decisions, by comparing actual economic history to a simulated history where a specific policy decision is replaced with a counterfactual, but credible, alternative. Our procedure is theoretically straightforward, but...
