BHC expansion into nonbank financial activities may increase or decrease the standard deviation of BHC ROA and/or the probability of bankruptcy of the BHC. Using individual firm data and a new application of a simulated merger methodology, I find the standard deviation minimizing and bankruptcy...

Under the strong-form of market discipline, publicly traded banks that have constantly available public market signals from their stock (and bond) prices would take less risk than non-publicly traded banks because counterparties, borrowers, and regulators could react to adverse public market...

One reason why countries service their external debts is the fear that default might lead to shrinkage of international trade. If so, then creditors should systematically lend more to countries with which they share closer trade links. We develop a simple theoretical model to capture this...

What has been the effect of the shift in emerging market capital flows toward private sector borrowers? Are emerging market capital flows more efficient? If not, can controls on capital flows improve welfare? This paper shows that the answers depend on the form of default risk. When private...

Covariance matrix forecasts of financial asset returns are an important component of current practice in financial risk management. A wide variety of models, ranging from matrices of simple summary measures to covariance matrices implied from option prices, are available for generating such...

This paper uses household consumption data to investigate whether uninsurable idiosyncratic risk accounts for the equity premium. The analysis complements and extends prior empirical work by relaxing maintained assumptions about idiosyncratic income shocks. Following Mankiw (1986), the paper...

One plausible mechanism through which financial market shocks may propagate across countries is through the effect of past gains and losses on investors’ risk aversion. The paper first presents a simple model examining how heterogeneous changes in investors’ risk aversion affects portfolio...

This paper examines the properties of X-inefficiencies in U.S. banking firms. We find that, after controlling for scale differences, the average small size banking firm is less efficient than the aerate large firm. Smaller firms also exhibit higher variation in X-inefficiencies than their larger...
