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...

Over the past decade, commercial banks have devoted many resources to developing internal models to better quantify their financial risks and assign economic capital. These efforts have been recognized and encouraged by bank regulators; for example, the 1997 Market Risk Amendment (MRA) formally...

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...

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...

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...

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...
