September 2005Estimating Bank Trading Risk: A Factor Model Approach
with James O'Brien: w11608
Risk in bank trading portfolios and its management are potentially important to the banks%u2019 soundness and to the functioning of securities and derivatives markets. In this paper, proprietary daily trading revenues of 6 large dealer banks are used to study the bank dealers%u2019 market risks using a market factor model approach. Dealers%u2019 exposures to exchange rate, interest rate, equity, and credit market factors are estimated. A factor model framework for variable exposures is presented and two modeling approaches are used: a random coefficient model and rolling factor regressions. The results indicate small average market exposures with significant but relatively moderate variation in exposures over time. Except for interest rates, there is heterogeneity in market exposures acros...


June 2002Bankruptcy and Small Firms' Access to Credit
with Michelle J. White: w9010
In this paper, we investigate how personal bankruptcy law affects small firms' access to credit. When a firm is unincorporated, its debts are personal liabilities of the firm's owner, so that lending to the firm is legally equivalent to lending to its owner. If the firm fails, the owner has an incentive to file for personal bankruptcy, since the firm's debts will be discharged and the owner is only obliged to use assets above an exemption level to repay creditors. The higher the exemption level, the greater is the incentive to file for bankruptcy. We show that supply of credit falls and demand for credit rises when non-corporate firms are located in states with higher bankruptcy exemptions. We test the model and find that, if small firms are located in states with unlimited rather than...

February 1995Dynamic Equilibrium Economies: A Framework for Comparing Models and Data
with Francis X. Diebold, Lee E. Ohanian: t0174
Many recent theoretical papers have come under attack for modeling prices as Geometric Brownian Motion. This process can diverge over time, implying that firms facing this price process can earn infinite profits. We explore the significance of this attack and contrast investment under Geometric Brownian Motion with investment assuming mean reversion. While analytically more complex, mean reversion in many cases is a more plausible assumption, allowing for supply responses to increasing prices. We show a mean reversion process rather than Geometric Brownian Motion and provide an explanation for this result.
