Labor market equilibria under limited liability

This paper explores the impact of limited liability on labor market equilibria. Assuming risk-neutrality, the effect of limited liability on production decisions is neutral. It is demonstrated that neutrality of the production decision will not hold under safety-first type of risk aversion. In particular limited liability generally decreases usage of capital. The changes in the quality of labor depend on the magnitude of complementarity between capital and labor and on whether the output clasticity of labor is greater or less than unity. Hence it is possible for limited liability to decrease the usage of labor and capital and hence reduce output.     

A comparison of alternative models for estimating firm’s growth rate

The growth rate plays an important role in determining a firm’s asset and equity values, nevertheless the basic assumptions of the growth rate estimation model are less well understood. In this paper, we demonstrate that the model makes strong assumptions regarding the financing mix of the firm. In addition, we discuss various methods to estimate firms’ growth rate, including arithmetic average method, geometric average method, compound-sum method, continuous regression method, discrete regression method, and inferred method. We demonstrate that the arithmetic average method is very sensitive to extreme observations, and the regression methods yield similar but somewhat smaller estimates of the growth rate compared to the compound-sum method. Interestingly, the ex-post forecast shows that arithmetic average method (compound-sum method) yields the best (worst) performance with respect to estimating firm’s future dividend growth rate. Firm characteristics, like size, book-to-market ratio, and systematic risk, have significant influence on the forecast errors of dividend and sales growth rate estimation.     

Board meetings,committee structure,and firm value

In this study, we examine the determinants of board monitoring activity and its impact on firm value for a broad panel of firms over a six-year period from 1999 to 2005. During this period, Congress and the exchanges promulgated regulations that increased pressure upon firms for more independent and active boards. Economists have debated whether board activity and externally imposed regulations benefit or harm firms. We develop and examine several proxies for board monitoring and examine the relationship between board monitoring activity, firm characteristics, and firm value in a structural equation framework. One set of our proxies is based on the number of annual board and Audit Committee meetings. We show that prior performance, firm characteristics and governance characteristics are important determinants of board activity. We also show that the board monitoring is driven by corporate events, such as an acquisition or a restatement of financial statements. We find that board activity has a positive impact on firm value. Our results also indicate that the external pressure has had a salutary effect and recent regulations have led to some increase in firm value. A second set of proxies is based on the shift to a fully independent Audit, Compensation and Nominating Committees. We find that firms increased the independence of these Board committees following the enactment of the 2002 Sarbanes-Oxley Act.     

COMMERCIAL BANK RISK: MARKET,INTEREST RATE,AND FOREIGN EXCHANGE

Because of recent structural changes in the balance sheets of banks, regulatory changes in the risk-based capital requirements, and the recent adoption of mark-to-market accounting changes, interest rate risk remains an important issue for commercial banks and an important regulatory concern. Market, interest rate, and foreign exchange risk are estimated for a sample of commercial banks using ordinary least squares from 1986 to 1991. Consistent with earlier studies, the estimated coefficients continue to be unstable. We find that interest rate risk decreases and foreign exchange risk increases. Moreover, the results differ depending on practices of the bank (money center, superregional, or regional). We find evidence consistent with earlier studies that theorize foreign exchange risk is explained by unhedged foreign loan exposure.     

Interest Rate Risk and the Optimal Gap for Commercial Banks: An Empirical Study

The optimal gap of a depository institution is derived using a market value optimization model. The gap is estimated using portfolios of returns on rate-sensitive assets and liabilities and is found to be not significantly different from zero. The estimate is compared to the average gap position of a sample of banks. It is found that the average gap position of a sample of banks is “too positive.” This suggests that banks are not showing risk minimization behavior in the positioning of the gap.
