We develop a model of optimal schooling investments and estimate it using new data on approximately 700 identical twins. We estimate an average return to schooling of 9 percent for identical twins, but estimated returns appear to be slightly higher for less able individuals. Simple cross-section estimates are marginally upward biased. These empirical results imply that abler individuals attain more schooling because they face lower marginal costs of schooling, not because of higher marginal benefits.

Abstract A three parameter stochastic process, termed the variance gamma process, that generalizes Brownian motion is developed as a model for the dynamics of log stock prices. Theprocess is obtained by evaluating Brownian motion with drift at a random time given by a gamma process. The two additional parameters are the drift of the Brownian motion and the volatility of the time change. These additional parameters provide control over the skewness and kurtosis of the return distribution. Closed forms are obtained for the return density and the prices of European options.The statistical and risk neutral densities are estimated for data on the S&P500 Index and the prices of options on this Index. It is observed that the statistical density is symmetric with some kurtosis, while the risk neutral density is negatively skewed with a larger kurtosis. The additional parameters also correct for pricing biases of the Black Scholes model that is a parametric special case of the option pricing model developed here.

We develop a framework for analyzing the capital allocation and capital structure decisions facing financial institutions. Our model incorporates two key features: (i) value-maximizing banks have a well-founded concern with risk management; and (ii) not all the risks they face can be frictionlessly hedged in the capital market. This approach allows us to show how bank-level risk management considerations should factor into the pricing of those risks that cannot be easily hedged. We examine several applications, including: the evaluation of proprietary trading operations, and the pricing of unhedgeable derivatives positions. We also compare our approach to the RAROC methodology that has been adopted by a number of banks.

This study examines the usefulness of an analyst-based valuation model in predicting cross-sectional stock returns. We estimate firms' fundamental values (V) using I/B/E/S consensus forecasts and a residual income model. We find that V is highly correlated with contemporaneous stock price, and that the V/P ratio is a good predictor of long-term cross-sectional returns. This effect is not explained by a firm's market beta, B/P ratio, or total market capitalization. In addition, we find errors in consensus analyst earnings forecasts are predictable, and that the predictive power of V/P can be improved by incorporating these errors.

[This study investigates whether the net deferred tax liabilities disclosed under Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS No. 109) provides additional value-relevant information over the disclosure required by Accounting Principles Board Opinion No. 11, Accounting for Income Taxes (APB No. 11). Evidence suggests that SFAS No. 109 data represent value-relevant information above and beyond APB No. 11. Additionally, evidence indicates that the changes made by SFAS No. 109-the separate recognition of deferred tax assets, the creation of valuation allowances for deferred tax assets and the adjustment of deferred tax accounts for enacted tax rate changes-each provide value-relevant firm data. These results suggest that SFAS No. 109 increased the value-relevance of deferred tax amounts in financial statements.]

Abstract This study investigates whether the net deferred tax liabilities disclosed under Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS No. 109) provides additional value-relevant information over the disclosure required by Accounting Principles Board Opinion No. 11, Accounting for Income Taxes (APS No. 11). Evidence suggests that SEAS No. 109 data represent value-relevant information above and beyond APB No. 11. Additionally, evidence indicates that the changes made by SFAS No. 109-the separate recognition of deferred tax assets, the creation of valuation allowances for deferred tax assets and the adjustment of deferred tax accounts for enacted tax rate changes-each provide value-relevant firm data. These results suggest that SFAS No. 109 increased the value-relevance of deferred tax amounts in financial statements.

This paper presents a model of incentive compatible bank regulation under moral hazard and adverse selection. We derive a wide range of simple and conceptually implementable mechanisms that can solve each type of incentive problem separately and also achieve the first-best outcome – but only when regulatory instruments involve ex post pricing that is contingent on the bank's performance relative to the market. An important feature of these mechanisms is that they do not involve a subsidy to the bank. When the regulator faces both moral hazard and adverse selection simultaneously, we identify the conditions under which the same mechanism can achieve the first-best solution.
