Knowledge that Transforms

We examine the link between the excess value of a diversified firm and the value of its internal capital market. Subsidies to small financially constrained segments with good relative investment opportunities significantly increase excess value, while transfers of resources from segments with good relative investment opportunities significantly decrease excess value. Of interest is that subsidies to small financially constrained segments with poor relative investment opportunities also significantly increase excess value. However, there is little evidence that this result depends on the diversity of a firm's investment opportunities. We conclude that financing constraints drive the relationship between the internal capital market and firm value.

We present a detailed view of market quality in the presence of preferencing arrangements. A unique dataset provides the opportunity to measure trading costs of marketable orders and fill rates and ex post costs of limit orders across trading venues. For market orders, we find the primary exchange provides the lowest execution costs. However, the preferencing exchanges are no worse than, and in most cases better than, the nonpreferencing regional exchanges. For limit orders, the regionals execute limit orders more frequently than the primary market and with an ex post execution cost that is not very different from the primary market.

This article studies the impact of imperfect consumption risk sharing across countries on the formation of time-varying risk premiums in the foreign exchange market and on their cross-sectional differences. These issues are addressed within the framework of the Constantinides and Duffie (1996) model applied to a multicountry world. The article shows that the cross-country variance of consumption growth rates is counter-cyclical and that this feature of consumption data is mildly helpful for currency pricing. In particular, unlike the standard CCAPM, the new model is able to generate currency risk premiums at lower values of risk aversion and provide certain explanatory power for cross-sectional differences in currency returns.

This article is a critical survey of models designed for pricing fixed-income securities and their associated term structures of market yields. Our primary focus is on the interplay between the theoretical specification of dynamic term structure models and their empirical fit to historical changes in the shapes of yield curves. We begin by overviewing the dynamic term structure models that have been fit to treasury or swap yield curves and in which the risk factors follow diffusions, jump-diffusion, or have "switching regimes." Then the goodness-of-fit of these models is assessed relative to their abilities to (i) match linear projections of changes in yields onto the slope of the yield curve; (ii) match the persistence of conditional volatilities, and the shapes of term structures of unconditional volatilities, of yields; and (iii) to reliably price caps, swaptions, and other fixed-income derivatives. For the case of defaultable securities we explore the relative fits to historical yield spreads.

We investigate whether the volatility risk premium is negative by examining the statistical properties of delta-hedged option portfolios (buy the option and hedge with stock). Within a stochastic volatility framework, we demonstrate a correspondence between the sign and magnitude of the volatility risk premium and the mean delta-hedged portfolio returns. Using a sample of S&P 500 index options, we provide empirical tests that have the following general results. First, the delta-hedged strategy underperforms zero. Second, the documented underperformance is less for options away from the money. Third, the underperformance is greater at times of higher volatility. Fourth, the volatility risk premium significantly affects delta-hedged gains, even after accounting for jump fears. Our evidence is supportive of a negative market volatility risk premium.

This article reviews tax research related to domestic and multinational capital structure, payout policy, compensation policy, risk management, and organizational form. For each topic, the theoretical arguments explaining how taxes can affect corporate decision making and firm value are reviewed, followed by a summary of the related empirical evidence and a discussion of unresolved issues. Tax research generally supports the hypothesis that high tax rate firms pursue policies that provide tax benefits. Many issues remain unresolved, however, including understanding whether tax effects are of first-order importance, why firms do not pursue tax benefits more aggressively, and whether corporate actions are affected by investor-level taxes.

This article studies an intertemporal economy with liquidity constrained and unconstrained individuals. We use a stopping time approach to solve the finite horizon-constrained consumption portfolio problem with constant relative risk aversion and to examine the structure of equilibrium. The impact of the constraint on the optimal consumption and the financing portfolio is assessed. The equilibrium state price density is related to the exercise boundary of an American-style contingent claim with nonlinear payoff. This stopping time characterization enables us to prove the existence of an equilibrium and can be implemented numerically. Properties of equilibrium bond and stock returns are examined.

In sharp contrast to results in the United States, the average stock price response to an announcement of a seasoned equity issue in Japan is positive. Offer prices in Japan, unlike the United States, are announced several days before the beginning of the subscription period and incorporate a substantial discount. We suggest that the positive announcement effects in Japan are consistent with the underwriter's certification of the issuing firm's value. We characterize the underwriter's risk as a put option and find a positive association between the underwriter's risk and the announcement returns, as well as other results consistent with underwriter certification.

The effects of competitive interactions on investment decisions and on the dynamics of the price of a nonstorable commodity are studied in a model of incremental investment with time to build and operating flexibility. I find that an increase in uncertainty may encourage firms to increase their capacity. Furthermore, I show that it may be optimal to invest in additional capacity during periods in which part of the operational capacity is not being utilized. The impact of competition on the properties of the endogenous output price is dramatic. For example, I find that price volatility may be increasing in the number of competitors in the industry.

Market returns before the offer price is set affect the amount and variability of initial public offering (IPO) underpricing. Thus an important question is "What IPO procedure is best adapted for controlling underpricing in "hot" versus "cold" market conditions?" The French stock market offers a unique arena for empirical research on this topic, since three substantially different issuing mechanisms (auctions, bookbuilding, and fixed price) are used there. Using 1992-1998 data, we find that the auction mechanism is associated with less underpricing and lower variance of underpricing. We show that the auction procedure's ability to incorporate more information from recent market conditions into the IPO price is an important reason.
