Knowledge that Transforms

This paper analyzes the relation between real stock returns and real activity from 1889–1988. It replicates Fama's (1990) results for the 1953–1987 period using an additional 65 years of data. It also compares two measures of industrial production in the tests: (1) the series produced by Babson for 1889–1918, spliced with the Federal Reserve Board index of industrial production for 1919–1988, and (2) the new Miron and Romer (1989) index spliced with the Federal Reserve Board index in 1941. Fama's findings are robust for a much longer period—future production growth rates explain a large fraction of the variation in stock returns. The new Miron-Romer measure of industrial production is less closely related to stock price movements than the older Babson and Federal Reserve Board measures.

This paper demonstrates how the incentive of manager-equityholders to substitute toward riskier assets, commonly referred to as the “asset substitution problem,” is related to the level of observable risk in the firm. When observable and unobservable risks are sufficiently positively correlated, increases (decreases) in observable risk generate the incentive for manager-equityholders to increase (decrease) unobservable risk. Thus, credible commitments to hedge observable risk can benefit the firm's manager-equityholders by reducing the incentive to shift risk and the associated agency cost of debt. This provides a positive rationale for hedging diversifiable risk at the firm level.

This paper examines whether futures market data can be used to understand the behavior of real interest rates. Several ways of examining the data indicate that futures market data are not particularly informative about real interest rates. Not only does this evidence cast some doubt on results in previous research that make use of futures market data to draw inferences about real interest rates, but it also indicates that future research on real interest rates may need to turn to a different line of attack.

This paper examines optimal hedging behavior in a market where preferences for current consumption are partly determined by the consumer's past consumption history. The model considers an individual exposed to price risk, who allocates wealth between consumption and futures contracts over a (continuous‐time) finite planning horizon. The speculative component of the hedge ratio is shown to be smaller and the consumption path smoother than in models where preferences are separable over time. Some comparative‐static properties of the hedge ratio are also examined.

This paper develops a theory of capital structure in an international setting with corporate and personal taxes. We generalize the Miller analysis to an international equilibrium characterized by differential international taxation and inflation in otherwise perfect international capital markets. Our analysis highlights the key role that corporate tax arbitrage plays in generating an international capital structure equilibrium, and we set forth a number of mechanisms for tax arbitrage transactions. We close the paper by outlining some implications of our analysis for national differences in capital structure, the International Fisher Effect, and international tax effects on yield differentials.
