In the Sixties, the qualified stock option was the predominant form of long-term incentive compensation contract for major industrial firms in the U.S. In the early Seventies these same firms replaced their tax-qualified stock option plans with non-qualified sttock options and later modified these plans to include a variety of new contingent compensation arrangements, some of which were based on accounting numbers instead of stock prices. This paper develops the hypothesis that tax considerations play an important role in explaining the form of compensation contracts. The pattern and timing of changes in the compensation plans of the top 100 industrial firms provides evidence consistent with the tax hypothesis.

This article integrates strategic product market analysis with price-taking asset pricing theory. We demonstrate that a firm's market power can lead to scale-dependent and potentially infinite required returns. Scale dependency, which we relate to risk spillovers between expansionary and existing cash flows, reflects the divergence of incremental from existing required returns. The firm-specific nature of risk spillovers potentially destroys the concept of a common industry "risk class". Our analysis raises important questions regarding the validity of widely used "comparables" methods for determining risk-adjusted discount rates.

This paper provides empirical evidence that takeovers can facilitate the efficient redeployment of assets of bankrupt firms. Bidders for bankrupt firms are generally in related industries and often have some prior relationship to the target, suggesting they are well informed with respect to both the value and best use of the target's assets. For a sample of 55 acquisitions in Chapter 11, we find that firms merged with bankrupt targets show significant improvements in operating performance, while matching non-bankrupt transactions show no significant improvement. We also find positive and significant abnormal stock returns for the bidder and bankrupt target at the announcement of the acquisition.Journal of Economic LiteratureClassification Numbers: G33, G34.

Military assignment mechanisms provide a unique opportunity to estimate the impact of high-performing mentors on job advancement of their subordinates. Combining US Army administrative data with officer evaluation reports, we find that high-performing mentors positively affect early junior officer promotion and that early promotion probabilities rise as the duration of the high-quality mentorship increases. These effects are largest for high-ability protégés. Junior officers who were exposed to multiple high-performing mentors did not experience an additional increase in promotion rates.
