November 2006The Economics of Conflicts of Interest in Financial Institutions
with Rene M. Stulz: w12695
A conflict of interest exists when a party to a transaction could potentially make a gain from taking actions that are detrimental to the other party in the transaction. This paper examines the economics of conflicts of interest in financial institutions and reviews the growing empirical literature (mostly focused on analysts) on the economic implications of these conflicts. Economic analysis shows that, although conflicts of interest are omnipresent when contracting is costly and parties are imperfectly informed, there are important factors that mitigate their impact and, strikingly, it is possible for customers of financial institutions to benefit from the existence of such conflicts. The empirical literature reaches conclusions that differ across types of conflicts of interest, but over...

July 2001The Impact of Employee Stock Options on the Evolution of Compensation in the 1990s
with Joseph Tracy: w8353
Between 1995 and 1998, actual growth in nominal compensation per hour (CPH) accelerated from approximately 2 percent to 5 percent. Yet as labor markets continued to tighten in 1999, the growth in CPH paradoxically slowed. In this article, we attempt to solve this aggregate wage puzzle by exploring whether changes in pay structure - specifically, the increased use of employee stock options - can account for the behavior of CPH in the late 1990s. CPH reflects employee stock options on the date they are realized rather than on the date they are granted. When we recalculate CPH growth to reflect the value of current stock options when they are granted - rather than their value when they are realized - we find that our adjusted CPH measure accelerated in each year from 1995 to 1999.
