Abstract This paper develops a model of active portfolio management in which fund managers may secretly gamble in order to manipulate their reputation and at- tract more funds. We show that such trading strategies may expose investors to severe losses and are more likely to occur when fund managers are impatient, their trading skills are scalable and generate higher pro t per unit of risk. We characterize the optimal contracts that deter this behavior. Our model can ex- plain a number of observed di erences in performance between mutual and hedge fund. In particular, it explains why persistence in returns and net risk-adjusted returns can be higher for hedge funds, and o ers a rationale for the prevalence of high-water mark contracts.

Bubble Cycles

Abstract We develop a simple model that explains episodes on bubbles that occurred in the past Japan and the recent United States. The basic idea is that the self-fulfilling change in the saving rate leads to bubble-induced business cycles with co-movement between bubbles and investment. We have a counter-intuitive implication of the stimulus package of fiscal expansion in the bubbly economy.
