|June 2020||To Pool or Not to Pool? Security Design in OTC Markets|
with , : w27361
We study security issuers' decision whether to pool assets when facing counterparties endowed with market power, as is common in over-the-counter markets. Unlike in competitive markets, pooling assets may be suboptimal in the presence of market power - both privately and socially - in particular, when the potential gains from trade are large. In these cases, pooling assets reduces the elasticity of trade volume in the relevant part of the payoff distribution, exacerbating inefficient rationing associated with the exercise of market power. Our results shed light on recently observed time-variation in the prevalence of pooling in financial markets.
|June 2009||Is Investor Rationality Time Varying? Evidence from the Mutual Fund Industry|
with , , : w15038
We provide new empirical evidence suggesting that the marginal investor in mutual funds behaves differently across market conditions. If the marginal investor allocates capital across mutual funds rationally, then the relative performance of funds should be unpredictable. We find however that relative fund performance is predictable after periods of high market returns but not after periods of low market returns. The asymmetric predictability in performance we document cannot be explained by time-varying differences in transaction costs or style exposures between funds, or by sample selection. Consistent with the hypothesis that the asymmetric predictability in performance may be driven by unsophisticated investors' mistakes when allocating capital, we document that performance predictabil...
