We study the macroeconomic consequences of financial market concentration in a complete markets economy with production. We propose a theory in which differences in preferences, productivity, and risk exposure generate gains from trade, but these gains are not fully realized because some large...

During the 15 years prior to the global financial crisis the volume of securitized assets transacted in the US grew substantially, reflecting a change in the nature of the financial intermediation process. Together with increased securitization of assets, financial entities, who participate more...

Hedge fund flows chase alpha, yet they also follow returns attributable to traditional and exotic risk exposures. Investors appear more cognizant of exotic risks over time, with flows increasing their relative emphasis on returns from exotic betas in recent years. Investors also discriminate...

This paper studies the effect of new fund flows on investment behavior and the resulting equilibrium price of risk. The Small Fund Industry model shows equilibria with overinvestment in unprofitable and underinvestment in profitable investment opportunities. The Large Fund Industry model derives...

Recent evidence indicates that market model alphas are stronger predictors of mutual fund flows than alphas with other models. Berk and van Binsbergen (2016) claim that this evidence indicates CAPM is the best asset pricing model but Barber, Huang and Odean (2016) (BHO) claim it is evidence...

CAPM alpha explains hedge fund flows better than alphas from more sophisticated models. This suggests that investors pool together sophisticated model alpha with returns from exposures to traditional (except for the market) and exotic risks. We decompose performance into traditional and exotic...

Mutual funds seek alpha, but coskewness is also an important performance attribute. Alpha and coskewness relative to the market are negatively correlated in theory, so funds may generate undesirable coskewness in the pursuit of alpha. Empirically, the tradeoff exists for mutual funds and is...

Is alpha a property of the hedge fund or the individual hedge fund manager? By means of panel regressions on a novel data set, identifying the work histories of individual hedge fund managers, I show that there exist significant managerial fixed effects in abnormal returns. A change in a hedge...

We find evidence for the beta anomaly in mutual fund performance. This anomaly is not accounted for in the standard four-factor framework, nor by the addition of a BAB factor to the benchmark model. We identify the active component of alpha (i.e., active alpha) not attributable to the passive...
