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...

We link a seemingly biased trading behavior to equilibrium asset prices. U.S. equity mutual fund managers tend to sell both their big winners and big losers. This selling pressure pushes down current prices and leads to higher future returns; aggregating across funds, we nd that securities for...

This paper investigates investor disagreement and clientele effects in performance evaluation by developing a measure that considers the best potential clienteles of mutual funds. In an incomplete market under law-of-one-price and no-good-deal conditions, we obtain an upper bound on admissible...

We present a general equilibrium model in which heterogeneous investors choose among bonds, stocks, and an Index Fund holding the market portfolio. We show that, under standard assumptions, an equilibrium exists. We then derive predictions for equilibrium asset prices, investor behavior, and...

The existence of a premium to momentum portfolios, formed by buying recent winners and selling recent losers is widely accepted, although the source of the returns remains controversial. It remains a focus of behavioural finance. We focus on one set of explanations, based on prospect theory,...

This paper proposes a model of asset-market equilibrium with portfolio delegation and optimal fee contracts. Fund managers and investors strategically interact to determine funds' investment profiles, while they share portfolio risk through fee contracts. In equilibrium, their investment...

In the presence of rising concern about climate change that potentially affects risk and return of investors’ portfolio companies, active investors might have dispersed climate risk exposures. We compute mutual fund covariance with market-wide climate change news index and find that high...

We study the equilibrium implications of a multi-asset economy in which asset managers are subject to different benchmarks, and demonstrate how heterogeneous benchmarking generates a mechanism through which fundamental shocks propagate across assets. Fluctuations in asset managers' capital...

Prior theory suggests that time variation in the degree to which leverage constraints bind affects the pricing kernel. We propose a measure for this leverage constraint tightness by inverting the argument that constrained investors tilt their portfolios to riskier assets. We show that the...

This paper tests whether mutual funds on aggregate matter for the equilibrium stock returns due to (i) uncertain fund flows, which directly affect fund size and managers' income; and (ii) time-varying liquidity costs of assets. I find the aggregate shocks to fund flows enter the pricing kernel in...
