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...

Three concepts: stochastic discount factors, multi-beta pricing and mean-variance efficiency, are at the core of modern empirical asset pricing. This chapter reviews these paradigms and the relations among them, concentrating on conditional asset-pricing models where lagged variables serve as...

Large-Scale Asset Purchases can impact the price of securities directly, when securities are targeted by the central bank, or indirectly through portfolio re-balancing of private investors. We quantify both the direct and the portfolio re-balancing impact, emphasizing the role of investor...

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...

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...

In this paper, we tackle the Beta anomaly, namely the fact that high-Beta assets tend to be associated with lower risk-adjusted returns than low-Beta assets, and connect it to mutual funds' expectations. We present a model with two types of investors, mutual funds and hedge funds, with...

Open-end mutual funds have grown to become a key player in the corporate bond market. They invest in illiquid bonds but provide liquid claims to shareholders. Does such liquidity transformation introduce fragility to the corporate bond market? To address this question, we create a novel measure...
