Fund Flows and Asset Prices: A Baseline Model

Dimitri Vayanos and Paul Woolley ()

FMG Discussion Papers from Financial Markets Group

Abstract: We study flows between investment funds and their effects on asset prices in a simple two period version of Vayanos and Woolley (2010, VW). As in VW, flows cause assets to commove in ways unrelated to fundamentals, affect assets with high idiosyncratic risk the most, and raise the expected returns of funds experiencing outflows. We sketch how adding periods can generate other results of VW such as momentum, reversal, amplification, and commercial-risk management. We also extend the VW framework to study how index redefinitions affect the price level and the extent of comovement.
