We use novel data on individual activity in a sports betting market to study the effect of past performance sequences on individual behavior in a real market. The revelation of fundamental values in this market enables us to disentangle whether behavior is caused by sentiment or by superior...

We study empirically whether short selling deters the incorporation of positive information. We find a sizeable reduction of positive information impounding before earnings announcements for stocks more exposed to short selling. The price pressure from short selling cannot explain this effect....

We develop a two-period general equilibrium model of portfolio delegation with competitive, differentially skilled managers and convex compensation contracts. We show that convex incentives lead to significant equilibrium mispricing, but reduce price volatility. In particular, price...

I model a market in which a trader with superior information about an asset is subject to careful scrutiny by another agent who immediately observes the trading decisions of the informed agent with some noise and engages in (klepto)parasitic behavior by imicking the informed trader and trading...

On October 26, 2008, Porsche announced a largely unexpected domination plan for Volkswagen. The resulting short squeeze in Volkswagen's stock briefly made it the most valuable listed company in the world. We argue that this was a manipulation designed to save Porsche from insolvency and the...

We model a two-tiered market structure in which an investor can trade an asset on a trading platform with a set of dealers who in turn have access to an interdealer market. The investor's order is informative about the asset's payoff and dealers who were contacted by the investor use this...

We explore a novel survey on responsible investing by institutional investors around the world and match it to archival data on their equity portfolio holdings. We document that institutions that publicly commit to responsible investing exhibit better environmental, social, and governance (ESG)...

We propose a dynamic Rational Expectations (RE) bubble model of prices with the intention to exploit it for and evaluate it on optimal investment strategies. Our bubble model is defined as a geometric Brownian motion combined with separate crash (and rally) discrete jump distributions associated...

This article analyzes the effect of liquidity risk on the performance of various hedge fund portfolio strategies. Similarly to Avramov et al. (2007), we find that, before accounting for the effect of liquidity risk, hedge fund portfolios that incorporate predictability in managerial skills...

We show that mutual funds compete for climate-conscious investment flows. In April 2018, Morningstar introduced a climate-focused label for mutual funds. The release of the "Low Carbon Designation" induced reactions on both the demand and supply sides of the market. First, investors flocked to...
