We study repurchase options (repo contracts) in a competitive asset market with asymmetric information. Gains from trade emerge from a liquidity need, but private information about asset quality prevents the full realization of trade. We obtain a unique equilibrium, which features a pooling repo...

I study a model of blockholder short-termism, where each blockholder (e.g., activist shareholder) has a stake in a different firm and can sell before the impact of his actions on firm value is realized. I find that the existence of value-destroying blockholders can increase average firm value,...

This article analyzes the manifold situations in which the efficient-market hypothesis (EMH) has influenced — or has failed to influence — federal securities regulation and state corporate law, and the prospective roles for the EMH in these contexts. In federal securities regulation, the EMH...

This paper analyzes the informational efficiency of OTC currency options on the Czech koruna and the Polish zloty correcting for the volatility risk premium and errors-in-variable problems, using state-of-the-art techniques (Chernov 2001). It finds that these markets are more efficient than...

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...

Despite negative experiences with auctioning off subsidies for renewable energy in some countries, tenders are increasingly used today. We develop a reverse auction which accounts for particularities of intermittent renewable energy sources. Determining the quantity, demanded by the regulator,...

We find hedge funds that have higher return covariation with a disaster concern index, which we construct using out-of-the-money puts on sector indices, earn significantly higher returns. These funds have better skills in exploiting the market's ex ante rare disaster concerns (SED) that are not...

Riley (1979)'s reactive equilibrium concept addresses problems of equilibrium existence in competitive markets with adverse selection. The game-theoretic interpretation of the reactive equilibrium concept in Engers and Fernandez (1987) yields the Rothschild-Stiglitz (1976)/Riley (1979)...
