We propose a novel measure of arbitrage activity to examine whether arbitrageurs can have a destabilizing effect in the stock market. We apply our...

This paper finds that fund herding, defined as the tendency of a mutual fund to follow past aggregate institutional trades, is an important predictor...

We explore a new mechanism through which investors take correlated shortcuts. Specifically, we exploit a regulatory provision governing firm...

The conventional view of market timing suggests an unambiguous, negative relation between equity misvaluation and the equity share in new issues—that...

In this paper we survey the theoretical and empirical literature on market liquidity. We organize both literatures around three basic questions: (a)...

We analyze how asymmetric information and imperfect competition affect liquidity and asset prices. Our model has three periods: agents are identical...

We study dynamic general equilibrium in one-tree and two-trees Lucas economies with one consumption good and two CRRA investors with heterogeneous...

We propose a new theory of suboptimal risk-taking based on contractual externalities. We examine an industry with a continuum of firms. Each firm’s...

We study a broad class of asset pricing models in which the stochastic discount factor (SDF) can be factorized into an observable component and a...

An important recent theoretical literature argues that the threat of exit can represent an effective form of governance when the blockholder is a...

Mutual funds hold large blocks of shares in many major corporations. Practitioners and regulators alike have been concerned that mutual funds use...

We analyze credit default swap settlement auctions theoretically and evaluate them empirically. In our theoretical analysis, we show that the current...

We exploit a novel setting in which the same piece of information affects two sets of firms: one set of firms requires straightforward processing to...

Despite much work on hedging in incomplete markets, the literature still lacks tractable dynamic hedges in plausible environments. In this article, we...

We estimate structurally a model of the term structure of interest rates that is consistent with no arbitrage but allows for demand pressures. The...
