We study intraday market intermediation in an electronic market before and during a period of large and temporary selling pressure. On May 6, 2010, U.S. financial markets experienced a systemic intraday event - the Flash Crash - where a large automated selling program was rapidly executed in the...

We solve a liquidation problem for an agent with preferences consistent with the prospect theory of Kahneman and Tversky (1978). We find that the agent is willing to hold a risky project with a relatively inferior Sharpe ratio if the project is currently making losses, and intends to liquidate...

This paper derives and estimates an equilibrium model of stock price behavior in which exogenous quot;noise tradersquot; interact with risk-averse quot;smart moneyquot; investors. The model assumes that changes in exponentially detrended dividends and prices are normally distributed, and that...

We propose a new market design for trading financial assets. The design combines three elements: (1) Orders are downward-sloping linear demand curves with quantities expressed as flows; (2) Markets clear in discrete time using uniform-price batch auctions; (3) Traders may submit orders for...

This paper combines dimensional analysis, leverage neutrality, and a principle of market microstructure invariance to derive scaling laws expressing transaction costs functions, bid-ask spreads, bet sizes, number of bets, and other financial variables in terms of dollar trading volume and...

We derive invariance relationships for a dynamic infinite-horizon model of market microstructure with risk-neutral informed trading,noise trading,marketmaking, and endogenous production of information. Invariance relationships for bet sizes and transaction costs are obtained under the assumption...

We describe a symmetric continuous-time model of trading among relatively overconfident, oligopolistic informed traders with exponential utility. Traders agree to disagree about the precisions of their continuous flows of Gaussian private information. The price depends on a trader's inventory...

Modest differences in higher-order beliefs may have large price effects. We generalize a standard rational expectations equilibrium model with different information by allowing differences in higher-order beliefs. Investors have possibly different dogmatic beliefs about the mean, different...

We derive invariance relationships in a dynamic, infinite-horizon, equilibrium model of adverse selection with risk-neutral informed traders, noise traders, market makers, and with endogenous information production. The model solution depends on two state variables: stock price and...

We study return predictability using a model of speculative trading among relatively overconfident competitive traders who agree to disagree about the precision of their private information. Although traders apply Bayes Law consistently, returns are predictable. In addition to trading on...
