We consider a setting where investors receive private signals about cash flows as well as their betas. We obtain a closed-form solution for the case where informed agents are risk neutral and the market maker is risk averse. Market liquidity is non-linear and non-monotonic (under reasonable...

We analyze a model with information asymmetry where owning stock confers direct utility, in addition to impacting wealth. In contrast to settings based on wealth considerations alone, expected stock prices deviate from expected fundamentals even when assets are in zero net supply. Stocks that...

Presentation Slides for "Overconfidence, Arbitrage, and Equilibrium Asset Pricing" This paper offers a model in which asset prices reflect both covariance risk and misperceptions of firmsapos prospects, and in which arbitrageurs trade against mispricing. In equilibrium, expected returns are...

Movements in expected returns (ER) can cause a bias in measured autocorrelations, and the resulting spurious component is positive for infrequent regime shifts. We demonstrate this point analytically and investigate its empirical prevalence. In a key contribution, we use shifts in ex ante ER...

This paper studies cross-sectional variations in stock trading activity for a comprehensive sample of NYSE/AMEX and Nasdaq stocks over a period of thirty-six years. Our theoretical framework indicates that trading activity depends on the extent of liquidity trading, the mass of informed agents,...

We study the consumption-investment problem of an agent with constant relative risk aversion (CRRA) preferences who possesses private information about the future prospects of a stock. We examine the value of the information to the agent by comparing the utility equivalent with and without the...

Little is known about the joint dynamics of volume across the various contingent claims on the equity market. We study the time-series of trading activity in the cash S&P 500 index and its derivatives (options, the legacy and E-mini futures contracts, and the ETF), and consider their dynamic...

We explore the premise that the degree of market efficiency changes dynamically as investment funds face time-varying funding constraints to arbitrage capital. We show that the returns to a composite long-short hedge strategy that encompasses relative value, momentum, short-run reversals, and...

We estimate buy- and sell-order illiquidity measures (lambdas) for a comprehensive sample of NYSE stocks. We show that sell-order liquidity is priced more strongly than buy-order liquidity in the cross-section of equity returns. Indeed, our analysis indicates that the liquidity premium in...

Feedback from stock prices to cash flows occurs because information revealed by firms' stock prices influences the actions of competitors. We explore the implications of feedback within a noisy rational expectations setting with publicly listed and private firms. In our setting, stock prices are...
