I develop a new asset pricing theory that bridges two seemingly unrelated pricing effects from separate literatures: (1) the negative relationship between ex-ante return skewness and expected returns and (2) the negative relationship between dispersion in financial analysts' earnings forecasts...

We study the interaction of noisy demand and skewed asset payoffs. In our model, price as a function of quantities is convex in a neighborhood around zero if and only if skewness is positive. The combination of convexity and noise produces the idiosyncratic skewness effect--a documented negative...

We propose a novel and tractable equilibrium model to study how information asymmetry, competition among market makers, and investors' risk aversion affect asset pricing, market illiquidity and welfare. The main innovation is that market makers compete through choosing simultaneously quantities...

Through extending a standard Grossman and Stiglitz (1980) noisy rational expectations economy by a heterogeneous signal structure with signal-specific differences in uncertainty, we show that price momentum as well as reversal are not intrinsically at odds with rational behavior. Differences in...

I present a new model of how ex-ante skewness affects expected asset prices. The price that supports a given short position in a positively- (negatively-) skewed asset is further from (closer to) expected value than is the price that supports a long position of the same magnitude, even in a...

We study the impact of short-sale constraints on market prices and liquidity in imperfectly competitive markets in which market-makers have market power. We show that, with or without information asymmetry, short-sale constraints decrease bid prices, but increase bid-ask spreads and...

We develop a new asset pricing theory that bridges two seemingly unrelated anomalies: (1) the negative relationship between dispersion in financial analysts’ earnings forecasts and expected returns and (2) the negative relationship between ex-ante skewness and expected returns. The results...

We model asset issuance in over-the-counter markets. Investors buy newly issued assets in a primary market and trade existing assets in a secondary market, where both markets are over the counter. We show that the level of asset issuance and its efficiency depend on how investors split the...

A new alternative diffusion model for asset price movements is presented. In contrast to the popular approach of Brownian motion it proposes deterministic diffusion for the modelling of stock price movements. These diffusion processes are a new area of physical research and can be created by the...

We study a rational expectations' competitive equilibrium in a production economy, i.e., a system of prices at which firms' profit maximizing production decisions and individuals' preferred affordable consumption choices equate supply and demand in every market. We derive the equilibrium price...
