We investigate the dynamics of prices, information and expectations in a competitive, noisy, dynamic asset pricing equilibrium model. We show that prices are farther away from (closer to) fundamentals compared with average expectations if and only if traders over- (under-) rely on public...

This paper examines the extent to which individual investors provide liquidity to the stock market, and whether they are compensated for doing so.We show that the ability of aggregate retail order imbalances, contrarian in nature, to predict short-term future returns is significantly enhanced...

We test the hypothesis that individual investors contribute to the idiosyncratic volatility of stock returns because they act as noise traders. To this end, we consider a reform that makes short selling or buying on margin more expensive for retail investors relative to institutions, for a...

Existing literature continues to be unable to offer a convincing explanation for the volatility of the stochastic discount factor in real world data. Our work provides such an explanation. We do not rely on frictions, market incompleteness or transactions costs of any kind. Instead, we modify a...

Fundamental information resembles in many respects a durable good. Hence, the effects of its incorporation into stock prices depend on who is the agent controlling its flow. Similarly to a durable goods monopolist, a monopolistic analyst selling information intertemporally competes against...

In a market with short term agents and heterogeneous information, when liquidity trading displays persistence, prices reflect average expectations about fundamentals and liquidity trading. Informed investors exploit a private learning channel to infer the demand of liquidity traders from the...

We describe a new mechanism that explains the transmission of liquidity shocks from one security to another ("liquidity spillovers"). Dealers use prices of other securities as a source of information. As prices of less liquid securities convey less precise information, a drop in liquidity for...

We investigate whether short sellers are subject to the disposition effect using a novel dataset that allows to identify the weekly closing of short positions. Consistent with the disposition effect, the closing of short sale positions is strongly related to a proxy of Shortsale Capital Gains...

We investigate whether providers of high frequency news analytics affect the stock market. As identification, we exploit a unique experiment based on differences in news event classifications between different product releases of a major provider of news analytics. We document a causal effect of...

The prices of Greek closed-end funds behave similarly to the prices of US funds: they deviate substantially from their net asset values (NAVs); they are more volatile than their NAVs; and they are overly-sensitive to the movements of the domestic stock market index. Furthermore, their premia...
