Some investors (insiders) observe prices in real-time whereas other investors (outsiders) observe prices with a delay. As prices are informative about the asset payoff, insiders get a strictly larger expected utility than outsiders. Yet, information acquisition by one investor exerts a negative...

I analyze a multi-asset market under two trading mechanisms. In the first (the unrestricted system), traders' demand for each asset depends on all equilibrium prices and prices reflect the information contained in all order flows; in the second (the restricted system), traders' demand depends on...

This paper shows that information effects per se are not responsible for the Giffen goods anomaly affecting traders' demands in multi asset noisy, rational expectations equilibrium markets. The role that information plays in traders' strategies also matters. In a market with risk averse,...

We analyze the effect that real-time domestic and foreign news about fundamentals have on the correlation of stock returns of a small open economy, Portugal, and a large open economy, the U.S. We also study the role of public and private information in the price formation process in the U.S. and...

This paper studies international equity markets when some investors have private information that is valuable for trading in many countries simultaneously. We use a dynamic model of equity trading to show that 'global' private information helps understand US investors’ trading behaviour and...

This paper provides a dynamic rational expectations equilibrium model in which investors have heterogeneous information and investment opportunities. Informed investors privately receive advance information that is useful for predicting future earnings, but is unrelated to current earnings. This...

We present a model of equity trading with informed and uninformed investors where informed investors act upon firm-specific private information and marketwide private information. The model is used to structurally identify the component of order flow that is due to marketwide private...

This paper reconsiders the role of foreign investors in developed country equity markets. It presents a quantitative model of trading that is built around two new assumptions about investor sophistication: (i) both the foreign and domestic populations contain investors with superior information...

Aggregate stock market returns display negative skewness. Firm-level stock returns display positive skewness. The large literature that tries to explain the first stylized fact ignores the second. This paper provides a unified theory that reconciles the two facts. I build a stationary asset...

This paper analyzes the asset pricing implications of periodic cash payouts within the context of a stationary rational expectations model with heterogeneous investors. The periodicity of cash payouts provides a natural motivation for time-varying conditional volatility in stock returns. I show...
