Public and Private Learning from Prices, Strategic Substitutability and Complementarity, and Equilibrium Multiplicity
Manzano, Carolina; Vives, Xavier - CESifo - 2010
We study a general static noisy rational expectations model, where investors have private information about asset payoffs, with common and private components, and about their own exposure to an aggregate risk factor, and derive conditions for existence and uniqueness (or multiplicity) of...

Vives, Xavier - CESifo - 2011
This paper presents a market with asymmetric information where a privately revealing equilibrium obtains in a competitive framework and where incentives to acquire information are preserved. The equilibrium is efficient, and the paradoxes associated with fully revealing rational expectations...

Asset Auctions, Information, and Liquidity
Vives, Xavier - CESifo - 2010
A model is presented of a uniform price auction where bidders compete in demand schedules; the model allows for common and private values in the absence of exogenous noise. It is shown how private information yields more market power than the levels seen with full information. Results obtained...

Strategic Supply Function Competition with Private Information
Vives, Xavier - CESifo - 2009
A finite number of sellers (n) compete in schedules to supply an elastic demand. The costs of the sellers have uncertain common and private value components and there is no exogenous noise in the system. A Bayesian supply function equilibrium is characterized; the equilibrium is privately...

The Existence of Informationally Efficient Markets When Individuals Are Rational
Muendler, Marc-Andreas - CESifo - 2004
A rational-expectations equilibrium with positive demand for financial information does exist under fully revealing asset price - contrary to a wide-held conjecture. Generalizing the common additive signal-return model with CARA utility to the family of distributions with moment generating...

Predictability of Asset Returns and the Efficient Market Hypothesis
Pesaran, M. Hashem - CESifo - 2010
This paper is concerned with empirical and theoretical basis of the Efficient Market Hypothesis (EMH). The paper begins with an overview of the statistical properties of asset returns at different frequencies (daily, weekly and monthly), and considers the evidence on return predictability, risk...

Dynamic Trading and Asset Prices: Keynes vs. Hayek
Cespa, Giovanni; Vives, Xavier - CESifo - 2009
We investigate the dynamics of prices, information and expectations in a competitive, noisy, dynamic asset pricing equilibrium model with long-term investors. We argue that the fact that prices can score worse or better than consensus opinion in predicting the fundamentals is a product of...
