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...

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...

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...

A Large-Market Rational Expectations Equilibrium Model

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...

Monetary Policy with Diverse Private Expectations

Kurz, Mordecai; Motolese, Maurizio; Piccillo, Giulia; … - CESifo - 2015

We study the impact of diverse beliefs on conduct of monetary policy. We use a New Keynesian Model solved with a quadratic approximation. Aggregation renders the belief distribution an aggregate state variable. Diverse expectations change standard results about a smooth trade-off between...
