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...

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...

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...

The paper analyses the effects of strategic behaviour by an insider in a price discovery process, akin to an information tâtonnement, in the presence of a competitive informed sector. Such processes are used in the pre-opening period of continuous trading systems in several exchanges. It is...

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 study a general static noisy rational expectations model, where investors have private information about asset payo¤s, 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...

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...

We analyse the effects of insider trading on real investment and welfare, and the consequences of different regulatory policies: a disclose-or-abstain rule, ‘fair’ disclosure, laissez-faire and forbidding insider trades based on ‘precise’ information. We perform the analysis in a model...
