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...

This paper analyzes the welfare implications of information aggregation in a security-trading model where traders have both idiosyncratic endowment risk and asymmetric information about security payoffs. In the model a large market can be welfare-reducing --- i.e., the optimal market size is...

Concerns about anti-competitive effects of proprietary data collection have motivated recent European data portability laws. We investigate such concerns and search for evidence of direct benefits of data collection in the context of Pay How You Drive (PHYD) auto insurance, which offers tailored...

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...

By using general information structures and precision criteria based on the dispersion of conditional expectations, we study how oligopolists’ information acquisition decisions may change the effects of information sharing on the consumer surplus. Sharing information about individual cost...

A Bayesian supply function equilibrium is characterized in a market where firms have private information about their uncertain costs. It is found that with supply function competition, and in contrast to Bayesian Cournot competition, competitiveness is affected by the parameters of the...

The paper derives clear-cut and robust conclusions on the effects of sharing firm-specific information in general linear oligopoly. In Cournot (Bertrand) oligopoly, revealing (concealing) firm-specific cost information is the dominant strategy for each firm. In both competition modes firms have...

This paper empirically studies the behavior of university library and journal publishers in the academic journal market. Library demand for academic journals is estimated. Also this paper studies how nonprofit publishers price their journals and predicts prices of commercial journals if they...

New vehicle feebate programs encourage improved fleet-wide vehicle fuel efficiency; yet analyses of these policies have been limited to ad hoc proposals. In this paper, we exploit an extensive, multi-year dataset which includes more than 16 million observations to evaluate the welfare...
