The paper analyzes a very stylized model of crises and demonstrates how the degree of strategic complementarity in the actions of investors is a critical determinant of fragility. It is shown how the balance sheet composition of a financial intermediary, parameters of the information structure...

This paper performs a welfare analysis of economies with private information when public information is endogenously generated and agents can condition on noisy public statistics in the rational expectations tradition. We find that equilibrium is not (restricted) efficient even when feasible...

We investigate the dynamic of prices, information and expectations in a competitive, noisy, dynamic asset pricing equilibrium model. We look at the bias of prices as estimators of fundamental value in relation to traders' average expectations and note that prices are more (less) biased than...

Games of strategic complementarities are those in which any player increases his action in response to an increase in the level of actions of rivals. This paper provides an introduction to the theory of games of strategic complementarities, considers Bayesian games, and provides an application...

We analyze a divisible good uniform-price auction that features two groups each with a finite number of identical bidders. Equilibrium is unique, and the relative market power of a group increases with the precision of its private information but declines with its transaction costs. In line with...

We show that limited dealer participation in the market, coupled with an informational friction resulting from high frequency trading, can induce demand for liquidity to be upward sloping and strategic complementarities in traders' liquidity consumption decisions: traders demand more liquidity...

This paper considers cost-reducing R&D investment with spillovers in a Cournot oligopoly with overlapping ownership. We show that overlapping ownership leads to internalization of rivals profits by firms and find that, for demand not too convex, increases in overlapping ownership increase...

This paper performs a welfare analysis of markets with private information in which agents can condition on noisy prices in the rational expectations tradition. Price-contingent strategies introduce two externalities in the use of private information: a payoff (pecuniary) externality related to...

We consider a two-period market with persistent liquidity trading and risk averse privately informed investors who have a one period horizon. With persistence, prices reflect average expectations about fundamentals and liquidity trading. Informed investors engage in "retrospective" learning to...

We consider a spatial model of bank competition to study how the diffusion of information technology affects competition in the lending market, stability of the banking sector, and social welfare. We find that the effects of an improvement in information technology depend on whether or not it...
