In a financial market where agents trade for short-term profit and where news can increase the uncertainty of the public belief, there are strategic complementarities in the acquisition of private information and if the cost of information is sufficient small, a continuum of equilibrium...

By using an extensive panel data set of Italian firms, we show empirically that the fraction of firms that engage in a lumpy investment follows a non-normal, double-exponential distribution across region-year. We propose a simple sectoral model that generates the double-exponential distribution...

We study oligopoly price competition between multiproduct firms---firms whose products interact in the profit function. Specifically, we focus on the impact of intrafirm product interactions on the level of equilibrium profits. This impact may be decomposed in two different ways: (a) a direct...

We accomplish two tasks to characterize aggregate price stickiness in this paper. First, we endogenize beta , the fraction of the firms keeping their price unchanged following a money supply shock in the near-rationality model (Akerlof and Yellen, 1985) by introducing a distribution of...

The beauty-contest framework of Morris and Shin (2002) is extended to allow sub-groups within the population of agents to differ in the quality (i.e. precision) of their private information. We discuss the inefficiency of the resulting model's equilibrium, and assess the relative effectiveness...

Do public policy signals improve the alignment of market outcomes with economic fundamentals? Existing work contends that, when individual players have an incentive to coordinate their actions, public policy signals could steer these actions away from the fundamentals. We argue that such a...

We construct a dynamic theory of civil conflict hinging on inter-ethnic trust and trade. The model economy is inhabitated by two ethnic groups. Inter-ethnic trade requires imperfectly observed bilateral investments and one group has to form beliefs on the average propensity to trade of the other...

In this paper we review the state of the art of Games with Strategic Complementarities (GSC), which are fundamental tools in modern Industrial Organization. The originality of the paper lies in the way the material is presented. Indeed, the mathematical aspects of GSC are complex and scattered...

In two-player games with negative (positive) spillovers it is well-known that symmetric agents both overact (underact) at the Nash equilibria. We show that for heterogeneous agents this rule of thumb has to be amended if the game features strategic substitutability.
