The diffusion of two competitive, interchangeable, and durable goods is studied under the framework of a spatial game where consumers are distributed on a two-dimensional square lattice and play 3$\times$3 symmetric coordination-like games with their nearest neighbors. There are three...

We analyse the effect of the uncertainty about the fundamentals on the probability of sudden stops of capital flows from a theoretical and empirical perspective. Our model predicts that the probability of crises increases with the uncertainty, ie. the dispersion of private signals about the true...

It is shown that risk-sharing examined in Rothschild and Stiglitz (1976) has a perfect Nash equilibrium, which is unique, incentive-efficient and continuous in all parameters of the economy. Competition in individual markets of a perfectly competitive economy is generally imperfect and allows...

Attempts by governments to stop bubbles by issuing warnings seem unsuccessful. This paper examines the effects of public warnings using a simple model of riding bubbles. We show that public warnings against a bubble can stop it if investors believe that a warning is issued in a definite range of...

When fairly homogeneous taxpayers are affected by common income shocks, a tax agency’s optimal auditing strategy consists of auditing a low-income declarer with a probability that (weakly) increases with the other taxpayers’ declarations. Such policy generates a coordination game among...

This article proposes a reading of the armed conflict from an evolutionary design that takes into account the concept of private protection agencies in the works of Schelling / Nozick / Gambetta. Their aim is to assess the dynamics of conflict and changes from its author's scientific output. A...

I present a model of social learning over an exogenous, directed network that may be readily nested within broader macroeconomic models with dispersed information and combines the attributes that agents (a) act repeatedly and simultaneously; (b) are Bayes-rational; and (c) have strategic...

In their recent work Thomas S. Schelling (2007, 2010), reiterating original arguments about game theory and its applications to social sciences. In particular, game theory helps to explore situations in which agents make decisions interdependent (strategic communication). Schelling's originality...

We analyse the effect of the uncertainty about the fundamentals on the probability of sudden stops of capital flows from a theoretical and empirical perspective.

The impossibility of speculative trade result (Milgrom and Stokey, 1982) provokes the questions why traders care about their private information, if they cannot profit from it and how the aggregate information can then be reflected in REE prices. This paper answers these questions by analyzing a...
