In currency exchange markets, there is a conflict between individual decisions and the socially optimal solution. Whereas agents have a coordination motive to take the same position, at the social level effective market coordination per se is not socially valuable, and the central bank aims at...

We examine speculative attacks in a controlled laboratory environment featuring continuous time, size asymmetries, and varying amounts of public information. Attacks succeeded in 233 of 344 possible cases. When speculators have symmetric size and access to information: (a) weaker fundamentals...

We interpret the Open Method of Coordination (OMC), recently adopted by the EU as a mode of governance in the area of social policy and other fields, as an imitative learning dynamics of the type considered in evolutionary game theory. The best-practise feature and the iterative design of the...

Institutions are important for proper economic performance, but are replaceable by trust or other social norms. We show that when proper institutions and trust are missing, integrity of the individuals can replace them. We construct a model of a transactions-based economy with contracts...

Rather than about absolute payoffs, governments in fiscal competition often seem to care about their performance relative to other governments. Moreover, they often appear to mimic policies observed elsewhere. We study such behaviour in a tax competition game with mobile capital à la...

I offer a selective review of discounting and climate policy. Analytic and numerical models show that different assumptions greatly change the degree to which decisions about climate policy depend on the discount rate. I discuss a claim that standard models exaggerate the current generation’s...

Cultural and institutional differences among nations may result in differences in the ratios of marginal costs of goods in autarchy and thus be the basis of specialization and comparative advantage, as long as these differences are not eliminated by trade. We provide an evolutionary model of...

This paper introduces two ideas, emotional state dependent utility components (ESDUCs), and evolutionary perfect Bayesian equilibrium (EPBE). Using a simple extensive form game, we illustrate the efficiency-enhancing role of a powerful ESDUC, the vengeance motive. Incorporating behavioral noise...

Over the past two decades, financial market crises with similar features have occurred in different regions of the world. Unstable cross-market linkages during a crisis are referred to asfinancial contagion. We simulate crisis transmission in the context of a model of market participants...
