This paper presents a formal theory of reciprocity. Reciprocity means that people reward kind actions and punish unkind ones. The theory takes into account that people evaluate the kindness of an action not only by its consequences but also by the intention underlying this action. The theory...

In this paper we show that a simple model of fairness preferences explains major experimental regularities of common pool resource (CPR) experiments. The evidence indicates that in standard CPR games without communication and without sanctioning possibilities inefficient excess appropriation is...

This chapter presents the theory of international environmental agreements (IEAs). It explains what treaties do (or should do); when and why they succeed or fail; and whether they can be designed better. It focuses on the main questions that the literature on this topic has tried to answer,...

Arms races – enduring rivalries between pairs of hostile powers, which prompt competitive acquisition of military capability – appear to be a pervasive phenomenon. From the past Cold War competition, between the US and the USSR, to present regional antagonisms, such as India and Pakistan,...

The construction of formal models that deal with space observed a huge increase since the late 1980s. As Fujita et al. (1999) stress, the field of regional economics experienced a revival with the emergence of new analytical tools such as the diffusion of imperfect competition models, networks...

Global games of regime change that is, coordination games of incomplete information in which a status quo is abandoned once a sufficiently large fraction of agents attacks it have been used to study crises phenomena such as currency attacks, bank runs, debt crises, and political change. We...
