The present paper examines the stability of self-enforcing International Environmental Agreements (IEAs) among heterogeneous countries in a twostage emission game. In the first stage each country decides whether or not to join the agreement, while in the second stage the quantity of emissions is...

In this paper we report results from a comparison of numerically calibrated game theoretic integrated assessment models that explore stability and performance of international coalitions for climate change mitigation. Specifically, by means of this ensemble of models we are able to identify...

The evolution of large-scale cooperation among genetic strangers is a fundamental unanswered question in the social sciences. Behavioral economics has persuasively shown that so called "strong reciprocity" plays a key role in accounting for the endogenous enforcement of cooperation. Insofar as...

This paper examines characteristics of cooperative behavior in a repeated, n-person, continuous action generalization of a Prisoner's Dilemma game. When time preferences are heterogeneous and bounded away from one, how "much" cooperation can be achieved by an ongoing group? How does group...

This paper studies the incentives for international cooperation if (some) countries prefer a more equitable distribution of per capita emission levels. The impact of such an equity preference is analyzed first for a bilateral, and then for a multilateral environmental problem. We show that -...

In this paper, we tackle the dilemma of pruning versus proliferation in a vertically differentiated oligopoly under the assumption that some firms collude and control both the range of variants for sale and their corresponding prices, likewise a multiproduct firm. We analyse whether pruning...

This paper analyzes price collusion in a repeated game with two submarkets; a standard and a premium quality segment. Within this setting, we study four types of price-fixing agreement: (i) a segment-wide cartel in the premium submarket only, (ii) a segment-wide cartel in the standard submarket...
