We experimentally test the social motives behind individual participation in intergroup conflict by manipulating the framing and symmetry of conflict. We find that behavior in conflict depends on whether one is harmed by actions perpetrated by the out-group, but not on one’s own influence on...

Solar geoengineering has received increasing attention as an option to temporarily stabilize global temperatures. A key concern surrounding these technologies is that heterogeneous preferences over the optimal amount of cooling combined with low deployment costs may allow the country with the...

In this paper, we show that a concept of aggregation can hold in large network games with linear best replies. Breaking up large networks into smaller subnetworks, which can be replaced by representative players, leads to a coarse-grained description of strategic interactions. This method of...

Motivated by recent examples of collective effort on the war on terror, we examine the incentives that retaliation may produce for the endogenous formation of an international counterterror coalition. We show that there are quite reasonable circumstances under which any nation that is a target...

This paper is the first systematic examination of (counter)terrorism dynamic games with two types of externalities: temporal and spatial. We consider two types of non-cooperative behavior; one in which national authorities are sensitive with respect to the spatial spillovers of counterterror...

Previous research shows that collective action to avoid a catastrophic threshold, such as a climate "tipping point", is unaffected by uncertainty about the impact of crossing the threshold but that collective action collapses if the location of the threshold is uncertain. Theory suggests that...

Resettlement is one means of assisting refugees to regain self-reliant living with- out constant fear. The global total of resettled refugees has remained fractional relative to the need. To contribute to the ongoing effort to increase resettlement, we consider self-enforceable sharing of full...

First, the paper lays out the fun-damental assumptions underlying the game theoretical analysis of international environmental problems. Second it summarises important findings which help to explain the difficulties of co-operation and discusses remedies. Chapter 3 looks at measures to avoid...

Many researchers have found game theory a useful method for analyzing internationalenvironmental problems. However, game theory has been criticized for being too theoretical,abstracting from too many practical problems and being based on very specific assumptions.This article tries to qualify...
