We model conflict using an inter-group Tullock contest, and measure its effects upon cooperation using a multi …-level public good game. We demonstrate that conflict increases cooperation within groups, while decreasing cooperation between …

Results suggest that external interventions, when effective in reducing current … conflict and protecting weaker groups, may end up sowing the seeds of greater future conflict. …

We introduce three variations of the Hirshleifer-Skaperdas conflict game to study experimentally the effects of post-conflict … altogether, often after substantial initial conflict. To attain peace, players must first engage in costly signaling by making …

We also identify conditions under which their impact will be both conflict-augmenting and … feedback loops linking ethnic conflict and natural resource degradation in developing country contexts. …

This paper models an opposition group's choice between peace, terrorism, and open conflict …. Terrorism emerges if executive constraints are intermediate and rents are sizeable.
