Why have Israel and the Palestinians failed to implement a "land for peace" solution, along the lines of the Oslo Accords? This paper studies the application of game theory to this question. I show that existing models of the conflict largely rely on unrealistic assumptions about what the main...

In international relations, short-run incentives for non-cooperation often dominate. Yet, (external) institutions for enforcing cooperation are hampered by national sovereignty, supposedly strengthening the role of selfenforcing mechanisms. This paper examines their scope with a focus on...

A multi-stage model on the course of war is presented: Individual battles are modeled as private value all-pay auctions with asymmetric combatants of two opposing teams. These auctions are placed within a multi-stage framework with a tug-of-war structure. Such framing provides a microfounded...

This paper analyzes a tug of war contest between two teams. In each round of the tug of war a pair of agents from the opposing teams competes in a private value all-pay auction with asymmetric type distributions and effort effectiveness. Whichever team arrives fi rst at a given lead in terms of...

We study the 420 US drone strikes in Pakistan from 2006-2016, isolating causal effects on terrorism, anti-US sentiment, and radicalization via an instrumental variable strategy based on wind. Drone strikes are suggested to encourage terrorism in Pakistan, bearing responsibility for 16 percent of...

I propose a simple model of signed network formation, where agents make friends to extract payoffs from weaker enemies. The model thereby accounts for the interplay between friendship and alliance on one hand and enmity and antagonism on the other. Nash equilibrium configurations are such that...

Recent changes in the security environment of Eastern Europe and the South Caucasus have been reshaping the strategies of the six small countries in the proximity of both the EU and Russia. Their attempts to take upon themselves their Soviet heritage and their sensitive geographical position...

We analyze how trade openness matters for interstate conflict over productive resources. Our analysis features a terms-of-trade channel that makes security policies trade-regime dependent. Specifically, trade between two adversaries reduces each one’s incentive to arm given the opponent’s...
