Using a game-theoretic model of criminal procedure, we investigate relative merits and demerits between discretionary and mandatory prosecution. The game illustrates a prosecutor's dilemma associated with his two tasks: evidence production and case screening. Discretionary prosecution makes use...

This study proposes a dynamic model of rebellion, where three players individually decide to challenge their common adversary. It is formally demonstrated that the pattern of rebellion is determined endogenously, depending on the challengers' resolve and strength. In other words, a stronger...

Formal models of war termination have been developed along two major approaches: in one, war is interpreted as a series of battles, where belligerents exchange denial campaigns; in the other, war is illustrated as a process of bargaining with mutual punishments. In integrating these two...

We explore a defender's prewar allocation of military resources between denial and punishment strategies for deterrence. While denial disproportionately raises the probability to countervail aggression by disrupting military forces ("guns"), punishment proportionately raises costs on the...

How do belligerents choose and change their military strategies during war? How do these strategies shape war? To address these questions, we develop a random-walk model of war, where two belligerents fight over "forts" across periods. The random walk represents a battlefront, which moves as the...

Using costly-process models of war with democratic citizens and soldiers, this article explores two contrasting claims on the negative association between the probability of democratic victory and the duration of war. As a claim holds, democracies are not militarily disadvantageous in long wars....

While the theoretical literature maintains that strategic coordination is one of the keys to successful rebellion, anti-governmental campaigns are not necessarily synchronized across rebel groups in observed civil wars. To resolve this discrepancy, we develop a dynamic and spatial model of...
