Abstract
Wars of conquest and wars of independence are characterized by an asymme-try in the payoff structure: The production of one party constitutes the winners prize, while the other partys production is not contested. We present and solve a model of warfare that nests this asymmetric payoff structure as well as the standard symmetric payoff structure. We find that both parties choose lower fighting efforts in asymmetric wars, but that the difference is smaller for the party whose production constitutes the prize. We further show that this party prefers fightingan asymmetric war if its resource endowment is relatively large.
