Economics of intellectual property rights in the international arena.

Many issues relating to the protection of intellectual property are economic in nature. This article applies economic analysis to several of those issues that arise in an international context.

Then the economics of unilateral, bilateral, and multilateral action are compared. The final analyses cover the optimal number of members in a multilateral agreement and the choice between mutually exclusive international agreements.
