Copyright has been increasingly internationalized and, recently, more and more harmonized. However, there has been little theoretical study of international copyright. This paper develops and analyzes a non-cooperative two-country model of copyright, where two countries trade in information goods and each with an open and competitive information goods industry sets copyright policy to pursue self-national interest. The model suggests that an increase in demand for information goods in a country calls for longer copyright protection in this country and shorter protection in its trading partner; decreases in fixed or per-product creative costs in a country with lower such costs call for marginally shorter protection; and an improvement in the economies of creative scale in a country with better economies of creative scale calls for marginally longer protection. Understanding these rational responses of nations to changes in creative technologies and markets should be helpful for international copyright-policy making.
