The paper analyzes a dynamic model of R&D investment with inter- and intrasectoral R&D spillovers, in which the profitability of an invention in one sector increases if there is an innovation in another sector. Interpreting intrasectoral R&D spillovers as a measure of intellectual property...

Counterfeit money is the topic of television, movies, and lore but hardly seen by most of us - for only about one in ten thousand notes is found to be counterfeit, annually, in the USA (Judson and Porter 2003). And while the value of globally seized and passed counterfeit American dollars has...

This article investigates the relation between the level of publicness of digital goods - i.e. their degree of non-excludability and non-rivalness - and the pirating behaviour of the consumers. The main focus is put on the difference between the ex-ante level of publicness - determined by the...

Policymakers all over the world claim: no innovation without protection. For more than a century, critics have objected that the case for intellectual property is far from clear. This paper uses a game theoretic model to organise the debate. It is possible to model innovation as a prisoner's...

We develop a model to analyze one mechanism under which stronger intellectual property rights (IPR) protection may improve the ability of firms in developing countries to break into export markets. A Northern firm with a superior process technology chooses either exports or technology transfer...

We introduce international mobility of knowledge workers into a model of Nash equilibrium IPR policy choice among countries. We show that governments have incentives to use IPRs in a bidding war for global talent, resulting in Nash equilibrium IPRs that can be too high, rather than too low, from...

We develop a model in which stronger protection of intellectual property rights has an inverted U-shaped effect on innovation. Intellectual property rights protection allows the incumbent firms to capture part of the rents of commercial exploration that would otherwise accrue to the...

This paper analyzes welfare implications of protecting intellectual property rights (IPR) in the framework of TRIPS for developing countries (South) through its impact on innovation, market structure and technology transfer. In a North-South trade environment, the South sets its IPR policy...
