We study the effect of the fragmentation of intellectual property rights on optimal patent design. The major finding is that when several complementary innovative components must be assembled to operate a new technology, the patentability requirements should be stronger than in the case of...

This research sheds light on the role of product scope on the innovation activity of multinational multi-product firms. We use patent citation data to break down innovation into two types by measuring the degree to which innovation performed by firms is fundamental and the extent to which the...

We study a quality-ladder model of endogenous growth that produces stochastic leadership cycles. Over a cycle, industry leaders can innovate several successive times in the same industry, gradually increasing the magnitude of their technological lead before being replaced by a new entrant....

We study the effect of the intellectual property rights (IPR) regime of a host country (South) on a multinational's decision between serving a market via greenfield foreign direct investment to avoid the exposure of its technology or entering a joint venture (JV) with a local firm, which allows...

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...
