We analyze the relationship between innovation attributes and competition intensity in a framework of endogenous knowledge spillover due to scientist mobility, and identify the effects of stronger patents on innovation at different levels of product market competition. We �nd non-monotone...

This paper investigates patterns of industrial dynamics and competition in the pharmaceutical industry, with particular reference to the consequences of patent expiry in different countries. We focus on the competition at the level of single chemical entities, distinguishing between original...

We study how best to reward innovators whose work builds on earlier innovations. Incentives to innovate are obtained by offering innovators the opportunity to profit from their innovations. Since innovations compete, awarding rights to one innovator reduces the value of the rights to prior...

This paper examines the role of intellectual property in developing countries in offshore outsourcing of R&D. We find that strengthened intellectual property protection in developing countries provides incentive for firms, both multinational and local, to specialize in undertaking an R&D...

The conventional viewpoint on the patent system is that it allocates market power in order to stimulate disclosure of information and create incentives for firms to innovate. This paper develops a dynamic equilibrium search model to show that, in sharp contrast to this traditional view, the...

This paper analyzes the effects of a stronger patent regime on innovation incentives, patenting propensity and scientist mobility when an innovating firm can partially recover its damage due to scientist movement from the infringing rival. The strength of the patent system, which is a function...

We consider an interaction of competing firms in an integrated world market and study their R&D incentives under each of product patent and process patent regimes. We follow a framework generally observed in the drug industry. We show that product patent regime leads to a larger R&D investment....

The longevity of cartels has been a highly contested topic among economists and managers, with numerous researchers arguing that cartels are inherently unstable and their endurance is usually short-lived. Understanding the main factors that influence a cartel duration is essential from a...

Existing studies on Behaviour-based price discrimination (BBPD) typically show that firms offer discounts to encourage consumers located middle of the line segment to switch in a duopoly model. However, in practice, some firms offer both this discount and a discount to encourage consumers with...
