This paper seeks to explain why some pharmaceutical companies are observed to withdraw their products before patents are expired and simultaneously introduce new patented (competing) products. Given the specific nature of drug markets, the companies in fact increase the entry cost of the...

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 paper studies incentives for cooperative research vis-à-vis non-cooperative research under incomplete information when the R&D outcome is stochastic and continuously distributed with a given mean and a constant variance. We show that the non-cooperative R&D incentive increases with the...

We construct a model to show that outsourcing of a crucial input can occur even though it can be produced in-house at a lower cost. There are two firms producing differentiated goods and competing in prices, and only one of them possesses input production technology which is superior to that of...

In a Cournot duopoly with one foreign firm and one domestic firm we show that a tariff on foreign products can be an effective instrument to influence the licensing strategy of the foreign firm. Under free trade technology transfer occurs with a royalty contract, but a suitably designed tariff...

This paper studies incentives for cooperative research vis-à-vis non-cooperative research in an incomplete information framework. We show that with quantity competition under asymmetric information, the expected payoff from non-cooperative research goes down compared to the case of symmetric...

The purpose of this paper is to propose a model where trade has a direct and positive impact on growth rate of two trading nations beyond the level effect. We use the idea of virtual trade in intermediates induced by non- overlapping time zones and show how trade can increase the equilibrium...

We study the implication of credit constraints for the sustainability of product market collusion in a bank financed Cournot duopoly when firms face an imperfect credit market. We consider two situations without or with credit rationing. When there is no credit rationing moderately higher cost...

The main purpose of this study is to illustrate, with a simple two-factor (skilled and unskilled labor) model, how a time-saving improvement in business-services trade benefitting from differences in time zones can have an impact on national factor markets. In doing so, we intend to capture the...

We build up a Ricardian trade model for a small open economy with imperfection in the market for credit which eventually affects the pattern of production and trade. Workers/entrepreneurs are endowed with different levels “capital” and need to borrow to produce the credit intensive good....
