This paper examines how the option for licensing affects research and development (R&D) and social welfare.We find that if cost reduction from R&D is sufficiently small and there is an option of licensing, firms will do non-cooperative R&D. In absence of licensing, firms will do cooperative R&D...

This paper examines how the option for licensing affects research and development (R&D) and social welfare. We find that if cost reduction from R&D is sufficiently small and there is an option of licensing, firms will do non-cooperative R&D. In absence of licensing, firms will do cooperative R&D...

In this paper we show how the size of innovation can affect the incentive for cooperative R&D and social welfare. When cost difference between large and small innovations is not sufficiently large then social welfare can be more under small innovation compared to large innovation. However, the...

An important discussion in recent years is the introduction of product patentsand the abolition of process patents. In a model with endogenous number of innovatingfirms, we show that whether product patent increases R&D is ambiguous, and depends onthe type of market demand and the cost of R&D....

This paper considers welfare effects of entry when the incumbent firmbehaves like a Stackelberg leader in the product market. In contrast to previous work(Klemperer, 1988, Journal of Industrial Economics), we show that entry may alwaysincrease welfare. Using general demand function, we show the...

We show the welfare effects of entry in presence of technology licensingunder Cournot competition. If the entrant is technologically inferior to that of theincumbent then, though licensing reduces (or completely eliminates) excessive entryfor relatively low entry costs, it creates excessive...

We show that a monopolist input supplier licenses its technology to create a second source of input supply if second sourcing increases competition in the final goods market. We also show that welfare increases under second sourcing...

This paper considers the effects of entry in the final goods market when the input market is imperfectly competitive. We show that entry of a new firm may increase profit of the incumbent if the technology of the entrant is sufficiently inferior to that of the incumbent...

We show the effects of entry of a domestic firm and a foreign firm on welfare, in presence of licensing. In case of licensing with up-front fixed-fee, domestic entry increases welfare if the technological differences between the firms are not very large, whereas foreign entry increases welfare...

This paper shows that technology licensing may be socially undesirable. Possibility of licensing increases the incentive for entry and thus, increases competition. If technology of the incumbent and entrant is sufficiently close, licensing-induced entry reduces social welfare. Otherwise,...
