In a successive Cournot oligopoly, we show the welfare effects of entry in the final goods market with no scale economies but with cost difference between the firms. If the input market is very concentrated, entry in the final goods market always increases welfare. If the input market is...

Common wisdom suggests that entry reduces profits of the incumbent firms. On the contrary, we show that if the incumbents differ in marginal costs and the entrants behave like Stackelberg followers, entry may benefit the incumbents who are relatively cost efficient while it always hurts the cost...

Whether higher productivity of the foreign firm increases host country welfare depends on whether the reason for foreign direct investment (FDI) is to save the trade cost or to get the advantage of cheap labor. We show that, if the reason for FDI is to get the advantage of cheap labor, higher...

It is usually believed that higher competition, implying more active firms, benefits consumers and encourages the antitrust authorities to foster competition. We show that this view can be misleading, and higher competition may actually make the consumers worse-off. We suggest that the antitrust...

Despite the important insights it has provided, technology licensing literature remains restrictive by not allowing government policies. We show that in the presence of strategic tax policies, an outside innovator and, more interestingly and in contrast to the existing works, the consumers are...

This paper studies the role of separation of ownership and management in determining the welfare implications of entry in oligopolistic markets. We show, in the presence of managerial incentive schemes with cost asymmetry, that entry is socially insufficient unless scale economies are very...

The literature analysing social efficiency of entry argues that entry is always socially excessive in industries with asymmetric cost firms and no scale economies. We show that exogenous cost asymmetry is responsible for this result. In a simple model with endogenous R&D investment by the more...

We show the effects of product differentiation and competition on technology licensing by an outside innovator. Both the innovator and the society are better off under royalty licensing compared to auction (or fixed-fee) if the number of potential licensees is sufficiently large, irrespective of...

Considering a move from monopoly to duopoly, Bastos et al. (“Open shop unions and product market competition”, 2010, Canadian Journal of Economics) provides open-shop union, where the union density is less than one, as a theoretical reason for the evidence of a positive relationship between...

We provide a theoretical justification for bi-sourcing, which refers to the situation where a final goods producer buys an input from an outside supplier and also produces it in-house. Bi-sourcing occurs if the marginal cost of producing the input in-house is higher than the marginal cost of...
