We provide a new explanation for a profitable horizontal merger between Cournot oligopolists with symmetric constant returns to scale technologies and homogeneous goods. We show that a merger can be profitable if it prevents a foreign firm from undertaking FDI. Our result is due to the effect of...

This paper considers the effect of outsourcing on R&D of the contracting firm. We show that outsourcing increases (decreases) R&D investment in a declining (booming) industry. If outsourcing reduces potential R&D investment, it may also make the consumers worse off. We show that outsourcing...

Recent empirical evidences show negative relationship between outsourcing and profitability. This paper provides a theoretical explanation for this phenomenon. In an oligopoly model, we show that firms earn lower profits in the outsourcing equilibrium compared to the situation where neither firm...

We consider the impact of horizontal mergers in the presence of free entry and exit. In contrast to much of the previous literature on horizontal mergers, our model yields predictions that seem intuitively reasonable: with only moderate cost synergies mergers of a small number of industry...

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

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

We show that, for licensing by an outside innovator in a Cournot oligopoly,royalty licensing can generate higher payoff to the innovator than the fixed-feelicensing and auction if the labor market is unionized...

We show the incentive for divisionalization by a monopolist producer. Incontrast to the previous literature, where divisionalization occurs for product marketadvantage, we show that divisionalization occurs if it provides strategic advantage inthe labor market. With unionized labor market, we...

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....

We show the effects of Bertrand and Cournot competition on R&D investmentand social welfare in a duopoly with R&D competition where success in R&D isprobabilistic. We show that R&D investments are higher under Bertrand (Cournot)competition when R&D productivities are sufficiently low (high), and...
