South Korea, like many countries, is engaged in a policy debate concerning possible railways reforms. However, unlike most countries, here the focus of discussion has been the government’s proposal to open high-speed passenger train lines to a second train company that would supply on-track...

We investigate a differentiated mixed duopoly in which private and public firms can choose to strategically set prices or quantities by facing a union bargaining process. For the case of a unionized mixed duopoly, only the public firm is able to choose a type of contract irrespective of whether...

The paper examines the timing of endogenous wage setting under Bertrand competition in a unionized mixed duopoly. The results are that when the public firm chooses the timing of wage setting: (1) sequential wage setting is the outcome and (2) simultaneous wage setting is the outcome. The first...

This paper investigates Bertrand competition of unionized mixed duopoly when the public firm is less efficient than the private firm, including endogenous imposition of the budget constraint on the public firm. Thus, we show that if the public firm's inefficiency is sufficiently small, no...

This study investigates social welfare and privatization depending on the government's preference for tax revenues and the timing of wage setting in either a unionized-mixed or a unionized-privatized duopolistic market. We show that bargaining over wages is always sequential regardless of who...

This paper examines the issue of the first-mover and second-mover advantage in a vertical structure in which each manufacturer trades with a separated retailer via two-part tariffs. Compared to the canonical result in one-tier market, we find that the manufacturers' preference orderings over...

We investigate government subsidy policies in which a home firm and a foreign firm choose to strategically set prices or quantities in a third market. We show that even though each firm can earn higher profits under Cournot competition than under Bertrand competition regardless of the nature of...

By introducing the government's preference for tax revenues into unionized mixed duopolies, this paper investigates how the preference can change the government's choice of tax regimes between ad valorem and specific taxes. Main results are as follows. Given that one of the tax regimes is...

We investigate government subsidy policies in which a home firm and a foreign firm choose to strategically set prices or quantities in a third market. We show that even though each firm can earn higher profits under Cournot competition than under Bertrand competition regardless of the nature of...

This paper examines the endogenous choice of competition mode with strategic export policies in vertically related markets. We show that (i) regardless of the nature of goods, choosing Bertrand competition is the dominant strategy for downstream firms, which leads downstream firms to face a...
