It is often argued, though mostly informally, that outward foreign direct investment (FDI) is a synonym for the export of employment and thus detrimental to the home economy. To see whether and under what conditions this intuition indeed holds true, we construct a model of unionized duopoly and...

We construct a monopolistic competition model considering different markups across industries and firm-level heterogeneity of productivity. An excess entry occurs in low-markup (competitive) industry, and vice versa in high-markup (non-competitive) industry. To achieve the optimum allocation, a...

I revisit supplier encroachment under the framework of a two-part tariff contract. When a monopoly manufacturer supplies competing retailers and each retailer's contracting process is unobservable to the rival, the retailer's lack of knowledge vis-à-vis its rival's contract may undermine the...

We consider a bilateral monopoly in which a manufacturer can open its direct channel that is less efficient than the existing retailer. We find the following results. The manufacturer opens its direct channel if its bargaining power over the existing retailer is weak. Opening the direct channel...

Incorporating weakly nonseparable preferences into the familiar time-preference model, we emphasize a role of steady-state welfare changes in determining the effect of permanent tariffs on the current account. The effect consists of: a welfare effect, due to steady-state welfare changes, which...

Foreign direct investment (FDI) gives foreign firms access to local labor and inputs, thereby harmonizing costs between foreign and domestic firms relative to exports. This paper investigates the welfare effects of such cost harmonization in strategic environments, finding that when the number...

We investigate the effects of restricting locations of firms into Hotelling duopoly models. In the standard location-price models, the equilibrium distance between firms is too large from the viewpoint of consumer welfare. Thus, restricting locations of firms and reducing the distance between...

In a Diamond-type overlapping-generations setting public debt issuance places no burden on future generations including those who repay the debt if prices and wages are fixed and unemployment occurs in the periods in which public bonds are issued and repaid. Whether the collected fund is spent...
