Free Trade Agreement and Vertical Trade with a Manufacturing Base

We examine the effects of free trade agreement (FTA) on tariffs and welfare in a three‐country model with vertical trade, where an FTA is formed between a country exporting a final good whose production involves using an intermediate good, and a country exporting the intermediate good in exchange for the final good. We demonstrate that the FTA reduces its member country's external tariff, whereas it raises the non‐member country's tariff. The non‐member country unambiguously becomes better off. In contrast, the FTA may or may not make its member countries better off. This implies that the formation of an FTA may not always be Pareto‐improving.     

Market Size and Firm Location in a Service Industry

This paper investigates the welfare effects of firm location in a service industry. We consider the situation where firms determine their locations in either of two regions with a difference in market size. From the viewpoint of the consumers' welfare, there are too few firms in the large market and too many in the small market. However, from the viewpoint of the producers' and social welfare, the opposite is true. Further, an increase in the difference in market size is unambiguously unfavorable for the producers. On the other hand, such an increase is favorable for the consumers and the economy as a whole.     

Vertical trade and free trade agreements

We investigate the effects of free trade agreements (FTAs) on tariffs and welfare in vertical trade. We consider a three-country model, where an FTA is formed between a country exporting a final good and a country exporting an intermediate good. The FTA unambiguously leads to a reduction in the member country’s tariff, but may cause the non-member country’s tariff level to increase. In the case, where FTA raises the non-member country’s tariff level, the FTA increases that country’s welfare. In contrast, the FTA may render its member countries better off. This result implies that the formation of an FTA may not always be Pareto-improving.     

Vertical specialization in North–South trade: Industrial relocation,wage and welfare

This paper presents a North–South trade model with vertically linked industries and examines how declining costs of trade across stages of production encourage vertical specialization and affect wages and welfare. As trade costs fall below a threshold, the production of all final goods relocates to the South and vertical specialization emerges. In some industries, production of intermediate goods also relocates against comparative costs because of benefits of co‐location, and further declines in trade costs lead to reshoring. A country may temporarily lose from falling trade costs, but both countries can be better off after trade costs fall sufficiently.     

Artificially Low Interest Rates as Export Promotion Policy

We reconsider the effects of a policy that sets an artificially low interest rate. Such a policy involves a combination of an interest rate ceiling and a rationing rule that assigns a priority‐lending status to export sectors over domestic service sectors. We demonstrate that the policy works as an export‐promotion policy, and improves national income. Furthermore, under some conditions, the policy expands the domestic service sector, despite the reduced amount of funds owing to the rationing rule. Finally, the artificially low interest rate improves national welfare.     

Location choice,competition, and welfare in non-tradable service FDI

We investigate whether non-tradable service FDI is efficient from a welfare point of view. A fixed number of firms strategically decide which markets to locate in and then compete in quasi-Cournot fashion. Considering firm location in two symmetric markets, non-tradable service FDI may or may not be efficient for the source country, depending on the total number of firms, competition in markets and the curvature of the demand function. In contrast, non-tradable service FDI is always efficient for the host country and the overall economy. This implies that any policy that affects firm location between two symmetric markets will not be beneficial from a welfare viewpoint.     

Standards policy and international trade: Multilateralism versus regionalism

We develop a simple model of policy coordination on domestic standards and examine whether domestic standards policy can lead to regional and multilateral harmonization of standards under the principle of national treatment. This paper focuses on mandatory product and process standards affecting the characteristics of a final good that control negative consumption externalities (e.g., vehicle emissions control and safety standards, restrictions on the use of pesticides for agricultural goods, and safety standards for electrical products). Only the products that meet a country's national standards are allowed to circulate in that country's market. Raising standards reduces negative externalities caused by consumption of a traded good but increases firms’ costs. We use the core as the solution concept. A standards regime is considered to be in the core if it is not blocked by any coalition within countries. The main finding is that a multilateral agreement on standards that maximizes world welfare is only in the core if externalities are local or slightly transboundary. Otherwise, only a regional agreement on standards is in the core. As extensions, we consider many and asymmetric number of firms, asymmetry in market size, fixed costs for different standards, and a multilateral agreement on different standards.     

Robust supply base management: Determining the optimal number of suppliers utilized by contractors

The importance of robust supply base management under demand uncertainty requires an understanding of the benefits associated with a contractor having an optimal number of suppliers. The key benefit is a reduction in a contractor's total cost of supply base management. However, few supplier-optimizing models incorporate the perspectives of both demand uncertainty and supply base management costs. The objective of this paper is twofold: (1) to investigate the dynamics between demand uncertainty and coordination; and (2) to develop a model that determines the optimal number of suppliers that a contractor should maintain in its supply base to become more flexible and maximize its profits.     

Trade promotion mode choice and information sharing in fashion retail supply chains

Trade promotion has a significant impact on the retail business, particularly in the fashion sectors. Manufacturers have traditionally been concerned with the inefficiency of trade promotion due to the low pass-through rate of the trade deals from retailers to customers. The scan-back (SB) trade deal, which monitors a retailer's sales via an IT system, benefits the manufacturer, but may or may not benefit the retailer. We provide insight into when a retailer in a two-stage supply chain has incentive to accept the SB trade deal. We show that (1) the manufacturer and the entire supply chain can always benefit from the SB trade deal while the retailer benefits only under some conditions, and that (2) both the retailer and the manufacturer can benefit from the SB trade deal if the SB deal is accompanied by a buyback (BB) contract. We examine the effect of a retailer's confidential pass-through rate on both the retailer's and the manufacturer's incentives to use the SB trade deal.
