Shared Renewable Resources: Gains from Trade and Trade Policy

This paper examines the effects of international trade and trade policy in a two‐country, two‐good model with an open‐access renewable resource that is internationally shared. We show that both countries may still benefit from trade when they specialize in the production of their comparative advantage good, although the shared resource is reduced by trade. In addition, we demonstrate that the steady state utility of a resource‐good importing country may be reduced by trade, even if it specializes in the production of a non‐resource good. Import tariffs and export taxes on a resource good may increase or decrease the shared stock level depending on the production patterns in a trading steady state. The trade policy is likely to be Pareto‐improving when the shared stock rises, while both countries may be made worse off by the trade policy when the shared stock falls.     

WELFARE EFFECTS OF TECHNOLOGY TRANSFER

Abstract.  This paper examines the welfare effects of aid tied to technology transfer in a two-country general equilibrium model. In the recipient country, some factors of production employed in a particular industry are difficult to use in other industries because their properties are specific to that industry. Technology transfer facilitates 'factor movement' and improves the efficiency of factor markets in the recipient. We identify and interpret the conditions under which technology transfer benefits the recipient and harms the donor. We also show that technology transfer can enrich (or harm) both the donor and the recipient under certain conditions.     

Shared renewable resources and gains from trade under technology standards

Using a two‐country, two‐good model of international trade, we examine gains from trade and strategic interaction in resource management among countries that share renewable resources such as fishery stocks. Two goods are a resource good, which is the harvest of the shared stock, and some other good that may be thought of as manufactures. The productivity of the resource good depends on harvesting technology and the stock level. This paper focuses on technology standards (e.g., restrictions on fishing gears, vessels, areas, and time) over other methods for resource management because they are most commonly implemented in fisheries. Technology standards are modeled as a restriction on the harvesting technology; that is, under strict technology standards, firms exploit resources as if they are using inferior harvesting technology. We show that an opening up of trade may reduce the shared stock and cause steady‐state utility to decrease in a resource‐good importing country and increase in a resource‐good exporting country. Strikingly, when the shared stock is in jeopardy (a high demand for the harvest), steady‐state harvest is maximized after an opening up of trade by what we call multilateral resource management in this paper and both countries gain from trade.     

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.     

Transboundary Pollution and the Welfare Effects of Technology Transfer

We examine the welfare effects of a transfer of pollution abatement technology in a two-country model. In each country, one industry discharges pollution as a byproduct of output, and the sum of domestic and cross-border pollution decreases the productivity of the other industry. We show the effects of technology transfer on the terms of trade, pollution levels, and welfare. Technology transfer decreases the pollution affecting each country under certain conditions. We derive and interpret the conditions under which technology transfer enriches the donor and the recipient. The results essentially depend on the trade pattern and the fraction of cross-border pollution.     

Tied Aid and Welfare

In this paper we present a model of tied aid to shed light on the dispute between Kemp and Kojima (1985 ) and Schweinberger (1990 ) and to complement their analyses. We show that if the households of the recipient country are not informed of the transfers at their consumption decision, they have an incentive to trade the purchased goods from their domestic production income whenever transfer paradoxes occur. We also demonstrate that when they are aware of the transfers and can trade the purchased goods from their production income, there are no transfer paradoxes under the normality condition of commodities.
