Capital Imports and Tariffs

This paper develops a three‐sector, three‐factor specific factor model with a tariff and presents conditions under which capital imports and tariffs can be welfare enhancing in a developing country. The impact on welfare depends on the tariff revenue effect and the repatriation effect. A capital import is welfare enhancing if it reduces the domestic output of imports. A tariff is welfare enhancing only if it reduces the return to foreign capital.     

Welfare‐Worsening Aid Flows To Small Countries: The Role of Nontraded Goods

This paper presents the circumstances under which foreign aid can immiserize a small, tariff‐distorted economy, highlighting the role played by the nontraded sector in generating this outcome. An inflow of aid, provided in the form of an increase in the capital stock, can reduce real income of a small, tariff‐distorted economy if: (i) the inflow results in an increase in the price of the nontraded good and the nontraded good and imports are sufficiently strong complements in demand; or (ii) if the inflow leads to a reduction in the price of the nontraded good and the nontraded good and imports are substitutes in demand, provided the degree of substitutability is not too large.     

Tax Principles and Tariff‐Tax Reforms under International Oligopoly

In a two‐country duopoly model, this paper compares destination‐ and origin‐based commodity taxes adjusted to tariff reductions so that the world price and foreign welfare remain unaltered. We first find that this tariff‐tax reform reduces domestic welfare under the destination principle while the opposite holds under the origin principle. Then, it is shown that this ranking is reversed if exports are taxed. In short, which is preferable between destination and origin taxes depends on the tax principle and which between imports and exports are taxed.     

Revenue-Neutral Environmental Tariff Reform, Growth, and Welfare

This paper analyzes the growth and welfare effects of revenue‐neutral tariff reform in a small open endogenous growth model with environmental externalities. As is the case in countries that depend primarily on imported energy, the employment of a foreign intermediate good causes negative environmental externalities in production. This paper shows that substituting a tariff on the foreign intermediate good for a tariff on the foreign consumption good in a revenue‐neutral way raises the growth rate and the welfare, if the environmental externality is sufficiently strong and if the elasticity of substitution between inputs lies within a certain range.     

Equity Control of Multinational Firms: Effects on Resource Allocation and National Welfare

In this paper, we re-examine the effects of equity control of multinational firms on resource allocation and national welfare in a model with rural–urban migration and urban unemployment. A large number of recipient (host) countries are developing countries with dual economies. We indicate, among other things, that a restriction on multinational investment may lower the unemployment rate and increase the total employment in the host country. Furthermore, we find that the restriction on multinational investment raises the national welfare in the host economy if the tariff imposed on imports is sufficiently large and the difference between domestic and foreign capital rental is sufficiently small.     

Why Free Trade May Hurt Developing Countries

This paper builds a general equilibrium trade model where a country produces two traded goods and one nontraded public consumption good. The government finances the provision of the public good by taxing the incomes of factors of production, and/or by imposing tariffs. Within this framework, the paper (i) shows that a small tariff or an income tax improves the country's welfare if there is an undersupply of public good, and (ii) identifies the circumstances in which an improvement in the country's terms of trade may reduce its welfare, and free trade can be inferior to autarky. A terms of trade improvement, or the movement from autarky to free trade, definitely improves the country's welfare if the government imposes a tariff that leaves the domestic relative price of the imported good unchanged.     

Tariff,Growth, and Welfare

We develop a two‐country (Home and Foreign) by two‐good (consumption good and investment good) by one factor (capital) endogenous growth model with international knowledge spillover to study the relationship between an import tariff and economic growth and welfare. First, unlike the past literature, we do not need to make an assumption such that the growth rates between countries are identical in a balanced growth path (BGP). Second, we show that there exists a unique and saddle‐point BGP with both countries being incompletely specialized. Third, a higher import tariff on the consumption good in the domestic country may boost (reduce) the rate of economic growth when the foreign (domestic) country has an absolute advantage in the investment good. Finally, a rise in the tariff rate by one country may improve world welfare under some parameter spaces.     

Trade costs, wage rates, technologies, and reverse imports

Abstract .  This paper explores the effects of transport costs, tariffs, and foreign wage rates on the domestic economy in the presence of reverse imports, with special emphasis on inter-firm cost asymmetry in an international oligopoly model. To serve the domestic market, a foreign firm produces in the foreign country, while two domestic firms produce either at home or abroad. Surprisingly, an increase in the foreign wage rate may increase the profits of a firm producing in the foreign country. Even if all firms produce in the foreign country, an increase in the foreign wage rate may improve domestic welfare.     

Foreign-Investment Tax and Tariff Policies in Developing Countries

In this paper we examine the welfare effects of tax on foreign capital and tariff policies for a small open economy with sectoral unemployment. The individually and jointly optimal tax and tariff rates in the absence or presence of international tax credits are derived. A subsidy on foreign capital coupled with a tariff can be jointly optimal when tax credits are absent in the source country. However, the capital subsidy policy may fail to hold when the foreign country follows a tax credit system.     

Vertically related markets, tariffs, and technology adoption

This study considers the effect of trade policy on the time of technology adoption. Home firm is dependent on a foreign vertically integrate firm for supplies of a key input before the technology adoption and can produce the intermediate input after the technology adoption. Both firms compete by Cournot in the home final product market. I show that the decrease in the tariff on final product imports and the increase in the tariff on input imports create incentives for earlier technology adoption by home firm. While maximizing the discounted sum of welfare, the domestic government should protect home firm initially. Further, provided the cost of technology adoption declined sufficiently over time, the domestic government should stimulate the earlier technology adoption by decreasing the tariff on final product imports and increasing the tariff on intermediate product imports.     

Economic liberalization and welfare in a model with an informal sector

The paper reexamines the conventional results relating to inflow of foreign capital, removal of protectionism and structural reform programmes, in a small open economy in terms of a two-sector general equilibrium model with an informal sector. The paper shows that in the presence of labour market distortion and a protectionist policy, inflow of foreign capital may be desirable irrespective of the pattern of trade of the economy due to its favourable impact on welfare. But the welfare implications of tariff reductions and/or structural adjustment programmes, such as deregulating the formal sector labour market, depend crucially on the economy's trade pattern. The paper provides an answer to the question as to whether in a developing economy labour market reform and tariff reform should go hand-in-hand or whether one should precede the other for welfare improvement.

Capital income taxation in a growing world economy

This paper deals with dynamic adjustment in large economies to changes in the rate of capital income taxation or in the rate of investment tax credit in one country. The framework applied in the paper is a continuous-time, overlapping generations model with two countries. It features population growth and debt non-neutrality. We address impact and steady state effects of capital income tax and investment subsidy changes in the home country on consumption per capita, the capital intensity, and the per capita net foreign asset position in both countries. We also briefly consider individual welfare consequences of these policies.     

Optimal policy for environmental goods trade in asymmetric oligopolistic eco-industries

In this paper, we examine the optimal structure of an environmental tax to pollution, a production subsidy to a domestic eco-industry, and an import tariff on environmental goods (EGs) in a two-country model where the home country imports EGs from the foreign country. Home and foreign firms that produce EGs engage in Cournot competition. We then assume that the number of the home local firms which produce EGs is constant, but that of the foreign firms is variable. Our main findings are as follows: (I) The optimal environmental tax level may be lower than the Pigouvian level even if the tax has a positive impact on the output of EGs produced by a domestic firm. (II) The optimal tariff level may be positive when the country implements the first best policy combination in a closed economy regarding the environmental tax and the subsidy. (III) The optimal subsidy level may be positive, and then the subsidy may be substitutive for the import tariff on EGs.     

Illegal Immigration and Second-best Import Tariffs

A version of the small‐union Meade model is presented to analyze the illegal immigration problem in the context of import tariffs. Two possible host nation objectives are considered: (i) to control the level of illegal immigration to a given target; or (ii) to choose an illegal immigration level that maximizes national welfare. Available policy instruments are import tariffs/subsidies, border, and internal enforcement levels. The second‐best tariff on imports from the source nation (for illegal immigration) can be of either sign. It depends on the effect of the tariff on the wage rate and the pattern of substitutability in consumption. In scenario (ii), greater enforcement may be justified if it reduces labor inflow and thereby contracts the protected sector. If enforcement is too costly, tariff policy may substitute for it to exploit monopsony power in the labor market and to counter the distortionary effects of labor flows.     

Growth,revenue, and welfare effects of tariff and tax reform: Win–win–win strategies

We examine growth, revenue, and welfare effects of tariff and tax reform with a two-good, two-factor endogenous growth model. Learning-by-doing and intersectoral knowledge spillovers contribute to endogenous growth consistent with incomplete specialization. We obtain two main results. First, trade liberalization raises (or lowers) the growth rate if and only if the import sector is more effective-labor-intensive (or capital-intensive). Second, we can attain growth, revenue, and welfare gains by combining consumer–price–neutral tariff and tax reform for growth enhancement with an additional rise in the consumption tax on the less distorted good.     

Foreign Factor Ownership and Optimal Tariffs

In the presence of foreign factor ownership tariffs change not only the terms of (goods) trade but also income flows between countries. Assume that only the home country owns factors abroad. Then the optimal tariff is negative if and only if foreign factor ownership entails trade-pattern reversals. Trade-pattern reversals are neither a necessary nor a sufficient condition for a negative optimal tariff if the foreign country owns factors in the home country. Changes in the home country's tariff shift the foreign country's offer curve. This adds a new dimension to optimal tariff analysis.     

The domestic content of imports and the foreign content of exports

When a country imports goods that have been assembled abroad, some amount of the labor and capital services embodied in those goods may originally be from the country that is now importing them. Similarly, some of the value added of a country's exports may be foreign in origin. For the median country in my sample of 14, I calculate that 21.5% of imported labor services are domestic labor, 17.7% of imported capital services are domestic capital, 12.3% of exported labor services are foreign labor, and 23.3% of exported capital services are foreign capital.     

Environmental capital flight and pollution tax

This paper analyzes the impacts of a production pollution tax on environmental capital flight and national product in a two-country static general equilibrium model with two-way foreign investment. It is assumed that the capital input in both countries is a composite good of domestic and imported capital. And pollution is assumed to originate in the production process. The productivity of capital in each country is negatively (or positively) related to the worldwide aggregate emissions.The analysis shows that when a domestic pollution tax is levied, domestic capital outflows increase and foreign capital inflows decrease for sufficiently high elasticities of substitution between labor (immobile input) and capital (mobile input) in both countries. Moreover, with negative transnational externalities, increases of a domestic pollution tax reduce domestic production and increase foreign production. The difficulty of substitution between immobile and mobile inputs hinders the optimal allocation of worldwide capital and national product. In this paper, the optimal pollution tax is based on global welfare maximization, not on global income maximization, taking into consideration the impact of income change on individual welfare. Therefore, an optimal pollution tax in the developing country should be lower for a given rate of pollution.     

A Model of Welfare Enhancing Capital Imports

This paper proposes a model of welfare enhancing capital imports in a multi‐dimensional framework. Contrary to the pessimistic conventional wisdom of capital imports and welfare, a justification is provided for the acceptance of foreign capital in developing countries.     

Interest Groups, Trade Liberalization, and Environmental Standards

In considering a country that imposes a minimum standard on an imported polluting good, which generates negative consumption externalities, we construct a common-agency model, in which a domestic environmental group and a foreign industrial lobby can influence the formation of the minimum standard by providing political contributions to the government. This paper investigates the effects of trade liberalization on the political equilibrium environmental standard, the pattern of trade, environmental disutility, and social welfare. We find that trade liberalization tightens the minimum standard, decreases imports of the polluting good, and reduces environmental disutilities. The importing country’s social welfare, however, does not necessarily increase with trade liberalization. The weaker the environmental group’s lobbying efficiency, or the stronger the foreign firm’s lobbying efficiency, the more likely it is that trade liberalization will enhance the importing country’s welfare.
