THE WELFARE EFFECTS OF FOREIGN CAPITAL INFLOW WITH TARIFF-RIDDEN AND QUOTA-RESTRICTED IMPORTS*

The welfare effects of foreign capital inflow and changes in the foreign price and tariff rate of a tariff-ridden imported good are considered for a small country for both 3 times 2 and 3 times 3 trade models with a quota-restricted imported good (whose special case is a nontraded good). For the 3 times 2 model, foreign capital inflow does not affect home welfare when there is no tariff on imports, but it harms the home country if a tariff is imposed on the imports to the extent that the tariff-ridden imported good is more capital intensive than the exported good. On the other hand, for the 3 times 3 model the foreign-capital inflow benefits the home country if the tariff rate is below a certain level under the analogous capital-intensity assumptions. The welfare effects of changes in the foreign price of the tariff-ridden good and its tariff rate remain the same for both models.     

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.

Optimal Tariff Policy on Imports from Multinationals*

Using partial equilibrium analysis, it is shown that for small countries there is an optimal tariff on imports from a monopolistic multinational. There is also (under specified circumstances) a tariff at which the multinational finds subsidiary production more profitable than exports: the switchover tariff. The interaction between the optimal and switchover tariffs is analyzed from the small country's welfare standpoint. The conclusion is that there is not one, but a variety of possible optimal policies for the country: trade at the optimal tariff, with or without prohibition of subsidiary production, or tariff-protected subsidiary production.     

Mergers and Trade Policy under Oligopoly

For an oligopolistic industry, the effects of mergers on the domestic country's optimal trade policy are analyzed. If the domestic country pursues an optimal trade policy then it will always lose as a result of a foreign merger. The optimal domestic response to a foreign merger is to decrease (increase) the tariff if demand is concave (convex) and to increase the production subsidy. The foreign merger reduces foreign welfare when the domestic country pursues its optimal trade policy. The optimal domestic response to a domestic merger is to leave the tariff unchanged and to increase the production subsidy.     

Dynamic Interactions in Trade Policy in a Differential Game Model of Tariff Protection

This paper develops a two‐country dynamic game model of tariff protection to reconsider optimal trade policies and their implications for welfare. The authors show that an import subsidy is optimal in the feedback Nash equilibria, which results in a curious possibility that the domestic market is monopolized by the foreign firrm. However, welfare comparisons among Nash equilibria, free trade, and autarky reveal that feedback Nash equilibria involve higher welfare than both autarky and free trade, i.e. dynamic noncooperative choices of policy serve as tacit policy coordination and ensure larger trade gains relative to free trade.     

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.     

Tariff Reductions in the Presence of Foreign Direct Investment

This paper argues that the welfare effects of trade liberalization in the presence of foreign direct investment obtained under perfect competition cannot be extended to imperfectly competitive markets. In the Heckscher-Ohlin model, trade liberalization may be paradoxically immiserizing when the traditional welfare-increasing result is corrected for the change in foreign capital revenue. Under imperfect competition this cannot occur, except under rather implausible assumptions. Indeed, a tariff reduction is expected to increase welfare when the welfare indicator is corrected for the presence of foreign capital, regardless of the type of market structure and the form of competitive rivalry.     

Tariffs and privatization policy in a bilateral trade with corporate social responsibility

Corporate social responsibility (CSR) has become a global business strategy and thus it provides significant welfare implications for designing optimal policies. This paper investigates the impact of CSR on policy interaction between tariffs and privatization in an international bilateral trade model. We find that CSR is closely related to the government's policy decisions on tariffs. In particular, we find that the strategic tariff for increasing domestic welfare is always higher (lower) than the efficient tariff for improving global welfare when the degree of CSR is low (high). We also show that a privatization policy raises tariff and worsens (improves) domestic welfare when the degree of CSR is low (high). Finally, we demonstrate that both countries choose a nationalization policy even though the privatization policy is globally optimal when the degree of CSR is high.     

Tariffs,Quotas, and Forward Contracts under Asymmetric Information*

We consider optimal trade policy for a large country with private information. We show that the optimal tariff leads to a signaling equilibrium with higher tariffs and lower welfare than under complete information, whereas the optimal import quota replicates the complete information equilibrium and thus is superior to the tariff. We also show that, with the tariff, the country may be better off being uninformed. Finally, we show that if the importing nation cannot commit to its tariff, the use of futures contracts together with the dynamically consistent tariff leads to the same equilibrium as under complete information with commitment.     

The Mercantilist Index of Trade Policy*

We introduce an index of trade policy restrictiveness defined as the uniform tariff that maintains the same trade volume as a given tariff/quota structure. Our index overcomes the problems of the trade‐weighted average tariff: It avoids substitution bias, correctly accounts for general equilibrium transfers, and takes import volume instead of welfare as benchmark. Empirical applications to international cross section and time‐series comparisons of trade policy confirm our theoretical results: Trade‐weighted average tariffs generally underestimate the true height of tariffs as measured by the trade‐volume‐equivalent index; this in turn always underestimates the welfare‐equivalent index.     

Privatization in a Small Open Economy with Imperfect Competition

We look at privatization in a general equilibrium model of a small, tariff‐distorted, open economy. There is a differentiated good produced by both private and public sector enterprises. A reduction in government production in order to cut losses from such production raises the returns to capital and increases the tariff revenue, which are welfare‐improving. However, privatization also leads to lower wages and possibly fewer private brands. This lowers workers’ welfare, which may make privatization politically infeasible. Privatization can improve workers’ welfare with complementary reforms, e.g., attracting foreign investment or trade liberalization.     

Gains and losses from potential bilateral US–China trade retaliation

Two closely related numerical general equilibrium models of world trade are used to analyze the potential consequences of US–China bilateral retaliation on trade flows and welfare. One is a conventional Armington trade model with five regions, the US, China, EU, Japan and the Rest of the World, and calibrated to a global 2009 micro consistent data set. The other is a modified version of this model with monetary non-neutrals and including China's trade surplus as an endogenous variable.Who may gain or loss from global trade conflicts spawned by adjustment pressures in the post crisis world is much debated. In a US–China trade conflict, Europe and Japan would seem gainers from preferential access to US and Chinese markets. The loss of markets would hurt the US, but moving closer to an optimal tariff could be the source of terms of trade gains. And the ease of substitution across trading partners' practices would determine costs for China.Results from the conventional model suggest that retaliation between the two countries can be welfare improving for the US as it substitutes expenditures into own goods and improve its terms of trade with non-retaliatory regions, while China and non-retaliatory regions may be adversely affected. Results in the endogenous trade surplus model from the central case model specification, however, suggest that both the US and the EU (the deficit regions) have welfare losses in most cases, while the surplus region, China, and the ROW have welfare gains. In both models, when the bilateral tariff rates are very high, gains accrue to the EU and Japan from trade diversion if the substitutions elasticities of imports are high. Costs are borne by the US and China in lost exports, lowered terms of trade and adjustment costs at home.     

A Welfare Ranking of Multilateral Reductions in Real and Tariff Trade Barriers when Firms are Heterogenous

Trade liberalization comes about through reductions in various types of trade barriers. This paper introduces, apart from the customary real trade costs (i.e. iceberg and fixed export costs), two revenue generating trade barriers (i.e. an ad valorem tariff and a trade license) into a standard heterogeneous‐firms‐trade model with Pareto distributed productivities. We derive analytical welfare rankings of all four liberalization channels for an equal effect on two openness measures, for any trade cost level and while all four barriers are simultaneously present, i.e. for any initial equilibrium. We show that when openness is measured at retail prices, not border prices, the welfare rankings are sensitive to the degree of efficiency in revenue redistribution, e.g. the share of tariff revenues wasted on rent‐seeking activities. As a result, multilateral tariff reductions can switch from the least to the most preferred mode of liberalization. Among the other three barriers we establish a universal welfare ranking for any strictly positive level of revenue redistribution and for either measure of openness.     

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.     

The Effects of Trade Liberalization between Heterogeneous Countries on Endogenous Mergers

This paper examines the effects of trade liberalization on merger behavior. We endogenize merger choice among owners in an oligopolistic industry in asymmetric countries to analyze the consequences of trade cost reductions on competitiveness and welfare. In this context, the non‐cooperative game supports asymmetric market structures. We also find that trade liberalization is not necessarily pro‐competitive in countries with the competitive advantage, even if trade costs are completely abolished. Moreover, the tariff‐jumping explanation of international mergers does not necessarily apply. The welfare analysis shows that merger behavior can significantly alter any gains from liberalization. Countries should consider enforcing competition in regional agreements. Specifically, to avoid a reduction in domestic welfare following trade‐liberalizing reductions in trade costs, a high‐cost country's optimal policy may be to ban international mergers.     

Flexible and welfare-consistent tariff aggregation over exporter regions

In this paper we improve on existing tariff aggregation techniques in applied equilibrium models (AEM) with the aim of correcting for two sources of bias in simulated welfare results: (1) aggregation over exporter regions with significant tariff dispersion and (2) variable tariff rates determined by Tariff Rate Quota (TRQ) regimes. Both aspects seem important due to an increasing number of bilateral FTAs which drive up tariff divergence across countries and tend to apply TRQs, at least temporarily. We demonstrate that the proposed aggregation technique can handle both tariff and non-tariff barriers to trade by combining a number of tariff indexes in a modified trade balance condition in a welfare-consistent manner. Additionally, different rent-allocation shares for TRQs can be easily introduced in our methodological extension. We also address the implications of some rather strict behavioral assumptions with regard to demand that welfare consistent aggregation requires. An empirical analysis of the Korean dairy market in the EU–South Korea FTA using the proposed method shows that simulated welfare gains are largely affected by the tariff aggregation technique over regions and trade policy instruments. Based on this finding we recommend the more widespread application of welfare consistent tariff aggregation in applied modeling and further research on that topic.     

Tariffs,quotas, and voluntary export restraints with endogenous labor supply

This paper develops a two-good, small-country, general equilibrium trade model with endogenous labor supply and wage taxes, and where trade is restricted by a tariff, or an import quota, or VERs. Within this framework we derive (i) the employment and welfare effects of the three types of trade restrictions, (ii) the price effect of an import quota and VERs, and (iii) the shadow price of foreign exchange under each type of trade restriction. The present results are compared to those where (i) factor supplies are fixed, and (ii) perfect international capital mobility exists.     

Smuggling and Bhagwati's Nonequivalence Between Tariffs and Quotas

The authors extend Professor Bhagwati's analysis about the nonequivalence between trade policy instruments when domestic production is monopolized and the terms of trade are endogenous, by allowing for smuggling. They show that the dominance of the ad valorem tariff over the quota is not robust. Tariffication can lower welfare even when the level of illegal imports is quite small. However, tariffication with a specific tariff is always beneficial because the specific tariff dominates the ad valorem tariff and the quota with or without smuggling. Smuggling (or the threat) also tends to lower the second–best tariff/quota, and increases welfare when imports are restricted by a quota, but lowers it under a tariff.     

Regional Blocs and Foreign Direct Investment

The paper examines the impact of the emergence of regional blocs on the patterns of interbloc and intrabloc trade when firms have the option to engage in foreign direct investment (FDI). For exogenously given external tariffs, when firms have the option to engage in FDI, all interbloc trade may cease—complete trade diversion that is replaced by interbloc FDI investment creation. In such an event the volume of world trade declines but this is more than offset by the increase in world output due to direct investment. The paper also investigates the optimal tariff that a trading bloc levies on imports from nonmember countries. The tariffs are restricted by the option to engage in two‐way direct investment; hence, the regional blocs are hampered from mutually harming one another through an escalation in the tariff war. Finally, the formation of two regional blocs enhances the welfare of all countries.     

Country of Origin Labeling (C.O.O.L.): How cool is it?

This paper develops a partial-equilibrium model of a small open-economy trading an unsafe product. The model is used to analyze the welfare effects of trade with and without a country-of-origin labeling (COOL) program. The welfare gains from trade in the absence of COOL are ambiguous, may justify the imposition of a trade ban. Even if a full ban does not improve welfare and some restriction of trade is always welfare-enhancing. Under a tariff regime, more COOL trade is better than less trade. Independently of domestic market power, free trade coupled with a COOL program maximizes national welfare.
