Gains from trade in used goods: Evidence from automobiles

I investigate the welfare effects of trade liberalization by exploiting a natural policy experiment in the economy of Cyprus. A 1993 law relaxed import restrictions on used vehicles and enabled the importation of second-hand Japanese automobiles into the country. This led to a dramatic shift of consumer purchases from new to used cars and a substantial expansion of the overall market. Welfare gains computed from a structural demand system average $2000 per purchaser per year over a four-year period after the policy change. The findings are suggestive of the potential for substantial gains from liberalizing trade in used goods.     

源于比较优势的贸易所得:来自中国的证据

本文根据新古典贸易模型中的贸易所得的理论定义,对测算源于比较优势的贸易所得的基本方法及其理论基础进行了回顾和分析,在此基础上利用进出口额的现值与贸易所得的估算值之间的格兰杰逻辑关系,对中国源于比较优势的贸易所得进行了测算。本文的测算结果表明,中国源于比较优势的贸易所得的最大估算值约为GDP的5%。从比较的角度考察,这一结论的政策含义是,主要依赖劳动力资源或不可再生自然资源比较优势的贸易模式已不具备可持续发展性,建立基于动态比较优势的对外贸易战略应成为包括中国在内的发展中国家的贸易政策选择。     

On the European Responsibility in the Agricultural Multilateral Trade Negotiations: Modelling the Impacts of the Common Agricultural Policy

The present round of multilateral trade negotiations is still deadlocked over agricultural trade. The European Union (EU) is urged by its trading partners to open its agricultural markets. Economic evaluations of trade liberalisation scenarios unanimously conclude that a substantial opening of agricultural markets is required for a successful (welfare‐improving) Doha Round. In this paper, we perform new evaluations to identify precisely the contributions of the European farm policy and to examine the robustness of these evaluations in the representation of this complex policy. Using the same specifications as in major previous studies, our first simulations show that the EU has a major responsibility in delivering significant gains to the developing countries. On the other hand, when we conduct the same experiments with a more relevant calibration and modelling of the European farm policy instruments, the gains that these developing countries may reap from the EU liberalisation are considerably reduced. Accordingly the current charge against the EU is simply inopportune.     

开放条件下贸易利益内涵的界定及其相关理论评述

长期以来,参与国际分工与贸易的各国是否能从国际贸易中获得利益这一问题,一直是理论界争论的焦点,因此,本文从狭义的贸易利益与广义的贸易利益,真实的贸易利益与潜在的贸易利益,贸易利益与地区经济一体化,贸易利益与不完全竞争、规模报酬递增四个角度作了一些评述。本文认为,只有在一定的条件之下,一国才可以从开放的国际贸易中获得贸易利益,最终实现一国经济持续增长的目标,如政府在开放经济条件下采取适当的贸易政策、在开放贸易情况下补偿受损人群的利益、参与区域经济一体化等。     

The Payoff to America from Globalisation

This article summarizes the economic payoff to the United States from its postwar trade opening and estimates the potential future gains from more opening going forward. To quantify these gains, we survey different methodologies and estimates. We find that trade opening since World War II has added between $800 billion to $1.4 trillion to the US economy, or about $7,000 to $13,000 per household. More speculative estimates of the potential additional gains from removing the rest of US trade barriers range from $400 billion to $1.3 trillion, or about $4,000 to $12,000 per household. Since trade opening permanently raises national income, these gains are enjoyed annually. Trade opening inevitably entails adjustment costs. We estimate that the lifetime cost of all worker dislocations that have been triggered by expanded trade in the United States could be as high as $54 billion, although probably less. The permanent gains from past and potential liberalization easily swamp the modest sums necessary to alleviate the temporary pains of adjustment. In the future as in the past, free trade can significantly raise income – and quality of life – in America.     

Non-competitive imports and gains from trade

The paper argues for the explicit inclusion in international trade models of goods which cannot be produced in the importing country. Non-competitive goods require a product-requisite factor which is not universally available. International trade in these goods generates much greater per-unit gains from trade than trade in ordinary goods which can be produced in both (all) countries. Omission of these goods from models of international trade leads to the possibility of a gross underestimation of the difference between autarkic and with-trade income levels. The omission of these goods also neglects some dimensions of policy which are important in the real world, such as sanctions.     

Trade policy, trade volumes and plant-level productivity in Colombian manufacturing industries

This paper explores a period of substantial variation in trade policy across industries in Colombia (1977-1991) to examine whether increased exposure to foreign competition generates productivity gains for manufacturing plants. Using an estimation methodology that addresses the shortcomings of previous studies, we find a strong positive impact of tariff liberalization on plant productivity, even after controlling for plant and industry heterogeneity, real exchange rates, and cyclical effects. The impact of liberalization is stronger for larger plants and plants in less competitive industries. Our findings are not driven by the endogeneity of protection. Similar results are obtained when using effective rates of protection and import penetration ratios as measures of protection. Productivity gains under trade liberalization are linked to increases in intermediate inputs' imports, skill intensity, and machinery investments, and to output reallocations from less to more productive plants.     

Trade Policy Issues in a Small African Economy: The Trade Policy Review of The Gambia 2004

The Gambia displays many of the classic characteristics of a small open economy, with the vulnerabilities that implies. The sum of its imports and exports are around 100 per cent of GDP, with a limited number of export commodities and a wide variety of imports, including some key staple foods. The Trade Policy Review of The Gambia 2004 provides a very helpful review and assessment of current trade patterns and policies. The latter rely predominantly on import and export taxes. While quite substantial trade reform measures have been implemented recently, these have led to only a very small reduction in the average tariff rate, and trade policy displays a substantial anti‐export bias. Other important issues highlighted by the Trade Policy Review include serious capacity constraints relating to trade policy, and a failure to discuss connections between trade policy and growth and poverty reduction – again common characteristics of many small economies.     

Trade liberalization and informality nexus: Evidence from Pakistan

This study investigates the impact of trade openness on informal sector employment during the drastic 1988s trade reforms of Pakistan. It is generally perceived that increased external competition in less developed countries results in as an expansion in informal sector, which has less compliance with labor market regulations. Using micro-level data of Pakistan, we study the adjustments in the employment of informal sector due to trade openness. We find that informality and trade openness are associated. In Pakistan, trade reforms have given rise to employment in the informal sector. Our findings are robust to different trade-related measures. A substantial flexibility in labor market is required to benefit from the gains of liberalization.     

What's the Point of Reciprocal Trade Negotiations? Exports,Imports, and Gains from Trade

This paper explains why trade‐policy makers may prefer reciprocal trade negotiations (RTN) to unilateral tariff reductions (UTR) for economic reasons. It answers puzzles like ‘Why WTO reciprocity?’ and strengthens the unnecessarily weak case made for the WTO by those who downplay or dismiss benefits from foreign tariff reductions (FTR). RTN is superior to UTR because it provides economic benefits that UTR cannot – namely, FTR benefits which are clearer than potentially important UTR benefits: Whereas each policy offers efficiency gains, any terms‐of‐trade effect of UTR generally detracts from these gains, while any terms‐of‐trade effect of FTR is typically beneficial (especially for a small price‐taking country) with this benefit augmenting FTR's efficiency gains. Moreover, benefits from reductions in foreign barriers may come from several sources; they are not solely the result of terms‐of‐trade improvement – or economies of scale (the two benefits already noted in the literature, though often dismissed). For example, with foreign NTB elimination, possible home benefits are shown even with rising costs and terms‐of‐trade deterioration. RTN is also superior to UTR because, by eliminating protection in either NTB or tariff form, RTN provides an escape from not only a terms‐of‐trade prisoners’ dilemma, but many other previously unrecognised prisoners’ dilemmas, including one in international rent transfers, and several others with no economies‐of‐scale or terms‐of‐trade motivation. Of course, if superior RTN is not an option, UTR may well be desirable. If reciprocity is an option, but only in a narrower CU or FTA form, such reciprocity may still be superior to UTR, or it may be inferior; theory cannot unambiguously rank these.     

Unemployment and Trade Liberalisation

In contrast to the focus of the public debate over trade liberalisation on job losses there is a widespread view among economists that unemployment and trade issues should be considered separately. This view cannot be justified theoretically, and ignores the growing number of general equilibrium trade models with unemployment. In a simple model with an exogenous wage floor, trade liberalisation can lead to either gains or losses depending on the production technology, severity of the factor market distortion, factor intensities of the industries and conditions in trading partners. Definite results can be derived about gains from liberalising trade with lower wage floors, about relative abundance of the unemployed factor dampening losses when trade is liberalised, and about gains when the good which uses the unemployed factor is exported. The theoretical models are then linked to the policy modelling literature, using the example of recent Australian controversies over liberalisation of trade in automobiles and textiles. It is argued that trade liberalisation would be better advanced by including endogenous employment in trade policy simulation exercises and by discussing employment effects rather than brushing them aside as temporary adjustment problems or regional difficulties.     

Who in Brazil Will Gain from Global Trade Reforms?

The potential impacts of multilateral trade liberalisation on developing countries are the subject of numerous controversies. One particular concern is that Brazil, a major agricultural exporter and a country with one of the world's most unequal income distributions, will reap a substantial share of the potential benefits to developing countries from agricultural trade reform, and that most of those benefits will go to large‐scale commercial farmers rather than to the country's smallholders. This claim is explored via a global general equilibrium model and a national model of Brazil containing multiple agricultural and non‐agricultural households. Brazil is found to account for nearly one‐half of all the benefits to developing countries deriving from global agricultural trade reform. These gains are associated with improvements in the welfare of each group and a lower incidence of poverty. Large‐scale producers gain more than smallholders as they tend to be relatively specialised in export products, but there are important gains to agricultural employees, who are relatively poor, and to urban households, who benefit from the expansion of the agro‐food sector. Overall, there is no discernible impact on income inequality, and no evidence that the gains to commercial farmers occur at the expense of poorer households.

Multilateral,Regional and Bilateral Trade‐Policy Options for the United States and Japan

We have used the Michigan Model of World Production and Trade to simulate the economic effects on the United States, Japan, and other major trading countries/regions of the Doha Round of WTO multilateral trade negotiations and a variety of regional/bilateral free trade agreements (FTAs) involving the United States and Japan. We estimate that an assumed reduction of post‐Uruguay Round tariffs and other barriers on agricultural and industrial products and services by 33 per cent in the Doha Round would increase world welfare by $686.4 billion, with gains of $164.0 billion for the United States, $132.6 billion for Japan, and significant gains for all other industrialised and developing countries/regions. If there were global free trade with all post‐Uruguay Round trade barriers completely removed, world welfare would increase by $2.1 trillion, with gains of $497.0 billion (5.5 per cent of GNP) for the United States and $401.9 billion (6.2 per cent of GNP) for Japan. Regional agreements such as an APEC FTA, an ASEAN Plus 3 FTA, and a Western Hemisphere FTA would increase global and member country welfare but much less so than the Doha multilateral trade round would. Separate bilateral FTAs involving Japan with Singapore, Mexico, Chile and Korea, and the United States with Chile, Singapore and Korea would have positive, though generally small, welfare effects on the partner countries, but potentially disruptive sectoral employment shifts in some countries. There would be trade diversion and detrimental welfare effects on some non‐member countries for both the regional and bilateral FTAs analysed. The welfare gains from multilateral trade liberalisation are therefore considerably greater than the gains from preferential trading arrangements and more uniformly positive for all countries.     

Gains from trade and the size of a country

Who gains more from trade—the small country or the large country? In the standard Ricardo–Mill two-country model the small country reaps all the gains from trade and the large country (the rest of the world) gains nothing. The present paper considers this question of the distribution of gains from trade between the large country and the small country in terms of a multicountry framework. In this altered setting it is shown that the distribution of gains will generally be independent of the size of the country so long as there is universal free trade. With trade restrictions the presumption, if there is any, would rather be in favour of the large country gaining more than the small country.     

Free trade,protection and economic development

Central to the following discussion is the assertion that a foreign trade policy which maximizes the static efficiency gains from trade may result in reduced dynamic or X-efficiency and thus impair a developing country’s development potential. The dominant view of the relation between international specialization and economic development is summarized. An alternative line of argument is presented in outline. Finally, the implications for development policy are sketched.

Does International Trade Cause Economic Growth? A Survey

This study surveys the literature on the relationship between international trade and economic growth, and succinctly reviews the role of GATT/WTO in fostering free trade. Most studies support the gains of trade and recognise the substantive contributions of GATT/WTO in fostering free trade; the evidence is, however, not ubiquitously unambiguous. The macroeconomic evidence provides a dominant support for the positive and significant effects of trade on output and growth, while the microeconomic evidence lends larger support to the exogenous effects of productivity on trade, as compared to the effects of trade on productivity. The GATT/WTO remains surrounded by barriers to trade and avowed preferences for preferential trade agreements. The strength of the argument for the gains of trade needs to be evaluated in juxtaposition with several methodological and measurement issues that surround the trade‐growth empirics. Most studies focus on partial equilibrium analysis of trade policy and ignore the general equilibrium aspects of macroeconomic policy. It is difficult to disentangle the effects of trade policies from those of other macroeconomic policies and unequivocally interpret the observed correlations between trade policies and economic growth. Trade is one of the several catalysts of productivity and growth and hence its contribution is contingent on its weight in economic activity.     

Privatisation and the unusual case of Belarusian accession to the WTO

The accession negotiations of Belarus to the WTO are unusual since, due to its obligations in the Eurasian Economic Union, WTO accession is not expected to impact its tariffs or formerly substantial trade‐distorting agricultural subsidies. Nonetheless, we estimate that WTO accession will increase welfare by 9.9% of consumption in Belarus. We show that inclusion of: (i) foreign direct investment; (ii) reduction in non‐discriminatory barriers against services providers; and (iii) our model with imperfect competition and endogenous productivity effects together produce estimated gains eleven times larger than a model of perfect competition with only cross‐border trade in services. Our analysis is enabled by our production of a data set on both discriminatory and non‐discriminatory barriers in services and their ad valorem equivalents. Based on a new data set on labour productivity by sector and type of ownership, in our central model, we estimate that privatisation will increase welfare by 35.8% of consumption. We find substantial variance in the estimated gains from privatisation depending on model assumptions, but all the estimates of the impacts of privatisation indicate substantial welfare gains.     

Some Aspects of Trade between Australia and Pacific Island Countries

Australia and Pacific Island countries (PICs) have maintained an ongoing trade and economic relationship for several years. The determinants of trade between Australia and PICs are examined using a gravity model by utilising time‐series cross‐country data for the period 1981 to 2005. The empirical findings indicate that imports by PIC from Australia are significantly determined by PICs’ population and their per capita GDP. The results also suggest that PICs’ exports are significantly determined by PICs and Australia's population, PICs’ infrastructure (telecommunications) and the distance to Australia. Consistent with the findings of other studies using the gravity model, distance is found to be a friction to PICs’ exports to Australia. While this study identifies factors influencing PICs’ trade with Australia, a more substantial issue for the governments and trade policy makers in PICs is to look into the generally disappointing long‐term trade performance. From a policy perspective, PICs would need to seriously look at increasing their export potential.
