STRATEGIC MANDATORY LABELING OF BIOTECHNOLOGY PRODUCTS IN THE ABSENCE OF QUALITY DIFFERENCE

This article examines the strategic use of mandatory labeling of biotechnology products, such as genetically modified food. A foreign dominant firm produces a biotechnology product and foreign competitive firms produce a conventional one. It is shown that if other trade measures such as tariffs are also available, the government of an importing country may impose mandatory labeling even in the case where there is no quality difference between biotechnology and conventional products. A combination of a discriminatory tariff on the biotechnology product and mandatory labeling shifts rents from the foreign dominant firm to the domestic economy.     

Anti‐dumping duty circumvention through trade rerouting: Evidence from Chinese exporters

We study the evasion of US anti‐dumping duties by some Chinese exporters through trade rerouting via third countries or regions. Using detailed monthly trade data reported by China and the US Customs during the period of 2002–06, we find that US anti‐dumping actions against China lead to a stronger positive correlation between US imports from third countries and Chinese exports to the same third countries. Such a positive correlation is more pronounced for the products subject to anti‐dumping duties (treatment groups) than similar products not subject to these duties (control groups). The evidence is stronger for less‐differentiated products whose certificates of origins are easier to be modified and is stronger for third countries where the rerouting cost is low. These findings are consistent with a trade rerouting story, rather than a simple story of trade diversion (i.e., increase in some third countries' imports from China) and trade deflection (i.e., increase in some third‐country exports to the US). We also rule out other alternative stories, consider prior production in third countries and concurrent anti‐dumping actions against China or third countries, pay a particular attention to the many zero trade flows in the monthly level data and check the robustness to using an alternative control group and quarterly data, etc.     

Bilateral trade wars

The paper constructs a three-country, two-good general equilibrium model to analyze the welfare effects of bilateral trade wars. The presence of a third country (or a number of countries) pursuing free trade policies alters several results based on a two-country framework: Regardless of whether tariffs or quotas are used, bilateral trade wars need not eliminate trade between the two retaliating countries; even a “small” retaliating country can win a bilateral trade war; and quotas can be welfare-superior to tariffs under bilateral retaliation.     

中美欧贸易报复制度的比较研究

WTO体制下,贸易报复是争端解决的最后保障,但WTO争端机制旨在解决成员之间的争端,因此,要赋予私人请求本国政府对另一国家进行贸易报复的权利,仍然需要国内立法.目前,各主要大国都通过国内立法赋予本国国民权利,以请求本国政府对另一国家进行贸易报复,为争端解决的国内程序和国际程序的衔接提供了基础,使得本国国民可以通过国内程序启动WTO的争端解决程序.与美欧相比,我国关于贸易报复的立法和实践经验均不甚丰富,确实需要借鉴较为完备的美欧立法,完善我国的有关法律制度.     

US trade preferences and export performance of developing countries: Evidence from the generalized system of preferences

Preferential market access such as the generalized system of preferences (GSP) is clearly recognized as a way of enabling developing countries export their way out of poverty. It has been a vital feature of industrialized countries' commercial policy for nearly 30 years. This study empirically explores the linkages between US trade preferences under the GSP and beneficiary country exports. Using a large US import database covering over 120 developing countries, the study examines the extent to which GSP influences export performance. The results largely indicate that the GSP has a significant and positive effect on beneficiary exports to US for all country and product groups. A proper understanding of this relationship will help donors and recipients devise appropriate policies to help encourage the growth and diversification of exports that is so vital for developing countries.     

所有权原则、FDI利得与中美贸易差额

在发达国家大量通过FDI参与国际商业活动的背景下,基于所有权原则的贸易收支统计能够捕捉FDI对贸易收支的影响,从而反映出各国参与国际商业活动的实际利得。根据测算,美国自2000年以来外国直接投资净收益约占其贸易赤字的25%~30%。同时基于所有权统计原则调整后发现,中美贸易顺差根源于FDI,这与现有有关中美贸易不平衡的研究结论大相径庭。     

Cones of diversification in a model of international comparative advantage

The hypothesis that all countries belong to a single cone of diversification is often used in studies of international trade. However, contrary to this hypothesis, the range of capital–labour input ratios in US industries does not encompass the range of capital– labour endowment ratios in the world’s economies. Furthermore, among countries with capital–labour endowment ratios below the range of US capital–labour input ratios, wage rates are much lower than in the US. In this paper, the one-cone hypothesis is assessed relative to a two-cone alternative by clustering countries with similar factor proportions, estimating regressions for gross national product and net exports, testing for equality of coefficients, and approximating the posterior odds on one- and two-cone models. Rejecting the one-cone hypothesis, the paper presents estimates of a two-cone model and considers their implications for factor flows and the prospects of emerging market economies.     

Consumer involvement and acceptance of biotechnology in the European Union: a specific focus on Spain and the UK

Biotechnology stands out as a clear‐cut example of an industry where legislation on new technologies has been shown to be linked with public attitudes. Indeed, consumer consultation has played a leading role in the acceptance of genetically modified (GM) food as well as in government policy and legislation. This paper examines the issue of consumer consultation by analysing how public opinion has conditioned the acceptance of GM food in the European Union in general and specifically in Spain and the UK. We draw upon the evidence of two Eurobarometer surveys (46.1 and 52.1) to argue that consumer decision making on new technologies is an information‐dependent factor explaining consumer rejection to non‐transparent introduction of GM food. Individuals feel ill‐prepared to make decisions and rely on trusted information advisors such as consumer organizations. Findings suggest significant information dependency as well as widespread heterogeneity in attitudes towards the applications of biotechnology. Finally, the role played by information channels indicates that consumer participation should precede the adoption of communication policies, as they might need to adapt to the specific cultural characteristics of each country.     

Trade deflection and trade depression

This is the first paper to empirically examine whether a country's use of an import restricting trade policy distorts a foreign country's exports to third markets. We first develop a theoretical model of worldwide trade in which the imposition of antidumping and safeguard tariffs, or “trade remedies,” by one country causes significant distortions in world trade flows. We then empirically test this model by investigating the effect of the United States' use of such import restrictions on Japanese exports of roughly 4800 products into 37 countries between 1992 and 2001. Our estimation yields evidence that US restrictions both deflect and depress Japanese export flows to third countries. Imposition of a US antidumping measure against Japan deflects trade, as the average antidumping duty on Japanese exports leads to a 5-7% increase in Japanese exports of the same product to the average third country market. The imposition of a US antidumping measure against a third country depresses trade, as the average US duty imposed on a third country leads to a 5-19% decrease in Japanese exports of that same product to the average third country's market. We also document the substantial variation in trade deflection and trade depression across different importing countries and exported products.     

Teaching the Linkages Between the International Credit and Foreign Exchange Markets

ABSTRACT

This paper presents a teaching model which provides an analytical framework that encourages students to think about economic events in a global context. It ties the international credit and foreign exchange markets together and shows how international capital flows represent the crucial linkage between them. This model is primarily a teaching tool which illustrates how changes in monetary and fiscal policies in one country, say Japan, impact world interest rates, exchange rates, and trade and capital imbalances for other countries. This approach can also be used to illustrate the impacts of changes in savings and investment behavior by businesses and households, as well as central bank interventions.     

Product attributes and consumer acceptance of nutritionally enhanced genetically modified foods

Using data from a national survey, this study analyses US consumers’ acceptance of genetically modified foods that provide additional nutritional benefits. Using an ordered probit model, this study examines the relation between the willingness to consume genetically modified foods and consumers’ economic, demographic and value attributes. Empirical results suggest that despite having some reservations, especially about the use of biotechnology in animals, American consumers are not decidedly opposed to food biotechnology. Consumers’ economic and demographic variables are only weakly related to their acceptance of food biotechnology, especially when technology involves plant‐to‐plant DNA transfer. However, public trust and confidence in various private and public institutions are significantly related to their acceptance of food biotechnology. Overall, consumer acceptance of bioengineered foods is driven primarily by public perceptions of risks, benefits and safety of these food products.     

Computational Analysis of the Menu of US‐Japan Trade Policies

We have used the Michigan Computable General Equilibrium (CGE) Model of World Production and Trade to calculate the aggregate welfare and sectoral employment effects of the menu of US‐Japan trade policies. The menu of policies encompasses the various preferential US and Japan bilateral and regional free trade agreements (FTAs) negotiated and in process, unilateral removal of existing trade barriers and global (multilateral) free trade. The welfare impacts of the FTAs on the United States and Japan are shown to be rather small in absolute and relative terms. The sectoral employment effects are also generally small but vary across the individual sectors depending on the patterns of the bilateral liberalisation. The welfare effects on the FTA partner countries are mostly positive though generally small, but there are some indications of potentially disruptive employment shifts in some partner countries. There are indications of trade diversion and detrimental welfare effects on non‐member countries for some of the FTAs analysed. In comparison to the welfare gains from the US and Japan bilateral FTAs, the gains from both unilateral trade liberalisation by the United States, Japan and the FTA partners, and from global (multilateral) free trade are shown to be rather substantial and more uniformly positive for all countries in the global trading system. The US and Japan FTAs are based on ‘hub’ and ‘spoke’ arrangements. We show that the spokes emanate out in different and often overlapping directions, suggesting that the complex of bilateral FTAs may create distortions of the global trading system.     

Education bias of trade liberalization and wage inequality in developing countries

The aim of this article is to examine the impact of increased trade on wage inequality in developing countries, and whether a higher human capital stock moderates this effect. We look at the skilled–unskilled wage differential. When better educated societies open up their economies, increased trade is likely to induce less inequality on impact because the supply of skills better matches demand. But greater international exposure also brings about technological diffusion, further raising skilled labour demand. This may raise wage inequality, in contrast to the initial egalitarian level effect of human capital. We attempt to measure these two opposing forces. We also employ a broad set of indicators to measure trade liberalization policies as well as general openness, which is an outcome, and not a policy variable. We further examine what type of education most reduces inequality. Our findings suggest that countries with a higher level of initial human capital do well on the inequality front, but human capital which accrues through the trade liberalization channel has inegalitarian effects. Our results also have implications for the speed at which trade policies are liberalized, the implication being that better educated nations should liberalize faster.     

US–China rivalry: The macro policy choices

Stylised representations of recent US and Chinese tax reforms, tariffs against imports and alternative Chinese monetary targeting are examined using a calibrated global macro model that embodies both trade and financial interdependencies. For both countries, unilateral capital tax relief and bilateral tariffs are shown to be ‘beggar thy neighbor’ policies. As large economies, both enjoy ‘optimal tariffs’, even bilaterally, though net outcomes are shown to depend on the allocation of revenues. Bilateral tariffs are most advantageous for the US if the additional revenue finances indirect tax relief. Once US bilateral tariffs are imposed, China is a net loser irrespective of its policy response, though a currency float is shown to cushion the effects on its GDP in the short run. Equilibria in normal form non-cooperative tariff games have the US imposing tariffs while China liberalises.     

The effects of bilateral attitudes on imports

Research based on the gravity model has shown that non-economic factors affect international trade, and recent studies have shown that people's perception affects economic exchange. In this study, we explore the effects of attitudes on bilateral trade. Using survey data from the Pew Research Center's Global Attitudes Projects for 68 countries from 2002 to 2015, we find that a more favourable attitude of a country towards another country will increase the former country's imports from the latter. The result is robust to an endogeneity check, to different measures of attitudes and to different estimation methods. However, heterogeneity is observed across different types of goods and countries. The result holds for trade in intermediate and consumer goods, but the effects are not statistically significant for capital goods. The effects are statistically significant for bilateral trade between different country groups, except for high-income countries' imports from non-high-income countries.     

自由贸易及跨界污染背景下的国际环境政策协调

文章构建了一个考虑跨界污染损害的福利函数,推导出自由贸易背景下某国的最优污染税,并与世界福利最大化时的最优污染税进行比较,以说明国家间环境政策协调的必要性。文章考虑了四种情况,分析结果表明,只有在该国为小国且污染不跨界时不需要国际协调;当该国为大国或者污染跨界时,单个国家的独立行为通常不会产生合意的世界福利水平,此时需要国际协调以实现世界福利最大化。大国的污染政策具有贸易条件效应,因而出口国有设定过高污染税的激励,而进口国则会设定过低的污染税,双方都寻求转变贸易条件以有利于本方。而污染跨界时单个国家通常会有"搭便车"的激励,此时会实施较为宽松的环境政策。     

The World Trade Organisation's Doha Cotton Initiative: A Tale of Two Issues

Four West African nations have demanded that the WTO's Doha Development Agenda include a Cotton Initiative that involves two issues: cutting cotton subsidies and tariffs, and assisting farm productivity growth in Africa. This paper provides estimates of the potential economic impacts of (a) complete or partial removal of cotton subsidies and import tariffs globally and (b) cotton productivity growth through the adoption of genetically modified (GM) cotton varieties. Use is made of the GTAP database and global economic model to address both these issues. On Doha, our results confirm that for cotton – unlike for other agricultural subsidies and tariffs – it is subsidy reductions rather than tariff cuts that would make by far the largest impact. For Sub‐Saharan Africa the potential gains are huge relative to the effects on that region of reforming other merchandise trade policies. And they could be more than doubled if that reform provided the cash for farmers to take advantage of the biotechnology revolution and adopt GM cotton varieties. But those potential gains, and the affordability of switching to costly GM seed, depend crucially on the extent to which high‐income countries are willing to lower domestic support to their cotton farmers.     

Trade,scale or social capital? Technological progress in poor and rich countries

Endogenous growth theory suggests scale and trade as the determinants of total factor productivity (TFP) growth. The literature on social capital suggests that the levels of trust and participation in societies may affect cooperation and innovation. While there is evidence of the role of trade and inconclusive evidence on the role of social capital, previous studies have generally omitted two factors, out of the three mentioned, used small sample sizes and emphasized economic growth rather than technological progress. Our study addresses these shortcomings. We find robust evidence of the role of trade in fostering technological progress which is invariant to TFP proxies and independent of the debate on measuring TFP. Moreover, there is no clear role for scale, and a country rate of TFP growth seems to increase the most the more the country trades with dynamic economies that are different from. We uncover a positive effect of social capital, which is more significant in richer countries, suggesting that other characteristics, such as institutional quality, may be complementary to social capital. The paper's results are robust to different specification and estimation methods.     

US trade policy in an unbalanced world economy

Both the national as well as the international debate on US trade policy are overshadowed, and strongly influenced, by the large external inbalances of major trading nations. What do these disequilibria mean for US trade policy? Moreover, is the USA losing comparative advantage in agriculture and high-technology manufacturing? Do industrial policies in other countries distort American trade?
