International Trade with a Public Intermediate Good and the Gains from Trade*

This paper presents a one‐primary factor, two‐consumer good, and two‐country model of international trade where each country’s government supplies a country‐specific public intermediate good so as to attain efficient production. By introducing the Marshallian adjustment process, it is demonstrated that the country with larger factor endowment exports the good whose productivity is more sensitive to the public intermediate good. Our normative analysis of free trade shows the following results. First, at least one country gains from trade. Secondly, if a country incompletely specializes in the trading equilibrium, the country necessarily loses from trade.     

International trade between consumer and conservationist countries

We consider trade between a ‘consumer’ country with an open access renewable resource and a ‘conservationist’ country that regulates resource harvesting to maximize domestic steady-state utility. In what we call the mild overuse case, the consumer country exports the resource good and suffers steady-state losses from trade, as suggested by the conventional wisdom that weak resource management standards confer a competitive advantage on domestic firms in the resource sector but cause welfare losses. Strikingly, however, when the resource stock is most in jeopardy, the conservationist country exports the resource good in steady state and both countries experience gains from trade.     

Trade and Industrial Policies with Heterogeneous Firms: The Role of Country Asymmetries

This paper explores the role of country asymmetries for trade and industrial policies with heterogeneous firms. The analysis delivers a number of novel results. First, trade policies, infrastructure policies and industrial policies which improve the business conditions in one country have negative productivity and welfare effects on the trading partner. Second, symmetric trade liberalization is immiserizing for a trading partner whose business conditions are inferior. Third, there are gains from trade even for a country whose monopolistically competitive sector with heterogeneous firms is wiped out by switching from autarky to trade.     

人民币汇率对我国对外贸易结构的影响分析

作者利用贸易特定化系数衡量了我国2005年7月21日人民币汇率形成机制改革之后的对外贸易结构，结果显示随着人民币汇率的爬行式缓慢升值，我国大部分资源密集型商品的净出口减少，劳动密集型商品和资本、技术密集型商品的净出口增加，竞争力增强，进出口商品的贸易结构得到优化。因此，进一步完善人民币汇率形成机制，推动人民币汇率稳步升值对我国进出口商品贸易结构是长期利好的。     

Does Ease of Communication Increase Trade? Commonality of Language and Bilateral Trade

Gravity model explanations of trade volumes frequently include dummy variables to account for the commonality of language among trading partners. In this paper we use a data set for the number of people in a country who speak English as a first language or English as a second language (Crystal, 1997) as an indicator of the ease with which trade with the United States occurs. Controlling for commodity fixed effects we use SITC three digit industry data centred on 1995 United States bilateral trade with 33 countries to determine the effect of the degree of language commonality on bilateral trade. Both English as a first language and English as a second language are found to be less important for exports than for imports. This is true for all three digit industries as well as when the specific industry groups identified in Rauch (1999) are considered.     

Randomized double auctions: gains from trade,trader roles,and price discovery

Experimental double-auction commodity markets are known to exhibit robust convergence to competitive equilibria under stable or cyclical supply and demand conditions, but little is known about their performance in truly random environments. We provide a comprehensive study of double auctions in a stochastic setting where the equilibrium prices, trading volumes and gains from trade are highly variable across periods, and with commodity traders who may buy or sell their goods depending on market conditions and their individual outcomes. We find that performance in this stochastic environment is sensitive to underlying market conditions. Efficiency is higher and convergence to the competitive equilibrium stronger when the potential gains from trade are high and when the equilibrium spans a wide range of quantities, implying a large number of marginal trades. Speculative re-trading is prevalent, especially among those who have little to gain under equilibrium pricing. Those with the largest expected gains typically earn far less than predicted, while those with little or no predicted earnings gain modestly from speculation, leading to some redistribution of gains from high to low expected earners. Excessive trading volumes are associated with negative efficiencies in markets with low gains from trade, but not in the high-gains markets, where zero-sum trading and re-trading appear to enforce efficiency and near-equilibrium pricing. Buyers earn more relative to their competitive equilibrium benchmark than sellers do. Introducing trader specialization leads to fewer trading errors and higher market efficiency, but it does not eliminate zero-sum trading and re-trading.

     

Trade Liberalization in Egypt

A computable general equilibrium model of Egypt is developed to analyze proposed reforms in its trade policies, including a partnership agreement with the European Union. The model has multiple trading regions and allows for administrative trade barriers and tariffs. The paper reports computations of the revenue impacts of trade liberalization and the required changes in distortionary commodity taxes to maintain a fixed real government budget. Egypt's greatest potential gains come from removing its administrative trade barriers while adopting globally free trade. The partnership agreement with the EU could lower or raise Egypt's welfare, depending on prior trade reform.     

Why Do the Gains from Trade Reform Vary Between Countries?

This paper assesses, both theoretically and empirically, the determinants of differential gains from trade policy reform across countries. The theoretical model shows that asymmetrical features of the world economy, including the relative size of the differentiated products sector in each country, the dominance of domestic markets by indigenous producers, trade costs, and the relative importance of exports, all play an important role. Results from a multi-region computable general equilibrium model substantiate the proposition that the initial pattern of asymmetry is relatively more important than scale and varietal effects, despite the fact that the latter have received more attention in the literature.     

The J-curve: evidence from commodity trade between US and China

In testing the short-run (J-curve effect) and the long-run effects of currency depreciation on the trade balance many researchers have used either trade data between one country and the rest of the world or between one country and another trading partner. Both groups are said to suffer from aggregation bias. To reduce the bias, in this article we consider trade data between one country (the US) and her trading partner (China) disaggregated by commodity. We use imports and exports of 88 industries (2-digit and 3-digit classifications) and cointegration analysis to show that the trade balance of at least 34 of the industries react favourably to real depreciation of the dollar. The J-curve effect is detected in 22 industries. Furthermore, most of these industries that are sensitive to currency depreciation are durable commodity groupings.     

Joining the World Trade Organization: What is the Impact?

Research has called into question the impact of the World Trade Organization (WTO) on trade. This research, however, has been called into question on both modeling grounds for and failing to utilize comprehensive fixed effects. Others have found that when these factors are accounted for, imports rise by significant amounts. This paper seeks to reconcile these findings. I find that the WTO has a larger, though uneven, impact on exports than imports. The results indicate that the WTO frequently causes imports and exports to move in opposite directions negating any increase in overall trade. The regressions with and without fixed country effects generally demonstrate pattern consistency for generalized results that are robust to change. Owing to the finding that imports rise modestly or even fall without country effects while exports rise, the results imply that countries may not be as interested in liberalizing trade as selling to the world.     

贸易自由化与增加值贸易*——WTO对中国出口的真实影响

国际贸易的中间品贸易的兴起,使传统关境贸易统计无法准确衡量全球价值链下一国的实际贸易利得。本文基于增加值贸易视角重新评估加入WTO对于中国出口的真实影响,以及关境统计下WTO贸易促进作用与真实状况的偏离。基于引力模型的实证结果表明：（1）总体上,中国加入WTO显著促进其增加值出口,但关境统计明显高估了WTO贸易促进作用。（2）分行业看,WTO对中国增加值出口的贸易促进作用存在显著的行业差异：加入WTO显著地促进了中国非制造业工业、制造业和服务业增加值出口,却抑制了中国农林牧渔业的增加值出口。（3）进一步研究发现,关境统计数据对于WTO贸易促进作用的高估问题仅存在于制造业,对于农林牧渔业等其他三个行业反而存在低估问题。     

Trade and Global Income Inequality with Frictional Labor Markets: A Lesson from the Canada–US Free Trade Agreement

This paper develops a two-country trade model with frictional labor market structures to investigate the link between increased openness to trade and cross-country income inequality. Calibrated to US–Canadian data, the model simulation results show that the Canada–US Free Trade Agreement benefited Canada, the country with relatively higher capital intensity, more due to its capacity to flexibly expand in response to an increase in product demand. The results from counterfactual experiments indicate that increased capital intensity in the US is expected to increase gains from trade in both countries while making the distribution of gains less unequal.     

贸易统计差异与中美贸易平衡问题

本文研究发现(1)中美进出口计价方式不同和运输时滞导致双边贸易统计数据存在差异是自然的。(2)参照剔除香港转口毛利后中美贸易新估计值,1995—2003年美国对华出口低估年均在24%以上,从华进口高估年均在35%以上,而中国对美出口低估年均在20%以上,从美进口相对没变。(3)考虑服务贸易后,美中商品与服务贸易逆差估计值与中国对美贸易顺差新估计值已相当接近。上述结果得到IMF数据的证实。(4)外商在华直接投资增加会造成中国对美出口增加、对美贸易顺差增加。依据中美两国月度数据计量的结论是相一致的。这一结果证实中美贸易平衡问题已超越中美两国贸易范围而成为外商在华直接投资所引致的贸易逆差转移问题。剔除外资企业进出口贡献及贸易统计差异后,中国对美贸易估计值已非常趋近于美国对华贸易估计值。     

Marshall's Scissors: The Gains and Losses from Trade

In a Ricardian two‐factor endowment model with Cobb–Douglas tastes and many goods, this paper describesthe interaction of the demand and supply sides to determine the gains and losses from trade. If the abundant factor has a sufficiently rich profile of comparative advantages, trade causesthe proportionate gain to the abundant factor to be smaller than the proportionate loss to the scarce factor. However, if the abundant factor has sufficiently skewed comparative advantages toward the best goods, then the opposite will hold. Some examples suggest that these patterns may have something to do with the selection of trade regimes. In the usual one‐factor Ricardian model the gains from trade to a country are enhanced by higher demand shares for imports, but such gains from trade from imports to a country is not the case in a factor endowment model.     

虚拟水、虚拟水贸易理论研究综述

相对于水价和用水技术能够提高水资源在当地的配置效率,虚拟水贸易则可以提高水资源在全球范围内的配置效率。虚拟水从水资源生产率较高的国家流向水资源较低的国家意味着在全球层次上水资源的节约。因此,国家之间、洲际之间虚拟水贸易被看作提高全球水资源利用效率和缺水国家获得水安全的一个有力工具。     

Gains From Trade for Nonmaterialists,Environmentalists, and the Overworked

The author proposes an alternative to the traditional definition of the gains from international trade and, hence, an alternative defense of free trade. Rather than showing that free trade allows a country to consume more of all final goods, the author's approach shows that free trade allows a country to consume the same basket of final goods that it would consume in autarchy but at a reduced cost measured in terms of foregone productive resources. Thus, free trade gives a country the option to maintain the same material standard of living that it would have enjoyed in autarchy while enjoying more leisure and using fewer natural resources in production.     

Trade liberalization and trade performance of environmental goods: evidence from Asia-Pacific economic cooperation members

In this article, we study the impact of trade liberalization, including reductions in both tariff and nontariff trade barriers, on environmental goods (EGs) exports. Using bilateral trade data from 20 Asia-Pacific Economic Cooperation members, we find that tariff reduction in an exporting country has a larger positive impact on its exports of EGs than tariff reduction in an importing country. Our results also show that a lower nontariff barrier in an importing country increases its imports of EGs. A considerable amount of heterogeneity also exists in subsample results based on countries’ income levels.     

Technology for Sale

Free trade in commodities typically leads to gains for all participating countries. These gains can be augmented by trade in productive factors if returns differ between countries. But such trade would not exhaust potential gains if technological knowledge, not embedded in productive factors, differs between countries. Using a Ricardian model this paper shows how a country which has an absolute advantage based on technology in both commodities in a two-commodity world can gain by selling, giving, or even bribing the other country into using the advanced technology in the other country's export sector. If each country has an absolute advantage in the single commodity it produces, an exchange of technology for the other commodity can nonetheless lead to extra gains for both countries.     

AUSTRALIAN COMMODITY EXPORT PASS-THROUGH AND FEEDBACK CAUSALITY FROM COMMODITY PRICES TO THE EXCHANGE RATE

Commodity export pass-through is examined for Australia in an attempt to determine whether Australia is a price-taker in its commodity export trade. This is undertaken for seven categories of Australia's main commodity good exports. We also determine if there is feedback causality from particular world commodity prices back to the exchange rate as is often hypothesised for commodity good intensive exporting countries. It is found that Australian commodity good export pass-through is complete for the goods which are relatively less important in its export trade but is incomplete (although high) for the goods which are most important in its export trade. There is significant feedback causality to the exchange rate from the world price of coal and wheat, two of Australia's most important commodity good exports over the 1980s and early 1990s.     

Analysing Comparative Advantage and Competitiveness: An Application to Australia's Textile and Clothing Industries

Australia's comparative advantage and competitiveness in textile and clothing (TAC) industries are analysed, using Balassa's revealed comparative advantage index and Vollrath's measures of competitiveness. The analysis based on Balassa's indices shows that Australia has a strong comparative disadvantage in textiles and clothing as aggregate commodity groups, but there is comparative advantage in sub–categories of 'special textile products', 'floor coverage, tapestry etc', and 'fur clothing'. The analysis based on Vollrath's indices shows that Australia is not competitive in the world market with respect to aggregate commodity groups of textiles and clothing. Grubel–Loyd index of intra–industry trade was calculated for seven categories of textiles and two categories of clothing. The results show a rising trend in intra–industry trade in some of these categories of TAC products, implying that Australia increasingly exports and imports differentiated TAC products. Australian TAC industries may look to further promote exports of their products in the global market through increased product differentiation and improved quality and design.
