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.     

Firm‐Level Evidence for the Language Investment Effect on SME Exporters

Both analysis of international trade and the knowledge resource theory of the firm imply that language skills should play a vital role in exporting. This may be apparent to large multinationals with sites in many different linguistic locations, but we show it is less obvious to smaller companies. With data on the language used by each of a large sample of European small‐ and medium‐sized enterprises in their export markets, we test and estimate the effects of language assets on language performance in export markets and on export sales. Controlling for the possibility that language skills may be acquired by exporting, we find a very substantial export return to linguistic expertise, indicative of unexploited gains from investment in languages. There is also evidence of greater under‐investment in language skills in English‐speaking Europe.     

Internet Technology and the Extensive Margin of Trade: Evidence from eBay in Emerging Economies

Online platforms such as eBay offer technologies that make it easier for firms to export. This paper dissects a new firm‐level dataset that covers sales made through eBay by sellers based in 21 emerging economies to provide a new lens through which to look at the effect of trade costs on the extensive margin of trade. Comparing eBay sellers with “offline” firm‐level data from the World Bank's Exporter Dynamics Database allows us to test whether the observed trade patterns on eBay fit with the trade‐liberalization predictions of heterogeneous‐firm models. We find that eBay firms export to more destinations, suggesting low destination‐specific fixed costs on eBay. We then show that the distribution of export destinations across eBay sellers is well approximated by a balls‐and‐bins model of frictionless trade, suggesting eBay indeed lowers fixed export costs. Finally, we compare the gravity of eBay with that of offline trade and find geographic distance, languages, and trade agreements to matter less for online trade.     

Exports and innovation: the role of heterogeneity in exports

This paper examines whether and how heterogeneity in exports affects firms’ innovations in China. Using comprehensive transaction-level trade data from China Customs to construct various dimensional measures exports, empirical results obtained from a matched firm-transaction panel data find that exports overall have a positive impact on promoting innovations in terms of R&D and new product sales. The innovation-enhancing effect of exports depends on the heterogeneity in exports. Firms with greater varieties of exports, more market diversification, and higher export quality are associated with a higher R&D propensity and more new product sales, while process exports are found a negative association with innovations.     

Beyond the average effects: The distributional impacts of export promotion programs in developing countries

Do all exporters benefit the same from export promotion programs? Surprisingly, no matter how obvious this question may a priori be when thinking of the effectiveness of these programs, there is virtually no empirical evidence on how they affect export performance in different parts of the distribution of export outcomes. This paper aims at filling this gap in the literature. We assess the distributional impacts of trade promotion activities performing efficient semiparametric quantile treatment effect estimation on assistance, total sales, and highly disaggregated export data for the whole population of Chilean exporters over the 2002-2006 period. We find that these activities have indeed heterogeneous effects over the distribution of export performance, along both the extensive and intensive margins. In particular, smaller firms as measured by their total exports seem to benefit more from export promotion actions.

Interrelationship among foreign presence,domestic sales and export intensity in Chinese manufacturing industries

Using panel data on six Chinese manufacturing industries over the period 2005–2007, this article explores the interrelationship among foreign presence, domestic sales and export intensity of local firms. We find that the domestic sales and exports are complementary for local firms in China’s pharmaceutical industry, whereas in the case of the textile, transportation equipment, beverage, communication equipment and general equipment manufacturing industries, domestic sales and exports are substitutes. An increase in the average domestic sales increases foreign presence in all industries. The same applies to an increase in the average export intensity. An increase in the level of competition in China’s textile industry increases the export intensity as well as domestic sales of local textile firms. However, an increase in the level of competition in the pharmaceutical industry leads to a very large decrease in export intensity of local pharmaceutical firms. In the case of China’s transportation equipment manufacturing industry, an increase in the level of competition decreases domestic sales of local firms. Furthermore, an increase in the firm size increases domestic sales of Chinese firms in all six manufacturing industries.     

出口的资源配置效应——基于中国制造业的经验检验

Melitz(2003)通过引入企业的生产率异质性,发现出口可以迫使行业内低效率的企业退出市场,继而通过行业内资源的重新配置实现行业总体生产率水平的提升。文章选取1999-2007年间中国制造业行业层面数据为样本,在分别运用索洛余值法、随机边界分析法(SFA)和数据包络分析法(DEA)对行业生产率水平进行测算的基础上,对贸易自由度与行业总体生产效率之间的关系进行经验检验,结果发现中国的出口对于行业加总的生产率水平的促进作用并不显著,没有明显证据表明异质性企业贸易理论提出的这一新的获得贸易利益的途径在中国的存在。最后,文章建议应该进一步消除各种阻碍自由贸易的壁垒,努力盈造行业内公平、有序的竞争氛围,继而获得由出口引致的通过行业内资源重新配置带来的贸易利得。     

Measuring comparative advantages in the Euro Area

A core principle in international economics is that the specialization of an economy on the basis of its comparative advantages leads to gains from trade. However, there is no empirical work directly linking comparative advantages and export specialization. This paper investigates whether the comparative advantages of countries have driven their export specialization. Panel unit root tests, panel cointegration tests, and panel causality tests are used to examine this relationship. We also use panel estimation methods that mitigate heterogeneity, cross-sectional dependence and endogeneity. The empirical analysis is based on annual Euro Area data for the period 1995–2016. Empirical results indicate that comparative advantages positively affect export specialization. Heterogeneous panel causality analysis results support that there is unidirectional panel causality running from comparative advantages to export specialization in most countries; and a reverse causal relation in Greece, Italy, and Portugal. Finally, we detect bidirectional causality in Ireland, Lithuania, Malta, and Slovakia.     

Ricardian productivity differences and the gains from trade

This paper evaluates the role of sectoral heterogeneity in determining the gains from trade. We first show analytically that in the presence of sectoral Ricardian comparative advantage, a one-sector sufficient statistic formula that uses total trade volumes as a share of total absorption systematically understates the true gains from trade. Greater relative sectoral productivity differences lead to larger disparities between the gains implied by the one-sector formula and the true gains. Using data on overall and sectoral trade shares in a sample of 79 countries and 19 sectors we show that the multi-sector formula implies on average 30% higher gains from trade than the one-sector formula, and as much as 100% higher gains for some countries. We then set up and estimate a quantitative Ricardian–Heckscher–Ohlin model in which no version of the formula applies exactly, and compare a range of sufficient statistic formulas to the true gains in this model. Confirming the earlier results, formulas that do not take into account the sectoral heterogeneity understate the true gains from trade in the model by as much as two-thirds. The one-sector formulas understate the gains by more in countries with greater dispersion in sectoral productivities.     

外部融资约束对企业出口行为的影响* ——基于中国企业普查数据的实证研究

本文采用世界银行2012年对中国境内2 700家企业的普查数据,分析企业外部融资约束对企业的出口倾向、出口强度的影响,本文的实证分析发现：企业面临外部融资约束时,不仅会显著降低企业参与出口的可能性,还会显著降低企业产品出口销售比例。不同的企业外部融资约束对企业出口行为有不同的影响。具体而言,贷款申请程序复杂、利率太高带来的外部融资约束会显著降低企业产品出口销售比例;贷款规模和期限不足带来的外部融资约束会显著降低企业参与出口的可能性;抵押要求太高带来的外部融资约束既会显著降低企业参与出口的可能性,也会显著降低企业产品出口销售比例。     

Quota removal and firm-level offshoring: Theory and evidence

Recent literature indicates that offshoring can effectively increase firm productivity and improve product quality. Therefore, global value chains have increased in importance. In this paper, we investigate the impact of export growth on firm-level offshoring. Removal of the quota on textile and clothing products in importing countries boosts China's exports of quota-restricted products. This removal offers a quasi-natural experiment. Using a difference-in-differences approach, we find that export growth induced by the quota removal increases the extensive and intensive margins of firm-level offshoring. The impact is more pronounced on domestic firms and firms that are engaged in ordinary trade. Our findings suggest additional gains from trade liberalization: trade liberalization not only boosts exports, but also enhances firm productivity and product quality through encouraging firm-level offshoring.     

Structural Estimation of Variety Gains from Trade Integration in Asia

This article studies the variety gains of trade integration in Asia. Adopting a heterogeneous firm model of trade of monopolistic competition allowed us to estimate not only the welfare gains because of country specialisation, but also the variety gains arising from trade integration. The underlying structural parameters were estimated econometrically, based on a large panel of firm‐level data for the Asian economies (ORIANA). Our empirical findings suggest that, when relaxing the assumption of firm homogeneity and accounting for export market entry costs, the gains from trade integration are higher than in conventional models with representative firms.     

Measurement and Modeling of the Economic Effects of Trade and Investment Barriers in Services

In this paper, the authors adapt the latest version of the Michigan Model of World Production and Trade to incorporate cross-border services trade and foreign direct investment (FDI). Firms are taken to be monopolistically competitive. Each firm produces products differentiated by the original R&D that defines the basic product and by location of production. Each firm faces a fixed cost in the country where production occurs, and sets an optimal mark-up for sales from each location. Firms locate production for export or for local consumption depending on the type of barriers faced. Barriers to trade in services take the form of an additional cost of employing variable capital and labor. The paper reports the impact on welfare, trade, factor prices, sectoral output, economies of scale, and activities of multinationals following the introduction of national treatment of multinational firms in all countries.     

International trade and technological progress in china: Evidence from time series

Using annual time series data (1983–2007), this paper examines the nexus between international trade and technological progress in China. The time series properties of the data are analyzed by bounds testing approach and vector error-correction model. The empirical results show that, it is not international trade volume and export trade volume but the import trade volume that is cointegrated with total factor productivity. The paper also finds that, in the long run, there is a reciprocal Granger causal relationship between the change of import trade volume and the change of total factor productivity, and in the short run, there is no evidence to support the Granger causality between these changes of the two variables.     

Endogenous trade policy in general equilibrium: An interaction of redistribution rule,trade openness,and labor market condition

Using a general equilibrium framework, the paper derives trade policy endogenously for a small country. It shows that, contrary to the existing literature, a lobbying industry is not guaranteed trade protection; it may even face trade taxes. Besides lobbying, trade policy depends on other factors such as the trade revenue distribution rule, income distribution across groups, trade openness, factor substitutability in production, industry employment size, and labor market flexibility. The paper also shows that the observed phenomenon of government preference for import tariffs over export subsidies—a long overdue puzzle—is an inherent outcome of lobbying equilibrium. It also shows that trade policies such as import tariffs and export taxes that have the same impact on economic market—Lerner symmetry (1936)—are driven by the same forces in the political market.     

Does exchange-rate uncertainty matter in the Malaysia–E.U. bilateral trade? An industry level investigation

Due to ambiguity in the past literature, researchers have examined exchange rate volatility effect on trade using disaggregated data in recent years. Previous research has focused more on aggregated data having aggregation bias which has led to unnecessarily over-generalized findings. This study investigates the impact of exchange rate volatility on the Malaysian bilateral trade flows with European Union using industry level data. Our empirical findings, based on auto-regressive distributed lag framework, suggest that many import and export industries experience exchange rate volatility influence in the short run, while a very small number of industries show this effect in the long run. Moreover, the adverse impact of financial crisis (2007–2008) is more prevalent on import industries compared to export industries.

The Effect of Capital Gains Taxation on Home Sales: Evidence from the Taxpayer Relief Act of 1997

The Taxpayer Relief Act of 1997 (TRA97) significantly changed the tax treatment of housing capital gains in the United States. Before 1997, homeowners were subject to capital gains taxation when they sold their houses unless they purchased replacement homes of equal or greater value. Since 1997, homeowners can exclude capital gains of $500,000 (or $250,000 for single filers) when they sell their houses. Such dramatic changes provide a good opportunity to study the lock-in effect of capital gains taxation on home sales. Using 1982-2008 transaction data on single-family houses in 16 affluent towns within the Boston metropolitan area, I find that TRA97 reversed the lock-in effect of capital gains taxes on houses with low and moderate capital gains. Specifically, the semiannual sales rate of houses with positive gains up to $500,000 increased by 0.40-0.62 percentage points after TRA97, representing a 19-24 percent increase from the pre-TRA97 baseline sales rate. In contrast, I do not find TRA97 to have a significant effect on houses with gains above $500,000. Moreover, the short-term effect of TRA97 is much larger than the long-term effect, suggesting that many previously locked-in homeowners took advantage of the exclusions immediately after TRA97. In addition, I exploit the 2001 and 2003 legislative changes in the capital gains tax rate to estimate the tax elasticity of home sales during the post-TRA97 period. The estimation results suggest that a $10,000 increase in capital gains taxes reduces the semiannual home sales rate by about 0.1-0.2 percentage points, or 6-13 percent from the post-TRA97 average sales rate.     

The pattern of specialization and economic growth: The resource curse hypothesis revisited

This paper explores the relation between countries’ pattern of trade specialization and long-term economic growth. It shows that countries specializing in the export of natural resource based products only fail to grow if they do not succeed in diversifying their economies and export structure. This conclusion follows from an empirical investigation that has three innovative features. First, it uses a dynamic panel data analysis. Secondly, it employs disaggregated trade data sets to elaborate different measures of trade specialization that distinguish between unprocessed and manufactured natural resource products and are informative about the countries’ trade diversification experience, their link to world demand trends and involvement in intra-industry trade. The final innovative aspect of the paper relates to our empirical findings: it is only specialization in unprocessed natural resource products that slows down economic growth, as it impedes the emergence of more dynamic patterns of trade specialization.
