Export externalities and economic growth

Feder formulated the first model with an explicit mechanism connecting international trade and economic growth. We present new econometric estimates of this unique model for 30 developing countries studied by Feder. We replicate Feder's 1964?–?73 cross-section estimates for 1974?–?83 and 1984?–?93 and find that the export variables lose significance and that the model has less explanatory power overall. We also try to improve on time-series estimates by Ram and find that the coefficient of Feder's total factor productivity differential in favour of the export sector was positive and significant for 18 of the 30 countries. The export externality coefficient proved to be positive and significant in 13 countries although significant multicollinearity occurs in the regressions for eight of the 13. Comparisons of the results among countries suggest that the impact of exports on growth depends on population size, trade orientation, and the importance of manufacturing.     

基于VAR模型的中国出口导向经济增长假说检验

由于数据结构、计量方法和变量选择的不同,有关ELG(出口导向型增长)假说的研究得出了不同的结论。系统分析FDI、出口贸易和经济增长的关系,将FDI纳入VAR模型中检验ELG假说,结果发现:中国是出口导向型经济增长,每增长1%的出口贸易开放度引发长期经济增长0.83%,出口贸易开放度是影响中国经济增长波动的主要因素,它对经济增长具有递增的促进作用;FDI具有持续提高中国出口贸易度的效应,从而促进中国的长期经济增长,FDI是引发中国出口贸易度提高和经济增长的Granger原因。     

Export-led growth: a survey of the empirical literature and some non-causality results. Part 1

The economic development and growth literature contains extensive discussions on relationships between exports and economic growth. One debate centres on whether countries should promote the export sector to obtain economic growth. An abundant empirical literature on this export-led growth (ELG) hypothesis has followed. We aim to contribute to this literature in two ways. In this paper, part 1, we provide a comprehensive survey of more than 150 export-growth applied papers. We describe the changes that have occurred, over the last two decades, in the methodologies used empirically to examine for relationships between exports and economic growth, and we provide information on the current findings.The last decade has seen an abundance of time series studies that focus on examining for causality via exclusions restrictions tests, impulse response function analysis and forecast error variance decompositions. Our second contribution is to examine some of these time series methods. We show, in part 2, that ELG results based on standard causality techniques are not typically robust to specification or method. We do this by reconsidering two export-led growth applications – Oxley’s (1993) study for Portugal, and Henriques and Sadorsky’s (1996) analysis for Canada. Our results suggest that extreme care should be exercised when interpreting much of the applied research on the ELG hypothesis.     

生产率的结构性变动对我国外贸顺差的影响

基于一般均衡模型,本文分析了生产率的结构性变动对我国外贸顺差的影响。从国内来看,我国制造业(出口行业)的生产率增速要高于服务业(进口竞争行业),在"放大效应"的作用下,出口行业产出增速较快,出口规模急剧扩张;从国际来看,我国在制造业方面的生产率增速要高于美国等发达国家,而在服务业方面彼此相差不大,由此引发了人民币实际汇率上升,要素贸易条件改善。上述因素的相互叠加,致使我国出口额超常增长,成为外贸顺差的主要来源。     

供给因素、结构变化、汇率与我国的双边贸易

基于考虑供给因素、结构变化的出口决定模型,采用两方程方法和单方程方法研究了外国GDP、中国GDP、结构变化、汇率与我国17个双边贸易之间的关系。研究表明:供给因素、结构变化对我国双边贸易有重要影响,供给因素对我国与美、澳、马、巴、新、泰、加进口及出口的影响存在严重的不对称性,结构变化对我国与德、印、加进口及出口的影响存在严重的不对称性,汇率对中国对15个贸易伙伴国出口与进口的影响存在严重的不对称性。采用出口除进口表示贸易收支做法的单方程方法的研究存在严重错误。经济增长模式对双边贸易有重要影响,人民币升值对我国双边贸易不平衡有一定的矫正作用,对改善我国双边贸易不平衡的国别分布有较大的积极作用。     

出口影响经济增长的机制:外部效应视角的实证考察

本文采用费德的外部效应模型,运用2002-2004年31个省市的相关数据进行实证分析,结果表明,出口部门通过要素边际生产力差异引起的资源重新配置效应和对非出口部门的正外部效应两条渠道促进经济增长。在考虑出口商品结构基础上,应用扩展的费德模型对农产品出口和非农产品出口的外部效应进一步考察发现,农产品出口总体上没有产生外部效应,而非农产品出口则产生了外部效应,存在间接促进经济增长的机制。由上述结论可解读出若干政策含义。     

Deforestation,foreign demand and export dynamics in Indonesia

This paper presents a dynamic, heterogeneous firm model of investment in environmental abatement and exporting. The model highlights the interaction between firms' environmental investment and export decisions on the evolution of productivity and export demand in timber manufacturing industries. The model is structurally estimated using Indonesian timber manufacturing data that captures firm-level variation in environmental investment and export behavior. The results suggest that environmental abatement has little impact on productivity dynamics, but does encourage growth in export demand. Counterfactual experiments quantify the impact of policy change on trade and abatement decisions.     

The Fallacy of Composition: A Review of the Literature

This paper reviews the literature on the fallacy of composition with an emphasis on labour‐intensive manufactures. It briefly addresses the protectionist and the partial‐equilibrium versions of the argument before focusing on general‐equilibrium considerations and the debate on the manufactures terms of trade of developing countries. The review indicates a potential fallacy of composition problem in labour‐intensive manufactures, where competition among different groups of developing countries for export market shares may constitute a new form of the fallacy of composition. The likelihood of a country that exports labour‐intensive manufactures to become subject to the fallacy of composition rises with the increasing integration of several strongly populated low‐income countries into world markets, while it declines with continuous structural change and favourable aggregate demand conditions particularly in developed and the advanced developing countries.     

集聚密度与城市全要素生产率差异——来自中国地级城市面板数据的证据

考虑集聚外部性对城市经济增长的影响,本文对我国285个地级市及以上城市1990～2008年间的城市全要素生产率进行测算和分解。生产过程中的技术进步、技术效率提高是我国城市生产率提高的主要因素,而与集聚外部性紧密相关的要素配置效率和规模效率仍是制约生产率增长的主要原因。城市经济密度对城市经济增长存在两种不同的影响途径:制造业在市辖区内的空间集聚体现为"拥挤"效应;人口空间密度则对地方产出的影响存在倒U型特征。人口因素仍然是我国城市经济增长的重要驱动因素,人口与制造业的空间"共聚"现象对城市产出有着显著为正的影响。     

Exporting and Environmental Performance: A Firm‐level Productivity Analysis

The objective of this paper is to study empirically the relationship between export orientation and firms’ environmental performance from different perspectives of trade theory. On the one hand, productivity heterogeneity is analysed within the new trade‐theoretical framework. The approach followed is to determine firm‐level productivity components, including an environmental productivity indicator (as a performance measure) and taking as reference the Spanish food industry. On the other hand, from the traditional comparative advantage perspective, this study also develops an export performance model to evaluate the effect of technology, environmental variables and factor endowment on exporting. The results show greater environmental productivity and corporate efficiency for export‐oriented firms. Our findings also determine the positive effect on firms’ export intensity of environmental performance as a factor of specialisation and technology proficiency.     

中国对外贸易和金融深化对全要素生产率的动态影响——基于状态空间模型的时变参数分析

本文基于新增长理论构建了贸易和金融内生化的生产率增长模型,并以1952-2006年的样本数据为基础,运用变参数分析方法就对外贸易和金融深化对我国全要素生产率的动态影响进行了分析。结果显示:进口贸易有利于全要素生产率增长,而出口贸易却与全要素生产率负相关;以经济货币化指标度量的金融深化有利于全要素生产率增长,而以经济金融化指标度量的金融深化同样有利于全要素生产率增长的预期却得不到经验证明。文章对上述结论进行了解释并提出了简要的政策建议。     

Do falling iceberg costs explain recent U.S. export growth?

We study empirically and theoretically the growth of U.S. manufacturing exports from 1987 to 2007. We use plant-level data on exporters' export intensity to identify the changes in iceberg costs over this period. Given this change in iceberg costs, we find that a GE model with heterogeneous establishments and dynamic exporting decision from a sunk cost of starting to export is consistent with both aggregate U.S. export growth and the changes in the number and size of U.S. exporters. The model also captures the gradual response of U.S. exports to the cut in iceberg costs. A model with a static exporting decision generates substantially less trade growth and misses out on the timing of export growth. We also study the interplay between changes in the structure of manufacturing and trade. We find that the growth in trade contributed little to the contraction in U.S. manufacturing while changes in the structure of manufacturing from changes in sectoral productivity, capital intensity, idiosyncratic shocks, and corporate taxation reduced U.S. export growth by as much as 10%.     

Migration of skilled workers and innovation: A European Perspective

Shifting comparative advantage,the nics,and the developing countries

It has been suggested that there have been shifts in comparative advantage for labor-intensive manufactures from the Newly Industrializing Countires (NICs) to other developing countries, permitting these latter states to export these products to the world market. An analysis of changes in exports for selected three-digit product categories for manufactures for sixteen countries from 1968 to 1976 and from 1976 to 1982, however, indicated that such shifts have not occurred. Many of the other developing countries that have expanded such exports have done so in the same product categories as the NICs, not different ones. In other cases, export gains of some developing countries were matched by losses by other developing states.     

Trade policy under firm-level heterogeneity in a small economy

We explore the effect of trade policy on productivity and welfare in the now standard model of firm-level heterogeneity and product differentiation with monopolistic competition. To obtain sharp results, we restrict attention to an economy that takes as given the price of imports and the demand schedules for its exports (a “small economy”). We first establish that welfare can be decomposed into four terms: productivity, terms of trade, variety and curvature, where the last is a term that captures heterogeneity across varieties. We then show how a consumption subsidy, an export tax, or an import tariff allows our small economy to deal with two distortions that we identify and thereby reach its first-best allocation. We also show that an export subsidy generates an increase in productivity, but given the negative joint effect on the other three terms (terms of trade, variety, and curvature), welfare falls. In contrast, an import tariff improves welfare in spite of the fact that productivity falls.     

Export Premium,Self‐selection and Learning‐by‐Exporting: Evidence from Chinese Matched Firms

This study empirically focuses on examining the hypotheses of export premium (exporters are more productive than non‐exporters), selection‐into‐exporting (more productive firms are ones that tend to become exporters) and learning‐by‐exporting (new export market entrants have higher productivity growth than non‐exporters in the post‐entry period). The propensity score matching method is used to adjust for observable differences of firm characteristics between exporters and non‐exporters, allowing an adequate ‘like‐for‐like’ comparison. We also use the difference‐in‐difference matching estimator to capture the magnitude of different productivity growth between matched new export market entrants and non‐exporters in the post‐entry period up to two years. Drawing on 2,340 Chinese firms in the period 2000–02, we find evidence for export premium and self‐selection, and once the firm has entered the export market there is additional productivity growth from the learning effect, in particular in the second year after entry.     

基于CMS模型的中国纺织品服装出口分析

本文利用恒定市场份额模型对1992年以来中国纺织品服装出口情况进行了分析,并与土耳其、印度和巴基斯坦做了横向对比。研究结果表明,中国纺织品服装出口的增长是进口市场的结构效应、自身的竞争效应以及结构与竞争力的交互影响的二阶效应共同作用的结果。其中竞争效应是带动当前中国纺织品服装出口增长的主要因素。土耳其、印度和巴基斯坦纺织品服装出口的增长主要是由于市场需求规模的扩大,其次是竞争力效应,二阶效应的作用非常小。     

出口贸易与全要素生产率增长的动态效应分析——基于中国省际面板数据的角度

大量的研究表明,出口贸易通过出口学习效应、出口溢出效应、出口规模效应和出口竞争效应促进了生产率的发展。我国省际面板数据的动态实证研究表明,出口量的增长不能促进我国全要素生产率的发展;人力资本和研发活动作为衡量一国吸收能力的指标,是发挥出口—生产率效应的关键因素;我国鼓励出口政策和引进外资政策的实施,使得出口—生产率效应具有明显的区域色彩。     

Global sourcing,productivity and export intensity

This paper investigates the effect of global sourcing on firm performances by using data on Danish manufacturing firms during the period 1995–2006. The results show that firms with better ex-ante characteristics are more inclined to source intermediate inputs from abroad. The results also show that firms that source from different locations possess different ex-ante characteristics; the most productive source inputs from high-wage countries while capital stock and being an exporter are more important factors when sourcing from low-wage countries. Moreover, controlling for the endogeneity of both the sourcing decision and location by using instrument variable and DiD matching approach, the results seem also to suggest that firms that source inputs from high-wage countries benefited from doing so in terms of higher growth of productivity and export intensity. Firms that source inputs from low-wage countries, on the other hand, seem not to have experienced any significant impact on neither productivity nor export, not even three years after they started to source inputs from these countries.     

Export variety and country productivity: Estimating the monopolistic competition model with endogenous productivity

This paper provides evidence on the monopolistic competition model with heterogeneous firms and endogenous productivity. We show that this model has a well-defined GDP function where relative export variety enters positively, and estimate this function over 48 countries from 1980 to 2000. Average export variety to the United States increases by 3.3% per year, so it nearly doubles over these two decades. The total increase in export variety is associated with a 3.3% average productivity improvement for exporters over the two decades. Overall, the model can explain 31% of the within-country variation in productivity (or 52% for the OECD countries), but only a very small fraction of the between-country variation in productivity.
