Unequal factor prices and incomplete specialization in a Heckscher-Ohlin model of endogenous growth

Two-factors, two-goods Heckscher-Ohlin trade theory predicts that under certain circumstances factor prices equalize if countries are incompletely specialized. If at least one country is completely specialized no factor-price equalization obtains. Different factor rewards and free trade, however, are not automatically linked to complete specialization: in a Heckscher-Ohlin model of endogenous growth where the countries differ in their individual discount rates, a situation of incomplete specialization and different factor rewards will result.     

“过渡期”后我国外贸战略创新的探讨

"过渡期"后,在贸易和投资自由化显著增强的新形势下,由于我国外贸发展现存的缺陷等原因,我们需要创新外贸战略,建立出口促进和产业保护的新型长效机制,使我国参与国际分工和贸易的优势基础从劳动力的比较优势转到科技、品牌、企业素质和国际规则构建等综合经济优势上来,提高我国国际分工的位次,向贸易强国跨越。     

海外研发、贸易摩擦与创新绩效：来自中国高科技上市公司的经验证据

海外研发被视为后发国家实现技术赶超的有效路径,现有文献基于经贸自由化的前置条件证实了海外研发提升创新绩效的反哺作用。然而在全球贸易保护主义抬头的背景下,资源要素的自由流动愈发困难,海外研发能否发挥应有的作用尚不得而知。为此,基于中国高科技上市公司的数据,本文探索了中美贸易摩擦如何影响中国企业的海外研发绩效。研究发现,中美贸易摩擦非但没有侵蚀中国企业的海外研发绩效,反而产生倒逼效应,推动中国企业提升投资效率并积累国际投资经验,继而增强了海外研发的反哺作用。通过区分海外研发目的地,本文进一步发现倒逼效应在赴非美国家的样本中更显著。赴美研发受到贸易摩擦的冲击更为直接,稀释了提升投资效率和积累国际化经验所带来的收益。研究结论深化了国际商务理论关于贸易保护和壁垒如何影响跨国企业投资绩效的相关研究,为中国企业在高度不确定的投资环境下如何充分释放海外研发的潜能提供启示。     

中国自贸试验区建设吸引了外商直接投资流入吗? ——来自216个地级市的面板数据考察

自由贸易试验区作为中国深化改革与开放的一项政策实验,尝试通过制度创新实现贸易、投资自由化,其政策效果究竟如何？研究基于2000—2019年216个地级市面板数据,运用广义合成控制法实证检验了我国自贸试验区对外商直接投资的影响。研究发现,自贸试验区在一定程度上吸引了外商直接投资流入,且随着时间推进,其对外商直接投资的正向促进作用愈发明显;控制其他政策因素的多期双重差分法的结果进一步验证了上述结论的可靠性。研究进一步发现：自贸试验区吸引外商直接投资的政策效果存在差异性。从时间趋势看,不同批次自贸试验区的政策导向不同,对外商直接投资的影响力度不同;从区域层面看,自贸试验区建设中,东部地区对外商直接投资的促进作用更强,中部地区的政策效应存在滞后性,西部地区吸引外商直接投资力度有下降趋势;从城市规模看,自贸试验区建设对一线城市外商直接投资的吸引力度更明显,级别越低的城市可塑性越强,吸引外商直接投资流入效果越显著。从不同发展梯度看,沿海自贸试验区对外商直接投资的正向影响程度高于内陆自贸试验区,而沿边自贸试验区并未发挥出对外商直接投资的吸引作用。     

国际贸易和国际直接投资一体化的理论基础探析

传统的新古典国际贸易理论否定国际直接投资的存在空间,但经济全球化的迅速发展现实则表明国际贸易和国际直接投资是相互促进发展的。本文回顾了国际贸易和国际直接投资理论融合的历史和现状,着重分析了内在规模经济（内在比较优势）的理论渊源,探讨了贸易投资一体化的理论基础是基于内在规模经济的国际分工。     

Trade and Real Wages: a Macroeconomic Model*

We offer a new paradigm to understand the effects of trade on factor rewards. It utilizes the classical‐Keynesian model, and shows that normally a country’s trade deficit hurts labor by lowering the real wage, but benefits the owners of capital. The effects of tariffs on factor rewards and employment are opposite to those of the trade deficit, which falls with a rise in the tariff rate. Countries with trade shortfalls unambiguously benefit from their tariffs, because laborers far outnumber capitalists, who suffer from the declining interest rate. Thus, tariffs lead to a rise in social welfare in trade‐deficit countries.     

Existence of equilibrium in the Helpman–Krugman model of international trade with imperfect competition

Helpman and Krugman (Market structure and foreign trade. Increasing returns, imperfect competition, and the international economy. MIT Press, Cambridge, 1985) provide a synthesis of the traditional factor proportions theory of international trade and the theory of international trade due to the exploitation of scale economies in imperfectly competitive markets. They derive illuminating results about trade patterns and gains from trade, among other things, leaving unanswered the question of existence of equilibrium, however. The central significance of their characterization of properties of free trade equilibria with inter-industry and intra-industry trade calls for an analysis of existence of equilibrium. This is the object of the present paper. We prove the existence of equilibrium for the integrated multi-sector multi-factor Helpman–Krugman economy without national borders. Well-known conditions ensure that the world economy under free trade reproduces this equilibrium and thus establishes existence of a free trade equilibrium. Since an equilibrium of the integrated economy is not necessarily unique, the same holds true for a free trade equilibrium.     

International business cycles and the relative price of investment goods

Abstract Is the relative price of investment goods a good proxy for investment specific technology? We model this relative price in a flexible price international economy with two fundamental shocks, namely, the total factor productivity (TFP) shock and the investment‐specific technology (IST) shock. We show that the one‐to‐one correspondence between the IST shock and the relative price of investment goods breaks down in an international economy because of the short‐run correlation between the terms of trade and the relative price of investment goods. The data congruent negative correlation between the investment rate and the relative price of investment goods thus does not necessarily reflect decline in investment frictions (rise in IST), as suggested by many studies. A calibration experiment with the US data demonstrates that such an inverse relation between rate of investment and the relative price of investment goods basically reflects the positive effect of TFP on the terms of trade for a broad range of economies where the home bias in consumption exceeds investment and there is a sizable adjustment cost of investment.     

中国对外贸易失衡的影响因素*——基于贸易增加值（TiVA）测算数据的实证分析

中国持续对外贸易顺差引起了学者们的广泛关注。然而现有文献大都基于传统贸易统计方法，没有考虑全球价值链背景下中间品多次跨越国界的重复计算问题，无法反映中国真实的贸易顺差水平。本文基于WIOD数据库1995-2011年的数据，采用投入产出领域的贸易增加值（TiVA）方法，测算出中国与38个贸易伙伴之间的增加值贸易顺差，并对其影响因素进行了实证分析。研究发现，中国加入WTO之前人民币汇率升值对贸易顺差的影响较小而且不显著，而加入WTO之后，人民币汇率升值可以有效降低中国的贸易顺差。在华FDI总额对贸易顺差的影响呈现出相似的特点，即加入WTO之前，总体FDI不显著，加入之后影响显著。FDI来源地区分析显示，美国和亚洲四小龙在中国内地FDI增加可以显著提升中国内地的贸易顺差，而日本和德国在华FDI则会降低中国内地的贸易顺差。     

贸易保护主义的制度经济学分析

随着国际贸易经济的发展,资产在国际间的流动逐渐成为国际贸易中不可忽略的一个重要组成部分,其是否发生沉淀成本有可能对国际商品贸易和投资产生重要影响,不仅会影响国际贸易的总量和产品构成,而且还会影响一国贸易政策的选择。如果一国进行了沉淀成本投资,就会使其在贸易谈判中陷入进退两难困境,失去了讨价还价的力量,并影响其在贸易利益上的分配格局。因而为了摆脱这种被要挟和被控制的风险,政府实行一定的保护主义政策是十分必要的。

The Vertical Multinational Enterprise and International Trade

This paper analyzes an endogenous vertical multinational enterprise by explicitly modeling a distortion in the intermediate goods sector. Firms invest abroad to lower the cost of multistage production. The implications for international trade and investment differ markedly from the conventional wisdom of multinationals. Particularly, intrafirm trade in intermediates implies vertical investment complements rather than substitutes for trade. The decision to become a multinational depends on the level on foreign factor prices, the nature of the competition with foreign suppliers, transport, tariffs, and subsidiary plant costs. Marginal change in tariff may result in unintended welfare jumps as firm configuration shifts.     

Geopolitics and the Genealogy of Free Trade Zones in the Persian Gulf

Free trade zones have been championed by policy makers as important mechanisms for the “economic liberalisation” and “globalisation” of the Middle East. While a growing number of political economists have begun to investigate the performance of these projects, few have considered why states voluntarily limit their sovereign powers by establishing these liberalised territories. To address this question, this paper studies the Jebel Ali free trade zone in Dubai (UAE) and the Kish free trade zone in Iran, two of the earliest such projects in the region. Rather than being products of neoliberal ideology or pressure from advanced industrial economies, the essay argues that paradoxically these zones were developed by the Iranian state and Dubai emirate to project territorial sovereignty in turbulent geostrategic settings and moments as well as nodes to circulate rent to domestic and international members of ruling coalitions. The geostrategic and state-building logics informed when, where, and how these projects were developed. More generally, this analysis illustrates that the Middle East is neither absent from the process of globalisation, nor does it simply respond passively and reactively to this complex process. Free trade zones are an example of local strategies working in consort with international processes to fashion new forms of economic and political interconnectedness.     

对外直接投资的贸易效应研究--基于中国经验的实证分析

对外直接投资与出口贸易之间的关系一直是相关理论和实证研究的争论主题。运用引力模型,对中国FD I的贸易效应进行实证分析表明:中国对东道国的直接投资促进中国对东道国的出口,但对从东道国的进口却具有替代效应。因此,大力促进中国对外直接投资,是促进中国的对外出口、绕开东道国贸易壁垒的重要途径。

The high road and the low road to international competitiveness: Extending the neo‐Schumpeterian trade model beyond technology

Extending the neo‐Schumpeterian trade model, we estimate a ‘social‐gap’ model for a group of 17 OECD countries over the period 1975–1995. We find that government spending on social protection, employment protection regulations, union density, strike activity, and income security in the labor market (all measured in ‘gap’ form) are statistically significantly related to changes in international competitiveness. Specifically, we find some support for a Calmfors–Driffil, nonlinear, relation between cooperative labor relations and social spending patterns on the one hand, and international trade (and inward foreign investment) competitiveness on the other, implying that countries with relatively stronger institutional arrangements have better international economic performance than countries in the middle of the scale of conflict and cooperation. Our results indicate that models focusing solely on innovative effort are misspecified, and may suffer from an omitted variable bias caused by the absence of consideration of other institutional factors influencing international trade and investment.     

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.     

市场结构、规模经济与中国铁矿石定价策略

铁矿石定价问题对中国经济的平稳增长有明显影响。本文尝试性地建构了一个引入贸易中介的生产-贸易-消费的三分法结构分析框架,来探讨国际铁矿石定价问题及中国策略。基于国家和企业的双层面三环节结构分析发现,高寡占的生产者结构对应于高竞争性的贸易中介结构和消费者结构是国际铁矿定价格局的结构成因,也是中国制定相关铁矿石贸易和产业政策的重要现实约束。基于生存能力法的规模经济测度发现,铁矿石贸易的规模经济区间为5％以下;铁矿石消费环节的规模经济区间为10％以下,导致了多种形式的铁矿石贸易中介组织共存的特征。论文还从生产-贸易-消费的产业定价策略分析方法出发,提出了中国可资利用的铁矿石定价策略。     

International trade,technological change and wage inequality in the UK economy

This paper examines the joint impact of international trade and technological change on UK wages across different skill groups. International trade is measured as changes in product prices and technological change as total factor productivity (TFP) growth. We take account of a multi-sector and multi-factor of production economy and use mandated wage methodology in order to create an well-balanced approach in terms of theoretical and empirical cohesion. We use data from the EU KLEMS database and analyse the impact of both product price changes and TFP changes of 11 UK manufacturing sectors on factor rewards of high-, medium- and low-skilled workers. Results show that real wages of skill groups are significantly driven by the sector bias of price change and TFP growth of several sectors of production. Furthermore, we estimate the share of the three different skill groups on added value for each year from 1970 to 2005. The shares indicate structural change in the UK economy. Results show a structural change owing to decreasing shares of low-skilled workers and increasing shares of medium-skilled and high-skilled workers over the years.     

How trade and capital restrictions affect the probability of a balance of trade disturbance

Free market economists argue that national authorities avoid restrictions on the free movement of goods, services and financial capital between countries. Yet, countries continually choose to restrict the flow of capital both into and out of the country. Why is this done? Is it done to protect the domestic banking system, to control the domestic money supply, to manage the exchange rate, to provide stability for internal markets or to avoid wide swings in the availability of capital? Are these controls effective in precluding wide swings in a country's international trade balance? This article uses panel data in a logit model to analyse policy choice with respect to an international trade and/or investment regime. The goal is to identify choices effective in reducing the likelihood of a severe Balance of Trade Disturbance (BTD) and determine if the appropriate choice is related to per capita income (pci).
