对外开放与发展中国家的收入不平等:基于亚洲和拉美国家的比较研究

本文基于要素禀赋理论,在将劳动力划分为低、中、高技能三类的基础上,选取亚洲和拉丁美洲部分发展中国家1960-2005年的数据,建立非平衡面板模型,分析两地区的开放对国内收入分配的影响。实证结果表明,亚洲和拉丁美洲发展中国家的对外开放确实对国内收入不平等起到推动作用。目前的开放有利于中等技能劳动力相对丰裕的发展中国家,而不利于低技能劳动力相对丰裕的国家。总体的贸易依存度对拉美不平等的推动作用更大,但外资对亚洲不平等的推动作用更大;制造业出口倾向于扩大拉美国家的收入差距而缩小亚洲国家的收入差距。     

Does Latin America Comprise Transnational ‘Subregions’?

We live in a world of nations, but also one of multi‐nation systems. These systems, or transnational regions, affect global economics, politics and diplomacy. Latin America is a widely recognised and documented transnational region. It contains subregional nation systems that might have all of the characteristics and significance of regions and might also affect the broader integration of Latin America. The author defines regionality on the basis of economic integration and measures it with two methods for Latin America, North America, three Latin American subregional systems and one arbitrarily defined nation system within Latin America. He finds a high degree of integration in Latin America, the Andean nations and the Southern Cone of South America. He finds only a modest degree of integration in North America and not significantly greater integration in South America than in Latin America. The division of Latin America into subregions is consistent with the incidence of sub‐regional trade initiatives in the past two decades and might be at least partly responsible for the limited progress to date towards Latin America‐wide integration. Latin American subregions might now be providing a foundation on which to build regionalism in the future.     

中国分地区进出口贸易与经济增长关系研究

从1981～2004年的统计数据看,我国同亚洲、非洲、欧洲、拉丁美洲、北美洲和大洋洲地区的进出口贸易与我国经济增长之间具有内在关系。我国同各地区的进出口贸易对经济增长的贡献存在明显差异。就长期而言,我国对欧洲地区的出口贸易对经济增长的贡献率最大,进口方面则是从北美洲的进口对我国经济增长的贡献率最大。这一结论为我国贸易政策的分地区调整提供了实证依据。     

Impacts of Emerging Asia on African and Latin American Trade: Projections to 2030

Rapid growth in Asia's emerging economies has boosted export earnings of resource‐rich economies over the past decade. Whether or not those high growth rates continue, how will structural changes in Asia alter the relative importance of their imports of primary products? This paper projects production and trade patterns of Africa and Latin America to 2030 under various growth and policy scenarios in Asia, using the GTAP model of the global economy. We compare a projection assuming relatively conservative economic growth in China and India with a projection in which those economies continue to grow rapidly (albeit slower than in the previous decade). We then compare our conservative growth baseline with two alternative scenarios: one assuming Africa and Latin America choose to invest more in public agricultural R&D to take advantage of Asian import growth; the other assuming China and India dampen that import growth by restricting their imports of key food grains (following the historical pattern of economies such as Japan and Korea). The final section summarises the results and draws out policy implications for Latin America and Africa.     

The effects of trade agreements on the growth of major Latin American economies

While the connection between trade openness and economic growth is generally assumed to be positive, empirically, it is not clearly demonstrable. Examinations of the relationship between trade and growth have taken a number of approaches, differing both in the empirical methods, as well as the proxies employed for trade openness, trade liberalization, and growth, but results have been decidedly mixed. Our research differs from prior studies in that it does not examine whether trade policy, trade liberalization or the level of trade itself enhances GDP; but rather whether participating in a specific type of trade agreement/union and/or the number of trade agreements to which a given country or region belongs enhances a country's level of growth. For this purpose, we study the relationship between trade agreements and growth for 18 Latin American countries between 1960 and 2008. Empirical analysis uses an adaptation of the neoclassical Solow growth model. Even though supporters of globalization advance the notion that involvement in trade agreements will help a country's economy, our findings suggest that that may not be consistently so.     

Third‐country Effects of Regional Trade Agreements

Does regionalism negatively impact non‐members? To answer this question, we examine the effect of regional trade agreements (RTAs) on imports from non‐members and the tariffs that they face. Using data from six RTAs in Latin America and Europe, we do not find evidence that implementation of the regional agreements is associated with trade diversion from third countries to regional members. Using detailed industry data on preference margins and most‐favoured nation (MFN) tariffs for three trade agreements in Latin America over 12 years, we find that greater preference margins do not significantly reduce imports from third countries. We also look at the effect of preferences on external tariffs. We find evidence that preferential tariff reduction tends to precede the reduction of external MFN tariffs in a given sector, offering evidence of tariff complementarity. Overall, the results suggest that regionalism does not significantly harm non‐members.     

Unexpected Effects of the Washington Consensus: Trade Liberalization and Migration Flows in Latin America

The traditional theory of international trade assumes that there is a substitution relationship between international trade and migration flows. However, trade liberalization in Latin America has come with an increase in emigration. This article, based on an econometric analysis for the period 1981–2002, shows that there is a complementary relationship between trade and international migration. One explanation is related to the Washington Consensus. In particular, higher labor market flexibility, in the context of trade openness, has resulted in higher levels of unemployment. Therefore, emigration represents a safety valve that reduces the pressure on Latin American labor markets.     

Using complex networks analysis to assess the evolution of international economic integration: The cases of East Asia and Latin America

This paper exploits recently-developed indicators based on network analysis to investigate the pattern of international integration followed by East Asian countries and compares it with the Latin American performance. Standard trade openness indicators fall short of portraying the peculiarity of the Asian experience, and of explaining why other emerging markets with similar characteristics have been less successful over the last 25 years. The analysis offers an alternative perspective on the issue regarding international economic integration by taking into account the whole structure of international trade relationships and by determining both the position of countries in the world trade network, and its evolution over time. We find that East Asian countries are more integrated into the world economy, as they have moved from the periphery of the network towards its core. Our results support the idea that the degree of openness matters but it is not enough to characterize economic integration. The number and identity of trade partners, and the specific individual structure of trade for each country, need to be incorporated in order to fully characterize international economic integration. By doing so, it is possible to argue that the integration process of the East Asian countries mirrors their high economic performance, while the lower degree of integration of Latin America can be related to the lack of economic development of the region, even though their degree of openness has increased.     

Age Structure and Trade Openness: An Empirical Investigation

This study focuses on the relationship between age structure and trade openness. We hypothesise that a higher share of the working‐age population in the total population increases trade openness, because the dependent population tends to spend more than the working‐age population on non‐tradable goods such as education and medical services. We estimate the effects of age structure on trade openness using panel data for 85 countries from 1991 to 2010. The empirical results show that the share of the working‐age population has a positive effect on trade openness. An increase in the share of the working‐age population is considered to be one factor that contributed to an increase in trade openness in the sample period.

The Gravity of China's African Export Promise

Africa's largest trade partner, China, criticised for exchanging resources for manufactures, has promised to increase imports and optimise the structure of trade with Africa. Using a gravity model of China's imports for the years 1995–2009, we explore potential dynamics for this promise, uniquely accounting for market economy recognition and Taiwan recognition. The former is associated with increased imports, while the latter effect is ambiguous and statistically insignificant. Comparison of projected against actual imports across three growth‐path‐aligned economic geography typologies – resource‐rich; landlocked and resource‐poor; coastal and resource‐poor – sets out China's imports trends in an abstract framework of African export potential. We find not only ‘under’ importing across a majority of resource‐poor countries. We also find that current trade policy is the least applicable to these comparatively poor exporters’ trade with China. If the latter are to serve a broader catalytic role in Africa's regional industrial transformation as compared to the role of coastal and resource‐poor countries in regional economic transformation in Asia and Latin America, China–Africa trade and investment policies may need additional thinking.     

Informality,tariffs and wealth

This article analyzes the interaction between changes in tariff protection, informality, inequality and aggregate income. First, we describe some new empirical evidence on informality, the formal/informal wage gap and trade openness in Latin American countries. Then we present a simple model characterized by three (empirically based) assumptions: (1) agents consume both formal and informal goods; (2) the government uses tariff revenues to purchase formal goods; (3) informality is a voluntary phenomenon. The model predicts that tariff reduction increases informality and wage inequality and that the maximization of income requires a positive level of tariff protection. The model's results are shown to be consistent with the empirical evidence concerning Latin American countries.     

Regional Productive Complementarity and Competitiveness

A positive international environment favors growth of the several economies in a given region, but it does not assure that the differences in the economic potential of the several countries are reduced in this process. Alternatively, the presence of productive complementarities might foster competitiveness and contribute to increasing the degree of homogeneity, even in situations of adverse terms of trade. This article reviews the experience of six sub-regional groups in Asia and Latin America in the last two decades. Latin America has recently benefitted from significant improvement in terms of trade and yet the economies in that region remain as different in their relative economic potential as they were in the beginning of the 1990s. In Asia, however, the negative impact of terms of trade has not blocked a quite fast pace of GDP growth; furthermore, productive complementarity has led to an increasing convergence of the several economies, with a sharp increase in their share of the international market. There are clear lessons from the Asian experience.     

Biased Technical Change in Agriculture and Industrial Growth

This paper presents a two‐sector growth model in which industrial accumulation is sensitive to the factor‐saving bias of technical change in agriculture. Agriculture features low factor substitutability and hidden unemployment and, in the baseline scenario, industrial growth is constrained by aggregate demand. Land‐saving innovations are then shown to raise rural employment, enlarge the domestic market for manufactures, and bolster industrial accumulation, in contrast to labor‐saving innovations. The baseline model and its extensions illuminate recent empirical studies which established that higher land yields boost industrial growth in developing countries, as well as accounts of the role of agricultural innovations in the industrialization of Japan, East Asia, and Latin America.     

International financial integration and real exchange rate long-run dynamics in emerging countries: Some panel evidence

The aim of this article is to provide new empirical evidence on the impact of international financial integration on the long-run Real Exchange Rate (RER) in 39 developing countries belonging to three different geographical regions (Latin America, Asia and MENA). It covers the period 1979–2004, and carries out ‘second-generation’ tests for non-stationary panels. Several factors, including international financial integration, are shown to drive the long-run RER in emerging countries. It is found that the new financial environment characterised by international financial integration leads to a depreciation of the RER in the long run. Further, RER misalignments take the form of an under-valuation in most MENA countries and an over-valuation in most Latin American and Asian countries.     

Who Supports Free Trade in Latin America?

This paper examines individual trade policy preferences across 17 countries in Latin America. The focus is on whether skilled or unskilled workers are more likely to support liberalised trade and on whether country characteristics, such as factor endowments, alter the preferences of skilled and unskilled workers. Based on the standard Heckscher‐Ohlin model and the Stolper‐Samuelson theorem, wage inequality in developing countries will decrease under free trade and unskilled workers will benefit. We find that on average skilled workers are more likely than unskilled workers to support free trade in Latin American countries. Separate country regressions reveal that this pattern is only statistically significant in 8 out of 17 Latin American countries. However, there are no countries in our sample in which unskilled workers are statistically more likely to support free trade than skilled workers, not even in the lowest skill‐endowed country in the sample. We also find that people from Latin American countries with higher GDP, faster growth, more cropland and a longer period of time since reform were more likely on average to support free trade.     

对外开放与中国制造业工资差距——基于劳动力供需模型的实证检验

选取1998—2006年中国26个省市的面板数据,利用结合劳动力供需的对外开放影响工资差距的理论模型,就对外开放对制造业熟练和非熟练工人工资差距的影响进行实证研究。研究发现:从全国样本看,外商直接投资有利于缩小制造业熟练与非熟练工人工资差距,而贸易开放与制造业熟练和非熟练工人工资差距则是一种倒"U"型的关系。在分地区讨论时,发现外商直接投资对中西部地区制造业熟练与非熟练工人工资差距的缩小作用要大于东部地区,贸易开放对中西部地区制造业熟练与非熟练工人工资差距存在显著的正向影响,而对东部地区的影响不显著,这进一步验证了上述倒"U"型关系的实证结果。     

Capital flows to Asia and Latin America: Does institutional quality matter?

Using a sample of 28 emerging market economies from Asia and Latin America spanning 1990–2013, we show that the marginal effect of capital flows on growth is positive and contingent on the threshold level of institutional quality (IQ). The conditional effect of capital flows holds for both the income per capita growth and total factor productivity (TFP) growth. We also determine the different threshold levels of IQ at which the marginal effect of capital flows is positive. The overall level of IQ in the Asian countries is superior to the Latin American countries and requires a lower threshold level to exert any positive effect. While the same conditional effect of IQ holds in Latin America for TFP growth, this effect is reversed in Asia. For very high levels of IQ (91st percentile), the marginal effect of capital flows on TFP growth in Asia is almost negligible. The marginal effects also vary based on the composition of capital flows in each region.     

Impact of trade openness on GDP growth: Does TFP matter?

ABSTRACT

The objective of this study is to empirically explore the impact of trade openness on GDP growth initiating with the idea that trade openness cannot be fully characterized through the different openness measures only, we propose to account for total factor productivity (TFP) development level as an additional dimension of countries’ trade integration. Our empirical application is based on 35 years’ balanced panel of 82 countries spanning 1980–2014. To address the potential endogeneity issue, we use the system GMM estimator developed for dynamic panel data models. The results outline that there exists an interesting non-linear pattern between trade openness and GDP growth when TFP development level is taken as an intervening variable into account: trade may have a negative impact on GDP growth when countries have specialized in low-TFP development level; trade openness clearly boosts GDP growth once countries exhibit a minimum threshold of TFP development level. Therefore, there is some pattern of complementarity between trade openness and TFP development level so that the higher the TFP development level, the higher the impact of the trade openness on GDP growth.     

Trade openness and the environmental Kuznets curve: Evidence from Chinese cities

This paper examines the impact of economic growth and trade openness on environment in 261 Chinese cities over the period of 2004–2013, using recently developed continuously updated fully modified method which allows for both cross-sectional dependence and endogeneity. Two types of pollutants, industrial waste water and sulphur dioxide are investigated, and three measures of openness are employed in the regression. From the results, we find that the environmental Kuznets curve hypothesis holds not only for the whole China, but also in different regions. It is estimated that wastewater pollution increases with economic development until per capita GDP reaching the turning point of 42,991–48,828 yuan (in constant 2002 price), which varies depending on the specific measure of trade openness. The turning point for sulphur dioxide is found to occur at a much lower income level around 9,588–10,663 yuan per capita GDP. Furthermore, export is mostly found to be positively related with pollution and the impact of import is likely to be negative for both the whole China and across regions, if the significance is identified in the estimation results.
