How much have been the export products changed from homogeneous to differentiated? Evidence from China, Japan, and Korea

Many international trade theories and evidence suggest that trade in homogeneous and differentiated goods is different, and trade performance depends significantly on the extent of product differentiation. First this paper classifies the three countries' export products using Rauch's [Rauch, J. (1999). Networks versus markets in international trade. Journal of International Economics, 48, 7–35] classification scheme. This paper suggests a sophisticated technique to obtain the extent of product differentiation in a country's export, implied by Dixit and Stiglitz [Dixit, A., & Stiglitz, J. (1977). Monopolistic competition and optimum product variety. The American Economic Review, 67, 297–308] model in which the smaller is the elasticity of substitution between varieties the greater is the extent of product differentiation. This is an attempt to identify the extent of product differentiation in each country's export basket by estimates of the elasticity of substitution. The estimated elasticities of substitution vary across countries. The most interesting empirical finding is that the China's export structure has been rapidly shaped into differentiated products. However the extent of product differentiation in Japan and Korea's exports has relatively less varied.     

Business fluctuations in Italy, 1861-1913: The new evidence

Band-pass filters and structural time-series models are applied to the new estimates of Italy’s domestic product from 1861 to 1913. These indicate a strong four-year cycle, derived from the agricultural sector, which curiously (and perhaps spuriously) vanishes after 30 years. Over the longer term GDP and the services reflect the long swing in industrial production, tied to the investment cycle. Agriculture seems marked instead by a further cycle of some 12-15 years, and also by a long wave related to the sector’s terms of trade.     

Monetary Union,Trade Integration,and Business Cycles in 19th Century Europe

This paper studies the impact of monetary arrangements on trade integration and business cycle correlation in late 19th century Europe. We estimate a gravity model and show that tighter monetary integration was associated with substantially higher trade, as in recent studies using contemporary data. For instance, the Austro-Hungarian monetary union improved trade between member states by a factor of 3. To explain this, we build and estimate a simple model where greater monetary integration weakens the current account constraint by fostering business cycle co-movements.     

Value,Structure and Spatial Distribution of Interprovincial Trade in China

This study uses two different datasets to explore the stylized facts of interprovincial trade in China during the recent two decades. One dataset provides the magnitude of bilateral interprovincial goods trade calculated using firms' value‐added tax invoices. The other supplies estimates of interprovincial trade using provincial input–output tables. We find that China has both a large value and a high growth rate of interprovincial trade, but there still exists a home bias in internal trade for most provinces. In addition, disaggregation by product shows that the manufacturing sector has the largest share of interprovincial trade and this share continues to grow. Finally, the spatial distribution of trade suggests that all provinces can be clustered into a smaller number of trade areas with large intra‐cluster trade. Therefore, China's central government should make more effort to reduce local protection, stimulate domestic demand and coordinate interregional trade among local jurisdictions.     

Trade within an industry in the presence of vertical product differentiation and dynamic increasing returns

This paper investigates a case of trade with dynamic learning, a continuum of varieties of a vertically differentiated product, and two countries differing only slightly in population size. The results are as follows. Since increasing returns continuously allow consumers to afford higher-quality versions of the good, a quality-based product cycle is generally required for the two initial market shares to persist over time; however, with dynamic learning the conditions for such a cycle to take place are severe. Then, in spite of the self-reinforcing nature of the pattern of spezialization, one of the two countries' market segments (the lower-quality one) is likely to shrink endogenously over time.     

Preference shocks,international frictions,and international business cycles

Replicating the degree of cross-country comovements of macroeconomic aggregates, dynamics of prices and quantities of international trade, and the behavior of consumption and labor remains an important challenge in international business cycle literature. This paper incorporates preference shocks into a standard two-country model in which there exist international frictions, such as costs of transportation and restrictions to international asset trade. Country-specific preference shocks that generate fluctuations in each country's consumption and labor solve the puzzles, except for the discrepancy between theory and data regarding international trade variables. The presence or absence of international frictions plays a limited role in solving the puzzles.     

Skilled-Labor Intensity Differences Across Firms,Endogenous Product Quality,and Wage Inequality

This paper proposes a theory to explain the relative wage-rate increase for skilled labor that results from trade liberalization that relies on within-sector reallocations of production resources (skilled and unskilled labor) across firms. Motivated by some stylized facts, in a model with firm heterogeneity, including firms that differ in their skill intensity even within a narrowly defined industry, firms with relatively high skill intensity that are more likely to be exporters, and a positive association between a firm’s skill intensity and its product quality, I develop a general equilibrium model where firms with a higher skill intensity endogenously choose a higher-quality product, and tend to be more profitable. In this framework, a reduction in trade costs allows members of the workforce to reallocate to more efficient firms that produce higher-quality products, using their skilled labor more intensively, resulting in a rising skill premium. The main sources of the increasing wage inequality that followed trade openness are a positive link between a firm’s skill intensity, its product quality, and quality competition.     

Trade,the Staple Theory of Growth,and Fluctuations in Colonial Singapore, 1900–39

Our paper enquires into the nexus between trade, growth, and fluctuations in the British colony of Singapore during the early twentieth century. Hitherto, little quantitative economic history has been written on this great entrepôt of Southeast Asia due to a lack of data. We overcome this limitation by utilising the gross domestic product series recently constructed for the pre‐war period by Sugimoto. This comprehensive data set enables us to explore the relevance and applicability of the staple theory of export‐led growth to colonial Singapore through cliometric analyses. The results suggest that foreign trade had acted both as an engine of growth and a source of economic instability.

The impact of intra-industry trade on business cycle synchronization in East Asia

This paper empirically analyzes distinctions between intra- and inter-industry trade indices. The research indicates that the co-movements of business cycles are influenced more through the intra-industry trade channel than by the total volume of trade itself. As trade integration among Asian countries increased, business cycle synchronization among these countries was expected to expand through trade transmission. Inter-industry trade resulting in higher specialization will induce less synchronized business cycles, while intra-industry trade could lead to increased business cycle synchronization. Moreover, I find that increased business cycle synchronization, as one of the optimum currency area criteria, is overemphasized.     

Agricultural Exports,Tariffs and Growth

This article presents a Ricardian model of trade with learning-by-doing to study the effect of barriers to trade in products with low growth potential on the long-run economic growth. The model shows that, when elasticity of demand for the product with a lower learning potential is lower than unitary, a reduction in the tariff imposed on this product, may shift the demand toward the product with a higher learning potential, thus enhancing economic growth in the exporter economy. Therefore, the current trend of reduction in tariffs on agricultural exports not only generates a positive welfare effect in the short run, but may similarly be beneficial for developing economies in the long run, since it also increases their incentive to develop sectors with higher growth potential.     

R&D,trade in intermediate inputs,and the comparative advantage of advanced countries

This paper examines the accumulation of physical capital versus knowledge (R&D) capital as a determinant of advanced countries’ comparative advantage. I show that advanced countries are abundant in R&D resources, specialize in knowledge-intensive stages of high-technology industries, and outsource labor-intensive stages of the industries to labor-abundant countries. In contrast, global data on production and trade cannot support the conventional view that advanced countries specialize in and export capital-intensive goods. My results indicate that the accumulation of knowledge capital plays a vital role in explaining advanced countries’ comparative advantage.

The nature of Japan's comparative advantage, 1965-80

This paper compares the dynamic factor proportions theory to the product cycle theory in explaining Japan's comparative advantage for the 1965-80 period. Three tests were used: (1) domestic Japanese relative prices of more and less competitive export commodities; (2) trends in capital-labour ratios, skill ratios, R&D intensity and product turnover for Japan's manufactured exports; (3) price elasticities over time of Japan's exports. The results suggest that: (1) the product cycle must be considered along with the factor proportions theory for the pre-oil shock period; (2) the product cycle theory is superior for the post-oil shock period.     

生产分割、周期协同与主要贸易伙伴的关联:1995～2008年

利用中国与17个主要贸易伙伴国1995～2008年的投入产出表和分行业双边进出口贸易数据,测算不同时期的双边生产分割程度。然后基于动态面板数据模型,综合分析了影响国际经济周期协同的决定性因素。研究发现,贸易在影响中国与主要贸易伙伴国的国际经济周期协同中存在两种不同方向的作用机制:以双边生产分割程度度量的互补品贸易对经济周期协同存在正向影响,而以双边贸易强度指标度量的替代品贸易对经济周期协同存在负向影响。同时研究还表明,双边金融整合程度对国际经济周期协同有正向影响,而产业结构相似性对国际经济周期协同的影响并不显著。

Die another day: duration in German import trade

International trade patterns at the product level are surprisingly dynamic. The majority of trade relationships exist for just a few, often only one to three, years. In this paper, I examine empirically the duration in German import trade at the 8-digit product level from 1995 to 2005. I find that survival probabilities are affected by exporter characteristics, product type and market structure. Specifically, I show that the duration of exporting a product to Germany is longer for products obtained from countries that are economically large and geographically close to Germany; for products with large trade value and a low elasticity of substitution; and for trade pairs that command a large share of the German import market and are characterized by two-way trade.

China and India in World Trade: Are the Asia Giants a Threat to Malaysia?1

Abstract

With higher shares in world merchandise trade and improvements in product quality, China is better positioned than India in the near term for influencing global trade. From the Malaysian perspective, China represents a non-negligible share in Malaysia's trade. The trends in bilateral trade with both Giants however suggest that competition has intensified. Relative to India, China appears to promulgate a more influential role on Malaysia via higher commodity overlap in external markets, greater matched trade that is of vertical differentiation, distinct quality shifts and negative adjustment pressures. Within this broad rubric of trade-induced changes, there is no evidence of skill upgrading for Malaysia in trade expansion with both Giants. This mirrors the lack of product quality improvements and the low levels of export values of high quality varieties in matched trade. Hence trade induced changes from the Giants that have been cited to be favourable from the Malaysian perspective in previous studies, may have been grossly overstated.     

Foreign direct investment, intellectual property rights, and wage inequality in China

This article incorporates foreign direct investment (FDI) and product differentiation in a general equilibrium trade model. The analysis shows that freer trade and FDI will upgrade China's technology, improve its skills of labor, and increase the competitiveness of local firms in the international market. At the same time, the relative wage of skilled labor to unskilled labor will rise. The size of this rise will be affected by the degree of protection for intellectual property rights. These theoretical results are consistent with empirical evidence. The analysis provides insights in coordinating policies on FDI, labor market reform, and intellectual property rights protection.     

Trade,technology, and the labour market: impacts on wage inequality within countries

This paper focuses on the widening wage inequality between skilled and unskilled workers within countries and discusses whether trade and technology have contributed to this trend. The paper develops an analytical framework for wage inequality that traces the determinants and their relative roles in wage inequality in different stages of the development of trade theory, especially those considering new evidence after 2011. We find that technology plays a key role in the rise of wage inequality in most countries, while trade plays an increasingly crucial and more complex role in recent years. Skill supply institutions, such as education systems supplying skilled labour or unions participating in wage‐setting processes, suppress the rise of wage inequality in some countries. The paper further outlines the mechanisms through which trade affects wage inequality, including offshoring, firm heterogeneity, labour market frictions and global value chains. We find that trade has indirect effects on technology, which further enlarges the wage inequality among skills. The paper also discusses the policy implications of the impacts of trade and technology on wage inequality.
