Does the measurement of intra-industry trade matter?

Does the Measurement of Intra-Industry Trade Matter? — This paper discusses different methods of capturing the main aspects of the Chamberlin-Heckscher-Ohlin-Samuelson model. Of particular interest are the distinction between horizontal and vertical intra-industry trade, the adjustment of aggregation biases, and the definition of inter- and intra-industry specialization at product level. The main findings are that it is important to disentangle horizontal and vertical intra-industry trade, and to consider specialization patterns within refined product groups. Moreover, there is a nonlinear relationship between intra-industry trade and economies of scale that may explain contradictory results in the literature.     

Tests of the empirical classification of horizontal and vertical intra-industry trade

Tests of the Empirical Classification of Horizontal and Vertical IntraIndustry Trade. — Using longitudinal data this paper shows the separation of international trade in (a) inter-industry trade, (b) horizontal intra-industry trade, and (c) vertical intra-industry trade used in the empirical trade literature to be non-stable at the individual product level. The high level of vertical intra-industry trade mentioned in the empirical literature probably covers up many products shifting between e.g. vertical and horizontal intra-industry trade. The paper therefore questions the work of the last decade in the measurement of intra-industry trade.     

Country-specific factors and the pattern of horizontal and vertical intra-industry trade in the UK

Country-Specific Factors and the Pattern of Horizontal and Vertical Intra-Industry Trade in the UK. - A large number of empirical studies have investigated the relationship between country-specific factors and total intra-industry trade (IIT). One important shortcoming of this literature is that it ignores the distinction between horizontal and vertical IIT and ignores the fact that they may have different determinants. This paper disaggregates UK IIT into its horizontal and vertical components and, using bilateral trade data, estimates a series of models incorporating countryspecific variables. The results suggest that vertical IIT is more important in the UK than horizontal IIT and that the inter-country pattern of vertical IIT is systematically related to a range of explanatory variables.     

The nature and causes of intra-industry trade: Back to the comparative advantage explanation? The case of Spain

The Nature and Causes of Intra-Industry Trade: Back to the Comparative Advantage Explanations? The Case of Spain. — The aim of this paper is to contribute empirically to the knowledge of the nature and causes of intra-industry trade (IIT), distinguishing between vertical and horizontal IIT. To this end, we estimate a more general empirical model than those used in previous studies, by introducing simultaneously both national and industry-specific variables which include measures for human and technological capital endowments. The results show that vertical IIT is positively related to industry technological intensity and differences in human and technological capital endowments between countries. On the other hand, horizontal IIT is explained by the traditional monopolistic competition model.     

Labour-market effects of intra-industry trade: Evidence for the United Kingdom

Labor-Market Effects of Intra-Industry Trade: Evidence for the United Kingdom. — According to the “smooth adjustment hypothesis”, the labor-market adjustment costs entailed by trade liberalization are lower if trade expansion is intra-industry rather than inter-industry in nature. In this paper, we study the link between trade and labor market changes in UK manufacturing industries during the 1980s. We use industry-level measures of unemployment duration and wage variability as proxies for adjustment costs, and we relate them to various measures of intra-industry trade. Our evidence offers some support for the smooth adjustment hypothesis.     

Intra-industry trade as an indicator of labor market adjustment

Intra-Industry Trade as an Indicator of Labor Market Adjustment. — A growing body of recent empirical research uses measures of change in intra-industry trade as indicators of labor market adjustment. In this paper, we argue that the theoretical foundations for this work are problematic. To make this argument we develop a simple model with both inter- and intra-industry trade and adjustment. We find that changes in domestic absorption, which influence trade flows but which are distinct from production changes, make changes in IIT an unreliable guide to labor market pressure.     

Two-way trade between unequal partners: The EU and the developing countries

Two-Way Trade between Unequal Partners: The EU and the Developing Countries. — This paper analyses the intra-industry trade specialization between the EU and the developing countries between 1980 and 1992. It shows that EU intra-industry trade with the developing countries has greatly increased and that the traditional measure of intra-industry trade, the Grubel-Lloyd index, is inappropriate when applied to trade between developed and developing countries. By and large, the empirical analysis confirms that intra-industry trade between the developed and the developing countries increases with average and per capita income, and with reduced differences in economic size and capital-labour ratios.     

Vertical specialization and intra-industry trade: The role of factor endowments

Vertical Specialization and Intra-Industry Trade: The Role of Factor Endowments. — In this paper, we use vertical differentiation models of the Falvey-Kierzkowski type to study the effects of differences in factor endowments on vertical intraindustry specialization. We focus on Spanish intra-industry trade, as Spain typically exports low-quality varieties to the northern countries of the OECD and high-quality varieties to the southern ones. In order to achieve more general results, we consider different types of productive factors: physical, human and technological capital. Our results confirm that factor endowments play a significant role in explaining vertical intra-industry specialization.     

Adjustment,employment characteristics and intra-industry trade

Adjustment, Employment Characteristics and Intra-Industry Trade. — In this paper we use data on individual workers to investigate a number of dimensions of adjustment and relate these to trade. Specifically, we estimate the relative incidence of changes in workers’ employment status with regard to sector, firm, occupation and region. We relate the incidence of adjustment to a range of labour market characteristics and indicators of trade exposure. Our findings are not consistent with the notion that there is a systematic relationship between the type of trade expansion (inter- or intra-industry) and the type of employment adjustment (within or between industry adjustment) or that there is less labour market adjustment associated with intra- than inter-industry trade.     

Does North-South horizontal intra-industry trade really exist? An analysis of the toy industry

Does North-South Horizontal Intra-Industry Trade Really Exist? An Analysis of the Toy Industry. — In a combination of a case study approach and econometric analysis, bilateral intra-industry trade between high income countries and low income countries in the toy industry is investigated. In a number of products there is important bilateral intra-industry trade between both groups of countries. Econometric analysis in which a number of the explanatory variables used were quantified on the basis of the information supplied by the industry-spokesmen yields results which strongly support the view that the bilateral IIT between the high income countries and the low income countries in the toy industry is determined significantly by horizontal product differentiation and economies of scale.     

International intra-industry trade of China

International Intra-Industry Trade of China. — The purpose of this paper is to measure the extent of the international intra-industry trade of China, and to test empirically various country-specific and industry-specific hypotheses concerning the determinants of vertical and horizonal intra-industry trade between China and her major trading partners. It is revealed that China has possessed the prerequisite of intra-industry trade and that China’s intra-industry trade follows similar patterns of those in developed countries as China is moving towards a market-oriented economy.

Intra-industry trade of India: Trends and country-specific factors

Intra-industry Trade of India: Trends and Country-Specific Factors. — The analysis in this paper confirms that trade liberalization biases trade expansion towards intra-industry trade (IIT) in India. The increased level of IIT is largely exportled, that is, caused by a faster growth of exports than of imports. India’s IIT is more intense with high-income countries and is characterized by a greater extent of complementarity. Further, certain country-specific factors which are found to be crucial in the models of vertical IIT are pertinent in influencing the pattern of India’s bilateral IIT.     

Static and dynamic measurement of intra-industry trade and adjustment: A geometric reappraisal

Static and Dynamic Measurement of Intra-Industry Trade and Adjustment: A Geometric Reappraisal. — The principal analytical device used is an industry “trade box” that allows the authors to geometrically examine changes in intra-industry trade (ITT), total trade (TT), net trade (NT) and the Grubel and Lloyd (GL) index as a result of movements in trade points. The authors propose an approach to measure changes in both the absolute and relative valuesof ITTand NT with respect to changes inTT. Their methodology highlights a number of weaknesses with the existing literature on marginalIIT and provides a methodology that can be applied to investigate adjustment implications of changing patterns and levels of intra-industry trade.     

The Skill Content of Inter- and Intra-Industry Trade: Evidence for the United Kingdom

In this paper we investigate the relative importance of net exchanges of skills embodied in intra-industry and inter-industry trade for the UK’s trade with some middle income countries. We also separately measure the net exchanges of skills embodied in vertical and horizontal intra-industry trade (IIT). We find that there are substantial factor exchanges involved in IIT, implying that traditional factor content studies may have seriously underestimated the actual factor content of total trade flows. This means that the adjustment effects of IIT may be greater than is often presumed. We also find, in line with theory, that vertical IIT involves similar net exchanges of labour of different skills to that of inter-industry trade, while horizontal IIT involves much smaller net exchanges of skills.

The role of comparative advantage in trade within industries: A panel data approach for the European Union

The Role of Comparative Advantage in Trade within Industries: A Panel Data Approach for the European Union. — A large share of EU member states trade is intra-industry trade (IIT) in the period 1985-1996; in particular, IIT is based on products differentiated in quality (vertical IIT). Moreover, exports from southern countries are located mainly at the lower end of the price-quality spectrum, whereas those countries with higher per capita incomes are located at the higher end. According to the vertical IIT models, we hypothesize that commercial specialization of members states over the quality spectrum within industries is explained by differences in technological, physical and human capital. The results show that comparative advantage is an important driver of the pattern of European trade within industries.     

Entrepreneurship and intra-industry trade

Entrepreneurship and Intra-Industry Trade. — The paper introduces entrepreneurs into the theories of intra-industry trade and investigates the role of a country ’s “entrepreneurship” in international trade. It is shown that therelative entrepreneurship between countries determines the terms of trade but the welfare effects are not obvious. Among other things, it is found that (1) an increase in exports improves the terms of trade and (2) an increase in country size is not always beneficial.     

On the measurement of product quality in intra-industry trade: An empirical test for China

A relatively recent development in the intra-industry trade (IIT) literature is the measurement of the simultaneous import and export of quality-differentiated products, commonly known as vertical and horizontal IIT. A recent paper from Azhar and Elliott [Azhar, A. K. M. & Elliott, R. J. R. (2006), On the Measurement of Product Quality in Intra-Industry Trade, Review of World Economics, Vol 142 no 3, pp 476–495] analyses various approaches for disentangling vertical and horizontal IIT and suggests a complementary methodology. To investigate the robustness and sensitivity of the existing approaches we examine data on the nature of trade flows between China and its East Asian neighbours and show that in 2002 China tended to export low quality versions of its manufactured goods to Malaysia, Thailand and the Philippines.     

Intra-industry trade — An in-depth study of Swedish liquid pump trade

Intra-Industry Trade — An In-Depth Study of Swedish Liquid Pump Trade. - The issue of intra-industry trade is here investigated through an in-depth case study of Swedish trade in pumps. A questionnaire was made in order to give detailed information about the trade flows. The survey indicates that the share of “true” IIT in Sweden's centrifugal pump trade in 1990 was about 10 percent. This part of the apparent IIT could not be attributed to “categorical aggregation”. The survey revealed twelve different causes of IIT. A large share of IIT was due to re-exports (= vertical IIT). Behavioural and institutional factors were the main explanations of the non-re-exports IIT (= horizontal IIT).     

On the Measurement of Product Quality in Intra-Industry Trade

The world has witnessed a dramatic increase in trade over the last forty years. Much of this growth in trade is intra-industry in nature. A relatively recent development in the intra-industry trade (IIT) literature is the measurement of the simultaneous import and export of quality-differentiated products, commonly known as vertical and horizontal IIT. In this paper we compare the Greenaway, Hine and Milner (1994) and Fontagné and Freudenberg (1997) approaches to disentangling vertical and horizontal intra-industry trade and examine some of the implications of employing simple ratios to define the boundary between product quality types. We present a complementary approach based on the traditional Grubel and Lloyd (GL) index and demonstrate with numerical examples its versatility and applicability at the product level. JEL no.
