Determinants of Export Diversification Around the World: 1962–2000

Using a large dataset for 79 countries covering the period 1962–2000, this study analyses the main determinants of export diversification (concentration). We explore the role of several factors and we use three different indicators of export concentration. We find robust evidence across specifications and indicators that trade openness induces higher specialisation. In contrast, financial development does not seem to help countries to diversify their exports. Looking at the effects of exchange rates, in some of the results, a negative effect of real exchange rate volatility on export diversification is detected, but no significant effects of exchange rate overvaluation. There is also evidence that human capital accumulation contributes positively to diversify exports and that increasing remoteness tends to reduce export diversification. We also explore the role of terms of trade shocks. Most of the results suggest an interesting interaction between this variable and human capital: improvements in the terms of trade tend to concentrate exports, but this effect is lower for those countries with higher levels of human capital. This evidence suggests that countries with higher education can take advantage of positive terms of trade shocks to increase export diversification.     

EXPORT DIVERSIFICATION IN LATIN AMERICA AND THE CARIBBEAN

Beginning in the mid-1980s the primary development paradigm pursued by Latin American and Caribbean countries undertook a major shift from the concept of import-substitution-industrialization (ISI) to that of export-led growth and openness to international markets. Despite these efforts, virtually no research has been undertaken to assess the degree to which the export structures of Latin American and Caribbean countries have in fact diversified. This is unfortunate as the trade policy environment facing these countries is poised to undergo significant changes. The purpose of this article is to examine the structure of exports to the United States from 19 selected Latin American and Caribbean countries over the 1989 to 2000 period to assess the degree to which export diversification has occurred. The analysis is conducted at a reasonably disaggregate level using 2-digit HTS data. The countries included in the analysis provide a very interesting mix of commonalities and differences. The results suggest wide differences in the degree of diversification exhibited and suggest that these differences are related to economic size and social capability.     

Domestic Credit and Export Diversification: Africa from a Global Perspective

ABSTRACT

As open economies, African countries need to diversify their exports for economic transformation, sustained growth, and development. Meanwhile, there has been increasing importance of development financing. Following the discussion of theoretical issues on the importance of domestic credit as a potential instrument for overcoming the liquidity constraint of developing countries, as in the case of Africa, this paper empirically explores the determinants of export diversification, with particular attention to domestic credit. The estimation is based on a five-year panel regression analysis for the 1962–2010 period involving 80 countries around the world, of which 62 are developing and 29 African countries, using as covariates variables traditionally viewed as affecting export diversification. System GMM estimates provide robust evidence supporting the importance of domestic credit for African countries, while its role in other countries seems rather marginal. In addition, human capital in the form of schooling, governance as measured by constraint on the chief executive of government, and being land-locked, all exert significant effects, as anticipated, on export diversification among African countries. However, except for governance, appropriately controlling for the interactive effect of domestic credit with ‘Africa’ yields generally insignificant impacts of these variables, together with domestic credit, on export diversification in non-African countries. These results point to the dominant role of domestic credit in Africa vis-à-vis other countries globally.     

Aid for trade and export diversification in recipient‐countries

The Aid‐for‐Trade (AfT) Initiative was launched by the Members of the World Trade Organization (WTO) with a view to helping developing countries and the least‐developed countries (LDCs) expand their trade. The current paper contributes to the literature on AfT effectiveness by examining how AfT affects recipient‐countries' export product diversification. The analysis has been carried out on a sample of 104 AfT recipient‐countries over the period 2002–2015 and uses the two‐step system generalised methods of moments (GMM) approach. Results show that AfT flows are conducive to export product diversification in recipient‐countries. In addition, the analysis has shown a positive impact of the cumulative AfT flows on the export product diversification path of these countries. These results apply as well to the subsamples of LDCs and other developing countries. One policy implication of these results is that a scale‐up of AfT would help recipient‐countries to diversify their export products baskets and hence facilitate their greater integration into the global trading system.     

Effects of export product diversification on quality upgrading: an empirical study

This paper empirically examines the effects of export product diversification on overall export quality in a panel data set of 115 countries from 1970 to 2010. It uses the data sets of the overall export quality and three export diversification measures of the International Monetary Fund: the extensive margin (variation in the number of new products exported), the intensive margin (variation in export values among existing exports), and the overall (Theil) index. It finds that export quality has only been increasing with a higher variation in export values among existing exports in low- and lower-middle-income countries. It also observes that export quality has been increasing with both a higher variation in export values among existing exports and new products exported in upper-middle- and high-income countries. The results are robust to the changing measures of controls in the benchmark model, the inclusion of many other controls; i.e. various measures of globalization, country size, factor endowments, macroeconomic stance, etc., and the exclusion of outliers.

Agricultural Export-Diversification and Economic Growth in Caribbean Countries: Cointegration and Error-Correction Models

This article uses cointegration and error-correction models to analyze the causal relationship between agricultural export diversification and economic growth in eight selected Caribbean countries using annual data from 1961 to 2000. The empirical results show that in the short run, agricultural export diversification Granger causes economic growth in Barbados and Belize. Noncausality exists for the other countries. In the long run, agricultural export diversification also Granger causes economic growth in the Dominican Republic. On the contrary, agricultural export diversification is the outcome of the economic growth process in Belize, Costa Rica, Haiti, and Jamaica, in the long run. Noncausality exists in Trinidad and Tobago. There is no evidence of bi-directional causality in any of the countries in either the short or long run.     

EU Trade Preferences and Export Diversification

Since at least the 1960s, the European Union (EU) has offered various kinds of non‐reciprocal trade preferences for developing countries. Originally, these trade preferences had at least two policy goals: (i) to increase export volumes for developing countries and thereby boost their export earnings and (ii) to facilitate export diversification. While extensive research has confirmed that the first of these goals is typically met, the second goal seems to have been largely forgotten by researchers as well as in policy circles. The aim of this paper was therefore to analyse the impact of the EU's non‐reciprocal trade preferences for developing countries on export diversification. Our estimation results suggest that some trade preference programmes, such as the Generalised Scheme of Preferences (GSP), lead to increasing ranges of export products. By contrast, preferences offered to Mediterranean countries typically have no significant effects, and African, Caribbean and Pacific (ACP) preferences actually have negative effects towards the end of our time period, suggesting that ACP countries may respond to preferences by specialising into fewer goods.     

非互惠的零关税待遇是否促进了受惠国的出口多样化——基于中美对非洲贸易政策的比较研究

非互惠的优惠贸易待遇是世界贸易组织和国际社会支持发展中国家尤其是最不发达国家发展的重要工具。为了评估该政策的效果,本文以中美对非洲实施的零关税待遇为例,采用2001—2017年HS8位贸易数据从整体、行业和区域层面评估了两种政策对受惠国出口多样化产生的影响。结果显示,美国零关税待遇分为AGOA-GSP和AGOA-服装两个条款,中国零关税待遇(FOCAC)在遵循WTO规则、受惠商品范围、受惠国家标准、原产地标准及政策有效期方面均优于AGOA-GSP,但在原产地标准灵活度和政策优惠力度方面低于AGOA-服装。这些特征导致三类政策对受惠国出口多样化的影响产生显著的差异。整体上,FOCAC和AGOA-服装对受惠国出口多样化均产生了显著的积极影响,而AGOA-GSP的影响不显著;行业层面,FOCAC对受惠国制造业、矿业和农业的出口多样化均产生了显著的促进作用,而AGOA的两个条款对受惠国三个细分行业出口多样化的影响均不显著;区域层面,三类政策对受惠国出口多样化的影响仅在部分区域发挥效果。     

Trade Policy and Export Diversification: What Should Colombia Expect from the FTA with the United States?

Sectoral concentration of exports has been a longstanding matter of concern for policymakers in developing countries. According to economic theory and recent empirical evidence, improved market access through trade agreements is likely to favor export diversification. In this article, it is assessed whether this has been the case for Colombian exports to the United States and whether an FTA with the United States would help Colombia diversify their exports. We find that lower tariffs have indeed favored exports of new products from Colombia. Predictions suggest that the FTA is likely to induce further diversification, but only up to a certain point.     

Intensive and extensive margins of exports: What can India learn from China?

We decompose India's export performance in manufactured products during 2000–15 into changes at the intensive and extensive margins. India's performance, along different margins, is compared and contrasted with that of China. The results show that while China outperforms India at both the margins, the gap is particularly wide at the intensive margin. Decomposition of intensive margin along quantity and price margins shows that Chinese products are generally sold cheaper than Indian products. Higher price margin, however, has not translated into high intensive margin for India due to its abysmally low quantity margin. We examine different explanations for China's superior performance relative to India, along different margins, using a gravity model. Our results suggest that China's exchange rate policy was not the prime reason for its export success. Neither do we find that FDI inflows were significant in explaining the export performance gap between them. The results show that China's export relationship bias towards high‐income partner countries holds the key in understanding its superior performance. This bias is a natural consequence of China's high degree of specialization in labor‐intensive activities. India, by contrast, due to an idiosyncratic pattern of specialisation, has failed to exploit its export potential in high income countries.     

The Extensive and Intensive Margins of Exports: The Role of Innovation

An important prediction of trade theories is that innovation can improve a country’s export performance. Using data on patents granted by the US as a proxy for innovation and data on manufacturing exports from 105 countries over the period 1975–2001, I investigate the extent to which innovation increases the number of products traded (the extensive margin) and the export value of each product (the intensive margin). The empirical results show that (i) innovation has a positive and significant effect on both the extensive and intensive margins. The intensive margin contributes 70 per cent of the effect, and the extensive margin accounts for 30 per cent. (ii) The effect of innovation on exports is stronger for low‐income countries than for high‐income countries. (iii) More innovative countries export greater quantities and charge higher prices, suggesting that innovation increases the product quality of exports.     

The African Growth and Opportunity Act (AGOA) and export diversification

This paper explores the effect of the African Growth and Opportunity Act (AGOA) on export diversification in Sub-Saharan Africa. The existing empirical studies suggest that AGOA has had a positive effect on the overall volume of trade between Sub-Saharan Africa and the United States. However, the economic development literature emphasizes the importance of export diversification for developing countries; therefore, it is important to understand the effects of AGOA on the extensive margin of trade (i.e. the number of distinct products a country exports). Our empirical results suggest that AGOA does contribute to export diversification, specifically through its apparel provision. Countries that are eligible for the AGOA apparel provision export not only more apparel products, but also more non-apparel products to the USA. Thus, AGOA contributes to export diversification at the extensive margin of trade with the USA.     

Export diversification,composition, and economic growth: Evidence from cross-country analysis

We investigate the export-growth relationship at disaggregate levels – disaggregation both at the country level and at the level of exports – focusing on the diversification and the composition of exports of countries. In a sample of 65 countries for the period 1965–2005 the dynamic panel estimation reveals that both diversification and composition of exports are important determinants of economic growth after controlling for the impacts of other variables like lagged income, investment, and infrastructure. There is a critical level of export concentration beyond which increasing export specialization leads to higher growth. Below this critical level, diversification of exports matters for gross domestic product (GDP) growth. Growth of high technology exports also contributes tothe output growth; the relationship becomes stronger for countries that have share of manufacturing exports in their total exports greater than the world average. These results are robust even when the dataset isclassified in four sub-panels based on the export-economic growth relationship.     

经济规模、贸易成本与我国钢铁行业出口的二元边际分析

根据HS八分位将钢铁行业分为204类产品,并利用我国与168个国家(地区)的1 6748个出口数据将出口分解为广度边际(EM)、集约边际(IM)、价格因子(P)和数量因子(X),从二元边际的角度分析我国钢铁产品出口增长的途径,实证表明:集约边际对钢铁出口增长的作用大于广度边际,国家间出口的差异来源于数量因子,而价格因子的国家间差异较小;此外,经济规模、经济发展水平以及贸易成本对出口边际影响显著,但影响程度具有差异性。     

出口产品多样化对行业产出波动和绩效分布的影响研究

本文通过构建出口产品多样化、产出波动和绩效分布的测算指标,利用2002-2015年的跨国企业调研数据、行业数据和出口商品数据,运用计量模型检验了出口产品多样化对行业产出波动与行业绩效分布的影响。结果表明:出口产品多样化水平的提高显著降低了行业产出波动,而在具有强比较优势的行业中,出口产品多样化对产出波动的抑制作用更为突出;行业贸易开放度越高,行业竞争程度越强,则出口产品多样化平抑行业产出波动的作用越明显;出口产品多样化水平的提高有利于促进行业内竞争,有效降低了行业绩效离散程度,而在具有比较优势的行业内,出口"自选择"效应强化了行业内的资源再配置作用,进一步降低了行业绩效离散程度;在高资本密集型行业和高贸易开放度行业中,这种促进竞争效应更加显著。     

Trade Facilitation and Export Diversification

This paper shows that improved trade facilitation can help promote export diversification in developing countries. We find that 10 per cent reductions in the costs of international transport and domestic exporting costs (documentation, inland transport, port and customs charges) are associated with export diversification gains of 4 and 3 per cent, respectively, in a sample of 118 developing countries. Customs costs play a particularly important role in these results. Lower market entry costs can also promote diversification, but the effect is weaker (1 per cent). We also find evidence that trade facilitation has stronger effects on diversification in poorer countries. Our results are highly robust to estimation using alternative dependent and independent variables, different country samples, and alternative econometric techniques. We link these findings to recent advances in trade theory that emphasise firm heterogeneity, and trade growth at the extensive margin.     

Export diversification,specialisation and inequality: Evidence from Asian and Western countries

This paper examines the dynamic effect of globalization at the disaggregated level of sectoral export diversification and manufacturing specialization on income inequality using a panel data set of 52 Asian and Western countries from 1988 to 2014. The paper uses dynamic panel data models applying the System Generalized Method of Moments (GMM) estimations that provide more accurate and better results than those obtained with static panel data models. The results suggest that there is no statistically significant relationship between manufacturing specialization and inequality while sectoral export diversification has been the driving force of inequality. For sub-groups of countries, higher sectoral export diversification increases inequality and higher manufacturing specialization decreases inequality in high-income Asian countries and European Union (EU) member states. Moreover, the study finds insignificant effects in low-income Asian countries and Anglo-Saxon countries.     

Is export promotion effective in developing countries? Firm-level evidence on the intensive and the extensive margins of exports

How effective are export promotion activities in developing countries? What are the channels through which export promotion affects firms' exports, the intensive margin or the extensive margin? Empirical evidence in this respect is scarce. We aim at filling this gap in the literature by providing evidence on the impact of export promotion on export performance using a unique firm-level dataset for Peru over the period 2001-2005. We find that export promotion actions are associated with increased exports, primarily along the extensive margin, both in terms of markets and products. This result is robust across alternative specifications and estimation methods.     

Towards a New Trade Policy Between the USA and Middle‐East Countries:Estimating Trade Resistance and Export Potential

At the time of the conclusion of free trade areas (FTAs) between the USA and Middle‐East and North African (MENA) countries, there is a lack of literature concerning the measurement of the current US export position with regards to these countries, and the US export potential in this area. From recent developments of gravity models, this paper derives an estimable equation which includes various trade resistance variables, notably border effects, multilateral resistance as well as specific bilateral effects. The model is tested in order to scrutinise the impact of these variables on US exports to MENA countries, as well as the US export potential in this area. To that end, a selection of panel data specifications is proposed, mainly Hausman and Taylor models as well as Arellano and Bond dynamic models. Results unambiguously indicate that as compared to the other OECD countries, the USA suffers from a substantial trade integration deficit with MENA countries. This is reflected by the strongly negative values of the US‐MENA bilateral fixed effects, as well as the high bilateral border effects. In addition, the estimated actual/potential US export ratio to these countries is only 0.76. Therefore, implementing an FTA between the USA and MENA countries may allow the former to progressively improve its export position in this area. This would also help MENA countries diversify their supplying sources.
