Effect of multilateral trade liberalization on services export diversification

PurposeThis study investigates the effect of multilateral trade liberalization on services export diversification with a view to complementing the recently published work on the effect of multilateral trade liberalization on export product diversification.Design/methodology/approachThe empirical exercise been performed using a panel dataset of 133 countries over the period 1995–2014.FindingsThe findings show that multilateral trade liberalization is associated with greater services export diversification in both developed and developing countries alike. This is particularly the case in countries with a high reliance on manufactured goods exports or those that enjoy greater export product diversification. Interestingly, multilateral trade liberalization enhances services export diversification in countries that experience higher foreign direct investment inflows.Research limitations/implicationsThese findings highlight the importance of multilateral trade liberalization for services export diversification. The study has considered explicitly supply-side factors that could affect services export diversification. This is because the indicator of multilateral trade liberalization is highly correlated with some demand-side factors, such as the world demand for services exports. Therefore, another avenue for future research could involve looking at the demand side factors that could influence services export diversification, and whether the degree of multilateral trade liberalization matters for the influence of these demand factors on services export diversification.Practical implicationsThe current study through its positive effect on both export product diversification and services export diversification, greater cooperation among World Trade Organization (WTO) Members on trade matters could help revive economic growth, particularly in the current COVID-19 pandemic that has significantly plummeted it.Originality/valueTo the best of our knowledge, this is first study that has investigated this issue.

Services export diversification and services export revenue stability: does trade openness matter?

PurposeThe international trade literature has established that export product diversification lowers export product revenue instability. The current analysis investigates whether this finding carries over services exports.Design/methodology/approachThe empirical analysis covers a sample of 152 countries over the period 1980–2014 and employs the two-step system generalized method of moments (GMM) approach.FindingsThe empirical findings indicate that services export diversification reduces services export revenue instability both over the full sample as well as over sub-samples of high-income countries (HICs), least developed countries (LDCs) as well as developing countries (i.e. non-HICs) that are not LDCs. HICs appear to experience a higher positive effect of services export diversification on services export revenue instability than in developing countries. The analysis also shows that countries that further open-up to international trade enjoy a greater reducing effect of services export diversification on the instability of services export revenue.Research limitations/implicationsThis analysis, therefore, adds to the existing studies on the relationship between export product diversification and the instability of revenue derived from goods exports by focusing on the services export side. An important message from the analysis is that countries that diversify their services export basket enjoy lower services export revenue instability when they further integrate into the world trade market.Practical implicationsThis study highlights the importance of services export diversification, including for stabilizing services export revenue to services traders. Diversifying services export items, including across traditional and modern services sectors involves the implementation of a wide range of policies and measures, of which the liberalization of the services sectors through reduction and eventually the elimination of services trade barriers; the improvement of the business environment and the development of domestic financial markets (see for example, Hoekman, 2017). It could be interesting that another study consider policies and measures that could promote services export diversification.Originality/valueTo the best of the authors’ knowledge, this is the first time this topic is being addressed, including empirically.

Effect of Export Product Quality on Export Product Diversification at the Extensive Margins

This paper explores the effect of improvement in export product quality on export product diversification at the extensive margins. The analysis relies on a sample of 135 countries (both developed and developing countries) over the period 1970-2014. It uses the two-step system Generalized Methods of Moments (GMM) estimator to perform the empirical exercise. Results show the existence of a non-linear effect of export product quality on export product diversification at the extensive margins: improvement of export product quality in countries with low levels of export product quality leads to greater export product diversification at the extensive margins. However, countries with a high quality of export products experience greater export product concentration at the extensive margins. The SE findings have policy implications discussed in the conclusion section of the paper.

Explaining Trends and Factors Affecting Export Diversification in ASEAN and SAARC Regions: An Empirical Analysis

This paper examines the role played by country-specific factors in the determination of export product diversification process. To meet this objective, the paper begins by constructing a time series data for export diversification using the Herfindahl index. Then, it applies the fully modified OLS co-integration model to a panel of selected ASEAN and SAARC countries to find out the main determinants of export product diversification. Export diversification pattern shows that since the mid-1980s the ASEAN countries have continuously witnessed export diversification and the SAARC countries embarked on export diversification journey since the early 1990s. Analysis of the determinants suggests that foreign direct investment, domestic investment, competitiveness, real depreciation of domestic currency, financial sector development and institutional strength are significantly and positively related to export product diversification in both regions. These findings have important policy implications for the two regions. They call upon the policymakers for further diversification of exports, especially in the areas of their specialization that are vital for their smooth and sustained foreign exchange earnings as well as economic development. The study also recommends improving international competitive strength via improving business environment to achieve the goal of export product diversification.
