The recent global migration pattern indicates the importance of the movement of people from developing countries to developed countries in search of better economic opportunities. The G20 report of ‘International Migration and Displacement Trends’ mentions India at the top of the list of highly educated emigrants in G20 countries. The current study addresses the endogeneity problem in the migration determinants and attempts to highlight the major regional and economic determinants of migration flow from India to major OECD countries using the Gravity model of migration. We apply the Prais–Winsten regression method to address the cross-sectional correlation, while we apply instrumental variable regression and Hausman–Taylor regression estimation techniques to deal with the endogeneity issue. The findings reveal that the population of India, distance, common official language and per capita income differential are the major determinants of migration from India. In the backdrop of our findings, in terms of per capita income differential, there is a need for an upward revision in the pay scale of the white-collar workers in the organised sector.

The main objective of this article is to showcase the major activities/processes each exporter/importer needs to go through in any land port, seaport or airport. The article looks into the processes, time taken during various processes, the perceptions of stakeholders about the extent of challenges they face during these processes and the logistics costs. Finally, the article provides a comparison across exporting ports in terms of their efficiency in clearing cargo. However, we have also attempted to measure of the efficiency of the port in terms of cargo offloading. JEL Codes: P45, R41, R48, Q37

This article aims to explore the asymmetric influence of real exchange rate volatility on India–US trade commodity-wise. In this study, the assumption of symmetric relation is neglected and assessed on the asymmetric effect of real exchange rate volatility on 90 commodities distributed under 6 industries. This study verifies short-run and long-run asymmetry effects, the short-run effect in 21 Indian exporting commodities and 19 Indian importing commodities. However, the short-run effect lasting onto the long run in 16 exporting commodities and 27 importing commodities strongly supports the J-curve. Also, non-linear causality is witnessed in this study running from real exchange rate variability to export trade and import trade. The empirical analyses explain that commodities will benefit the export or import growth with the depreciation of exchange rate or discouraging with the appreciation of exchange rate. The findings of the study provide a view for policy making. JEL Codes: C22, F1, F14, F31, O19

Foreign direct investment (FDI) improves economic growth by stimulating native investment, facilitating technology transfers in the recipient country and increasing human capital development, thus playing a vital role in economic development. On the other hand, innovation is also considered one of the major drivers for the economic growth of a country. This study empirically investigates the impact of FDI and its absorption capacity on the national innovation system of the world’s top five largest FDI recipient countries for the period of 1990–2016. Using two-stage analysis (DEA and Tobit regression), we found that research and development expenditures, researchers in the host country and the number of patents, trademark and industrial design applications are positive drivers of the national innovation systems. Moreover, the FDI inflows positively impact the innovation efficiency in the host countries. However, the strength of this relationship depends on the availability of the absorption capacity of FDI in the host country. The result shows that the global financial crisis and inflation negatively impact the FDI inflows and innovation efficiency in the sample countries. It concludes that FDI inflows and the country’s strength of domestic absorption capacity are essential drivers for developing national innovation ecosystems. JEL Codes: F1, F4, G10, M21

This study, by employing an augmented gravity model under the Poisson pseudo-maximum-likelihood (PPML) estimation, aims to scrutinise the determinants and potential of seafood exports from Vietnam—a transitional and emerging economy to the global market over the period of 2000–2018 at both aggregate and sectoral levels. With remarkable growth over the years, Vietnam has become the largest seafood exporter in Southeast Asia. The country’s seafood exports have been diversified in terms of export structure and export markets. The estimation results show that the size of economies and market development from importers are the main factors that are driving Vietnam’s total seafood exports. At the sectoral level, the magnitude of the effects of income per capita significantly differs among the subsectors of seafood. We find that the impacts of factors such as region, access to the World Trade Organization (WTO) and the free trade agreement (FTA) establishment on Vietnam’s seafood exports are heterogeneous. We found that there is still room for the expansion of Vietnam’s seafood exports to some market destinations. This article suggests a dynamic strategy to increase Vietnam’s seafood exports in the coming years. JEL Codes: F1, F14, Q1

In this article, we examine the Indian garment industry to examine the effect of clusters on the sales of this industry. The data has been collected through a primary survey in five garments clusters in India. The variable that is significant in explaining sales in most equations is technology proxied by imported machinery. It has been argued that inter-firm linkages and linkages between firms, service providers and institutions are crucial for competitiveness and this is best achieved through a cluster. Studies on clusters have shown that some clusters have been able to deepen their inter-firm division of labour, raise their competitiveness and break into international markets. The development of the cluster in India has followed the ‘top-down’ approach and the natural process through which linkages are developed are yet to occur in most clusters. JEL Codes: F14, L67, L23

This article empirically explores the key drivers of export diversification in a large panel of 101 countries consisting of 43 high-income, 47 middle-income, and 11 low-income countries from 1995 to 2019. Considering the fractional nature of the dependent variable (Herfindahl-Hirschman Index), the estimates are obtained using the fractional logit technique with a set of potential determinants of export diversification for all country samples and three sub-samples. The results reveal that human capital accumulation, GDP per capita, population, trade openness, the share of manufactured output to GDP, and FDI are important determinants of export diversification. However, the share of agriculture to GDP and official exchange rate promotes export concentration. Contrary to our all-country estimation, GDP per capita and population act as deterrents to export diversification in low-income countries. In addition, the results show that the value-added in agriculture plays a dominant role in strengthening the export structure of high-income countries. Our findings suggest that policymakers should implement and reform policies targeting human capital accumulation, trade openness, investment, and value addition in the manufacturing sector for diversifying the export structure.

This study argues that post-pandemic world may not necessarily follow the usual mechanism of trade. In fact, recent pandemic dragged down us to the trajectory of new normalcy. Economic behaviour under new normalcy has changed immensely following several distorted effects, namely preference distortion and information asymmetry. Such distortions change trade posture via gains from trade arguments under comparative advantage. Using the traditional Ricardian model with two countries, two goods and one factor, this study explores the effect of changes in consumer preferences on trade patterns based on comparative advantage and the significance of eliminating information uncertainty. To retain the pre-pandemic gains from such trade this study advocates for consideration of information cost associated with trade basket along with innovation. These results could be important for policymaking at least in post pandemic regime. Sensitivity analysis has also been constructed to capture the extent of changes in trade–autarky profit gaps. This study builds on the verge of economic crisis linking to pandemic and international trade. JEL Codes: C70, D81, F11, L15
