The role of cross-border networks of skilled labor in offshore outsourcing: Empirical evidence based on the network theory

This study investigates the determinant role of the cross-border movement of skilled labor in the expansion of service trade between the U.S. and both developed and developing countries. For this purpose, we employ the key concepts of network theory as an analytical framework and conduct panel data analysis and graphical modeling analysis for 31 countries from 1999 to 2008. In this decade, offshore outsourcing in the service trade took off worldwide. We use data for each country’s service exports to the U.S., number of H-1B visas issued, GNI per-capita, network readiness index, and an English dummy for the official language. We illustrate the trajectory and interactions between these factors. These analyses yield three observations. First, service trade with the U.S. is more intensive among higher income countries. Second, the number of H-1B visas issued has a positive effect on service exports to the U.S. Third, individuals in lower-income countries tend to desire H-1B visas and create intensive skilled labor networks with the U.S., the path through which developing countries such as India expanded their service exports to the U.S.
