Developing new understanding of how global talent flow impact individual and firm performance by using big data

Drawing on human capital theory, we explore the impact of global mobility on individuals and their employing firms. We also investigate the role of cultural distance between workers who move across country borders and the local culture, and the role that HRM may play to improve capitalizing on global talent mobility. We use a big data set comprising the entire population in one country, including about 30,000 expatriates from 143 countries employed by 15,000 firms, over 11 years of data covering about 100,000 observations on expatriates and 80,000 on their firms. Our findings support the existence of positive impact of global firms on performance (6.7% higher revenues after labor costs) and individuals' wages (10%–20% higher salaries). Both relationships are statistically and economically significantly influenced by cultural distance for the performance of global firms, leading to HRM implications.
