Development, Trade and Migration

Development, Trade and Migration Research Group

Researchers in the Development, Trade and Migration group study how individuals, firms, bodies from the civil society and governments adjust to globalisation.

Their work considers how those groups respond to their environment to improve economic and human development, for example through investing in human capital, migrating to foreign countries, exporting their production or creating firms.
