In this article in fivebooks.com, Ian Goldin speaks about the benefits of migration although those economic benefits are often widely and differently dispersed. He points to the disconnect between the benefits of immigration and often the political downsides where some communities feel disadvantaged. He notes that the business community often calls for more migrants and refugees when politicians are moving in the opposite direction. Ian Goldin is Professor Globalisation and Development and Director of the Oxford Martin School at the University of Oxford.
