Diane Coyle, Professor of Public Policy at the University of Cambridge: An individual from a poor country – say, Haiti – who migrates to a richer country like the United States immediately becomes vastly more productive and earns a far higher wage than before. The individual has not changed overnight, so their skills or cultural attitudes cannot explain their improved situation. The answer must instead lie in their new country’s environment. Economists need to connect their analysis with an understanding of the political potential for change, the sociology of organizations, and the psychology of decision-making. The challenge for researchers and policymakers is to understand – in each specific context – exactly what coordination is needed to increase productivity, and what actions (and by whom) can achieve this.
