Migration

There has been a surge of anti-immigrant sentiment in the US and many European countries. This column uses survey results to show that accurate information about numbers of immigrants changes opinions on whether there are too many immigrants, but not on policy towards them. More detailed information on the characteristics of immigrants, however, can increase support for pro-immigrant policies, particularly among those who start off with the most negative views on immigration.

The impact of immigration on US economic development has become a controversial issue in recent policy debates. This column, arising from a study linking Federal Census data with patent records, examines the historical role of immigrant inventors in the process of US technological innovation. Immigrant inventors appear to have been of central importance to American innovation during the 19th and 20th centuries, both through their own inventive activity and through their influence on domestic inventors.

Despite numerous studies exploring how immigration affects local labour markets, there is limited evidence on the impact of immigrants on firms’ productivity levels. Using detailed, firm-level data from France, this column explores how firms react to an increase in the supply of immigrant workers. Provinces with a large increase in immigrant supply experienced higher productivity growth, especially among firms that were initially less productive. This suggests immigration can promote convergence in firm size and productivity levels.

The distribution of talent and human capital is highly skewed across the world. As high-income countries engage in a global race for talent, the resulting migration of high-skilled workers across countries tilts the deck even further. This column draws upon newly available data to outline the patterns and implications of global talent mobility. Key results include recent dramatic increases in high-skilled migration flows, particularly in certain occupations, in certain countries, among those with higher skill levels, and from a wider range of origins.

Over the past decades, economists working on growth have ‘rediscovered’ the importance of history, leading to the emergence of a vibrant, far-reaching inter-disciplinary stream of work.  This column introduces a new eBook in three volumes which examines key themes in this emergent literature and discusses the impact they have on our understanding of the long-run influence of historical events on current economics.
