This excellent book is crisply and clearly written and makes a significant contribution to the fields of labor and immigration economics. It will be a go-to resource on immigration for many years to come.

This book is an excellent synthesis of a diverse set of theory and empirical work on immigration. It is well organized, with early chapters doing a good job of setting up the later ones. I have never seen a better job of bringing together such diverse topics as assimilation, selection, and labor market impacts. The author has done an effective job of simplifying the theories down to their essences; and developing equations that make the theories’ implications plain to see with simple algebra, often accompanied by a clear figure. It will be accessible and interest-provoking to graduate and advanced undergraduate students in economics.
