Guest-worker programs have become a popular means of meeting shortages of low and semi-skilled labour in the developed countries and rapidly growing emerging economies in the decades following the Second World War. They have relied on various forms of temporary migration schemes to meet labour shortages in agriculture, construction, manufacturing, domestic service, and other labour-intensive activities. The purpose of this project is to examine how the structure of a guest-worker program and the economic conditions in the host and source countries affect the behavior of program participants. Various aspects of this very broad problem, both from the perspective of the host and source countries, are addressed in a number of publications and working papers stemming from the project. Some of the works are listed below.
