1. Do you think that international migrants self-select in a way that results in migrants having, on average, different personal characteristics than people who do not migrate? Why and what consequences would such differences or similarities have on the source and destination countries?
2. Investigate the likely demographic trends in the United States, Germany, Japan, or another country that you might be interested in and for which population forecasts are available. What effect would an increase in immigration of foreign workers have on the ratio of retired people to working people in the short run? What effect would it have in the long run?
