Evolving Migrants: How Family Migration Shapes Economy and Society in Japan (2020_1_40_011)


An important issue in policy debates regarding international migration is how the profit & loss from immigration is being broadly shared. The profit & loss crucially relates to household structures of foreign populations, which might change over time. The aim of the "evolving migrants" project is to study the transition from the influx of single migrant workers to the immigration of families and the household formation of immigrants. However, family migration broadly affects the economy and society in host countries, and it is not clear how changes in household characteristics of foreign populations affect profit & loss from immigration. The project empirically characterizes changes and diversity in the household behavior of foreign workers in Japan over the last four decades. The project also theoretically develops a collective household model of foreign populations so as to understand the impacts of the rise of foreign populations from following the channels of household decision-making: bargaining?, intrahousehold resource allocation, the outsourcing of home production, housing, location decisions, consumption, childcare, education, or cultural production. Our alternative model incorporates these realistic and multi-dimensional features of longer-term household decisions of foreign populations. To contribute to Japan’s immigration policy, we combine qualitative analysis with quantitative research examining how family migration reshapes the economy and society.
