Abstract.

The Integrated Analytical Model for Household Simulation (INAHSIM) is a microsimulation model for the Japanese population that was first developed in the 1980s as a tool for household simulation. This study attempted to improve the conventional INAHSIM in order to construct a more comprehensive alternative that incorporates a larger number of social and economic elements. It also overcame the problem for simulation—the lack of kinship relations in the initial population—by imputing parent-child relationships between those parents and children who do not live together. This paper provides an overview of INAHSIM and adds certain details of the imputation that is essential for simulating the life event of “adult children resettling to care for their aged parents.” In addition, I will show the importance of the said life event in Japan by comparing the difference in the family type of elderly people between its future distribution with or without this life event. Finally, I will discuss the future possibilities for research on microsimulation models that will play an important role in policy making.
