Research Overview

The diversity of individual's economic circumstances is occurred due to not only their own decision but also exogenous shocks such as illness or unemployment. Observing the inequality in temporary economic states could not shed light on the comprehension of the inequality in lifetime welfare. On the other hand, observing the transition of aggregate economic valuables would overlook the heterogeneity of individual welfare. Designs of public policy require an overall comprehension of varied individuals facing different economic circumstances at different life stages.
The subjects of the research are the heterogeneity in individual attributes that can change during one's lifetime, such as economic ability, health status, or family arrangements. In general, redistribution policy for equalizing the economic results has a negative effect on individuals' efforts. When, however, individuals confront undiversified risk, redistribution policy also has a function as insurance system by dispersing the risk among many individuals. Therefore, redistribution policy could also encourage individuals' making an effort to achieve better economic results. Balancing these two effects of redistribution policy on individual decisions is required for the current public policy.
