Public Pension Benefits Claiming Behavior: New evidence from the Japanese Study on Aging and Retirement

This paper explores the public pension claiming behavior of the Japanese. First, we perform financial simulations and estimate the expected utility, depicting the typical patterns of pension benefits in a lifecycle model. We show that the optimal retirement age depends on the beneficiaries' mortality risk, discount rate, initial wealth, and risk attitude. Second, we use individual-level data from the Japanese Study on Aging and Retirement to examine empirically the determinants of the take-up timing. We find supportive evidence that most of the factors examined in the simulation are indeed significantly associated with early claiming of pension benefits for wage earners.
