Social Security Pensions in Japan: A Balance Sheet Approach

Abstract

Japan is experiencing a rapid ageing of its population with a subsequent strain on its social security pensions. Despite periodic reforms over recent decades and comprehensive reforms in 2004, many outstanding issues remain. Using the balance sheet approach we show that despite its recent reforms, Japan's social security pensions face substantial excess liabilities. As well, the reforms themselves may have exacerbated the incentive-compatibility problem.
