Retirement and the Evolution of Pension Structure
发现，与固定收益计划相比，固定缴费计划缺乏年龄相关激励，导致工人平均退休年龄推迟近两年，这有助于解释典型退休年龄在长期下降后近年来的上升趋势。
Abstract Defined benefit pension plans have become considerably less common since the early 1980s, while defined contribution plans have spread. Previous research showed that defined benefit plans, with sharp incentives encouraging retirement after a certain point, contributed to the striking decline in American retirement ages. In this paper we find that the absence of age-related incentives in defined contribution plans leads workers to retire almost two years later on average, compared to workers with defined benefit plans. Thus, the evolution of pension structure can help explain recent increases in the typical retirement age, after decades of decline.
