Back to Work
研究了近50%退休者经历的“未退休”现象，发现绝大多数重返工作是在退休前就计划好的，而非财务冲击或规划失败所致。
Abstract This paper analyzes a puzzling aspect of retirement behavior known as "unretirement." Nearly 50 percent of retirees follow a nontraditional retirement path that involves partial retirement or unretirement, and at least 26 percent of retirees later unretire. I explore two possible explanations: (1) unretirement transitions result from failures in planning or financial shocks; and (2) unretirement transitions are anticipated prior to retirement, reflecting a more complex retirement process. I show that unretirement was anticipated for the vast majority of those returning to work, and is not a result of financial shocks, poor planning or low wealth accumulation.
