The 15‐Hour Week: Keynes's Prediction Revisited
研究了凯恩斯关于2030年每周工作15小时的预测为何未实现，发现英国1931至2011年间预期闲暇时间增加58%，主要源于寿命延长和退休期变长，但储蓄不足阻碍了工时大幅减少。
In 1930, Keynes opined that by 2030, people would work only 15 hours per week. As such, this prediction will not be realized. However, expected lifetime hours of leisure and home production in the UK rose by 58% between 1931 and 2011, rather more than Keynes would have expected. This reflects increases in life expectancy at older ages and much longer expected periods of retirement. Leisure in retirement contributes to high life satisfaction for the elderly, but building up savings to pay for it is a barrier to working only 15 hours per week.
