Over sixty percent of employees at a large South African company contribute the minimum rate of 7.5% to a retirement fund—far below the rate of 15% recommended by financial advisers. I use a field experiment to investigate whether providing employees with a retirement calculator, which shows projections of retirement income, leads to increases in contributions. The impact is negligible. The lack of response to the calculator suggests many employees may wish to save less than the minimum. I use a model of asymmetric information to explain why the employer sets a binding minimum.

步入退休轨道？

一家大型南非公司有超过 60% 的员工向退休基金缴纳了 7.5% 的最低比率——远低于财务顾问建议的 15% 的比率。我使用现场实验来调查为员工提供退休计算器（显示退休收入预测）是否会导致缴费增加。影响可以忽略不计。对计算器没有反应表明许多员工可能希望储蓄低于最低限额。我使用了一个信息不对称模型来解释为什么雇主设置了一个有约束力的最低限度。
