Would People Behave Differently If They Better Understood Social Security? Evidence from a Field Experiment
通过随机实地实验，向年长工人提供社会保障关键信息，发现这种低成本干预使一年后劳动参与率比对照组提高4个百分点。
This paper presents the results of a randomized field experiment that provided information about key Social Security features to older workers. The experiment was designed to examine whether it is possible to affect individual behavior using a relatively inexpensive informational intervention about the provisions of a public program and to explore the mechanisms underlying the behavior change. We find that our relatively mild intervention (sending an informational brochure and an invitation to a web-tutorial) increased labor force participation one year later by 4 percentage points relative to the control group mean of 74 percent.
