Recent findings on limited financial literacy and exponential growth bias suggest saving decisions may not be optimal because such decisions require an accurate understanding of how current contributions can translate into income in retirement. This study uses a large-scale field experiment to measure how a low-cost, direct-mail intervention designed to inform subjects about this relationship affects their saving behavior. Using administrative data prior to and following the intervention, we measure its effect on participation and the level of contributions in retirement saving accounts. Those sent income projections along with enrollment information were more likely to change contribution levels and increase annual contributions relative to the control group. Among those who made a change...
January 2012Impacts of Unionization on Employment, Product Quality and Productivity: Regression Discontinuity Evidence From Nursing Homes
with Robert J. Town, David C. Grabowski, Michelle M. Chen: w17733
This paper studies the effects of unions in private-sector nursing homes on a broad range of labor, firm, and consumer outcomes.
