Financial Incentives on Weight Loss
(RWI-Obesity)

The RWI – Leibniz Institute for Economic Research conducted a randomized experiment between March 2010 and July 2013. Aim of the project was to analyze if bonus payments are a good incentive to loose weight. The data set covers information on medical and socio-economic characteristics of the participants. The data are merged from administrative data, survey data and measures of doctors/pharmacists. 

The setting of the random experiment can be divided in four project phases. The first phase is the stay in a medical rehabilitation clinic, which usually lasts three to four weeks. Afterwards, the second phase, with a total duration of four months, is the weight-loss period, followed by the third phase, a six-month weight maintenance period in which the participants aim at holding their achieved weight. Finally, the experiment ends with a one-year follow-up phase.
