To this end, we conducted a randomized controlled trial in 42 villages in Thailand to test a novel intervention that combines commitment contracts for smoking cessation with team incentives that activate peer pressure. We randomly assigned 201 participants, 11% of all smokers in the study area, to a control group that received smoking cessation counseling or a treatment group that received counseling plus a commitment contract, team incentives, and text message reminders for smoking cessation. We find that, relative to the control group, the intervention increased biochemically verified smoking abstinence by 25% points at six months (three months post-intervention). Moreover, the intervention cost about
