    Kurzfassung: Laboratory experiments were conducted to investigate how private and public information affect the selection of an innovation and the timing of adoption. The results shed light on the behavioral anomaly called the "energy-efficiency gap" in which consumers and firms delay adoption of cost-effective energy and environmental innovations. The subjects chose between competing innovations with freedom to select the timing of their adoption, relying on private signals and possibly observation of their peers. When deciding whether to make an irreversible choice between safe and risky technologies, roughly half the subjects delayed adoption beyond the time indicated by equilibrium behavior-confirming the behavioral anomaly found for environmental innovations. When they did adopt, the subjects gave proportionately more weight to their private signals than to the actions of their peers, implying they do not 'herd' on the latter. Nevertheless, when the subjects observed their peers' decisions, they did accelerate the timing of their adoption despite not necessarily imitating their peers. This result occurred even when the payoffs were statistically independent, as if observing prior adoptions exerted 'peer pressure' on the subjects to act. The experimental results suggest that rapid dissemination of information about peer actions can speed up the diffusion of environmental innovations and improve selection among competing technologies

    Schlagwort(e): Graue Literatur
    Kurzfassung: Working with the Mexican Ministry of Education, this study piloted a scalable program to reduce high school dropout rates by focusing on socio-emotional skill development and mathematics tutoring. The intervention was evaluated through a randomized field experiment with more than 5,000 youths at 20 upper secondary schools in Mexico City. An intention-to-treat analysis finds some evidence that exposure to the Opportunities and Development to Avoid Risks Program increases socio-emotional skills, but no evidence that it improves math outcomes or future attendance. Likely explanations for these 0 results include low take-up and other process factors, which are document qualitatively, as well as heterogeneous treatment effects. In particular, an inverse-probability-weighted matching model is suggestive of an effect whereby some students participate actively in the program and drop out of school less often, while other students choose not to participate when given the option and actually drop out more as a result
