Social interaction (peer) effects are recognized as a potentially important factor in the diffusion of new products. In the case of environmentally friendly goods or technologies, both marketers and policy makers are interested in the presence of causal peer effects as social spillovers can be...

This paper reviews the recent evidence on the effectiveness and cost-effectiveness of energy efficiency interventions. After a brief review of explanations for the energy efficiency gap, we explore key issues in energy efficiency evaluation, including the use of randomized controlled trials and...

Observability has been demonstrated to influence the adoption of pro-social behavior in a variety of contexts. This study implements a field experiment to examine the influence of observability in the context of a novel pro-social behavior: peer-to-peer solar. Peer-to-peer solar offers an...

Per the National Academy of Sciences’ 2017 recommendations, the social cost of carbon (SCC) is now calculated with a modular framework in which researchers can easily substitute different models for estimating climate damages. The modular approach is an improvement from previous practice, but...

There is strong evidence on the mortality and morbidity external costs of air pollution. This paper focuses on another source of air pollution externality: the loss in solar electricity generation from increased atmospheric opacity due to air pollution. We use data from residential rooftop solar...

Product complementarities can shape market patterns, influencing the demand for related products and their accessories. This study examines complementarities in the demand for rooftop solar and an accessory, battery energy storage. Using nationwide administrative data, we estimate a dynamic...
