Social interactions are widely understood to influence consumer decisions in many choice settings. This paper identifies causal peer effects in water conservation during the growing season, utilizing variation from consumer migration. We use machine learning to classify high-resolution remote...

Intensive promotional marketing campaigns can be used to introduce products to consumers with the goal of increasing awareness, consideration, purchase, and word-of-mouth (WOM). In this paper, we study the role of campaign duration on solar photovoltaic adoption using a large-scale field...

A growing literature points to the effectiveness of leveraging social interactions and nudges to spur adoption of pro-social behaviors. This study investigates a large-scale behavioral intervention designed to actively leverage social learning and peer interactions to encourage adoption of...

The underlying channels through which peer influence operates in durable good adoption can affect the ability of marketers to leverage them. In this paper, we assess whether the visibility of peers' adoption decisions leads to greater peer influence. The context we study is residential rooftop...

We review literature on several types of energy efficiency policies: appliance standards, financial incentive programs, information and voluntary programs, and management of government energy use. For each, we provide a brief synopsis of the relevant programs, along with available existing...

The economics of climate change involves a vast array of uncertainties, complicating both the analysis and development of climate policy. This study presents the results of the first comprehensive study of uncertainty in climate change using multiple integrated assessment models. The study looks...

The solar photovoltaic (PV) industry in the United States has been the recipient of billions of dollars of subsidies, motivated both by environmental externalities and spillovers across firms from learning-by-doing (LBD) in the installation of the technology. Using a dynamic model of demand and...

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...
