For more than forty years analysts have pointed out that society might be too slow in adopting energy efficiency technologies, a phenomenon known as the Energy Efficiency Gap. There are persistent market barriers that impede these efforts. Eliciting these barriers and their heterogeneity is key...

A central question in the analysis of fuel-economy policy is whether consumers are myopic with regards to future fuel costs. We provide the first evidence on consumer valuation of fuel economy from a natural experiment. We examine the short-run equilibrium effects of an exogenous restatement of...

This paper shows that firms respond strategically to ENERGY STAR, a voluntary certification program for energy-efficient products. Firms offer products that bunch at the certification requirement, differentiate certified products in energy and non-energy dimensions, and charge a price premium on...

A coarse certification provides simple, but incomplete information about quality. Its main rationale is to help consumers trade off dimensions of quality that are complex and lack salience. In imperfectly competitive markets, it may induce excess bunching at the certification requirement, crowd...

The behavioral responses to taxes and subsidies are often subject to various behavioral biases and transaction costs - what we define as "microfrictions". We develop a theoretical framework to show how these microfrictions - and their heterogeneity across the population and policy instruments -...

We estimate whether consumers respond to local energy costs when purchasing appliances. Using a dataset from an appliance retailer, we compare demand responsiveness to a measure of energy costs that varies with local energy prices versus purchase prices. We strongly reject that consumers are...

Quantifying heterogeneity in consumers' misperceptions of product costs is crucial for policy design. We illustrate this point in the energy context and the design of Pigouvian policies. We estimate non-parametric distributions of perceptions of energy costs in the U.S. appliance market using a...
