The failure of consumers to make seemingly cost-effective investments in energy efficiency is commonly referred to as the energy efficiency gap. We review the most recent literature relevant to the energy efficiency gap and in particular discuss what the latest insights from behavioral economics...

Energy efficiency and conservation are considered key means for reducing greenhouse gas emissions and achieving other energy policy goals, but associated market behavior and policy responses have engendered debates in the economic literature. We review economic concepts underlying consumer...

We analyze the cost-effectiveness of electric utility rate payer–funded programs to promote demand-side management (DSM) and energy efficiency investments. We develop a conceptual model that relates demand growth rates to accumulated average DSM capital per customer and changes in energy...

Despite several decades of government policies to promote energy efficiency, estimates of the costs and benefits of such policies remain controversial. At the heart of the controversy is whether there is an "energy efficiency gap," whereby consumers and firms fail to make seemingly positive net...

We analyze the cost-effectiveness of electric utility ratepayer-funded programs to promote demand-side management (DSM) and energy efficiency (EE) investments. We specify a model that relates electricity demand to previous EE DSM spending, energy prices, income, weather, and other demand...

Environmental policy analyses often draw on stated preferences, with most humans having strong preferences with respect to how we view ourselves and how we would like others to perceive us. This may create systematic differences between reported and real behavior, making policy analysis based on...

This essay was prepared as part of a workshop on carbon capture and sequestration held by the International Risk Governance Council (IRGC) in Washington, DC, from March 15–16, 2007. The goal of the workshop was to bring together researchers, practitioners, and regulators from Europe, the...

This chapter provides an economic perspective of environmental law and policy with regard to both normative and positive dimensions. It begins with an examination of the central problem in environmental regulation: the tendency of pollution generators in an unconstrained market economy to...

This article, prepared for the forthcoming second edition of the New Palgrave Dictionary of Economics, provides an overview of the economics of environmental policy. Included are the setting of goals and targets, notably the Kaldor-Hicks criterion, and the related method of assessment known as...

We present a model for an energy market that includes a green certificate for suppliers of energy from renewables and a purchaser commitment to buy these certificates. We show that price and volume effects in the energy market are ambigous under a wide range of alternative levels of the...
