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...

Re-orienting current energy systems toward a far greater reliance on technologies with low or no carbon dioxide emissions is an immense challenge. At the broadest level the histories presented here are very much consistent with widely held views within the energy innovation policy literature. In...

Recent efforts to endogenize technological change in climate policy models demonstrate the importance of accounting for the opportunity cost of climate R&D investments. Because the social returns to R&D investments are typically higher than the social returns to other types of investment, any...

We review what is known about the economic efficiency of fuel taxes relative to efficiency standards aimed at mitigating environmental externalities from cars. We present a simplified model of car choice that allows us to emphasize the relationships between fuel economy, other car attributes,...

This paper discusses fuel economy regulations in the United States and other countries. We first describe how these programs affect fuel use and other dimensions of the vehicle fleet. We then review different methodologies for assessing the costs of fuel economy regulations and discuss the...
