Tradable White Certificates (TWC) schemes, also labelled Energy-Efficiency Certificates schemes, were recently implemented in Great Britain, Italy and France. Energy suppliers have to fund a given quantity of energy efficiency measures, or to buy so-called "white certificates" from other...

It can be argued that one way to reduce the dependence from external energy sources, is simply to reduce the demand for energy.

This article presents an integrated assessment of climate change, air pollution, and energy security policy. Basis of our analysis is the MERGE model, designed to study the interaction between the global economy, energy use, and the impacts of climate change. For our purposes we expanded MERGE...

We compare a range of energy efficiency policies in a durable good market subject to both energy-use externalities and price-quality discrimination by a monopolist. We find that the social optimum can be achieved with differentiated subsidies. With ad valorem subsidies, the subsidization of the...
