Instruments chosen to pursue climate related targets are not always efficient. In this paper we consider an economy with three climate related targets for its electricity generation: a given share of “green” electricity, a given expansion of “green” electricity, and a given reduction of...

In this paper, we study regulation of externalities involving many small-scale polluters, where the damages from emissions depend on the polluters' locations. Examples include nutrient and pesticide emissions from farms, particulate emissions from vehicles and home heating units, emissions of...

The paper analyzes the problem of achieving a target path of emission reductions in the electricity sector, using a scheme of tradable green certificates (TGC). There are two types of generation, renewable and fossil. The latter causes the emissions. The paper also examines effects from emission...
