Economists have speculated that the welfare gains from technological innovation that reduces the future costs of environmental protection could be a lot more important than the "Pigouvian" welfare gains over time from correcting a pollution externality. If so, then a primary concern in the...

This paper presents an analytical and numerical comparison of the welfare impacts of alternative instruments for environmental protection in the presence of endogenous technological innovation. We analyze emissions taxes and both auctioned and free (grandfathered) emissions permits. We find that...

Choices in energy regulation, particularly whether and how to price externalities, can have widely different distributional consequences both across and within income groups. Traditional welfare theory focuses largely on effects across income groups; such "vertical equity" concerns can typically...
