This paper investigates the idea that people are unsure about the value they place on prospective changes in environmental goods. In particular, we focus on a parametric explanation of the determinants of a "value gap," the difference between the most someone is sure they would pay for an...

Recent literature on greenhouse gas controls shows the costs of climate protection can be offset by the ancillary benefits generated from lower local air pollution. We show here that such ancillary benefits imply the unfettered price of carbon emissions permits observed in tradable permit...
