Allowing emissions permits to be banked and borrowed over time can yield efficiency gains. I develop a model to demonstrate that banking and borrowing can also be allowed for a price policy. I compare expected welfare between price and quantity policies, with and without banking, under several...

A large literature examines the interaction of private and public funding of public goods and charities, much of it testing if public funding crowds out private funding. This paper makes two contributions to this literature. First, the crowding out effect could also occur in the opposite...

Investments in energy efficiency entail uncertainty, and when faced with uncertainty consumers have been shown to behave according to prospect theory: preferences are reference-dependent and exhibit loss aversion, and probabilities are subjectively weighted. Using data from a choice experiment...

Transition risk - the financial stability risk related with decarbonization - is a major source of concern. The literature has so far only studied transition risk caused by carbon tax shocks. This paper explores other potential sources of transition risk: two other policy sources - subsidies to...

We survey various ethical issues related to the use of pollution pricing. While pollution pricing, for example in the form of Pigouvian taxes or cap-and-trade systems, is widely used in environmental economics modeling, many moral and ethical assumptions lie behind those models, and many ethical...

We study the distributional effects of a pollution tax in general equilibrium, with general forms of substitution where pollution might be a relative complement or substitute for labor or for capital in production. We find closed form solutions for pollution, output prices, and factor prices....

We estimate the causal effects of acute fine particulate matter (PM 2.5) exposure on mortality and health care use among the US elderly using Medicare administrative data and a novel instrument for air pollution: changes in the local wind direction. We then develop a new methodology that uses...

This article reviews and evaluates the nascent literature on the economics of climate engineering. The literature distinguishes between two broad types of climate engineering: solar radiation management and carbon dioxide removal. We review the science and engineering characteristics of these...

We study optimal climate policy when climate tipping points and solar geoengineering are present. Solar geoengineering reduces temperatures without reducing greenhouse gas emissions. Climate tipping points are irreversible and uncertain events that cause large damages. We analyze three different...

We consider the socially optimal use of solar geoengineering to manage climate change. Solar geoengineering can reduce damages from atmospheric greenhouse gas concentrations, potentially more cheaply than reducing emissions. If so, optimal policy includes less abatement than recommended by...
