I derive alternative measures of maximum willingness to pay (WTP) and value of statistical life (VSL) related to changes in the supply of a public good affecting mortality for both members of two-person households, when members are selfish, live for at most two periods, and strike efficient Nash...

I derive the value of marginal changes in a public good for two-person households, measured alternatively by household member i’s willingness to pay (WTP) for the good on behalf of the household, WTPi(H), or by the sum of individual WTP values across family members, WTP(C). Households are...

The paper discusses how to derive empirical estimates of the value of a statistical life (VSL) from observations of highway driving speeds, and from how such speeds are affected by speed limits and penalties for speeding. When drivers optimize with respect to driving speeds, we discuss three...

This paper discusses possible macroeconomic implications for low-income countries of increased revenue inflows that may follow from implementing certain global greenhouse gas mitigation policies. Such revenue sources include revenue from emissions offset mechanisms, direct investments, and...

This paper discusses short-run and long-run effects of "green stimulus" efforts, and compares these effects with "non-green" fiscal stimuli. Green stimulus is defined here as short-run fiscal stimuli that also serve a "green" or environmental purpose in a situation of "crisis" characterized by...

This paper develops a global model of climate policy, focusing on the choice between tax and cap-and-trade solutions. The analysis assumes that the world can be split into two regions, with two fuels that both lead to carbon emissions. Region A consumes all fuels, and is responsible for defining...

This paper uses some simple conceptual models to draw out various implications of infrastructure investments with long lifetimes for the ability of societies to reduce their future greenhouse gas emissions. A broad range of such investments, related both to energy supply and demand systems, may...

Interests in obtaining carbon offsets in host countries for Clean Development Mechanism projects may serve as an obstacle to implementing more stringent general environmental policies in the same countries. A relatively lax environmental policy, whereby carbon emissions remain high, can be...

When a groundwater basin is exploited by a large number of farmers, acting independently, each farmer has little incentive to practice conservation that would primarily benefit other farmers. This can lead to excessive groundwater extraction. When farmers pay less than the full cost of...

Investments in large, long-lived, energy-intensive infrastructure investments using fossil fuels increase longer-term energy use and greenhouse gas emissions, unless the plant is shut down early or undergoes costly retrofit later. These investments will depend on expectations of retrofit costs...
