The common practice consists in using a unique value of the discount rate for all public investments. Endorsing a social welfare approach to discounting, we show how different public investments should be discounted depending on: the risk on the return of the investment, the systematic risk on...

We study how the distribution of income among members of society, and income inequality in particular, affects social willingness to pay (WTP) for environmental public goods. We find that social WTP for environmental goods increases with mean income, and decreases (increases) with income...

We study how income inequality affects the social value of a dynamic public good, such as natural capital. Our theory shows that both intra- and intertemporal inequality affect the social value of public natural capital. The direction and size of the effects are driven by the degree of...

This paper presents a novel way to disentangle inequality aversion over time from inequality aversion between regions in the computation of the Social Cost of Carbon. Our approach nests a standard efficiency based Social Cost of Carbon estimate and an equity weighted Social Cost of Carbon...

How income and the valuation of environmental goods are related is a key question for science and policy, but the role of income inequality is often neglected. This paper studies how income inequality impacts the international transfer of environmental values-a practice called value or benefit...

How the valuation of environmental goods is related to income is a key question for environmental economics, but the role of income inequality is often neglected. We study how income inequality affects the international transfer of the valuation of environmental goods - a practice called value...

Specialized theoretical and empirical research should in principle be embedded in a unified framework that identifies the relevant interactions among different phenomena, enables an appropriate matching of policy instruments to objectives, and grounds normative analysis in individuals' utilities...
