Intergenerational Justice When Future Worlds are Uncertain

Llavador, Humberto; Roemer, John E.; Silvestre, Joaquim - Barcelona Graduate School of Economics (Barcelona GSE) - 2010

Let there be a positive (exogenous)probability that, at each date, the human species will disappear. We postulate an Ethical Observer (EO) who maximizes intertemporal welfare under this uncertainty, with expected-utility preferences. Various social welfare criteria entail alternative von...

North-South Convergence and the Allocation of CO2 Emissions

Llavador, Humberto; Roemer, John E.; Silvestre, Joaquim - Barcelona Graduate School of Economics (Barcelona GSE) - 2010

We postulate a two-region world, comprised of North (calibrated after the US) and South (calibrated after China). Our optimization results show the compatibility of the following three desiderata: (1) Global CO2 emissions follow a conservative path that leads to the stabilization of...

Intergenerational Justice when Future Worlds Are Uncertain

Llavador, Humberto; Roemer, John E.; Silvestre, Joaquim - Cowles Foundation for Research in Economics, Yale University - 2009

Suppose that there exists a positive (exogenous) probability that at each date of a possibly infinite future, the human species will disappear. We postulate an Ethical Observer (EO) who must solve an intertemporal welfare maximization problem under this kind of uncertainty, with preferences that...

The Ethics of Distribution in a Warming Planet

Roemer, John E. - Cowles Foundation for Research in Economics, Yale University - 2009

The discounted-utilitarian social welfare function (DU) is used by the great majority of researchers studying intergenerational resource allocation in the presence of climate change (e.g., W. Nordhaus, M. Weitzman, N. Stern, and P. Dasgupta). I present three justifications for using DU: (1) the...

Intergenerational Justice and Sustainability under the Leximin Ethic

Roemer, John E. - Cowles Foundation for Research in Economics, Yale University - 2005

We model an intergenerational society, with a representative agent at each date, who must deplete a renewable resource, from which he derives utility, to produce consumption goods. We adopt the intergenerational lexicographic minimum as the social welfare function. Initially, technological...

Should we sustain? And if so, sustain what? Consumption or the quality of life?

Llavador, Humberto; Roemer, John E.; Silvestre, Joaquim - Economics Department, University of California-Davis - 2012

Sustainability has been largely replaced by discounted utilitarianism in contemporary climate-change economics. Our … approach rejuvenates sustainability by expanding the conception of the quality of life, along the lines of the UN Human … substituting consumption for the quality of life. Our sustainability results carry over. As it should be expected, optimal …
