Long-Term Environmental Problems And Strategic Intergenerational Transfers, Timo Goeschl, Daniel Heyen, Juan B. Moreno-Cruz
Long-Term Environmental Problems And Strategic Intergenerational Transfers, Timo Goeschl, Daniel Heyen, Juan B. Moreno-Cruz

The impacts of long-lived stock pollutants and the measures supposed to address them link current and future generations. Altruism towards successor generations is a prerequisite for resolving the resulting inter-generational equity issues. Preference asymmetry and imperfect altruism introduce strategic conflicts between generations. Here, a current generation decides on a combination of abatement and whether to provide an imperfect backstop. The future generation decides whether to use the backstop or not. We identify three outcomes: (1) Technology denial, in which the current generation deliberately rejects the imperfect backstop to avoid misuse by the future generation. (2) Under-abatement, in which the current …

The purpose of this paper is to introduce the concept of power density [Watts/m2] into economics. By introducing an explicit spatial structure into a simple general equilibrium model we are able to show how the power density of available energy resources determines the extent of energy exploitation, the density of urban agglomerations, and the peak level of income per capita. Using a simple Malthusian model to sort population across geographic space we demonstrate how the density of available energy supplies creates density in energy demands by agglomerating economic activity. We label this result the density-creates-density hypothesis and evaluate it using …
A Simple Model To Account For Regional Inequalities In The Effectiveness Of Solar Radiation Management, Juan B. Moreno-Cruz, Katharine L. Ricke, David W. Keith
A Simple Model To Account For Regional Inequalities In The Effectiveness Of Solar Radiation Management, Juan B. Moreno-Cruz, Katharine L. Ricke, David W. Keith

We develop a simple measure of the potential effectiveness of solar radiation management (SRM) in compensating for anthropogenic climate change and test this measure using data from an ensemble of modeling experiments conducted with a general circulation model (GCM). Assuming a linear relationship between the amounts of SRM implemented globally and the regional temperature and precipitation responses to that change, we calculate the amount of SRM that minimizes impacts using three different social objectives: egalitarian, utilitarian and ecocentric. While inequalities in the effectiveness of SRM between regions are important, they may not be as severe as is often assumed. When …
Climate Policy Under Uncertainty: A Case For Solar Geoengineering, Juan B. Moreno-Cruz, David W. Keith
Climate Policy Under Uncertainty: A Case For Solar Geoengineering, Juan B. Moreno-Cruz, David W. Keith
Juan B. Moreno-Cruz
It appears to be technically feasible to engineer an increase in albedo, a planetary brightening, as a means to offset the warming caused by carbon dioxide (CO2) and other greenhouse gases through Solar Radiation Management (SRM). This option has two characteristics that make it attractive for managing climate risk: it is quick and cheap. However, SRM cannot exactly compensate for the CO2-driven climate change. Moreover, SRM introduces risks in the climate system that are unique to this type of intervention.We introduce SRM in a model of climate change economics and analyze the optimal policy under uncertainty. We find that the …
Revisiting The Economics Of Climate Change: The Role Of Geoengineering, Juan B. Moreno-Cruz, Sjak Smulders
Revisiting The Economics Of Climate Change: The Role Of Geoengineering, Juan B. Moreno-Cruz, Sjak Smulders
Juan B. Moreno-Cruz
Technically simple and reversible measures to directly reduce mean global temper- atures could be available anytime soon. We introduce the concept of \geoengineering" into an analytical model of climate change. We model the technical and economic characteristics of geoengineering in line with the recent literature from physical and environmental management sciences. We investigate (i) under which circumstances geoengineering can substitute, partly or completely, for traditional abatement strate- gies, (ii) under which conditions and at what level geoengineering is optimally em- ployed, and (iii) whether geoengineering can mitigate free-riding problems.
