This paper focuses on two equity dimensions of climate policy, intra- and intergenerational, and analyzes the implications of equity preferences on climate policy, and on the production and consumption patterns in rich and poor countries. We develop a dynamic two-region model, in which each...

We provide counterexamples to the idea that mitigation of greenhouse gas emissions, and adaptation to climate change, are always substitutes. We consider optimal mitigation policy when climate damages follow a geometric Brownian motion process with positive drift and mitigation is lumpy. Climate...

The economic effects of climate change on agriculture have been widely assessed in the last two decades. Many of these assessments are based on the integration of biophysical and agro-economic models, allowing to understand the physical and socio-economic responses of the agricultural sector to...

Recent studies have drawn attention to the high prevalence of stunting among children in rural India. In fact, these estimates point to more pervasive deprivation than conventional measures of poverty based on income or consumption expenditure shortfalls imply. Since stunting reflects cumulative...

What are the ethical implications of our contributions to global warming on an individual level? In his extended essay, John Broome analyzes the moral implications of our imposing damages on future generations through our greenhouse-gas emissions. He argues that we as individuals owe restitution...

Nearly all discussions about the appropriate consumption discount rate for climate-change policy evaluation assume that a single discount rate concept applies. We argue that two distinct concepts and associated rates apply. We distinguish a social-welfare-equivalent discount rate appropriate for...

Climate science indicates that climate stabilization requires low GHG emissions. Is this consistent with nondecreasing human welfare?

Emission inequality across countries and the contribution of the energy mix and the sectoral composition of a country's energy use are of central importance to the climate debate. We analyze the evolution of inequality in global CO2 per-capita emissions using both historical data on...

We discuss self-interested uses of equity arguments in international climate negotiations. Using unique data from a world-wide survey of agents involved in international climate policy, we show that the perceived support of different equity rules by countries or groups of countries may be...
