within a population, the sizes of eggs and clutches vary, and the combination of both determines a female’s reproductive investment. we investigated females’ investment in clutches of the Chilean Swallow (Tachycineta meyeni) at the southern limit of its range, where it breeds in an extreme climate. we analyzed variation in clutch, egg and yolk size in relation to the female’s condition, date of...

Climate policy regarding perfluorocarbons (PFCs) may have a significant influence on investment decisions in the production of primary aluminum. This work demonstrates an integrated analysis of the effectiveness and likely economic consequences of different climate policy options. In our study we first compare atmospheric observations to the available estimates of PFC emissions for the baseline...

Global climate change presents a classic problem of decision making under uncertainty with learning. We provide stochastic dominance theorems that provide new insights into when abatement and investment into low carbon technology should increase in risk. We show that R&D into lowcarbon technologies and near-term abatement are in some sense opposites in terms of risk. Abatement provides insuranc...

Both climate change and technical change are uncertain. In this paper we show the importance of including both uncertainties when modeling for policy analysis. We then develop an approach for incorporating uncertainty of technical change into climate change policy analysis. We define and demonstrate a protocol for bottom-up expert assessments about prospects for technologies. We then describe a...

Ethical investments are a now a considerable sector in the investment market, with the Financial Times running the headline “Green and ethical investment comes of age” (Shepherd, [1]). Claudia Quiroz (lead fund manager for Cheviot Climate Assets Fund) predicts a strong future for ethical investment, with sustainable investment becoming a growing theme (Hoskin [2]). Much previous research in the...

Ethiopia is at a critical crossroads with a burgeoning population, a severely depressed national economy, insufficient agricultural production, and a minimal number of developed energy sources. This study assesses how investment in and management of water resources, together with related policy reforms, may mitigate the negative effects of hydrologic variability on the performance and structure...
