| At the present time no widely accepted temporal emissions path for greenhouse gases has been developed and adopted at either a country or a global level. What does exist is a set of near-term, country-level emissions targets associated with the first commitment period of the Kyoto Protocol and a process for the determination of targets for subsequent commitment periods. However, the first commitment period targets specified by the protocol have been heavily criticized on the grounds that they are arbitrary and ad hoc. The purpose of this paper is to examine the conceptual foundations upon which one might base a domestic climate policy for the United States and to attempt to determine whether a near-term emissions target can indeed be derived from... |

| Iron deficiency is a widespread nutritional problem in developing countries, causing impaired physical activity and cognitive development, as well as maternal mortality. Although food fortification and supplementation programmes have been effective in some countries, their overall success remains limited. Biofortification, that is, breeding crops for higher micronutrient content, is a relatively new approach. We propose a methodology for ex-ante impact assessment of iron biofortification, which builds on disability-adjusted life years (DALYs) and a large household data set. Our analysis of iron-rich rice and wheat in India indicates sizeable potential health benefits. The cost-effectiveness of iron biofortification compares favourably with other... |

| The objective of this research was to estimate the effect of using bur extractors in cotton stripping on foreign material in harvested cotton, on both quality attributes and lint turnout, and to determine the minimum harvested acres a producer must have for a bur extractor to be cost effective. Results indicate that the bur extractor has significant effect in reducing bur percent, stick percent, and in increasing seed cotton percent and lint turnout, while is showed no statistically significant effect on any of the quality attributes. Results also suggest that investment in bur extractors is profitable for both irrigated and dryland cotton production situations with an operation of at least 750 acres. This study provides a simple method that can be... |

| Monetary contributions might not be appropriate welfare measures in contingent valuation (CV) when household incomes are very low. In such cases, willingness to pay (WTP) is restricted by a household's ability to reduce its consumption of other goods to pay for the environmental good under valuation. Beneficiaries, however, may be willing to contribute their time to work on a project instead of paying money. In this context, we assess the benefits of ecosystem services restoration in a rural area of high conservation value in central Chile, using a CV study that includes two WTP questions, one for cash and another for labor payments. The results indicate that labor payments in the form of a number of working hours per week were highly accepted among... |
