This paper examines self-enforcing contracts as a financial mechanism for reducing carbon emissions from deforestation and forest degradation when the opportunity cost of the land (i.e., landholder type) is private information and is imperfectly correlated over time (i.e., partially persistent types). Because self-enforcement limits the feasible incentives, the conservation levels are constrained by the surplus created. Regardless of the degree of persistence of such opportunity costs across contracting periods, a first-best self-enforcing contract can deliver “additional” carbon sequestration beyond the business as usual scenario only if the value of forest conservation is sufficiently high. Otherwise, self-enforcing contracts can induce some, suboptimal level of carbon sequestration. The degree of persistence of opportunity costs across periods does not affect the amount of total payments provided in the optimal menu of contracts, but greater persistence of opportunity cost types leads to contracts that feature more of the total payment as a bonus in contracts for landholders with a high opportunity cost for their land and more of the total payment as an upfront fixed payment for landholders with a low opportunity cost. 相似文献

We present a method for estimating the benefits of years of education for reducing dementia symptoms based on the cost savings that would accrue from continuing independent living rather than relying on formal or informal carers. Our method for estimating the benefits of education involves three steps: first taking a year of education and seeing how much this lowers dementia, second using this dementia reduction and estimating how much independent living is affected and third applying the change in caregiving costs associated with the independent living change. We apply our method for estimating education benefits to a National Alzheimer’s Coordinating Center sample of 17,239 participants at 32 US Alzheimer’s disease centres over the period September 2005 and May 2015. 相似文献

Abstract . To what extent can young adult children rely on their parents for financial support? This question will take on added importance if the commitments of the Social Security system put greater strain on the children of retirees. Despite the critical role that parents have in supporting their children, why they help some and not others remains unclear. Findings using two waves of data from the Health and Retirement Study that control for the needs of children and the resources of parents suggest that parents give more inter vivos financial assistance to their disadvantaged children rather than focusing on children most able to give financial help in return. Other measures of child well‐being besides income, including home ownership, education, parental status, and marital status, also suggest that parents help needier children more. Children who live nearby also receive more, a finding consistent with exchange motives or simply the ability of these children to more stridently demand support. Neither altruism nor exchange theories explain why stepchildren receive substantially less support than naturally born or adopted children. The diversity of effects suggests that giving is based on heterogeneous motives—parents may temper their altruism for children by the degree to which they feel responsible and by the stridency of some children in seeking support. Findings are robust upon allowing for unobserved differences across families by estimating fixed effect models. 相似文献

In light of widespread concerns about the reliability of self‐reported disability, we investigate what can be learned about the prevalence of work disability under various assumptions on the reporting error process. Developing a nonparametric bounding framework, we provide tight inferences under our strongest assumptions but then find that identification deteriorates rapidly as the assumptions are relaxed. For example, we find that inferences are highly sensitive to how one models potential inconsistencies between subjective self‐assessments of work limitation and more objective measures of functional limitation. These two indicators appear to measure markedly different aspects of health status. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

The world sugar market has long been characterized by volatileprices and widespread intervention. Controls on domestic prices,demand, and supply have created an inefficient pattern of worldproduction, consumption, and trade. Without government controls,production would shift from the countries with higher cost,subsidized production (especially the European Community, Japan,and the United States) to the countries with lower costs (suchas Australia, Brazil, and Thailand). The resources saved couldthen be directed to other activities. Sugar policies in countries with high costs reduce world sugarprices quite substantially in the long run and increase pricevariability significantly; production controls in countrieswith low costs increase world prices somewhat and also increasetheir variability. What would happen if all interventions ceased? Average worldsugar prices would probably but not definitelyrise. World prices would definitely vary less, and economicconditions would definitely improve, especially in developingcountries that depend heavily on sugar exports. But the prospectsfor substantial reform of the sugar market are not promising,even though the GATT Uruguay Round continues. This article putsforward some modest proposals for changing the existing interventionsto lessen economic distortions and reduce costs. 相似文献

In a cross‐cultural tourist behavioral study, skiers from three different countries were surveyed in order to understand their environmental awareness and knowledge. The contingent valuation method (CVM) was also used to discover their willingness‐to‐pay (WTP) for environmentally‐friendly skiing products. The results point to a general lack of knowledge and even confusion amongst skiers about environmental issues pertaining to skiing. However, skiers say they will be more likely to visit a resort that is environmentally‐responsible. Use of the CVM indicated a strong correlation between WTP and the cost of the holiday, level of income and level of environmental conscience. The majority of skiers would pay more for a “greener” ski resort, but significant differences in responses were found between the three cultures. Theoretical and practical implications are discussed. 相似文献

This investigation considers the participation of children, adolescents and young adults in nature-based recreation. We draw upon the recreation narratives of forty-seven adult recreationists in the activities of tramping, angling, hunting and mountaineering, obtained from in-depth interviews. In particular, the study considers the transitions from childhood through adolescence to young adulthood, and examines how our participants maintained their participation, or alternatively, disengaged from their activity over this period. The paper provides empirical support for the role of family, and early exposure to nature based recreation in fostering enduring participation. Failing this, the role of school, club and outdoor organizational support and mentoring, right through to tertiary study was highlighted. We also identify a critical role for unstructured outdoor play for young children in nature. The paper discusses challenges for this, and for mentoring, in both formal and informal senses, as pathways into nature-based recreation in an increasingly risk averse society. 相似文献

Accurate demand forecasts are critical to maintaining customer service levels and minimizing total costs, yet increasingly difficult to achieve. Using weekly point‐of‐sale (POS) and order data for 10 ready‐to‐eat cereal stock‐keeping units from 18 regional U.S. grocery distribution centers, this research empirically investigates two demand forecasting issues: (1) the accuracy of top‐down versus bottom‐up demand forecasts; and (2) whether shared POS data improve demand forecast accuracy. The results reveal a previously unexplored relationship between demand forecast methodology and the use of shared POS data. We find that the superiority of the top‐down or bottom‐up forecasting as the more accurate demand forecast method depends on whether shared POS data are used. 相似文献
