改造小农经济是转轨时期社会主义建设的最艰巨的任务之一。本从家庭经营、规模经营、农业产业化、农村剩余劳动力、农地制度创新等5个方面总结了理论界对小农经济改造的争议与研究,并认为改造小农经济应以邓小平“两个飞跃”理论作为理论基础。 相似文献

我国市场经济改革和经济发展的首要任务是农村的货币化和城市化,"三农问题"是当前我国经济结构中最重大的问题.在我国经济高速发展的同时,我国经济也存在着沦为"富人经济"的巨大风险.在这个问题上,提高农业劳动生产率和发展乡镇企业都不能从根本上解决问题,只有通过城市化、通过高速发展的经济来迅速转移农村剩余劳动力,实现农民市民化、农业工业化才能解决"三农"问题,才能使我国经济健康运行. 相似文献

基于世代交叠理论和劳动闲暇理论以及CFPS数据,从商业养老保险的投保情况与收入情况两个层面实证分析商业养老保险对土地流转的影响。结果显示:商业养老保险一方面通过提高家庭养老保障水平的方式影响家庭参与土地流转的意愿,另一方面通过增加转移收入的方式影响家庭土地流转规模。参保商业养老保险对于土地流转意愿的影响还存在地区差异。 相似文献

This paper addresses the question of how uncertainty in costs and benefits affects the difficulty of reaching a voluntary agreement among sovereign states. A measure of difficulty is constructed related to side-payments necessary to make an agreement a Pareto-improving move. Using a simple model, it is shown that uncertainty actually makes agreement easier.JEL classifications: Q5, H4, D7, D8An earlier version of this paper was presented at the Conference on Risk and Uncertainty in Environmental and Resource Economics, Wageningen, The Netherlands, June 2002. 相似文献

Is Meta-Analysis a Noah's Ark for Non-Market Valuation? 总被引:1,自引:0,他引:1
This paper describes meta-analytical methods as they have been appliedto non-market valuation research. These studies have
been used to reviewand synthesize literature and, more recently, in benefit transfer. Thissecond use imposes a higher standard
on the consistency in economicconcepts being summarized and in the resources included in ameta-analysis. To meet this need,
the paper proposes and illustrates astructural framework using a generalized method of moments estimator toestimate the parameters
of a preference function with the benefitsestimates usually encountered in meta-analytic summaries. 相似文献

Although oil spills from tanker accidents receive the most publicity, most vessel spills are not the result of accidents but of oil transfer activities. We investigate determinants of the size of vessel oil transfer spills as well as the effectiveness of Coast Guard enforcement activities in reducing their size. Vessel out-of-water and in-water oil transfer spillage functions are estimated utilizing tobit regression and detailed data on individual vessel oil transfer spills as well as Coast Guard safety/environmental enforcement activity data for the 1991–1995 period. Our estimation results suggest that Coast Guard hull but not machinery inspections are effective in reducing both out-of-water and in-water spills; patrols by air, but not by boat, are effective in reducing out-of-water spills; but neither is effective in reducing in-water spills. The results also show that the type of vessel (oil- and non-oil-cargo), vessel characteristics, vessel operations, weather/visibility conditions, and waterway type are determinants of post OPA-90 vessel oil transfer spills. 相似文献

Altruism is a type of non-use value which can have different definitions depending on the type of goods entering the utility function of the altruists and their expectations about the contributions of others. The purpose of this paper is to measure the trade-offs between different types of altruist values originating from social and environmental policies. Environmental policies are concerned with reducing health effects from a power plant while social policies involve both the attainment of public facilities for education and leisure and an increase in the income of the affected population. The empirical application utilizes a choice experiment technique which allows for valuation of multiple goods. Health effects are decomposed into the values of the risk of becoming ill, the duration of the episodes and the limitations imposed by illness. Altruist values are elicited from a population that is not affected by pollution. Results show that altruism is significant for policies directed to reducing health effects and improving the income level of the affected population, whereas there is egoism for a policy aimed at improving public facilities in the polluted suburb. The value of altruism is significantly influenced by the expectations of net benefits to be received by the affected population. 相似文献

Hedonic models and air pollution: Twenty-five years and counting 总被引:2,自引:1,他引:2
This paper reports a meta analysis of how effectively hedonic property models have detected the influence of air pollution on housing prices. Probit estimates are reported describing how data, model specification, and local property market conditions in cities represented in thirty-seven studies influence the ability of hedonic models to uncover negative, statistically significant relationships between housing prices and air pollution measures.Partial support for this research was provided by the Russell Sage Foundation. Thanks are due David Cordray, Heidi Hartman, and Larry Hedges of the Foundation's Meta-Analysis Panel for constructive comments, to Ray Palmquist for suggestions and assistance in assembling the results from his studies, to Rick Freeman and Tom Tietenberg and two anonymous referees for comments on the research, and to Barbara Scott for constructive editing of earlier drafts of this paper. 相似文献
