农民增收的极限约束与跨跃路径

从长期看,农民增收有两个极限性约束条件:一是收入增长速度不能高于或者相当于城市居民收入增长速度;二是农民收入增幅不能高于农村财富的增幅。但是农民收入又不能不维持大幅度的增长,否则会影响国民经济的增长,影响政治社会的稳定。要解决这对矛盾,必须通过农村内部挖潜,拓宽内源性增收空间;调整束缚增收的制度;寻找和扩大外源性增收渠道。     

Bioenergy Crop Production in the United States: Potential Quantities, Land Use Changes, and Economic Impacts on the Agricultural Sector

The U.S. Departments of Agriculture and Energyjointly analyzed the economic potential for,and impacts of, large-scale bioenergy cropproduction in the United States. Anagricultural sector model (POLYSYS) wasmodified to include three potential bioenergycrops (switchgrass, hybrid poplar, and willow). At farmgate prices of US $2.44/GJ, anestimated 17 million hectares of bioenergycrops, annually yielding 171 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes highproductivity management practices are permittedon Conservation Reserve Program lands. Traditional crops prices are estimated toincrease 9 to 14 percent above baseline pricesand farm income increases annually by US $6.0billion above baseline.At farmgate prices of US $1.83/GJ, anestimated 7.9 million hectares of bioenergycrops, annually yielding 55 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes managementpractices intended to achieve highenvironmental benefits on Conservation ReserveProgram lands. Traditional crops prices areestimated to increase 4 to 9 percent abovebaseline prices and farm income increasesannually by US $2.8 billion above baseline.     

Testing equality of variances in the analysis of repeated measurements

The problem of comparing the precisions of two instruments using repeated measurements can be cast as an extension of the Pitman-Morgan problem of testing equality of variances of a bivariate normal distribution. Hawkins (1981) decomposes the hypothesis of equal variances in this model into two subhypotheses for which simple tests exist. For the overall hypothesis he proposes to combine the tests of the subhypotheses using Fisher's method and empirically compares the component tests and their combination with the likelihood ratio test. In this paper an attempt is made to resolve some discrepancies and puzzling conclusions in Hawkins's study and to propose simple modifications.
The new tests are compared to the tests discussed by Hawkins and to each other both in terms of the finite sample power (estimated by Monte Carlo simulation) and theoretically in terms of asymptotic relative efficiencies.     

收入差距、位置消费与社会稳定

适度、合理的收入差距,不仅是激励人们竞争,促进发展的重要务件,也是位置消费产生的基本条件;但过分悬殊的收入差距则不仅会影响人们的社会心理,不利于提高有效消费,而且可能产生畸形的位置消费行为,甚至会因此影响社会的稳定.在分析和研究目前收入分配问题时,应当从位置消费的新视角研究它们对社会稳定的影响.研究位置消费有利于我们从人们相互比较的满意度中观察改革的效果,权衡各项利弊得失,并及时地采取微调措施,尽可能地减少改革的摩擦和阻力.     

试论调控个人收入分配的财税政策选择

根据实际情况，我国政府调控个人收入分配，在财政政策方面，应加快完善社会保障制度，加大转移支付力度，缩小地区经济差距，加大扶贫投入的力度；在税收政策方面，应进一步完善个人所得税制度，适时开征遗产税与赠与税，加强特别消费税的作用，建立个人财产税制，适时开征社会保障税。     

论新形势下收入分配中"效率与公平"关系

“效率与公平”是收入分配中一对永恒的矛盾。应当根据不同时期经济社会发展的形势采取不同的指导方针,作者根据当今社会经济发展的新形势,提出了调整收入分配上的“效率优先”原则,改行效率与公平并重,实现效率与公平的统一。     

我国现阶段居民收入分配差距的现状、成因及治理对策研究

收入分配过大不仅背离了社会公平和正义,而且直接侵害了人民群众的切身利益.因此,解决收入差距过分扩大问题意义重大.解决的思路是：树立正确的公平分配观,完善制度建设,把＂公有制分享经济运行机制＂引入初次分配,加大再次分配的力度.     

我国城乡居民健康公平性研究

本文采用历史的、比较的分析方法,运用基尼系数、洛伦茨曲线等分析工具,分别从筹资公平、服务提供公平和健康公平三个方面对我国城乡居民健康公平问题进行了定性与定量分析,得出了新型农村合作医疗制度的开展显著降低了城乡卫生服务筹资的基尼系数等一系列结果.根据研究结果,对城乡健康公平性与二元社会结构,与政府干预、市场调节之间的关系作了分析,并对提高城乡健康公平性提出了相关政策建议.     

对收入差距问题的思考

目前，我国的收入差距尚在可控制范围之内，我们应根据收入差距的不同成因采取不同措施对其进行合理调节，但这种调节并不必然会带来收入差距缩小的结果，税收在当前也不是一种有效的调节手段。
