Welfare calculations in discrete choice settings: An exploratory analysis of error term correlation with finite populations

A difference in logsum terms (also known as inclusive values) is becoming a standard practice for anticipating the welfare impacts of transport policy when choice alternatives are discrete and behavior is (assumed to be) random-utility maximizing. However, this calculation is only an approximation when the population under study is finite. This paper examines the effect of error term correlations in such welfare analyses with finite samples, recognizing that individual preferences and unobserved attributes influencing choice are unlikely to change much, if at all, across scenarios or across alternatives. Such measures appear reasonably robust to deviations in assumptions of correlation. Nevertheless, we identify cases when the synthetic population samples need to be quite large for the average logsum to be realized. Another finding in these results is the substantial variation that emerges across synthetic populations, suggesting that policies that appear welfare-improving (when evaluated with average welfare formulations) may well be welfare-reducing (or vice versa) for a wide variety of actual, finite populations.     

Population distribution,effective area and economic growth

The usual measure for the factor land is the total area. But total area is a flawed measure because land is of unequal quality. To account for land quality, we use an alternative measure called effective area. Effective area is based on spatial population distribution which captures both natural conditions and human activity. Theoretically, effective area explains economic growth better than total area that biases the measure of total factor productivity (TFP) growth. Empirically on the basis of 40 years of panel data for the United States, an increase of 10% in effective area is associated with an economic growth of 5%, and the omission of effective area undervalues the growth of TFP by 8.1%.     

人口迁移承接与珠三角城市经济社会结构演变的耦合

通过梳理珠三角外来迁移人口的特征,发现长期以来,珠三角都是我国承接迁移人口最多的区域,并且增长速度快,就业结构高级化,空间分布比较集中.通过Granger检验发现,外来迁移人口与经济发展水平和产业结构先进性之间存在单向的Granger因果关系;通过耦合协调模型实证研究发现,外来迁移人口数量与珠三角多数城市经济结构之间存在很高的耦合协调关系,与少数城市城市化水平之间存在较高的耦合协调关系,与多数城市的社会结构之间耦合协调关系较弱.     

我国三峡库区移民家庭收入的微观影响因素

利用重庆市云阳县移民的调查数据,按移民类型和受教育程度对移民家庭收入进行统计分析。然后,按移民类型、受教育程度、年龄段进行分组,对影响移民家庭收入的微观因素进行回归估计。结果显示:移民家庭的经营土地对其家庭收入的贡献不大;劳动力对家庭收入的贡献最大;从年龄结构的角度看,31～45岁、46～60岁年龄段的劳动力对家庭收入的贡献最大;当劳动力的人均受教育年限达到大专水平时,家庭收入会随着劳动力文化水平的提高而增加;16～30岁年龄组中大专文化劳动力比例对家庭收入的贡献显著为正;31～45岁、46～60岁年龄组中初中文化劳动力比例对家庭收入的贡献显著为负;劳动力的非农业收入明显高于农业收入。最后提出:应鼓励移民从事非农业;鼓励青年和中年劳动力向工业和服务业发达的城市自愿流动;鼓励移民子女接受大专及以上教育;尽快健全城镇和农村移民的养老保险制度和最低生活保障制度。     

On certain inequalities by Steffensen

Abstract

Extract

In this note we are concerned with the inequalities published by Steffensen in this Journal under the title: ?On a generalization of certain inequalities by Tchebycheff and Jensen?. I will show how these inequalities are represented in one form by the integrals of Stieltjes. These integrals have the advantage of containing both sums and the integrals of Riemann. The proof of this generalized theorem is also more simple, which shows that this theorem appears only in this generalization in its most natural form.     

浅析新时期我国流动人口子女的道德教育——以福建泉州市为例

随着我国经济的高速发展,不同地区间流动人口规模逐年扩大.针对流动人口子女的教育,尤其是道德教育形势更为严峻.通过对当前我国流动人口子女道德教育现状的分析,同时以流动人口众多的福建泉州为例,以期能为我国流动人口子女的道德教育提供借鉴.     

人口老龄化、经济增长与养老保险——基于辽宁省的实证分析

利用1991年—2011年的有关经济数据,使用经济计量的方法对辽宁省养老保险支出与人均GDP、65岁及以上老人占比之间的关系进行数量分析,结果显示,辽宁省养老保险支出占GDP的比例低于合理的支出水平,人口老龄化对养老保险支出的影响大于人均GDP的增长对养老保险支出水平的影响,未来较长一段时间辽宁省将继续面临养老保险入不敷出的严峻形势,并在分析的基础上提出了相应的政策建议。     

流出地流动人口计划生育管理问题研究

对人口流出地进行计划生育年度考核的调查发现,频繁的人口流动给人口信息登记、核实带来了较大的困难;在应对大规模、跨地区的流动人口方面,流出地在计划生育管理方面存在许多困难。必须建立适合流动人口计划生育管理和服务的动态管理体制,运用科学、有效、人性化的管理手段,加强流出地与流入地政府间合作,以强化流动人口计划生育管理服务。
