流动人口对县级政府基础教育支出影响研究--基于2009～2014年江苏省44个县市数据

本文使用了2009～2014年江苏省44个县市的数据①,利用面板数据进行回归分析,证明了地方教育财政支出会受到流动人口、地方经济发展等因素影响;人口流动会对人口流入地县市产生教育资源挤占效应,地方政府基础教育财政支出可能存在自利性动机,为了实现本地利益最大化,会对流动人口子女在本地入学设置相关门槛;这些发现表明,我们在发展地方经济、加大转移支付及实现义务教育经费随学籍走制度的同时,需要对产生问题的根源户籍制度进行改革,接纳农民工子女进入本地公立学校,才能实现中央“两为主”政策的教育公平目标。     

农村移民社会保险研究

文章分析了农村移民进行社会保险的必要性。从家庭生产理论出发论述了在确定征地社会保险时以家庭为单位来选择接受社会保险的对象是必须的。农村移民社会保险对象的确定是重要而且操作性很强的一项工作,以个案论述了保险对象确定的方法。提出了农村移民社会保险应关注的几个问题,特别强调政府应加强对农村移民社会保险基金的来源、安全和便利性管制。     

Sample Splitting and Applied Econometric Modeling

Often in applied econometric work, the sample of observations is split so that within each subsample the observations can reasonably be assumed to have the same parameter values. In this article I present a procedure for sample splitting that uses cluster analysis techniques. The procedure is illustrated with data from a cross-section of households obtaining subsamples with homogeneous demand parameters. The groups turn out to be determined, primarily, by occupation of the family head. Demand behavior is studied in each of the resulting groups.     

On Conditional and Partial Correlation

A graphical technique, similar in spirit to probability plotting, can be used to judge whether a Poisson model is appropriate for an observed frequency distribution. This “Poissonness plot” can equally be applied to truncated Poisson situations. It provides a type of robustness for detecting isolated discrepancies in otherwise well-behaved frequency distributions.
