Managing and financing metropolitan public services in China: experience of the Pearl River Delta region

Under China’s current fiscal policies and inter-governmental relations, it is a significant challenge to finance and deliver public services across jurisdictions. This challenge was met in the Pearl River Delta region in southern China with a collaborative governance approach. Directives from higher-level governments and horizontal inter-city fiscal arrangements were successfully combined to deliver public services. Effective networks should be developed to improve co-ordination and collaboration in delivering cross-jurisdictional public services.

中国省区工业产业专业化程度实证研究:1988～2002

本文通过构造产业地方专业化基尼系数,利用工业产业增加值数据,直接测算从1988年到2002年每个省区的工业产业专业化水平,发现我国省区产业结构出现了“两头高,中间低”的格局。根据各个省区十几年的地方专业化基尼系数的整体变化趋势,把省区划分为降低型、U型、增高型和大致不变型,并发现中西部的专业化程度提高,而东部大部分省区的产业结构经历了一个调整的过程,地方专业化基尼系数先降低,之后有些发达省份又有所提高。     

从三因素模型看行为金融学

法玛和法兰奇三因素模型 1953,马科维兹(Markowitz)在一定的经济模型假设下得出了均值一方差的有效市场模型,并初步建立了CAPM的基础;后来,Sharpe(1964年)、Lintner(1965年)和Black(1972年)引入了表征每种证券风险的β值,并提出了著名的CAPM模型.在CAPM模型中,股票的收益率水平用其收益率的期望表示,而其风险则用β值表示.     

百年农民观念变与不变的经济学分析

近百年以来,或因政权变更、或因现代化建设,农村土地资源的占有使用支配等发生变化,附着在其上的观念也发生变化：被剥夺意识强化、宿命等传统意识逐渐淡化和稀释、阶级意识填补了传统意识稀释而留下的空间、工业观念深入人心、传统小农意识之壳中不断增添新内容。而有些制度则没有改变或虽改变却承载的意识不变,附着其上的观念则变化不大：宗族意识、均平意识、宿命意识、循环意识、贵土贱农意识等仍然存在。农民观念的现代化,最重要的是农民生活于其中的经济制度的现代化。不触动农民生活于其中的经济制度,被思想运动清除掉而成为历史的东西将会卷土重来。

Non-parametric method for European option bounds

There is much research whose efforts have been devoted to discovering the distributional defects in the Black–Scholes model, which are known to cause severe biases. However, with a free specification for the distribution, one can only find upper and lower bounds for option prices. In this paper, we derive a new non-parametric lower bound and provide an alternative interpretation of Ritchken’s (J Finance 40:1219–1233, 1985) upper bound to the price of the European option. In a series of numerical examples, our new lower bound is substantially tighter than previous lower bounds. This is prevalent especially for out of the money options where the previous lower bounds perform badly. Moreover, we present how our bounds can be derived from histograms which are completely non-parametric in an empirical study. We discover violations in our lower bound and show that those violations present arbitrage profits. In particular, our empirical results show that out of the money calls are substantially overpriced (violate the lower bound).

Better peers,better scores? A study of twin junior high school graduates in Taiwan

Using data of twin students graduating from junior high schools between 2002 and 2004 in Taiwan, we estimate the effects of peers on high school joint entrance examination performance. To alleviate the potential endogeneity of peer educational achievement, linear models with twin fixed effect and instrumental variables are estimated. Quantile, quantile with twin fixed effect and quantile with instrument variables regressions are also implemented to determine whether estimated peer effects differ at various locations of the testing scores’ conditional distributions. Positive and statistically significant peer effects are found to exist at the mean and at different quantile levels.
