纳什均衡的内涵、问题和前景--读《纳什均衡论》

纳什均衡理论由于具有十分强的解决问题的能力,不仅成了现代理论经济学分析方法的基础,而且还对自然科学、社会科学的许多领域产生了影响.但纳什均衡理论不是完美无缺的,"象棋博弈"、"性别博弈"、"蜈蚣博弈"都对纳什均衡的有效性提出了质疑.这就要求纳什均衡理论有新的发展,这种发展既包括超越非合作博弈与合作博弈的传统分类,也包括对纳什均衡理论逻辑起点--经济人的超越和扬弃.     

农民市民化政策范式变迁与发展趋势——基于政策文本的分析

政策范式是决策主体的政策思维与政策风格的反映,是近年来公共政策研究中兴起的重要分析方法。以政策文本分析方法为基础,围绕政策问题、政策价值取向、政策工具与政策话语四个方面,对改革开放以来我国农民市民化政策范式变迁进行研究,发现农民市民化政策不仅在话语措辞层面发生了深刻变化,而且在政策问题认定、政策目标定位、政策工具选择层面也经历了渐进的变迁过程。总体而言,农民市民化政策范式渐趋包容性、公平性与人本性,不断彰显农民与市民共生进化的理念将成为市民化政策的重要特点与发展主流。

"上与造物者游,而下与外死生无终始者为友"--对庄子生死观的一个考察

本文在于从本体论的角度和高度("以道观之"),对先秦道家最为重要的代表人物庄子的生死观作一个较为深入也较为全面的考察,并在同西方最为重要的死亡哲学家海德格尔的对比研究中凸现庄子死亡思想的世界意义和现时代意义.     

国际人权公约与我国人权立法的比较

本文通过国际人权公约和我国人权立法的比较,可以看到我国人权立法与世界共同标准不断接近的轨迹.尽管权利的确立和保障,要受一国经济、社会和文化发展水平的制约,采取的步骤应与一国的国情和承受能力相适应.但毫无疑问,继续缩小两者的差异,解决相互间的冲突,是我国人权立法完善和前进的方向.     

A Comparative Study of Segregation Patterns in Belgium,Denmark, the Netherlands and Sweden: Neighbourhood Concentration and Representation of Non-European Migrants

In this paper, we use geo-coded, individual-level register data on four European countries to compute comparative measures of segregation that are independent of existing geographical sub-divisions. The focus is on non-European migrants, for whom aggregates of egocentric neighbourhoods (with different population counts) are used to assess small-scale, medium-scale, and large-scale segregation patterns. At the smallest scale level, corresponding to neighbourhoods with 200 persons, patterns of over- and under-representation are strikingly similar. At larger-scale levels, Belgium stands out as having relatively strong over- and under-representation. More than 55% of the Belgian population lives in large-scale neighbourhoods with moderate under- or over-representation of non-European migrants. In the other countries, the corresponding figures are between 30 and 40%. Possible explanations for the variation across countries are differences in housing policies and refugee placement policies. Sweden has the largest and Denmark the smallest non-European migrant population, in relative terms. Thus, in both migrant-dense and native-born-dense areas, Swedish neighbourhoods have a higher concentration and Denmark a lower concentration of non-European migrants than the other countries. For large-scale, migrant-dense neighbourhoods, however, levels of concentration are similar in Belgium, the Netherlands, and Sweden. Thus, to the extent that such concentrations contribute to spatial inequalities, these countries are facing similar policy challenges.     

Unpacking Within‐Household Gender Differences in Partners' Subjective Benefits From Household Income

The authors examine how contributions to household resources, indicated by employment status, influence satisfaction with household income (SWHI) for members of male/female couples. They take changes in SWHI, which may differ within couples, to indicate changes in perceived benefits from their common household income, benefits that can go beyond individual consumption. Using data from the British Household Panel Survey for 2,396 couples from 1996 to 2007, three gender effects are identified. First, men predominate in making the type of contribution that most positively influences SWHI, namely, full‐time employment. Second, the effect of contributions depends on the gender of the contributor, with men's employment being more influential than women's. Third, within couples, making the more influential contribution, as men tend to do, leads to relatively greater SWHI. The authors conclude that gender asymmetry in contributions made to household resources is one way in which gender inequalities invade and inhabit households.     

A powerful test for uniformity to detect highly peaked alternativedensities

A new class of statistical tests for uniformity based on sample ranges is proposed to detect a uniform density contaminated by a density with one or more high peaks. These kinds of alternatives occur quite frequently, especially in physics. It is shown that the proposed tests arc consistent and have high Pitman asymptotic relative efficiencies. Results of a Monte Carlo power study indicate that they, compared with other tests of uniformity, possess good power properties.A comparative study of various tests is also conducted using real data. An effcient algorithm for computing out test statistic and a table of percentage points are given, providing a practical guide for using the new test.     

On the one-sample location hypothesis for mixed bivariate data

We study a hypothesis testing problem involving the location model suggested by Olkin and Tate (1961). Specifically, we derive a likelihood ratio lest of the associated location hypothesis as an alternative to the conventional method of carrying out separate tests for each of the parameters. A small sample Monte Carlo comparison indicates the general superiority of the former in terms of statistical power. We also comment briefly on the properties of the test.     

AGE,TIME, VINTAGE,AND PRICE INDEXES: MEASURING THE DEPRECIATION PATTERN OF HOUSES

Age, time, and vintage are key determinants of house prices, yet they cannot be included together linearly or as dichotomous variables in hedonic regressions as construction time + age of house = sale time. We introduce a method where the estimates of the age, time, and vintage effects on prices are obtained in a flexible manner, without requiring us to specify a pre‐determined functional form for any of these variables. Applying our method to Dutch data, we find that the estimated depreciation pattern over the life of houses does not follow the functional forms typically specified for the age of houses in hedonic regressions.
