Consistent Tests for Stochastic Dominance

Methods are proposed for testing stochastic dominance of any pre–specified order, with primary interest in the distributions of income. We consider consistent tests, that are similar to Kolmogorov–Smirnov tests, of the complete set of restrictions that relate to the various forms of stochastic dominance. For such tests, in the case of tests for stochastic dominance beyond first order, we propose and justify a variety of approaches to inference based on simulation and the bootstrap. We compare these approaches to one another and to alternative approaches based on multiple comparisons in the context of a Monte Carlo experiment and an empirical example.     

The Theory of Global Games on Test: Experimental Analysis of Coordination Games with Public and Private Information

The theory of global games has shown that coordination games with multiple equilibria may have a unique equilibrium if certain parameters of the payoff function are private information instead of common knowledge. We report the results of an experiment designed to test the predictions of this theory. Comparing sessions with common and private information, we observe only small differences in behavior. For common information, subjects coordinate on threshold strategies that deviate from the global game solution towards the payoff‐dominant equilibrium. For private information, thresholds are closer to the global game solution than for common information. Variations in the payoff function affect behavior as predicted by comparative statics of the global game solution. Predictability of coordination points is about the same for both information conditions.     

Mapping IS failure factors on PRINCE2® stages: an application of Interpretive Ranking Process (IRP)

The social, political and cultural issues faced by organisations and their senior management team in the delivery and adoption of strategic projects, is highly complex and problematic. Despite a mature body of literature, increasing levels of practitioner certification, application of standards and numerous government initiatives, improvements in success have been minimal. In this study, we analyse the key underlying factors surrounding the failure of Information Systems (IS) projects and explore the merits of articulating a narrative that focuses on senior management embracing practical pessimism. Specifically, we develop a hypothesis supported by empirical study that leverages expert’s views on the dominance and interrelationships between failure factors within PRINCE2® project stages using an Interpretive Ranking Process. Our findings establish how the concept of dominance between individual failure factors can necessitate senior management to make key informed and timely decisions that could potentially influence project outcomes based on an empirical derived, interpretive predictive framework.     

对幼儿园师幼互动若干问题的思考

在幼儿园中,师幼互动是贯穿于幼儿一日生活中最核心的人际互动,它构成了幼儿园教育的重要组成部分.师幼互动对幼儿发展的价值何在,如何正确认识师幼互动中公平与差异的关系以及互动双方在互动过程中的角色定位,如何创设积极有效的师幼互动的基本条件,是值得探讨的课题.     

More on the measurement of inequality

The article, written in 1973, examines what comparisons of income distributions can be made when Lorenz curves cross, employing the concept of third-order stochastic dominance. “More on the measurement of inequality” as reviewed by Prof. P. Lambert will appear in the Rediscovered Classics section, along with the editorial.     

迭代法迭代阵谱半径新上界

引用双严格对角占优的概念,针对线性方程组bAx=在求数值解时常用的迭代方法,给出了Jacobi和Gauss-Seidel迭代法迭代阵谱半径的新上界,该新上界优于严格对角占优矩阵条件下得到的已有的结果,是已有结果在更广泛矩阵类条件下的推广,对相应迭代法迭代阵谱半径的估计更加精确。最后给出了数值例子说明所给结果的优越性。     

美国意识形态多元维度分析--国际政治学意义测度和梳理

从国际政治学意义测度,美国意识形态体现为多元维度以美国为主导的历史使命观、以"自由与民主"为核心的政治价值观、以"敌视共产主义"为主要目的的政治制度思想,并在国家利益的旗帜下相互作用,构成了整个政治意识形态的基本链条.美国历史外交传统和现代外交风格的选择和确立均与其意识形态的独特性存在内在的政治逻辑关系.     

社会状态估计的随机优势方法及可分解方法

近年发展起来的对社会状态进行比较的随机优势方法,以及研究状态决定的可分解方法及多因素回归分析方法,为我们提供了充足的实用工具来对社会状态进行评估,可为决策制定者充分掌握决策对象的经济发展水平及福利水平,以选择正确的发展道路和效率目标提供决策依据。尽管对社会状态估计方法的研究仍然存在相当多的困难,但近年来在这方面已经取得的成果表明未来的道路是光明的。     

Prospect theory for continuous distributions

We extend the original form of prospect theory by Kahneman and Tversky from finite lotteries to arbitrary probability distributions, using an approximation method based on weak-⋆ convergence. The resulting formula is computationally easier than the corresponding formula for cumulative prospect theory and makes it possible to use prospect theory in future applications in economics and finance. Moreover, we suggest a method how to incorporate a crucial step of the “editing phase” into prospect theory and to remove in this way the discontinuity of the original model.
