Expected utility, μ-σ preferences,and linear distribution classes: A further result

This article is an extension of Meyer and Sinn's results on the representation of arbitrary von Neumann-Morgenstern functions in - space when the probability distributions to be compared belong to a linear distribution class. It shows that, when absolute risk aversion decreases, stays constant, or increases not too fast, an increase in , given , increases the indifference curve slope: increased riskiness increases the required marginal compensation for risk when risk is measured by the standard deviation of wealth or income.I gratefully acknowledge useful comments by Wolfgang Buchholz, Kai Konrad, Jack Meyer, Hans Schneeweiß, Dominique Thon, and Bengt Arne Wickström.     

论民事行政诉讼违法行为调查权的构建

民事行政诉讼违法行为调查权是随着司法体制改革产生的一项新生事物.本文通过对民事行政诉讼违法行为调查权产生的现实基础和法律渊源的阐述,重点分析在现有的法制框架下,民事行政诉讼违法行为调查权如何坚持其性质、功能、目标等法律定位,把握权力行使的方向、重点、界限、范围,促进权力行使的成果转化,以减少和消除实践中存在的因对此项权力认识错位导致的工作盲动和权力功能异化,保障民事行政诉讼违法行为调查权充分、准确发挥应有功效.     

邓小平对外开放思想的历史定位

邓小平把对外开放作为我国的一项基本国策,是邓小平对外开放思想的历史定位.这一政策的定位是邓小平在汲取马克思列宁主义和毛泽东思想有关对外开放思想的精髓,立足世界经济发展的潮流,总结社会主义建设的经验的基础上的所得出的重要结论.邓小平对外开放思想对于推动我们今天的改革开放事业有很大裨益.     

Modified Wilcoxon–Mann–Whitney Test and Power Against Strong Null

The Wilcoxon–Mann–Whitney (WMW) test is a popular rank-based two-sample testing procedure for the strong null hypothesis that the two samples come from the same distribution. A modified WMW test, the Fligner–Policello (FP) test, has been proposed for comparing the medians of two populations. A fact that may be under-appreciated among some practitioners is that the FP test can also be used to test the strong null like the WMW. In this article, we compare the power of the WMW and FP tests for testing the strong null. Our results show that neither test is uniformly better than the other and that there can be substantial differences in power between the two choices. We propose a new, modified WMW test that combines the WMW and FP tests. Monte Carlo studies show that the combined test has good power compared to either the WMW and FP test. We provide a fast implementation of the proposed test in an open-source software. Supplementary materials for this article are available online.     

The Impact of Portfolio Location Uncertainty on Probabilistic Seismic Risk Analysis

Probabilistic seismic risk analysis is a well‐established method in the insurance industry for modeling portfolio losses from earthquake events. In this context, precise exposure locations are often unknown. However, so far, location uncertainty has not been in the focus of a large amount of research. In this article, we propose a novel framework for treatment of location uncertainty. As a case study, a large number of synthetic portfolios resembling typical real‐world cases were created. We investigate the effect of portfolio characteristics such as value distribution, portfolio size, or proportion of risk items with unknown coordinates on the variability of loss frequency estimations. The results indicate that due to loss aggregation effects and spatial hazard variability, location uncertainty in isolation and in conjunction with ground motion uncertainty can induce significant variability to probabilistic loss results, especially for portfolios with a small number of risks. After quantifying its effect, we conclude that location uncertainty should not be neglected when assessing probabilistic seismic risk, but should be treated stochastically and the resulting variability should be visualized and interpreted carefully.     

从自发到自为:经济区位变动中的南汇政区改革探索

历史时期南汇曾作为大浦东地区的主体部分 ,受浦东成陆过程和水系格局的制约 ,以及产业结构的转换 ,行政空间体系的构建过程的影响 ,逐步呈现出与经济空间结构相分离的基本特征。在未来大浦东建设规划中 ,南汇恰好处于“山”字形增长轴的交会处 ,其社会经济发展状况将直接影响浦东、上海乃至长江三角洲的未来前景。本文通过长时段的考察 ,揭示南汇地区政区演变的内在规律及不合理现状产生的根源 ,提出充分尊重历史规律、适应新经济区位的区划调整从自发到自为转变的基本思路。这一探讨对于当今经济格局变动中的基层政区改革 ,具有重要的理论意义和实践价值。     

资源禀赋、制度质量与外商直接投资——基于投资引力模型的实证分析

东道国的要素禀赋、制度质量及制度差异对FDI的流动将产生怎样的影响？通过研究发现：东道国的要素禀赋、制度质量、历史经历及加入相关组织对FDI流入具有重要影响,但在不同国家具有显著差异。在高、中收入组,FDI更多的受＂市场＂因素驱动,而在低收入组,FDI存有依赖＂政府庇护＂寻求发展的＂非典型化事实＂;与高收入组相比,FDI在中、低收入组具有更为明显的＂制度接近性＂特征。
