Resolving Rabin’s paradox

We present a theoretical model of Rabin’s famous calibration paradox that resolves confusions in the literature and that makes it possible to identify the causes of the paradox. Using suitable experimental stimuli, we show that the paradox truly violates expected utility and that it is caused by reference dependence. Rabin already showed that utility curvature alone cannot explain his paradox. We, more strongly, do not find any contribution of utility curvature to the explanation of the paradox. We find no contribution of probability weighting either. We conclude that Rabin’s paradox underscores the importance of reference dependence.

     

Level of choice in older women’s decisions to retire or continue working and associated well-being

Retirement is a complex life transition. Women’s retirement, like their work lives, may be further complicated, for example, by family or financial obligations; they may feel forced to retire or to continue working or feel they have the choice to do so. This study examines the role of voluntary versus involuntary retirement or continued work participation among retirement-age women; specifically, the relationships between choice, work status, and well-being. Compared to women forced to retire, women who chose retirement or continuing to work had higher levels of life satisfaction. Findings highlight the importance of examining retirement within the life course context.     

土地混合使用视角下的城市工业地块更新改造路径——以上海金沙江路地块为例

城市工业用地的更新改造是城市调整产业结构、建设创新社会的一个新常态的问题。在全球化大背景下,随着产业结构的调整升级,产业的类型直接影响到工业用地的布局形式,"退二进三"作为工业地块更新改造的主要方式,已经被广泛接受并执行。在城市更新的过程中,工业地块的更新是促进城市产业转型、优化城市功能的重要一环,对城市工业地块更新改造的路径探讨具有非常重要的现实意义。在对上海工业地块的更新改造政策措施与实施情况综合评述的基础上,以上海金沙江路地块为例,找出城市工业地块更新改造的现状问题与路径局限,并围绕更新改造路径的多种可能进行深入探讨。笔者建议科学评判,综合调整地块更新改造路径,从区域的角度统筹考虑功能业态,以保障城市工业地块的更新改造受益面广,更具有综合协调性。

Data‐Driven Supply Chain Orientation and Financial Performance: The Moderating Effect of Innovation‐Focused Complementary Assets

Drawing on the complementary assets framework, this study explores the moderating effect of innovation‐focused complementary assets (CA‐I) on the relationship between a data‐driven supply chain orientation (DDSCO) and firm financial performance. To test the moderating effect, survey data gathered from 329 manufacturing firms in China were analysed using a moderated regression analysis. The results indicate that DDSCO has a significant positive effect on financial performance, and that capabilities for product and process innovation function as complementary assets moderating the DDSCO–performance relationship. The findings suggest that innovation‐focused complementary assets are performance differentiators when paired with a DDSCO and explain why some firms obtain financial benefits from the development of a DDSCO while others do not. Specifically, competitive advantage from a DDSCO may not be realized unless CA‐I and potentially other complementary assets are harnessed, thus providing useful practical guidance to managers. Hence, the study provides empirical support for the complementary assets framework.     

A DECISION THEORY EXAMPLE IN FOOTBALL

In the 1967 Harvard-Cornell football game, Harvard was ahead 14–0 late in the game when Cornell scored two touchdowns. On both occasions, Cornell tried and failed on the two-point conversion attempt and lost the game 14–12. Postgame arguments were divided on the merits of Cornell's strategy. For this frequently occurring scenario in college football, we derive a maximum expected utility decision rule for the decision of kicking versus running/passing based on the relative utility of a win, a tie, or a loss and the probabilities of success with a kick as opposed to a run/pass.     

哥特的"演绎"

起源于欧洲中世纪教堂建筑中的哥特艺术,是以建筑实体形式凝固下来的一种文化存在。由于不同时期社会思想的影响和建筑技术的推动,哥特艺术总以不同的姿态和气质出现在各类建筑中。逐渐地,人们对它的情感体验超脱了建筑特定空间。当充满黑暗、恐怖、神秘色彩的哥特小说问世后,哥特艺术开始在音乐、电影等大众流行文化中蔓延。它所包含的内容和意义也在与社会意识和风尚的结合中不断地拓展和延伸。

鞍山是一座“温暖的城市”

钟绍坚,一个地地道道的台湾人,热情、风趣、幽默,说话慢条斯理,2008年从台湾来到鞍山,任中橡(鞍山)化学工业有限公司厂长。人们总是顺口称呼他为"钟总",他却谦虚地解释,只有统筹整个公司的人才叫"总经理",而中橡(鞍山)化学工业有限公司隶属于台湾水泥集团中橡化学工业有限公司,像他这样的职务他们习惯称之为"厂长"。说起来到鞍山的日子,钟绍坚至今准确地记得——2008年11月16日。说到对鞍山的第一感觉,钟绍坚笑着说":这里的人脾气很好,生活消费能力很高,这里商场的东西可不便
