论经济主体的道德重塑

"经济人"假设与经济主体的主体道德有限理性相左,使得经济社会出现诸多问题.修正的途径有:一是发挥政府主导作用;二是重建社会信用保障体系;三是建立完善的法律体系;四是加强诚信教育.     

科技理性、价值理性和人文关怀

改革开放以来,我国社会结构的变化与科技理性的张扬有密切关系。必须指出,科技理性只是理性的一个方面,它需要人文价值理性的判断、比较和匡正,人类道德的实践品格必须来自于价值理性的孵化。人文关怀所蕴涵着的巨大的精神力量实质上是要求关注每个人的生命意义和内心生活。在不断重视和强化人文关怀的基础上,一切表面上看来非常诱人的"说教"就会因失去生存和传播的温床而自行消亡。只有这样,人类才有可能在创造出高度物质文明的同时,创造出持久美好的人性流露和充溢的善感。     

国家对个人所有文化财产出口控制的法律分析

一国政府对个人所有的文化财产实施出1：7控制需要综合考虑合理性、合法性和可行性之间的关系。合法性涉及一国实施出口控制的权限和相应后果。可行性涉及一国的出口控制法律能否被他国所承认和执行。中国的文化财产出口控制法律体制具有明显的国家主义与民族主义特征，其域外效力有限，为提升该法律制度在国际层面的合法性和可行性，应重新审视该制度的合理性。     

Investing back homeReturn migration and business ownership in Albania1

This study uses data from the 2005 Albania Living Standards Measurement Study survey to assess the impact of past migration experience of Albanian households on non‐farm business ownership through instrumental variables regression techniques. Considering the differences in earning potentials and opportunities for skill acquisition in different destination countries, we differentiate the impact of past household migration experience by main migrant destinations. The study also explores the heterogeneity of impact based on the timing of migration. The empirical results indicate that past household migration experience exerts a positive impact on the probability of owning a non‐farm business. While one additional year in Greece increases the probability of household business ownership by roughly 6 percent, a similar experience in Italy or farther destinations raises the probability by over 25 percent. Although past household migration experience for the period of 1990–2000 is positively associated with the likelihood of owning a household enterprise, a similar association does not exist for the period of 2001–2004.     

有限理性假设下供应链合作博弈的定性模拟研究

本文放宽一般博弈论中理性人的假设,运用混合建模方法构建了有限理性下的供应链合作博弈模型,模型将供应链企业的收益模糊化并扩展供应链合作博弈中局中人的策略空间,可以选择从“0”(完全不合作)到“1”(完全合作)连续区间内的任何合作程度,策略集是连续的区间.模拟结果表现为供应链合作策略的调整过程,能够提供更有效的决策支持.在此基础上,以二人合作博弈为例,用结合定性信息的定性模拟方法对博弈过程进行研究,得到结论:在供应链合作中,无论是平均分配还是按成员企业的资源投入分配,从模拟结果来看,定性模拟方法的使用,对一些不具备完备信息,无法建立精确数学模型的博弈过程也可以进行分析,并得出相对满意的结论.     

COMPLEXITY AND RANDOMNESS IN MATHEMATICS: PHILOSOPHICAL REFLECTIONS ON THE RELEVANCE FOR ECONOMIC MODELLING

Abstract Mathematics itself is a complex system. It exemplifies complexity at the level of structure, hierarchy and so on. There is also an interesting notion of complexity present in the meaning of mathematical ‘alphabets’. These are unique writing strategies of mathematics. Yet another marker of complexity lies in the process of applying mathematics to models. Using mathematics in modelling is a process of deciding what kinds of models to construct and what types of mathematics to use. Modelling can be seen as a decision‐making process where the scientists are the agents. However in choosing mathematical structures the scientist is not being optimally rational. In fact, fertile uses of mathematics in the sciences show a complicated use of mathematics that cannot be reduced to a method or to rational principles. This paper argues that the discourse of satisficing and bounded rationality well describes the process of choice and decision inherent in modelling.     

Volatility in Cereal Prices: Intra‐ Versus Inter‐annual Volatility

Intra‐annual (within crop year) price volatility and inter‐annual (between crop years) price volatility are measured for wheat, maize, rice, barley, oats and rye. A set of explanatory variables is used in a pooled regression to explain variations in these price volatilities. With low cereal stocks, supply (yield) shocks (defined here as volatilities, as for the price volatilities) mostly influence inter‐annual volatility while other influential factors are the crude oil price and exchange rate. Cereal demand and interest rate shocks combined with low stocks affect intra‐annual volatility, while other explanatory factors include exchange rate and crude oil price shocks. The derivatives market activity appears to have no significant effect on either intra‐ or inter‐annual volatility. In contrast, large cereal stocks and a well‐functioning international cereal market reduce the effects of shocks in the explanatory variables on both intra‐ and inter‐annual volatilities.     

“经济人”假设的发展基础及现实价值——与任志军商榷

经济学家们不断修正和发展“经济人”假设,是因为它具有不可否定的合理性和科学性。“经济人”假设对我国市场经济条件下的制度建设无疑具有现实价值。     

公司治理内生性研究述评与展望

近年来,公司治理领域的研究取得了丰硕成果,但对于公司治理内生性的研究还缺乏系统性。首先从理论上对公司治理内生性进行了介绍,然后从实证研究角度对公司治理内生性进行了详细阐述,指出了工具变量法与2SLS关系,丰富了公司治理内生性研究。在此基础上,对以往公司治理内生性研究进行了梳理与评析,并对公司治理内生性研究的未来发展趋势进行了展望。     

‘Tour me onshore’: understanding cruise tourists’ evaluation of shore excursions through text mining

ABSTRACT

The aim of this paper is to shed light on the elements underlying cruise tourists’ evaluation of shore excursions, approaching them as an interaction of expressive and instrumental components.

To fulfil the aim of the investigation, a thematic content analysis of 1296 online reviews was conducted using the text-mining software Leximancer. The results of the study revealed that cruise visitors with different overall satisfaction with their guided tour focus the narrative of their opinion on different tour attributes. Thus, the dominant themes of the cruise passengers delighted with their tour included the performance of the tour guide, the arrangement of the tour, as well as the cruise destination sightseeing. On the other hand, instrumental components such as crowded bus tours, limited time at the port of call, and inadequate excursion design appeared to be the main aspects appointed by those unsatisfied with their onshore experience. Furthermore, the study assessed and compared the perceptions of the tour experience across cruise passengers from the contemporary, premium and luxury cruise line segments.
