The veto mechanism in atomic differential information economies

We establish new characterizations of Walrasian expectations equilibria based on the veto mechanism in the framework of differential information economies with a complete finite measure space of agents. We show that it is enough to consider the veto power of a single coalition, consisting of the entire set of agents, to obtain the Aubin private core. Moreover, we investigate on the veto power of arbitrarily small and big coalitions, providing an extension to mixed markets of well known Schmeidler (1972) and Vind’s (1972) results in terms of Aubin private core allocations.     

水管冷却热传导计算模型能量分析

对水管冷却有限元法和水管冷却等效热传导法的相关性进行了研究,采用同一套有限元网格,仿真分析了混凝土浇筑仓的非稳定温度场和徐变应力场,对比分析了两种水管冷却计算模型计算的混凝土浇筑仓平均温度和弹性应变能及黏性应变能.水管冷却等效热传导法计算的混凝土平均温度与水管冷却有限元法计算的平均温度接近,前者是后者的等效平均,但两者的同一节点温度不一样,且差异有时还比较大.由于前者是后者温度的等效平均,所以前者和后者的弹性应变能和黏性应变能接近,但两者的同一节点的应力不一样,因此其差异有时也比较大.     

Is the Dutch consumer a true ricardian?

Summary In this paper the intertemporal optimization approach is adopted in order to estimate an empirical version of Blanchard's (1985) overlapping generations model. The observed sluggishness in consumption is incorporated into the model by recognizing both durability and habit formation as relevant determinants of total consumption. The model is estimated using quarterly data for The Netherlands from 1969:I to 1990:IV. The empirical estimates suggest that the status of the Dutch consumer as a true Ricardian is unambiguously rejected. The results furthermore suggest that this rejection is due to the existence of both liquidity constraints and finite planning horizons.Comments by Peter Broer, Jeroen Kremers, Debora Molenaar, Rick van der Ploeg, Frans Spinnewyn, Casper de Vries, Ed Westerhout and two anonymous referees are very much appreciated. Elbert Dijkgraaf has provided invaluable research assistance. We also thank participants of the OCFEB workshop and the CES seminar at the K.U. Leuven for their comments.     

论会计趋同化与差异性

经济全球化和国际资本市场的持续发展,迫切需要会计信息可比性的提高,会计全球趋同遂成为跨国上市和发行证券及其监管的必然要求。会计趋同首先是形式趋同,即准则层面的趋同。会计形式趋同能否带来实质趋同,即会计实务的一致和会计信息的可比?移植的国际财务报告准则(IFRS)及与国际趋同的国家会计准则是否能够得到有效、一致的执行?特别是国际金融危机的爆发,引发了新一轮国家保护主义思潮。受到金融危机重创的国家,其企业在执行国际趋同的准则中极可能存在操纵行为,从而在一定程度上消减准则趋同的效果。为此,本文探讨了会计趋同化以及与之密切相关的差异性问题,并对本领域的研究及进展予以简要回顾,以期提起准则趋同下会计差异性的认识。     

A note on different models of stochastic processes dealt with in the collective theory of risk

Abstract

1. For the definition of general processes with special regard to those concerned in Collective Risk Theory reference is made to Cramér (Collective Risk Theory, Skandia Jubilee Volume, Stockholm, 1955). Let the independent parameter of such a process be denoted by τ, with the origin at the point of departure of the process and on a scale independent of the number of expected changes of the random function. Denote with p(τ, n)dt the asymptotic expression for the conditional probability of one change in the random function while the parameter passes from τ to τ + dτ: relative to the hypothesis that n changes have occurred, while the parameter passes from 0 to τ. Assume further—unless the contrary is stated—that the probability of more than one change, while the parameter passes from τ to τ + dτ, is of smaller order than dτ.     

生态翻译学视角下高校简介英译的语用等效研究——以河南省地方高校网页中简介英译为例

随着全球化趋势的发展,许多高校为谋求更广泛领域的国际交流合作,纷纷推出学校简介的英语译文,由于各种原因,有些译文存在着不少问题。试从生态翻译学视角,探讨高校网页简介中英译如何从语言维、文化维及交际维层面真正实现语用等效。     

“美国—影响中国家禽产品进口的 某些措施”争端研究

"美国—影响中国家禽产品进口的某些措施"案是中美贸易争端中首起直接涉及WTO《卫生与植物检疫措施协定》(《SPS协定》)的争端。此争端源于美国国会依据《2009年综合拨款法案》第727条禁止美国农业部制定从中国进口家禽产品的规则。本争端涉及3个核心问题:一是SPS措施的认定问题;二是专家组的管辖权(职能范围)问题;三是SPS措施的对等承认问题。但归根结底第727条违反了WTO非歧视性原则。该争端说明,推进我国与其他国家(包括美国)检验检疫机制的对等互认是我国稳定和扩大外贸出口的重要手段。     

Macroeconomic interdependence under incomplete markets

This paper uses a two-country, flexible-price model with overlapping generations of infinitely lived households to study the role of net foreign asset dynamics in the propagation of productivity shocks. Absence of Ricardian equivalence ensures existence of a unique steady-state level of net foreign assets, to which the economy returns following temporary shocks. Model dynamics are significantly different from those of a setup in which terms of trade movements perform all the international adjustment and net foreign assets do not move. The difference relative to a complete markets economy in which net foreign asset movements play no role in shock transmission is smaller. It is amplified if the substitutability across goods rises and if shocks are permanent.     

Leveraging Equity Across The Brand Portfolio

Industry informants suggest that the equity of well-known, established brands can be leveraged to create value for unfamiliar or less-established brands. To the extent that cues in the retail environment imply some commonality between the high-equity brand and the less-established brand, benefits to the less-established brand may be expected. We refer to this implied commonality as strategic equivalence. Sharing the retail brand portfolio with high-equity brands is one way of establishing strategic equivalence. Display structure—whether the brands are displayed separately or intermixed—can also affect perceptions of strategic equivalence. In two studies, we demonstrate the ability of high-equity brands to increase the value of lower-equity brands in the same retail department and the ability of display structure to moderate this effect.     

Measuring Corporate Citizenship in Two Countries: The Case of the United States and France

Based on an extensive review of the literature and field surveys, the paper proposes a conceptualization and operationalization of corporate citizenship meaningful in two countries: the United States and France. A survey of 210 American and 120 French managers provides support for the proposed definition of corporate citizenship as a construct including the four correlated factors of economic, legal, ethical, and discretionary citizenship. The managerial implications of the research and directions for future research are discussed.
