The causal relation between government revenue and spending: Evidence from Egypt and Jordan

In investigating the causal relation between government revenue and spending, our empirical results support the tax-and-spend hypothesis for Egypt and the fiscal synchronization hypothesis for Jordan. Breaking away from these historical trends is essential for both countries to eliminate the budget deficit and therefore ensure the availability of domestic saving for private investment. To cope with unemployment and poverty, continuing privatization is recommended for both countries to improve productivity and efficiency in the domestic economy. Privatization should lead to higher domestic saving and investment and at the same time eliminate the budget deficit by enhancing revenue and curbing spending. (JEL H62, H63)     

Nash-equilibria in a heterogeneous oligopoly with fuzzy information

We consider a model of an oligopolistic market with heterogeneous firms and products where neither the cost nor the demand functions are common knowledge. Instead, each firm only has some vague ideas about the price strategies adopted by its competitors which is modelled by a fuzzy set. In analogy to the notion of an "equilibrium of actions and beliefs" we define and characterize a generalized Nash-equilibrium and show its existence under general conditions. Furthermore, the impact of the fuzzy information on the equilibrium outcome is analyzed by means of a comparative static analysis within a particular model framework.Received: 28 May 2002, Accepted: 25 December 2002, JEL Classification: D43, D80, L13We wish to thank Bernhard F.

A note on the determination of A-optimal type block designs under fixed and mixed effects models

In this paper, we consider the problem of estimating a selected set of contrasts between v treatments using a block design consisting of b blocks of size k. Traditionally, the construction of A-optimal block designs for such situations has been carried out assuming a fixed effects model. In this paper, we show that A-optimal designs constructed under a fixed effects model are robust in the sense that these designs have maximal minimal efficiency when considered among all available designs and under all possible mixed effects models.

Duration dependence testing for speculative bubbles

Prior research has employed a number of methods to test for speculative bubbles in asset prices, including a method based on the concept of duration dependence. This study explores whether duration dependence tests for speculative bubbles are sensitive to specification decisions. Our results question the efficacy of using measures of duration dependence to test for speculative bubbles. In particular, we find that evidence of duration dependence is sensitive to the method of correcting for discrete observation of continuous duration, the use of value-weighted versus equally weighted portfolios, and the use of monthly versus weekly runs of abnormal returns.

Materialism, status signaling, and product satisfaction

The consumer satisfaction literature has not, for the mos part, integrated individual values into the product evaluation process. Yet a comprehensive understanding of consumer satisfaction can best be attained by including both consumer and product factors. To demonstrate the usefulness of including individual values, this research focuses on one consumer value, namely, materialism. The authors empirically explore how this individual value is linked to consumers’ evaluations of products they have purchased. Using surveys, the authors collected data from a sample of college students (n=211) and a sample of adults (n=270). Across these two studies, using divergent samples and products, they find consistent evidence that materialism is negatively related to product satisfaction in product categories with high potential for status signaling, but unrelated to product satisfaction in product categories with lower potential for status signaling. The consumption goals that produce these product evaluations are empirically addressed Jeff Wang (jianfeng76@yahoo.com; PhD, City University of Hong Kong) is an assistant professor of marketing in the Faculty of Business at the City University of Hong Kong.

His research interests include social networks and consumer behavior, consumer satisfaction and well-being, materialism and consumption meanings, and consumer interests and public policy issues. His dissertation studies credit card debt as a socially embedded phenomenon and investigates how consumers leverage their interpersonal ties as they accumulate and repay their debt.

电力施工企业工程项目全过程成本管控策略

在电网体制改革以及国家政策调整的双重背景下,电力建设市场已经逐渐打破以往的格局,这使电力施工企业不得不参与越来越激烈的市场竞争.但是,由于电力施工企业长期采用粗放的管理模式,人员、材料、机械等各个方面的成本均相对较高,导致其在市场竞争中缺乏优势.对于市场经济来说,企业要想获取竞争优势,主要依靠产品功能和成本两个方面,电力施工企业的产品具有显著的同质性特征,所以成本控制成为电力施工企业提升自身竞争力的主要因素.因此,为了提升电力施工企业的市场竞争力,必须根据实际情况有效落实并不断强化成本管控工作.

对企业财务管理中业财融合的思考

新时代背景下,业财融合是企业战略发展的需要,也是财务人员转型的方向.在传统的会计核算中,一般是先由公司各业务部门将业务数据交给财务人员,财务人员及时进行核算,进而核算出企业的收入、成本和利润等财务数据.在这一过程中,财务人员并不能起到监督作用.原有的财务工作模式已经不再适合当前企业的发展,甚至可以说,在这样的环境下企业很难跟上同行业的步伐.企业要想发展,就必须有效管理企业内外部环境,而财务管理是企业的命脉.因此,实施业财融合是当前环境下财务人员的新方向,更是促进企业精细化管理的有效举措.文章通过分析当前企业存在的问题,提出了业财融合的重要作用和意义,以及打破当前业财融合瓶颈的措施,以供相关人员参考.
