经济人的“再生”:对一种新综合的探讨与辩护

本文力图对经济学帝国主义现象中复兴的新经济人提供一个较明确的描述,纠正倡导者和批评者共通的某些误解。本文的重点是:通过把社会偏好、个人社会价值等概念引入经济人模型的讨论之中,给能纳入这一分析范式的行为(特别是利他行为)确定某些标准;重新界定经济人在不同层次上的理性行为特征,以说明赋予经济人的理性程度将取决于所研究的主题的具体情形;进而,讨论经济人的标准原型及其变型在理论分析中各自适用的范围和局限性。     

How uncivil customers corrode the relationship between frontline employees and retailers

This study investigates the effects of customers’ uncivil treatments on frontline retail employees’ emotions, deviant behaviors and relationship with the retail organization. Our theoretical model is based on both marketing and personnel management literatures. 415 frontline retailing American employees answered our questionnaire. Employees treated uncivilly by customers feel angry but have to hide their negative emotions, which leads them to emotional exhaustion and deviant behaviors. Paradoxically, employees’ strong commitment to their retailing organization brings about more deviant behaviors. We propose some managerial strategies to cope with uncivil customers, as well as future research on this important and under-researched topic.

Individual differences in assessing problem similarity

This paper reports on a study which investigates the potential influence of perceptual differentiation (PD) ability on introductory accounting students' ability to identify and use analogies to solve problems. Accounting students with differing levels of PD ability first studied two sample problems with solutions which provided potential source analogues for analogical transfer. They then attempted to solve two analogous accounting problems differing only in the criteria for identifying problem analogousness. Findings suggest that PD ability may influence a problem solver's ability to identify analogous problems by affecting which problem features (surface or structural) he or she is likely to attend to and use for assessing problem similarity and potential analogousness. The paper concludes by discussing implications for pedagogical practices in accounting.

New technology and the urban environment

Technology has always had an influence on the form of settlements, but only since the coming of Information Technology has it aroused much interest from academics and planners. The impact that IT is likely to have on urban areas is debated, some foreseeing decentralisation and the end of place, while others see evidence of the centralisation of control in a global economy. Other new technologies may also affect cities as new materials provide the opportunity for different styles of building. As we enter the 21st century, however, we do so with the largest stock of urban capital ever, much of which is ageing and in need of maintenance. Technology is part of a complex interrelationship of influences on urban areas and much of it will have to be retrofitted on to the pre-existing environment.

Urban sprawl factors in the surface water resource basins of Istanbul

This paper presents the reasons for uncontrolled land-use changes in the water resource basins of Istanbul. These changes are evaluated with a Geographical Information System (GIS), using four Landsat (1990, 1995, 2000, 2005) satellite images. Additional spatial information about capital improvement projects (highways and the Bosporus bridges), industrial land-use decisions, land ownership, and jurisdictional boundaries is also utilized. We observe that the most critical land-use changes have occurred in places with higher accessibility, mostly in close proximity to the metropolitan city center. The literature describes large public capital improvement projects (primarily the Trans European Motorway – TEM) as the primary reason for a trend of illegal occupation of public lands; however, the TEM should not be considered as the sole reason. This study explores other possible causes for these illegal developments in the water resource basins, grouped into three broad dimensions physical, socio–economic–political, and legal. Finally, we put forward possible policy suggestions for the preservation of the limited surface water resource basins in Istanbul.     

ECONOMIC IMPLICATIONS OF POLICY RESTRICTIONS ON WATER WITHDRAWALS FROM SURFACE AND UNDERGROUND SOURCES

The appropriation of water for economic activities is limited by regional surface and underground endowments, and symptoms of environmentally unsustainable withdrawals are already visible in many regions of the world. In this paper we investigate the economic implications of water policy imposing source- and region-specific restrictions on water withdrawals taking the Mexican economy as a case study. We use an inter-regional input–output model of Mexico's hydro-economic regions to allocate production subject to the availability of water and other factors of production. Water sustainability requires a reduction of 7.5?km³/yr of groundwater withdrawals, which is compensated by an increase of 3.4?km³/yr of surface water, an expansion onto an additional 1.4 million hectares of rainfed land, and modifications in subnational patterns of food trade. This framework for evaluating scenarios describing sustainability-oriented water policies is readily applicable to other regions.
