ESTIMATION OF ENGEL ELASTICITIES FROM THE BOX-COX ENGEL FUNCTION

A general type of Engel function which can be called the Box-Cox Engel function is developed. This function is used to estimate the relationship between the dependent and explanatory variables for which many commonly used Engel functions become special cases. The Maximum Likelihood (ML) method is used to estimate its parameters using grouped Household Expenditure Survey (HES) data. These estimated parameters are then used to estimate Engel elasticities for total food and various non-food items. The Box-Cox Engel function is also used to discriminate among the commonly used Engel functions, by performing a parametric test on the power parameters. A joint test on the different power transformation has been done by the likelihood ratio test and it turns out that none of the commonly used Engel functions are appropriate for the Australian HES 1975-76 data, although the double log Engel function is not significantly different from the Box-Cox Engel function for five out of ten consumption items.

The effect of automated service quality on bank financial performance and the mediating role of customer retention

The impact of automated service quality on bank financial performance and the mediating role of customer retention have received little attention, as scholars have focused on issues of usability and measurement. This study begins by showing the impact of technology on the way banks conduct business and proceeds to discuss automated service quality definitions and the potential influence of automated service quality on retention and financial performance. A mediating model that links service quality to bank financial performance through customer retention in the automated service context is proposed. The results of this empirical study confirm the role of customer retention as a mediator in the effect of automated service quality on financial performance. Implications of the findings are discussed and the limitations of the study and the potential for future research are considered.     

The relationship between Arab values and work beliefs: An exploratory examination

In this study, 365 employees from three Middle Eastern countries (Saudi Arabia, Kuwait, and Oman) are queried about their cultural values and work‐related beliefs. This analysis is unique both in its sample and its focus on the relationship between individual cultural values and beliefs about work. Results suggest that the cultural value dimensions individualism (p < .001) and masculinity (p < .001) are related to both an individual's beliefs about organizational commitment and work ethic. Additional findings reveal patterns between cultural values and humanistic and political beliefs. Future research directions and managerial implications are also discussed. © 2002 Wiley Periodicals, Inc.     

Ethical attitudes of mental health practitioners: Balancing therapeutic practices and treatments

This paper reports the responses of 251 mental health care practitioners to a mail survey examining their views concerning ethical conflicts and practices within their work environments. Besides identifying the sources and types of conflicts they experience, respondents were asked how ethical standards have changed over the last 10 years as well as the factors influencing these changes. Conclusions and implications are outlined and future research needs are described.Mohammed Y. A. Rawwas is an Assistant Professor of Marketing at the University of Northern Iowa.

Upconing and Saline Water Intrusion and the Need for Water Conservation in the Lower Part of Wadi Fatimah,Western Saudi Arabia

Shallow aquifers were exploited in western Saudi Arabia a long time ago in history. In the last five decades, and under the conditions of an increasing supply of water, many new wells were drilled at relatively deeper intervals than the hand-dug wells of the time. In the downstream part of Wadi Fatimah, and over time, more saline water has been brought up in a number of wells. Overexploitation of groundwater for industrial and agricultural purposes has led to the appearance of two phenomena responsible for the salinization-upconing and saline water intrusion. Upconing occurs in separate pockets while saline water encroachment affects the lower part of Wadi Fatimah and the area towards the Red Sea coast. This article deals with the identification and delineation of areas affected by each of the two phenomena. The methodologies used in this work are mainly hydrogeological and hydrochemical. Resistivity surveys helped in delineating the fresh water-saline water interface. Methods to control upconing and saline water intrusion are suggested to safeguard the aquifer from further contamination. Effective conservation measures are recommended for the protection of groundwater resources in Wadi Fatimah.     

International Market Entry Strategies of Emerging Market MNEs: A Case Study of Qatar Telecom

ABSTRACT

Drawing on existing theoretical perspectives and previous research, this study essentially investigated the strategic motives, location choice, and international entry mode strategies of emerging market multinational enterprises based on a case study of a telecom company, Qatar Telecom (Qtel) from the Gulf Cooperation Council. Using empirical findings from the semi-structured interviews, this study has clearly indicated that the main strategic motivation behind Qtel's internationalization was essentially opportunity seeking in terms of enabling market development and generating higher return on investment. Although Qtel used different entry strategies depending on the characteristics of host country markets, the company is more in favor of mergers and acquisitions than greenfield investments.     

Chief executive officers' dispositional optimism,host country's rule of law,and foreign market equity mode choice of Ghanaian small and medium‐sized enterprises

Despite a growing interest in the influence of managerial characteristics on firms' strategic decision‐making process, scholarly knowledge is limited with regard to how and when psychological attributes of executives affect firms' foreign entry mode decision. Building on behavioral decision‐making theory, we address this gap by investigating the effect of chief executive officers' (CEOs') optimism on firms' foreign market equity mode choice. In addition, we examine the moderating influence of the host country's rule of law on this relationship. Using primary data from 227 small and medium‐sized enterprises (SMEs) in Ghana, we found that increases in the levels of CEOs' optimism are related to the increases in preference for equity entry mode. This relationship is amplified when CEOs perceive the host country to have stronger rule of law. The findings have theoretical, managerial, and policy implications for SMEs' foreign market entry mode strategy.     

Determinants of market price of stock： A study on bank leasing and insurance companies of Bangladesh

Financial firms make up a substantial fraction of the domestic equity market. A number of studies subsequently used different conceptual and methodological approaches to model equity return of financial services firms. Movement of the stock price as the consequence of the movement of the micro and macroeconomic factors is strongly supported by the literature review. Dhaka Stock Exchange in Bangladesh is inefficient in weak form. Multiple regression analysis is conducted to find out the relationship microeconomic factors with the stock price. In this study found a significant linear relationship among market return and some microeconomic factors such as net asset value per share, dividend percentage, earning per share of bank leasing and insurance companies. Also found non-linear relationship among the variables is insignificant at 95 percent level of significance.     

Determinants of Demand for Delivery Services in Sudan: An Empirical Investigation with Reference to Khartoum State, 2004*

Abstract: Using multinomial logistic methods, we examined the determinants of the delivery care seeking behavior of women in Khartoum State of Sudan, as well as the impact of changes in the attributes of public delivery services on the market shares of delivery services. Time distance and transportation cost have significant negative effects, while the random ‘quality’ coefficient is positive but not significantly different from zero. Further, the likelihood of choosing home over public delivery services increases with order of birth. The positive effects of women's education and household income are most important for those who prefer private over home delivery whereas the use of modern antenatal services is decisive in choosing modern over home delivery. Also, shifts in demand toward public delivery services resulting from improvements in quality and qualifications of medical staff might be undermined by the reduction in demand emanating from a rise in the order of delivery, time distance and transportation cost to public delivery institutions. The income effects are more pronounced, particularly for the share of private delivery services. Educated women tend to shift from home to modern delivery services.
