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.     

Case study—Embodied virtual agents: An analysis on reasons for failure

Despite very optimistic academic and professional literatures, embodied virtual agents (EVA) on commercial websites do not seem to keep all their promises. An update in December 2009 of a benchmark led by OrangeLab in 2007 on embodied agents displayed on French websites reveals that more than 60% of them have actually disappeared. This case study deals with understanding the disappearance of embodied virtual agents thanks to a literature review, a benchmark of 80 agents on French commercial websites and an analysis of experts' in-depth-interviews. This work identifies a series of common errors in the agents design – namely, appearance inadequacy and lack of intelligence and autonomy – that creates a gap between consumers' expectations and agents' performance explaining agents' lack of success. As a conclusion, this case study gives practitioners actionable advices to design future agents by highlighting the characteristics of the ideal virtual sales agent (VSA).     

Access to credit and heterogeneous effects on agricultural technology adoption: Evidence from large rural surveys in Ethiopia

Modern agricultural technologies hold huge potential for increasing productivity and reducing poverty in developing countries. However, adoption levels of these technologies have remained disappointingly low in Africa. This paper analyzes the effect of access to credit on the likelihood of adoption and use intensity of chemical fertilizers using data from large rural surveys in Ethiopia. Using a heteroscedasticity-based identification strategy to address the endogenous nature of access to credit, we find that access to credit has significant positive effects on adoption and intensity of use of chemical fertilizers. However, important heterogeneities are observed. Credit obtained from formal sources is more important for the intensity of use than for the decision to adopt chemical fertilizers. Credit taken with the primary purpose of financing agricultural inputs is more likely to promote adoption of chemical fertilizers than credit taken per se. Furthermore, reported credit effects are larger when estimated against the sample of credit-constrained non-users as compared with the pool of the whole sample of credit non-users. The results remain robust to several sensitivity analyses. Our results yield useful implications for the design, promotion, and targeting of credit services to leverage their effect on adoption of agricultural technologies.     

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.

Managerial Behavior and the Link between Stock Mispricing and Corporate Investments: Evidence from Market‐to‐Book Ratio Decomposition

We examine the impact of mispricing on corporate investments and its components: capital expenditures, research and development, acquisitions, and asset sales. By decomposing the market‐to‐book ratio into mispricing and growth components, we show that corporate investments are linked to mispricing through market‐timing and catering, after controlling for growth and financial slack. This investment‐mispricing link is more pronounced in financially constrained firms and in firms with short‐horizon shareholders. Overall, our study indicates that the sensitivity of investments to mispricing is a function of the nature of mispricing, the type of investment, and the firm's characteristics.     

Consumer Ethics: A Cross-Cultural Study of the Ethical Beliefs of Turkish and American Consumers

The ethical climate in Turkey is beset by ethical problems. Bribery, environmental pollution, tax frauds, deceptive advertising, production of unsafe products, and the ethical violations that involved politicians and business professionals are just a few examples. The purpose of this study is to compare and contrast the ethical beliefs of American and Turkish consumers using the Ethical Position Questionnaire (EPQ) of Forsyth (1980), the Machiavellianism scale, and the Consumer Ethical Practices of Muncy and Vitell questionnaire (MVQ). A sample of 376 subjects that consists of American consumers (n = 188) and Turkish consumers (n = 199) was used to compare the ethical beliefs and practices of the two samples. The MANOVA results for the two nationality groups found that five out of six criterion variables differed between the two groups. The implications of this study are intended to assist marketers to develop strategies that suit a particular market and lessen their risk of entry. Mohammed Y.A.

The expansion of early childcare and transitions to first and second birth in Germany

We use quasi-experimental expansion of publicly funded childcare slots for children under the age of three from Germany and exploit regional variations of this large-scale expansion to account for endogenous and selective fertility decisions. To account for left and right censoring, we implement this quasi-experimental framework into the setting of the semiparametric Cox hazard model. By using spatial data on childcare provision at the level of counties and microdata from the German Socio-Economic Panel (SOEP) from 1998 to 2012, we find a significant increase in the transition probability to first birth by 11.9% for native childless couples who were in the labor force before childbearing. With regard to transition to the second birth, however, no significant effect is found from the increase in childcare slots. With a particular focus on the transition to first birth, the effects are demonstrated not to be driven by selective residency choices and internal migration patterns. Furthermore, a large set of robustness checks is applied to show that highly educated mothers react the most, while effects are not attributable to the upper decile of income distribution.     

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.     

Religious commitment related to message contentiousness

Using an experimental design, we tested whether viewers with differing levels of religious commitment have differing unaided recall, aided recall and attitudes towards non-contentious and contentious TV commercials in terms of their perceived message cues. The study, using Bahrani Muslim interviewees, demonstrates that religiously stricter Muslims have significantly lower recall and a more negative attitude towards messages perceived as contentious, while their recall and attitude scores for non-contentious messages are similar to those of subjects with lower levels of religious commitment. We recommend that international marketers show increased sensitivity to the cultures and traditions of submarkets by manipulating message cues, like music and dancing, to strengthen the brand communication while retaining its strategic integrity.
