Optimal linear estimators of location and scale parameters using order statistics and related empirical Bayes estimation

Summary

An estimator which is a linear function of the observations and which minimises the expected square error within the class of linear estimators is called an “optimal linear” estimator. Such an estimator may also be regarded as a “linear Bayes” estimator in the spirit of Hartigan (1969). Optimal linear estimators of the unknown mean of a given data distribution have been described by various authors; corresponding “linear empirical Bayes” estimators have also been developed.

The present paper exploits the results of Lloyd (1952) to obtain optimal linear estimators based on order statistics of location or/and scale parameter (s) of a continuous univariate data distribution. Related “linear empirical Bayes” estimators which can be applied in the absence of the exact knowledge of the optimal estimators are also developed. This approach allows one to extend the results to the case of censored samples.     

ECONOMIC SANCTIONS REVISITED: ADDITIONAL INSIGHTS INTO WHY THEY FAIL

Economic sanctions have a poor track record in achieving their objectives. In most cases, they are ineffective in bringing about policy change, cause increased suffering in the sanctioned country and reduce opportunities for business. This paper provides additional insights into why sanctions fail by examining two overlooked factors: power–dependency theory and pressure for political stability.     

Myanmar

Myanmar is one of the few remaining Southeast Asian nations that is seeking to re‐establish itself as an economic force in the region. To achieve this, many of the economic reforms in the 1990s were directed toward the opening up of its economy and allowing the market forces to work. We look at some of the present conditions facing foreign businesses and the unique market of Myanmar. The nation's background, economic conditions, and the market conditions facing both the consumers and businesses are discussed. ? 2001 John Wiley & Sons, Inc.     

An International Perspective of Online Disclosure Presentation: A Comparison of Banner Ad Disclosures from United States, United Kingdom, and Singapore Web Sites

Effective online disclosure presentation is an important feature in banner advertising worldwide. The U.S. Federal Trade Commission (FTC) is viewed as the leader in providing guidance for making disclosures clear and conspicuous. This study examines the extent to which banner ads in the top 100 web sites in three countries with a shared language and intertwining legal and self-regulatory systems—the United States, United Kingdom, and Singapore—adhere to FTC guidance. The lack of systematic differences across countries suggests the need for disclosure research from a global perspective that takes cultural and linguistic differences into account.     

Consumer Perceptions of the Antecedents and Consequences of Corporate Social Responsibility

Perceptions of a firm’s stance on corporate social responsibility (CSR) are influenced by its corporate marketing efforts including branding, reputation building, and communications. The current research examines CSR from the consumer’s perspective, focusing on antecedents and consequences of perceived CSR. The findings strongly support the fact that particular cues, namely perceived financial performance and perceived quality of ethics statements, influence perceived CSR which in turn impacts perceptions of corporate reputation, consumer trust, and loyalty. Both consumer trust and loyalty were also found to reduce the perceived risk that consumers experience in buying and using products. From these significant findings, we draw several conclusions and implications, including the importance of enhancing firm focus toward its ethical commitment and long-term reputation.     

The Commodification of Race in Singapore: The Customer Service Implications of the Other-Race Effect on Tourism and Retailing

This paper examines the phenomenon known as the other-race effect, which is the ability to recognize the faces of those of one race, easier than the faces of those from another race. Typically, the race that is easier to recognize is the individual's own race, and most previous research has focused on this type of comparison. This study, though, analyzes the ability of Chinese Singaporeans to recognize the faces of people of color versus White faces in a customer service context, and compares those results with the ability of White subjects in the United States to recognize the same faces. This approach is particularly applicable to the Asia Pacific region. Tourism accounts for a significant part of the regional economies, and marketers are becoming more sensitive to the changing needs of the multicultural marketplace where inter-racial interactions between customers and service providers in retailing and tourism are on the rise. Results of the research indicate evidence of the other-race effect. Asians who were more exposed to people of color than to Whites, recognized Black faces better than White faces. The results are interpreted based on the theoretical premise that people are better at recognizing faces of races for which there is a higher level of interaction, exposure, and familiarity.     

An Investigation of the Characteristics of Australian Charitable Donors

Ads using a range of emotional appeals have been used in different donation campaigns, but, if not managed well, can evoke anger and irritation and as a result alienate potential donors. An understanding of the key donors’ demographics, psychographics, and perception of charities can then help build a better advertising campaign toward donation intention. This research therefore aims to investigate this proposition by building and extending on previous research on an Australian sample. The sample was randomly drawn from the Australian White Pages, and identified respondents were mailed a self-administered survey. Results showed that donors are likely to be older and less highly educated. Religiosity was found to have low influence on charitable donations. Australian donors were also more likely to have positive attitudes toward international charities as opposed to national charities. Further research should focus on cross-country comparisons of donor characteristics to provide a more holistic perspective on donor behavior and thus assist managerial decisions in the marketing of charities.     

Protecting children's privacy online: How parental mediation strategies affect website safeguard effectiveness

Concern toward children's safety in an online environment has resulted in demands for safeguards to protect their online privacy when involved with a wide variety of commercial websites. Unfortunately, little academic research has examined how effective safeguards are in limiting children's disclosure of information. We fill this void by examining how proposed safeguards may interact with various types of parental involvement in limiting children's willingness to disclose information online. The results of two studies involving preteen, young teen, and older teen children show that safeguard effectiveness depends on both the type of parental mediation and the particular age group. Implications are presented for retailers, educators, and parents.     

“Natural” and “Fresh”: An Analysis of Food Label Claims in Internationally Packaged Foods in Singapore

Food claims invite controversies on account of their potential to mislead consumers while at times masquerading as health information devices. In the United States, Europe, and Australia/New Zealand, scholars have extensively studied the prevalence of food claims, the regulatory repercussions, and effects of such claims on consumers’ food perceptions and dietary choices. Our study is an attempt to address a gap in related research focused on Asia by situating the inquiry in Singapore where consumers are exposed to a wide variety of such claims due to the universality of food imports. This study examines the state of food claims by the food product’s region of origin, and focus specifically on the use of terms “natural” and “fresh” on food labels. We present recommendations for food marketing policymakers and practitioners.     

Pirating Pirates of the Caribbean: The curse of cyberspace

Abstract

This study investigates the factors influencing the ‘illegal’ downloading of films and TV series through peer-to-peer (P2P) networks. Specifically, it examines how social and ethical orientations and attitudes towards downloading impact on downloading intentions. The neutralisation theory and theory of planned behaviour are used to underpin the research framework. The data analysis of 284 usable responses produced several significant relationships. Facilitating conditions, social factors, collectivism, and personal moral obligation were found to predict attitudes towards ‘illegal’ downloading. Social factors, collectivism, personal moral obligation, and attitudes towards ‘illegal’ downloading were also found to influence intentions to download. The findings derived from this study will provide marketers and policymakers with strategic and managerial initiatives to counteract this persistent problem.
