Random effects probit and logit: understanding predictions and marginal effects

Random effects probit and logit are nonlinear models, so we need predicted probabilities and marginal effects to communicate the economic significance of results. In these calculations, how one treats the individual-specific error term matters. Should one (i) set them equal to zero or (ii) integrate them out? We argue that (ii) is the quantity that most readers would expect to see. We discuss these in the context of the statistical package Stata, which changed its default predictions from (i) to (ii) in version 14. In Appendix 5, we illustrate how to calculate predictions and marginal effects using method (ii) in Stata 13 and earlier.     

Understanding How Goal‐striving,Goal Orientation,and Shame Influence Self‐perceptions after Exposure to Models in Advertising

Marketers frequently use advertisements featuring thin models to promote the goal of self‐improvement to consumers. However, many of these appeals lead to detrimental effects on the self‐perceptions of the females who view them. This paper integrates components of goal‐striving theory and social comparison theory to explain consumer response to these advertisements and investigates how goal attainability may mitigate the negative effects of these ads. Additionally, this work investigates how a promotion‐focus goal orientation moderates the effects of the goal‐striving process and provides evidence of the mediating effects of shame. Finally, this work addresses a gap in the literature by examining how the interplay of model size and goal attainability impacts male consumers’ self‐perceptions. Study 1 reveals that high levels of perceived goal attainability mitigate the negative effects of exposure to thin models on self‐perceptions for females. Study 2 demonstrates that a high promotion‐focus goal orientation can lead to more favorable self‐perceptions for female participants exposed to a thin model with attainable goals, but it does not isolate participants from feelings of shame, which mediates the effects of goal attainability on self‐perceptions. Study 3 reveals similar findings for male consumers, but notably finds that shame does not play a significant role in understanding the comparison process for male consumers, suggesting key differences in the comparison processes between sexes.     

Malleability of taste perception: biasing effects of rating scale format on taste recognition,product evaluation,and willingness to pay

Product-related cues, such as brand or price, can influence consumers’ taste perception. Going beyond this observation, we examine the extent to which a stimulus-extrinsic factor, such as the format of the measurement tool on which consumers describe attributes of a taste sample, influences concurrent taste perception, and in turn, later taste recognition, overall product evaluation, and willingness to pay (WTP). The results of two experiments show that rating scale format (i) influences consumers’ concurrent impression of a taste sample, (ii) systematically biases later identification of the sample in a taste recognition test, and (iii) affects overall product evaluation and WTP. However, scale format (iv) does not influence ratings and downstream judgments when consumers are highly knowledgeable in the product domain. These findings demonstrate that the experience of taste is fleeting and not well represented in memory, and that like other subjective experiences, taste needs to be reconstructed based on accessible cues.     

The Invisible Meets the Intangible: Culture’s Impact on Intellectual Property Protection

In the global marketplace of ideas, accusations are often made that certain countries refuse to protect intellectual property (IP). This accusation fails to account for cultural differences in the recognition of IP This paper considers the impact of cultural variables upon a nation’s level of (IP) protection. Cultural variables such as humane orientation and in-group collectivism have a negative impact upon IP protection, while uncertainty avoidance and future orientation have a positive impact upon IP protection. Managerial implications of these findings are discussed.     

Arresting the Killer in the Kitchen: The Promises and Pitfalls of Commercializing Improved Cookstoves

In a shift exemplary of neoliberal approaches to development, major funders of household energy interventions have begun to emphasize market-based stove dissemination over partially subsidized models. Stove promoters are increasingly expected to operate as self-sustaining businesses. This shift is viewed as a way to “scale-up” in order to reach millions of poor households lacking access to clean cooking technologies. Using the case of GIRA, an NGO that has successfully distributed cookstoves in Mexico’s Central Highlands for nearly two decades, we demonstrate how this trend presents challenges for organizations operating effectively with outside funding in highly contextual local conditions.     

The influence of licence status on Kansas child fatalities due to motor vehicle crashes

The influence of driver licensure on child motor vehicle crash (MVC) deaths in Kansas was investigated. Fatalities from 1994-2000 due to MVCs were extracted from the Kansas State Child Death Review Board and the Fatality Analysis Reporting Systems databases. It was found that 14% (52 of 363) of child fatalities from MVCs in Kansas occurred in vehicles where the driver was not licensed. Driver licence status was associated with use of safety restraints, the victim's age and race, weekend driving and rural county location. All child deaths involving unlicensed drivers were preventable. New legislation on vehicle sanctions may be required to assist law enforcement. Safety restraint laws should be enforced and promoted to the public. Transportation options are necessary for unlicensed drivers, particularly if they have young children and live in a rural community. Thus, a multi-system approach involving law enforcement, accident prevention strategies and transportation options will save the lives of children.     

Self-Service Technology and the Service Encounter

Self-service technology is affecting the service encounter. The potential reduction in personal contact through self-service technology may affect assessments of consumer satisfaction and commitment, making it necessary to investigate self-service technology usage, particularly the long-term impact on consumers' relationships with service organisations. Thus, this paper presents a framework for investigating the impact of self-service technology on consumer satisfaction and on a multi-dimensional measure of consumer commitment. Illustrative quotes from exploratory in-depth interviews support the framework and lead to a set of propositions. Future research directions for testing the framework are also discussed, and potential implications of this research are outlined.     

What Women Managers Want: Customising Human Resource Management Practices

Amanda Sinclair and Jill Ewing report on a detailed study of women managers in a large retailing organisation to discuss why women are a poorly utilised and misunderstood reserve of managerial talent. They identify three main groups- ‘family first job occupants’, ‘mature career traditionalists’ and ‘career-family committeds’- and show how each has different aspirations and correspondingly different attitudes to organisational incentives. the message to policy-makers is that they need to ‘customise’ their practices in order to relaise benefits both for their women managers and their organisations. Amanda Sinclair is Associate Professor in Organisational Studies at the Graduate School of Management of the University of Melbourne. Jill Ewing is a postgraduate student in the same university and a Senior Research Assistant at the Key Centre for Women's Health in Society.
