Highway traffic flow and the uneconomic region of production

In this paper highway traffic flow is formulated as a short-run production function in which traffic volume is the output and traffic density is the variable input. Given this formulation, the ‘uneconomic’ region of production is relevant. Often it is the case that traffic density will exceed the point at which traffic volume is at a maximum; i.e., the marginal product of the variable input is negative.     

Reaffirming the CEO effect is significant and much larger than chance: A comment on Fitza (2014)

A recent study by Fitza argued that the prior estimates of the Chief Executive Officer (CEO) effect are conflated with events outside the CEO's control, are largely the result of random chance, and that the true CEO effect is smaller than has been previously estimated. We suggest that the empirical methodology employed by Fitza to support these claims substantially overstates the “random chance” element of the CEO effect. We replicate Fitza's findings, highlight methodological issues, offer alternative conclusions, and using multilevel modeling (MLM), suggest that his analyses mischaracterize the CEO effect.

<Emphasis Type="Italic">GTE Sylvania</Emphasis> and Interbrand Competition as the Primary Concern of Antitrust Law

Footnote 19 of the landmark U.S. antitrust decision in Continental T.V. v. GTE Sylvania, Inc. 433 U.S. 36 (1977) declares that “Interbrand competition … is the primary concern of antitrust law.” We trace the antecedents and influence of this declaration, argue that it is inappropriate, and conclude that it should be abandoned.     

Business models among SMTEs: identifying attitudes to environmental costs and their implications for sustainable tourism

This paper examines how environmental resources and costs feature in business models of small- and medium-sized tourism enterprises (SMTEs). Several studies have pointed to the generally positive nature of the relationship between the economic and environmental performance of tourism firms. Yet, although business models act as a vector between these aspects of firm performance, they have been overlooked in sustainable tourism discourse. The paper reports findings from discussion groups of SMTE businesses in South West England during the global economic downturn. Environmental costs and cost control were afforded relatively little importance in terms of value creation; conversely, there was a strong and predictable emphasis on revenue generation. Indirect tactics emerged for dealing with guests’ environmental behaviours which reflected this prevailing commercial logic. Green credentials were routinely de-emphasized, sometimes regarded as liabilities, in a form of greenhushing. Responses were framed by reference to social media and how online reviews may negatively impact on future value capture. Conceptually, the business model emerged as an important lens for understanding how environmental resources and costs were valourized. The paper highlights the need to ensure that contemporary approaches to environmental management in SMTEs reflect the current and fast-changing conditions that frame business models.     

Profiling employees online: shifting public–private boundaries in organisational life

Profiling involves the collection and use of online information about prospective and current employees to evaluate their fitness for and in the job. Workplace and legal studies suggest an expanded use of profiling and significant legal/professional implications for HRM practitioners, yet scant attention has been afforded to the boundaries of such practices. In this study, profiling is framed as a terrain on which employees and employers assert asymmetrical interests. Using survey data from large samples in Australia and the UK, the study investigates the prevalence and outcomes of profiling; the extent to which employees assert a right to privacy versus employer rights to engage in profiling; the extent to which organisations codify profiling practices; and employee responses in protecting online information. The findings contribute to a small and emerging body of evidence addressing how social media conduct at work is reconstituting and reshaping the boundaries between public and private spheres.     

The Higher Earning in America: Are 529 Plans a Good Way to Save for College?

This article studies whether 529 plans are an effective way for most people to save for college. The 529 plans were created in 1996 to help low- and middle-income American families save for college. Since this time they have adopted more tax advantages and grown substantially as a result. While total balances in 529 plans now exceed $250 billion, less than 3.0 percent of households have a 529 plan. And the majority of 529 plan accounts are held by the wealthiest households. Low- and middle-income households receive little tax savings from investing in 529 plans, and some states count these plans against financial aid. Also, 529 plans are complicated, rules vary by state, and fund management fees tend to be high. Thus, 529 plans are not the panacea to college affordability.     

Ethical sensitivity to stakeholder interests: A cross-cultural comparison

This study applied Hofstede’s typology to examine the effect of culture on ethical sensitivity toward various stakeholders. It was found that uncertainty avoidance had a positive effect and that power distance and individualism/masculinity had negative effects on ethical sensitivity. The results also indicated that ethical sensitivity to stakeholder interests is dependent on which stakeholder is affected. Although Americans and Taiwanese sales agents were equally sensitive to customer interests, the Taiwanese were more sensitive to the interests of their company and a competitor but were less sensitive to the interests of a colleague. This study should prove valuable to international marketers because the cultural typology allows managers to identify differences in work-related values of employees across different nationalities and thus provides a theoretical base for designing more effective sales management practices.

Geography, insolation, and vitamin D in nineteenth century US African-American and white statures

Using a new source of nineteenth century US state prison records I contrast the biological living conditions of comparable African-Americans and whites. Although blacks and whites today in the US reach similar terminal statures, nineteenth century African-American statures were consistently shorter than those of whites. Greater insolation (vitamin D production) is shown to be associated with taller black and white statures and a considerable share of the stature difference between US blacks and whites was attributable to insolation and vitamin D production. Black statures increased during the antebellum period, while white statures declined. Black and white statures both decreased after the Civil War. Farmers were taller than workers in other occupations, and an alternative explanation for stature variation by social class is considered.
