Timing of Sale,Pricing, and Cost Information: Evidence from the Airline Industry*

This study examines the association between when an airline sells its passenger seats and the pricing method (marginal cost or full cost) it employs. Prior literature suggests that when firms are able to change prices during the selling period, the optimality of full cost pricing or marginal cost pricing depends on when demand information is revealed during the period between capacity commitment decisions and time of sale. Full cost‐based pricing is appropriate in determining capacity commitment and prices simultaneously, while marginal cost provides more relevant information for pricing when capacity has been committed. Using the price and cost data from a sample of four U.S. domestic airlines, we find that full cost explains price variations of first‐day sales robustly. The adjusted R² of the marginal cost pricing model is larger in the sample of sales two days prior to departure than in the sample of first‐day sales. In the analysis of the sample of sales two days prior to departure, we find that, based on the adjusted R² of the full cost pricing and marginal cost pricing models, the explanatory power of marginal cost pricing is relatively weaker than full cost pricing. Our results document the use of different cost information along the dynamic change of price and provide implications in understanding the role of cost information in setting prices.     

Extreme jobs: the dangerous allure of the 70-hour workweek

Today's overachieving professionals labor longer, take on more responsibility, and earn more than the workaholics of yore. They hold what Hewlett and Luce call "extreme jobs", which entail workweeks of 60 or more hours and have at least five often characteristics-such as tight deadlines and lots of travel--culled from the authors' research on this work model. A project of the Hidden Brain Drain Task Force, a private-sector initiative, this research consists of two large surveys (one of high earners across various professions in the United States and the other of high-earning managers in large multinational corporations) that map the shape and scope of such jobs, as well as focus groups and in-depth interviews that get at extreme workers' attitudes and motivations. In this article, Hewlett and Luce consider their data in relation to increasing competitive pressures, vastly improved communication technology, cultural shifts, and other sweeping changes that have made high-stakes employment more prominent. What emerges is a complex picture of the all-consuming career-rewarding in many ways, but not without danger to individuals and to society. By and large, extreme professionals don't feel exploited; they feel exalted. A strong majority of them in the United States-66%-say they love their jobs, and in the global companies survey, this figure rises to 76%. The authors' research suggests, however, that women are at a disadvantage. Although they don't shirk the pressure or responsibility of extreme work, they are not matching the hours logged by their male colleagues. This constitutes a barrier for ambitious women, but it also means that employers face a real opportunity: They can find better ways to tap the talents of women who will commit to hard work and responsibility but cannot put in over-long days.     

Understanding Local Food Consumers: Theory of Planned Behavior and Segmentation Approach

Purpose: The objectives of this study were to examine the antecedents and consequence of consumer attitudes toward local food and to segment these consumers using their food-related lifestyle (FRL) attributes. Using the Theory of Planned Behavior, we proposed three factors to impact attitude toward local food (health consciousness, concern for the environment, and concern for local economies) along with subjective norm and perceived behavioral control to influence intentions to purchase local food.

Methodology: Data were collected from 502 local food consumers measuring the following: antecedents and consequence of attitude toward local food; FRL; demographic information.

Findings: Health consciousness, concern for the environment, and concern for local economies were found to be significant predictors of attitude toward local food. Attitude toward local food and subjective norm, but not perceived behavioral control, were found to have a significant effect on intention to purchase local food. Further, segmenting based on their FRL yielded four types of consumers (Impromptu Novelty Explorer, Uninvolved Connoisseur, Involved Information Seeker, and Apathetic Local Food Consumer). An ANOVA provided a snapshot of several demographic and psychographic differences between segments.     

Branded product information search on the Web: The role of brand trust and credibility of online information sources

Drawing upon the cost–benefit framework and trust mechanism as a risk reducer, this study examines the influence of brand factors and source credibility on branded product information Web searches. The online survey was conducted within the pre-purchase context of digital camera brands. The results revealed that brand factors did not influence overall branded information search efforts. However, brand trust and source credibility appeared to influence the different types of online information sources sought.     

Bayesian exploratory factor analysis

This paper develops and applies a Bayesian approach to Exploratory Factor Analysis that improves on ad hoc classical approaches. Our framework relies on dedicated factor models and simultaneously determines the number of factors, the allocation of each measurement to a unique factor, and the corresponding factor loadings. Classical identification criteria are applied and integrated into our Bayesian procedure to generate models that are stable and clearly interpretable. A Monte Carlo study confirms the validity of the approach. The method is used to produce interpretable low dimensional aggregates from a high dimensional set of psychological measurements.

Stopping the exodus of women in science

A new study reveals that U.S. companies face a troubling brain drain: Fifty-two percent of female scientists, engineers, and technologists abandon their chosen professions. If companies understand why women drop out, however, they can create targeted interventions and head off a talent shortage.
