Cases of airline passengers developing deep vein thromboses and contracting infectious diseases during flights have led to airlines' provision of in-flight customer health advice coming under increased scrutiny. By means of a manifest content analysis of the information provided in 50 international airlines’ in-flight magazines, this paper examines the nature and presentation of the health advice that is supplied and comments on the different approaches individual airlines adopt.  相似文献

Freight demand elasticity studies vary significantly in terms of the demand measure, data type, estimation method, commodity type, etc. This wide variation makes it difficult to compare empirical estimates when the differences may arise in part from the methods and data used. In this paper we conduct a comparative analysis to identify systematic sources of influence on direct price elasticity estimates in the context of freight transport, distinguishing between road, rail, and sea transport, using published direct price elasticities from 12 elasticity-derivative studies from five countries. The study focuses on revealed preference elasticities defined by the freight rate for tonnes and tonne kilometres of inter-city freight movements. Systematic sources that explain differences in direct price elasticities include the demand elasticity measure, mode, commodity class, model estimation form, country, and temporal nature of data (e.g., cross-section). Analysts can utilise the model outputs to adjust the empirical evidence from specific studies to control for differences that impact on the behavioural implications of comparative evidence.  相似文献

The Endogenity of the Optimum Currency Area Criteria   总被引:1,自引:0,他引:1  
A country' suitability for entry into a currency union depends on a number of economic conditions. These include, inter alia , the intensity of trade with other potential members of the currency union, and the extent to which domestic business cycles are correlated with those of the other countries. But international trade patterns and international business cycle correlations are endogenous. This paper develops and investigates the relationship between the two phenomena. Using thirty years of data for twenty industrialised countries, we uncover a strong and striking empirical finding: countries with closer trade links tend to have more tightly correlated business cycles.  相似文献

Federal lab commercialization is explored: (1) by analyzing US government patents and (2) in a qualitative analysis of one NASA lab's patents. Tests apply to three distinct sets of patents, 1963–94: NASA, all other US government, and a random sample of all US inventors' patents. The federal patenting rate plummeted in the 1970s. Consistent with increasing commercialization, both NASA's and other federal agencies' rates recovered in the 1980s. The case study finds citations to be a valid but noisy measure of technology spillovers. Excluding 'spurious' cites, two-thirds of cites to patents of NASA-Lewis' Electro-Physics Branch were evaluated as involving spillovers.  相似文献

Union recognition is an ever topical issue. In this article the authors attempt to determine the desirability of instituting and operating a union recognition policy for a small, new enterprise within the manufacturing sector.  相似文献

Goal-setting has become a popular and effective motivational tool, utilized by practitioners and substantiated with decades of empirical research. However, the potential for goal-setting to enhance performance may come at the cost of ethical behavior. I propose a theoretical model linking attributes of goals and goal-setting practices to unethical behavior through two psychological mechanisms – ethical recognition and moral disengagement; and addressing the moderating role of individual differences (e.g., goal-commitment and conscientiousness), as well as the broader organizational ethical context.  相似文献

We investigate jump memory using an extensive database of short‐term S&P 500 index options. Jump memory refers to the attenuation of the implied jump intensity and magnitude parameters following a crash event. We use a genetic algorithm to obtain a time series of implied parameter estimates and posit behavioral and rational explanations for parameter attenuation following a crash event. We find that a nested form of the jump‐diffusion model sharpens the remaining parameter estimates and has a negligible effect on pricing accuracy.  相似文献

  • This study examines the impact of heritage and reputation of nonprofit universities on attitudes of prospective students. Data were collected from 208 community college (preuniversity) students in the USA. Results from structural equations modeling indicate that university heritage positively impacts university reputation, potential students' attitudes, and intentions to pay a tuition premium as well as to recommend the university. Students' nationality moderates the relationships between university heritage, reputation, and attitudes. International students from Asian nations with a long‐term orientation exhibit stronger relationships between these variables than domestic students from the USA. These findings add to the nascent and emerging literature on branding of nonprofit higher education institutions and will be of interest to administrators and marketing managers of universities to nurture and extol their university heritage in student recruitment programs, especially in promotional materials targeting international students.
