Panel data is used to determine the incidence of airport fees on fares in the Spanish leisure market airlines. We also study its structure through an empirical specification of a pricing and demand equation system. The results show the existence of market power, strategic behavior and density economics. We also demonstrate that airlines pass all the airport fees onto customers by increasing fares. Furthermore, we find that the behavior of airlines in routes with the presence of low cost carriers do not differ from other routes. 相似文献

The national health system (NHS) complexity increase requires a review of the managerial human resources evaluation and recruiting methods, considering that nowadays doctors need to improve not just their clinical capabilities, but also managerial competences. At this end it is important to develop performances control models and to identify appropriate results indicators, with the aim of introducing an effective doctors selection system for managerial roles. The paper considers the Italian situation and tests the current evaluation and selection methods, by analysing the literature and the existing legislation and by interviewing experts. Moreover, in order to reach an innovative model, complex organizations have been taken into account as benchmarks. Three different categories of experts have been interviewed and texted: national health care organizations managers, companies managers, and business consultants. The 137 interviewed experts have been asked about four main questions concerning the evaluation for hiring managers as chief medical director, department director, and head of complex units. The conducted research suggests four different options in order to evaluate and to select heads of complex unit for the most strategic roles. By consequence, the analysis shows that required characteristics must be managerial attitudes as well as clinical capabilities. 相似文献

Two facets of leisure, perceived determinants of well-being and enjoyment of common leisure activities, were investigated in 388 participants. For well-being, a principal components (PCA) analysis yielded five components: competence, relatedness and health, wealth, personal values, and freedom of choice. For the enjoyment of leisure activities, another PCA generated seven components: wellness, sedentary leisure, intellectual leisure, social leisure, routine activities, self-realization, and inner peace. Different leisure enjoyment of young adults (18–30 years old) in contrast to adults and seniors was attributed to social transformations as also predicted by several theories of social change. The relationship between the determinants of well-being and enjoyment of leisure activities was statistically significant but meaningfully debatable. 相似文献

This work presents the participation factor and the valuation of a first-generation structured product with European call options on the Eurostoxx, when the uncertainty of the yields is modeled through log-stable processes. The basic statistics of the index yields are also exposed, the α-stable parameters are estimated, and the valuation of the of the structured models is compared through the log-stable and log-Gaussian models using inputs from the bond markets; concluding that investors obtain higher yields than those of the bond market through both models, and that the differences of the yields depend on the participation factor and on the value of the index at the time of liquidation. 相似文献

The item response theory (IRT) also known as latent trait theory, is used for the development, evaluation and administration of standardized measurements; it is widely used in the areas of psychology and education. This theory was developed and expanded for over 50 years and has contributed to the development of measurement scales of latent traits. This paper presents the basic and fundamental concepts of this IRT and a practical example of the construction of scales is proposed to illustrate the feasibility, advantages and validity of IRT through a known measurement, the height. The results obtained with the practical application of IRT confirm its effectiveness in the evaluation of latent traits. 相似文献

This article examines the effect on wages of the Asian-American stereotype as mathematically and technically adept, and the role this stereotype may play in explaining racial wage differences. We propose an empirical strategy to examine the influence of stereotypes on labor market outcomes, with a specific application to the wage premium associated with computer use at work. Using Current Population Survey data, ordinary least squares estimates do not provide compelling evidence that a positive stereotype affects wages for Asian Americans. 相似文献

We provide lab data from four different games that allow us to study whether people have accurate expectations regarding monetary sanctions (punishment/reward) and nonmonetary sanctions (disapproval/approval). Although the strength of the sanction is always predicted with some error (particularly in the case of monetary sanctions), we observe that (i) most subjects anticipate correctly the sign of the average sanction, (ii) expectations covary with sanctions, (iii) the average expectation is very often not significantly different than the average actual sanction, and (iv) the errors exhibit no systematic bias, except in those situations where rewards are frequent. In this line, we find some evidence that punishment is better anticipated than rewards. 相似文献

Group affiliation increases boards' compensation in countries as different as Korea, India, Hong Kong and Italy. In this paper, I examine a 6-year sample of controller-dominated, concentrated-ownership firms in Chile in search of a rationale for these results.I show that, for group-affiliated companies, controllers' presence on the board of directors is associated with a strong negative relation between chair and board compensation and controllers' cash-flow rights. Furthermore, I show that controllers of group-affiliated companies prefer to increase chair and board compensation rather than dividends as their cash-flow rights decrease. 相似文献
