AbstractAim: This study aimed to assess patients’ preferences for HIV treatment in an urban Colombian population.Methods: A Discrete Choice Experiment (DCE) was conducted. Urban Colombian HIV patients were asked to repetitively choose between two hypothetical treatments that differ in regard to five attributes ‘effect on life expectancy’, ‘effect on physical activity’, ‘risk of moderate side effects, ‘accessibility to clinic’ and ‘economic cost to access controls’. Twelve choice sets were made using an efficient design. A Mixed Logit Panel Model was used for the analysis and subgroup analyses were performed according to age, gender, education level and sexual preference.Results: A total of 224 HIV patients were included. All attributes were significant, indicating that there were differences between at least two levels of each attribute. Patients preferred to be able to perform all physical activity without difficulty, to have large positive effects on life expectancy, to travel less than 2?h, to have lower risk of side-effects and to have subsidized travel costs. The attributes ‘effect on physical activity’ and ‘effects on life expectancy’ were deemed the most important. Sub-analyses showed that higher educated patients placed more importance on the large positive effects of HIV treatment, and a more negative preference for subsidized travel cost (5% level).Limitations: A potential limitation is selection bias as it is difficult to make a systematic urban/rural division of respondents. Additional, questionnaires were partly administered in the waiting rooms, which potentially led to some noise in the data.Conclusions: Findings suggests that short-term efficacy (i.e. effect on physical activity) and long-term efficacy (i.e. effect on life expectancy) are the most important treatment characteristics for HIV urban patients in Colombia. Preference data could provide relevant information for clinical and policy decision-making to optimize HIV care. 相似文献

This article estimates the impact of low-cost airlines on Spanish tourism during the first decade of the 21st century looking tourist traffic from the principal EU-15 member states using a dynamic panel data. The expansion in low-cost airline activity has had significant, positive direct and indirect effects on the Spanish economy. The study also looks at some of the key elasticities of demand that have influenced this. 相似文献

While mobility's effect on knowledge transfer to firms that hire mobile employees is well demonstrated, we choose to explore mobility's effect on knowledge transfer to firms that lose these employees. Focusing on this ‘outbound mobility’ allows us to isolate effects of social mechanisms associated with mobility. We find that semiconductor firms losing employees are more likely to subsequently cite patents of firms hiring these employees, suggesting that mobility‐driven knowledge flows are bidirectional. In addition, the outbound mobility effect is pronounced when mobility occurs between geographically distant firms, but attenuates for geographically proximate firms since other redundant knowledge channels exist within regions.

We analyse the concept of causality in the social sciences, whose development is insufficient and lesser than the methodology
developed for its study. The nature of the causal process as the production of effects remains unclear and the relationships
considered to be manifestations of that process cannot be taken for proof of its existence. Given these difficulties, we suggest
that, aside from the inherited interpretations, the practice of the concept of causality makes reference to correctly specified
relationships not confounded by others; characteristics identical to those which define validity. In that way, causality is
equivalent to the validity of a relationship. Beyond merely re-understanding causality, this proposal permits the deduction
that the temporal precedence of the cause is a necessary condition only for one type of causality, making it possible to consider
other types, not admitted by the traditional notion, in which the cause is consequent or simultaneous to the variable to be
explained. Examples and characteristics of these types of causality are presented and considered to be useful for the social
sciences. 相似文献

Celebrity endorsement has become a very popular communication strategy in the nonprofit sector, although there are still doubts about its effectiveness. Specifically, one interesting question is whether the involvement of individuals with a social cause can explain differences in the valuation and effects of the celebrity endorsement strategy in consumer behavior. Taking into account this fact, the current research presents a causal model that analyzes the determinants of the attitude toward ads involving celebrities and the explanatory variables of the behavioral intentions in this sector. We worked with two subsamples of individuals with high and low involvement, who rated a fictitious ad with a well-known social entity and a celebrity. As a result, we observed that the strategy can influence the group of low involved people and have no significant effects on the segment with high involvement. 相似文献

This study aims to analyse the small business sector in Spain for institutional care. In the Autonomous Region of Valencia, this sector is represented by non‐profit institutions. Our results show that non‐profit centres easily fulfil the legal requirements, especially with regard to personnel. They are generally of high quality and receive a large amount of volunteer work and funds from donators. Small business centres show an accurate daily cost per user of up to €56.48, a substantially lower rate than those offered by large centres. 相似文献

Recent changes in deregulation and technology have made banking one of the most competitive sectors in the global economy. Within this background, corporate image management has gained importance as a way of differentiating companies. This paper aims to develop a scale to analyse the corporate image in banking. Derived from a review of the literature, a scale with the most cited dimensions of analysis is developed. This scale is then tested by means of an empirical study of 450 individuals, where dimensionality, reliability and validity requirements are confirmed. Both theoretical and managerial implications are presented. 相似文献

The main aim of this paper is to investigate about the effect that a measure of the process innovation performance of a firm has on its labour productivity growth. This analysis is mainly a consequence of two considerations. The first one results from a clear differentiation of the role that product and process innovations have on a firm's performance. The second one is to assume that the knowledge capital of a firm is mainly composed by its successful research. The study demonstrates that process innovation has a positive and significant effect on firm's productivity growth. Moreover, this result is robust under a wide range of alternative specifications and, in any case, the variable behaves much better than R&D intensity. Following previous research, the detected quadratic relationship between vertical product differentiation and process innovation performance leads to the existence of some firms for which there exist a trade–off between quality and productivity. 相似文献

This article checks for the adequacy of using GARCH models in exchange rate series. Using the Hinich portmanteau bicorrelation test, we find that a GARCH formulation or any of its variants fails to capture the data generating process of the main Latin American exchange rates. Our results highlight the potential of having misleading public policy when estimates are based in GARCH types of models. This article also complements recent similar findings encountered in European and Asian economies. 相似文献

We present a new measure of legal protection of minority shareholders against expropriation by corporate insiders: the anti-self-dealing index. Assembled with the help of Lex Mundi law firms, the index is calculated for 72 countries based on legal rules prevailing in 2003, and focuses on private enforcement mechanisms, such as disclosure, approval, and litigation, that govern a specific self-dealing transaction. This theoretically grounded index predicts a variety of stock market outcomes, and generally works better than the previously introduced index of anti-director rights. 相似文献
