We propose a simple checklist for the users of policy supporting research in order to decide whether a piece of research begs further study or can be dismissed right away. The checklist focusses on the quality of the research question (is it a research question, and is the research question answerable); the kind of knowledge along with the order, level and quality of data needed for answering the RQ; the methods of analysis used; the degree to which the research results support the conclusions; and whether the conclusions provide an answer to the research question. 相似文献

The present paper outlines a study based on an experimental design that investigated the effect of online price discounts and free gifts on consumers’ evaluation of the brand, in the context of an airline. The study also analyzed whether promotion-proneness exercises a moderating effect on this relationship. It was found that discounts generate a more positive brand image than free gifts among promotion-prone users, while for less promotion-prone individuals, the opposite is true. The results will help managers to select the most appropriate online sales promotion type for reaching different consumer groups, depending on their promotion-proneness, in line with the needs and objectives of the service firm. 相似文献

The spatial survival models typically impose frailties, which characterize unobserved heterogeneity, to be spatially correlated. However, the spatial effect may not only exist in the unobserved errors, but it can also be present in the baseline hazards and the dependent variables. A new spatial survival model with these three possible spatial correlation structures is explored and used to investigate the implementation of value‐added tax (VAT) in 99 countries over the period 1970–2009. Estimation is performed by a Bayesian approach through the Markov chain Monte Carlo method. The estimation results suggest the presence of a significant spatial correlation among the VAT introductions of neighbouring countries. 相似文献

The long-term growth in the air transport is leading to the need to expand airport infrastructure but this has serious environmental implications. Thus, there is the need to establish an alternative to the traditional airport pricing structure for landing fees, which reflects the overall costs that air transport operators impose on others. Airport pricing should provide a sound guide for future investments, and at the same time reflect whether additional facilities are needed and at what price, by taking into account all costs, including environmental costs. This paper analyses one application of Ramsey Pricing on uncongested Spanish airport, by considering the CO2 emission costs as a valuable input. 相似文献

This paper studies how promotion tournaments motivate workers to accumulate human capital when wages are constrained by outside labor markets. Patient firms can retain some control over tournament prizes through a relational contract, but if the firms are competitive, full efficiency does not obtain in equilibrium even for discount factors arbitrarily close to one. Full efficiency, however, may be feasible in firms with superior technologies; thus, technological efficiency breeds incentive efficiency. The paper also shows that a wage floor leads to insufficient human capital investment in competitive firms, but could lead to excessive investment in technologically superior firms. 相似文献

This article evaluates how bus users perceive the quality of their public transport service. In particular it looks at how perception of quality varies according to the available information. The experiment compares an overall evaluation of service quality before and after making passengers reflect on the importance of certain fundamental system variables which they may not have previously considered.Focus groups were used to individualise the most relevant variables. A quality survey was carried out both on-board buses and at bus stops and the overall service quality was related to the aforementioned variables using ordered probit models. The perception of quality is shown to change with the category of user and that there tends to be more criticism towards variations in overall quality until the users are stimulated into thinking more deeply about other influential variables. The application of this methodology may provide operating companies with valuable information for planning marketing policies aimed at different categories of user, in order to improve the service quality and attract more passengers to using public transport. 相似文献

The aim of this paper is to review the usefulness of the software CAQDAS QSR—Nvivo-6 in a PhD. Thesis, which consisted of
finding the long-term psychological effects of experiences of imprisonment and torture for political reasons in their Chilean
survivors. For this research, it was created and administered an in-depth interview to 60 survivors, from which outcome was
9900 paragraphs, coded into 784 categories. The software QSR Nvivo-6 threw a report of frequencies, which were compared quantitatively
using Pearson’s χ
2 square test and cluster analysis. We conclude that the software facilitates the development of qualitative thematic content
analysis, simplifying the coding, analysis and display of data. In Addition, it is very useful when working with large quantities
of information, promoting the reliability and validity of studies. However, other aspects are also required to ensure the
rigor of a qualitative study. 相似文献

2011年8月以来,CPI同比涨幅持续回落,全年CPI上涨5.4%。从2012年物价走势看,受政策滞后效应和上年同期基数效应影响,上半年物价有望延续回落趋势,而随着政策微调和宏观经济回升,下半年物价重拾升势的可能性较大。预计2012年全年CPI涨幅为3.6%左右。综合考虑我国工业化发展阶段、刘易斯拐点与资源品价格市场化改革等因素来看,中长期内物价仍存在上涨压力。 相似文献

The evolution of private labels (PLs) can be understood in terms of a strategy adopted by the retail industry with the aim of competing with national brands (NBs). In the 1990s, this strategy led to the development of ‘me too’ products, which currently represent the largest share of store brand products. Since the early 2000s, retailers have widened the range of their store brands by introducing high‐quality products. The aim of this study was to estimate consumers’ attachment to ‘me‐too’ and niche PLs respectively, as compared to NBs. We captured the degree of maturity of these PLs through their price‐elasticities, computed for three staple goods offered by three mass retail companies. It was found that price sensitivity does not differ much between the ‘me‐too’ PLs and the corresponding NBs. This result confirms that ‘me‐too’ products are now considered reliable quality brands. However, in the high quality segment, consumers remain more sensitive to the price of PLs than to that of NBs, a characteristic which may relate to their recent introduction on the market. 相似文献

Benefits and costs associated to hubbing practices of airlines are still subject to much debate. In the previous literature, some standard spatial concentration indices have been proposed to measure it. However, we show that these indices are “ill-defined” because they do not take into account the salient characteristic of hubbing: connecting passengers. The purpose of this research is to present a new methodology which avoids the pitfalls of other methods. Our new methodology also analyzes the level of concentration of the connecting passengers studying two different dimensions: hub airports and routes. Finally, we apply our methodology to some US carriers. 相似文献
