Given that the use of Likert scales is increasingly common in the field of social research it is necessary to determine which
methodology is the most suitable for analysing the data obtained; although, given the categorization of these scales, the
results should be treated as ordinal data it is often the case that they are analysed using techniques designed for cardinal
measures. One of the most widely used techniques for studying the construct validity of data is factor analysis, whether exploratory
or confirmatory, and this method uses correlation matrices (generally Pearson) to obtain factor solutions. In this context,
and by means of simulation studies, we aim to illustrate the advantages of using polychoric rather than Pearson correlations,
taking into account that the latter require quantitative variables measured in intervals, and that the relationship between
these variables has to be monotonic. The results show that the solutions obtained using polychoric correlations provide a
more accurate reproduction of the measurement model used to generate the data. 相似文献

The economic literature on cost‐effectiveness analysis in the context of decisions by health technology assessment agencies assumes as the quantity of interest a linear combination of the mean of the sampling distribution of the effectiveness and the cost. We argue that this is not always reasonable. Our reasons for this assertion are that (i) treatments are compared on the basis of mean values, and for some useful models the mean of the distribution of the cost, which is conditional on the available data, does not exist, and (ii) even for models for which the mean does exist, it might not constitute an accurate reflection of the distribution. This paper presents a general Bayesian cost‐effectiveness analysis of a single treatment, where the quantity of interest is the distribution, conditional on the data, of the net benefit. This approach permits a natural extension to several treatments, which enables us to make a statistical comparison. Illustrations with treatment comparisons for real and simulated data are given. 相似文献

This study analyses IASB's stipulations on fair value usage in its standard designed for SMEs and the reactions of national standard setters, preparers and users of financial reporting in this respect. It tries to clarify fair value applications such as market value and value in use and the appropriateness of their usage for the case on hand. This research determines the inconsistencies within IASB ED IFRSfor SMEs (2007) related to the usage of fair value, underlined by the respondents' comment letters. The content analysis of all the above, conducted according to the type of economy and nature of respondent, along with the statistical techniques applied, indicates a partial approval of fair value usage under the following conditions: clarification of the concept, details on its usage in relation to market liquidity and the nature of the asset, additional guidance regarding the measurement methods. We advocate for the value in use, an application of the fair value based on internal valuations, which offers an adequate cost-benefit rate. The final version ofIFRSfor SMEs highlights both the preference of market information over the internal valuations and the insufficient information regarding solutions suited for non-liquid markets. It may be appropriate for the IASB, maybe in collaboration with the IVSC, to provide guidance and details regarding the implementation and disclosure of the valuation techniques applicable to this type of entities. 相似文献

We analyze the evolution of culture when parents socialize children to the cultural variants that maximize child lifetime utility. Parents invest in cultural transmission by taking into account that children are also influenced by peers. We model the influence of peers by assuming that children observe different cultural variants in their peer group, assign merit to them and adopt one variant, following a probabilistic adoption rule. We show that cultural diversity is sustainable even if all parents strive to transmit the same variant. We also show that a parental demand for cultural pluralism does not guarantee cultural diversity. 相似文献

This paper studies the trade balance dynamics in the G-7 countries plus Spain. We estimate a SVAR model to identify three
different shocks: real supply shocks, real demand disturbances and nominal shocks. A microfounded stochastic open-economy
model is built to derive the long-term identification restrictions. Estimates show that real demand shocks explain most of
the variability of trade imbalances, whereas, contrary to previous findings, nominal shocks play a very limited role. These
results are consistent with the predictions of a widely set of open-economy models and illustrate that demand policies are
the main responsible of trade imbalances. 相似文献

We investigate how North–South integration affects the location of foreign direct investment (FDI) between the two regions. The theoretical analysis suggests that integration affects the incentives of partner and nonpartner Northern countries to locate in the South differently and may lead to investment diversion from the Northern partner. We test our propositions using data from the North American Free Trade Agreement (NAFTA), the first major North–South integration scheme. We find that NAFTA partner FDI in Mexico has increased since the inception of NAFTA above what is implied by other determinants of FDI and the global upward trend during this time. Other countries have not increased their use of Mexico as an export platform. We also find no evidence that inward US FDI has been diverted. The results are robust to a number of different model and econometric specifications as well as the skill data used. 相似文献

This paper contributes to the airport benchmarking literature in two ways. To our knowledge, this is the first attempt at using a stochastic distance function to measure airports’ productivity changes while considering multiple outputs. Secondly, we calculate the evolution and decomposition of the Total Factor Productivity (TFP) for Spanish airports. The average rate of productivity showed a slight annual improvement of 0.9%, and the core engine of this was 3% increase in technical progress rather than through efficiency. Results, by airport, identify those needing improvement, to be more attractive in the Spanish airport restructuring program. 相似文献

This article introduce two new characteristics of firms, which are important, from a macroeconomic view, to evaluate the roll
of entrepreneurial tissue in the territorial economic growth: functional dependence and productive dependence. An empirical
analysis has been formulated in order to contrast the importance of these entrepreneurial characteristics, and try to show
its relation with territorial economic growth. 相似文献

In this paper, we analyze a model of repeated strategic communication between a sender and a receiver. The sender has private information on a policy‐relevant variable but does not know the receiver's motives. Together with the desire of the sender to please the receiver and the desire of the receiver to be pleased, the two‐sided incomplete information creates an interesting communication problem in which players can choose to use information strategically. We analyze various modes of communication, which allow for information transmission, and we compare them in terms of both the quality of the policy implemented and the welfare of the players. 相似文献
