As recent studies in different countries show, tax data offer the opportunity to estimate income or wealth shares for the upper income groups. However, several critical points must be considered in order to avoid misleading conclusions: the interpolation technique used, legal amendments, and tax fraud. In this note we take Spanish wealth tax as a case study to assess the importance of these factors, and compare our results with those obtained by Alvaredo and Saez (2009 ). Although the results of the two analyses are very similar, our approach complements theirs by offering a more precise treatment of the correction of fiscal underassessment and tax fraud in real estate, which is the main asset in Spaniards' portfolios.  相似文献

Using administrative records of births from the Perinatal Surveillance System of the Peruvian Social Security System (ESSALUD), we test whether high admissions of pregnant women affected non-elective caesarean section (C-section) rates in the ESSALUD public hospitals during 2005–2006. We present a basic theoretical model that considers physician preferences for leisure and hospital capacity constraints, and test the model predictions. We find that physician demand for leisure increases the probability of C-sections in small and medium-size hospitals, while hospital capacity constraints set a limit on them. We discuss the policy implications as well as the policies implemented to avoid unnecessary C-sections.  相似文献

This paper analyses the impact of factors related to innovation and the environment, among others, on labour productivity in the Spanish transport sector. The methodological approach used in this study was based on the CDM structural model. The main advantage of this model is its capacity to integrate investment in R&D and the generation of knowledge and production innovation. The data used in the estimations were obtained from the Technological Innovation Panel (PITEC) database. PITEC is a panel-type database jointly prepared by the Spanish National Institute of Statistics (INE) and the Spanish Foundation for Science and Technology (FECYT). The econometric results show that reducing the environmental impact has a statistically significant and positive effect at all stages of the innovative process and above all on labour productivity of transport firms, where the improvement of labour productivity can reach 8.35% compared to non-ecoinnovative companies. This finding could alert firms in the transport sector to the need to improve their activities by adopting environmentally proactive attitudes.  相似文献

This study analyses the impact which recessionary conditions have had in Chile on a particularly vulnerable age group: children and the young. In addition to the external crisis, Chile experienced serious imbalances in the form of inflation and balance-of-payments deficits in the early 1970s. Social development experts have long recommended the application of selective policies to ‘target groups’ whose situation is especially vulnerable to economic fluctuations. During the early 1970s, Chile implemented policies specifically designed to improve the situation of children, especially in terms of mother and child care, and programmes were undertaken to combat infant undernutrition. This paper evaluates the success of these programmes in counteracting the negative effects of the recession and the recessionary adjustment policies.  相似文献

Cross-country panel data are used to assess the effect of free-tradeagreements on flows of foreign direct investment (FDI). Free-tradeagreements are found to have a significant positive effect onFDI flows, and free-trade agreements are found to matter morefor the smaller members of the agreement. For example, the NorthAmerican Free-Trade Agreement’s (NAFTA) effect on FDIflows into Mexico is much larger than its effect on flows intothe United States. These cross-country results are used to assessNAFTA’s effect on FDI flows into Mexico. After controllingfor a set of other factors—such as an increase in worldwideFDI flows—the trade agreement is found to generate FDIflows nearly 60 percent higher than they would have been withoutthe agreement.  相似文献

Microeconomic public transport models aimed at maximizing social benefits usually consider demand in an aggregate manner. In this paper we examine the effect of this approach on the optimal values of frequency and vehicle size by comparison with models where demand is described in detail as a matrix of flows between every station in a single line service. The theoretical analysis and the numerical examples suggest that the spatially aggregated model underestimates optimal frequency and overestimates vehicle size.  相似文献

In this article, we contribute to the understanding of the role that external risk perceptions play in decisions regarding the combination of company-owned and franchised units in the hospitality industry, and to knowledge of the impact of specific CEO characteristics on perceptions of environmental uncertainty. We examine the effects of tenure, an entrepreneurial nature and the innovative attitude of the CEO on the perception of external risk, and address the direct and indirect consequences of such perceptions of external risk on the configuration of the network of outlets. Our results show a significant relationship between the characteristics of the CEO and the perception of risk but, contrary to expectations, risk perception is associated with a lower degree of franchised outlets within the ownership mix.  相似文献

20世纪40年代起,拉美国家采取的是以贸易保护思想为基础的进口替代政策,70年代中期开始,大部分拉美国家开始了以贸易开放、资本开放为核心的“新自由主义改革”。本文首先对拉美对外贸易政策的沿革进行回顾,就拉美的“新自由主义”改革的实效进行了一个基本考察,在此基础上,通过计量模型详细探讨了拉美国家的出口和经济增长的关系。  相似文献
