The principal aim of this paper is to evaluate the impact of the future European high-speed train network on accessibility, by reducing time distance between places and modifying their relative location. We compare the current situation with that foreseen for the year 2010, according to the Outline Plan of the European High-Speed Train Network, in order to analyse which areas will most benefit from construction and improvement of the infrastructure. It is hypothesized that the high-speed train will certainly bring the peripheral regions closer to the central ones, but will also increase imbalances between the main cities and their hinterlands. A weighted average distance indicator is applied for this purpose. This measure identifies the spatial distribution of accessibility in the area of study, emphasizing the infrastructure effects, and locates accessibility changes at the European level. A Geographic Information System (GIS) has been used to carry out this study. 相似文献

Cet article examine les différentes politiques économiques susceptibles d'avoir des répercussions sur l'économie sociale en tant que secteur institutionnel.En premier lieu il présente un cadre d'analyse permettant d'appréhender les contenus des politiques et en offre trois typologies.A la lumière de ce cadre dans unpremier temps il fait unbilan global des politiques mises en oeuvre en Europe pour se centrer dans un deuxième temps sur l'Espagne l'un des pays de l'Union où le niveau de développement de ces politiques est le plus avancé .Pour terminer, l'auteur évalue l'efficacité des principales mesures de politique économique mises en oeuvre dans ce pays.
The article considers different economic policies likely to affect the social economy sector as an institutional sector. In a first time it sets up an analytical framework which allows to apprehend the policies contents and offers three typologies. In the light of this framework it first makes a global evaluation of policies implemented in Europe and then focuses on Spain, one of the Union countries with the highest level of development of these policies. Finally, the author evaluates the efficiency of the main measures of economic policy applied in this country. 相似文献

The aim of this paper is to provide a connection between concentration and inequality. In particular, we show that the general
entropy inequality indices are, among inequality measures, those consistent with the whole set of Hannah-Kay concentration
indices. We isolate the inequality component underlying concentration measures, obtaining an explicit additive decomposition
of the change in concentration into the change in its two components, i.e., inequality and the number of firms. This relationship
proves to be valid for the whole set of Hannah-Kay concentration indices, and embodies as particular cases some others previously
found in the literature.
We are particularly grateful to Emilio Cerdá for helpful comments on the mathematical formulation of the paper. The second

We provide a partial ordering view of horizontal inequity (HI), based on the Lorenz criterion, associated with different post‐tax income distributions and a (bistochastic) non‐parametric estimated benchmark distribution. As a consequence, several measures consistent with the Lorenz criterion can be rationalized. In addition, we establish the so‐called HI transfer principle, which imposes a normative minimum requirement that any HI measure must satisfy. Our proposed HI ordering is consistent with this principle. Moreover, we adopt a cardinal view to decompose the total effect of a tax system into a welfare gain caused by HI‐free income redistribution and a welfare loss caused by HI, without any additive decomposable restriction on the indices. Hence, more robust tests can be applied. Other decompositions in the literature are seen as particular cases. 相似文献

通过对美国和欧洲共10个国家(英国、法国、德国、意大利、西班牙、丹麦、荷兰、奥地利、波兰)的16,000名成年人进行的跨国调查(2002及2003年),本文考察了当地的宗教信仰状况,着重于他们对神权、生命的实质及生命的开始等三方面的理解认识,并进一步研究了他们的一些宗教行为(如祈祷及参与宗教活动的频率)和对宗教领袖的信任程度。本文的重点在于分析个人宗教价值观对其就新兴生化科技所持政治态度的影响。为此收集了广泛的研究数据,考察受访者对主要生化科技,如胚胎干细胞应用、转基因食品和克隆等的观点和态度。最后,使用多元回归研究模式的结构方程模型(SEM)分别描述了人们的宗教价值观、对生命的理解、年龄、性别和教育水平等几个变量对于堕胎、胚胎干细胞应用研究和安乐死等三项公共政策争论的影响。 相似文献

This paper deals with the specification of pollution abatement in dynamic computable general equilibrium (CGE) models and analyses the dynamic feedback mechanisms between economy and abatement in the context of environmental policy. A Ramsey-type economic model is presented, in which bottom-up technical and economic information on abatement techniques is integrated in a top-down dynamic CGE context. The practical suitability of the specification is illustrated by an empirical application for climate change and acidification in the Netherlands. The results show that a mixture of some slowdown of economic growth, a substantial restructuring of the economy and implementation of most technical abatement measures is optimal. 相似文献

Threshold cointegration and nonlinear adjustment between goods and services inflation in the United States 总被引:1,自引:0,他引:1
Vicente Esteve Salvador Gil-Pareja Jos Antonio Martínez-Serrano Rafael Llorca-Vivero 《Economic Modelling》2006,23(6):1033-1039
In this paper, we model the long-run relationship between goods and services inflation for the United States over the period 1968:1–2003:3. Our empirical methodology makes use of recent developments on threshold cointegration that consider the possibility of a nonlinear relationship between the two inflation series. According to our results, the null hypothesis of linear cointegration would be rejected in favor of a two-regime threshold cointegration model. Consequently, we could expect a cointegrating relationship only when the divergence between services inflation and goods inflation is above the threshold point estimate. 相似文献

In the EURURALIS project, a chain of models was used to predict the changes in sustainable development indicators for European human well-being, ecology and economy issues, for four alternative scenarios of the future socio-economic development. This paper describes the biodiversity analysis of the project. Models based on general relationships between environmental factors and biodiversity loss were combined with socio-economic, land-use and environmental models to derive data that were integrated into an interactive tool for policy makers. The biodiversity analysis takes into account the effects of land-use change, climate change, fragmentation by major roads, area of unfragmented patches, nitrogen deposition, forestry and disturbance. Results show that biodiversity is projected to decrease between now and 2030 in most countries for all scenarios, indicating that it is unlikely that the EU will be able to fulfill its commitment to stop biodiversity loss by 2010. This is mainly due to urbanization and increase in stress factors, and outweighs the area increase of nature arising from land abandonment. Merits, limitations and uncertainties of this approach to biodiversity assessment are discussed. 相似文献

Do Institutions Cause Growth? 总被引:11,自引:5,他引:11
Edward L. Glaeser Rafael La Porta Florencio Lopez-de-Silanes Andrei Shleifer 《Journal of Economic Growth》2004,9(3):271-303
We revisit the debate over whether political institutions cause economic growth, or whether, alternatively, growth and human capital accumulation lead to institutional improvement. We find that most indicators of institutional quality used to establish the proposition that institutions cause growth are constructed to be conceptually unsuitable for that purpose. We also find that some of the instrumental variable techniques used in the literature are flawed. Basic OLS results, as well as a variety of additional evidence, suggest that (a) human capital is a more basic source of growth than are the institutions, (b) poor countries get out of poverty through good policies, often pursued by dictators, and (c) subsequently improve their political institutions. 相似文献

It is generally acknowledged that the growth rate of output, the seasonal pattern, and the business cycle are best estimated
simultaneously. To achieve this, we develop an unobserved component time series model for seasonally unadjusted US GDP. Our
model incorporates a Markov switching regime to produce periods of expansion and recession, both of which are characterized
by different underlying growth rates. Although both growth rates are time-varying, they are assumed to be cointegrated. The
analysis is Bayesian, which fully accounts for all sources of uncertainty. Comparison with results from a similar model for
seasonally adjusted data indicates that the seasonal adjustment of the data significantly alters several aspects of the full
model.
