We provide a test of the impact of voters' political ideology on economic growth and of the role of preferences for government size as a transmission channel. We focus on France from the beginning of its stable democratic experience in 1871. A move of voters' ideology to the right increases economic growth over the total observation period. However, the growth effect of ideology is mediated by voters' preferences for government size only during the post‐World War II period. For reverse causality concerns, we use the political ideology of other historical democracies as an instrument variable for France's ideology. (JEL E6, O43, H11) 相似文献

Les auteurs examinent l'évolution des tâches accomplies par les travailleurs au Royaume‐Uni entre 1997 et 2006, qu'elle soit due à une reconfiguration des professions elles‐mêmes (marge intensive) ou à une variation de leur part respective dans l'emploi (marge extensive). Ils se fondent notamment dans cet examen sur des données de la Skills Survey, enquête britannique sur les compétences. Leur analyse montre que la variation à la marge intensive est notable et aussi importante que la variation à la marge extensive. Une analyse économétrique fait ressortir en outre que le progrès technique joue un rôle dans l'évolution à la marge intensive, mais pas les délocalisations. 相似文献

The US National Academy of Sciences (NAS) recently published voluntary guidelines for human embryonic stem (hES) cell research. The NAS guidelines propose two levels of oversight. At the local level, research institutions are to create Embryonic Stem Cell Research Oversight (ESCRO) committees with a mandate to assess the scientific merit and ethical acceptability of hES cell research. At the national level, a new committee is to be created, not to review specific research proposals, but rather to periodically assess, and as needed revise, the NAS guidelines. In this article, we critically assess this proposal. In particular, we review the benefits and limitations of local research review. On this basis, we argue that local review is insufficient for hES cell research and that while there are obvious pragmatic and political reasons for the NAS to favor local research review, there are more compelling reasons for the NAS to have recommended national review of hES cell research proposals. 相似文献

Ranked set sampling (RSS) is an advanced sampling method which is very effective for estimating mean of the population when exact measurement of observation is difficult and/or expensive. Balanced Groups RSS (BGRSS) is one of the modification of RSS where only the lowest, the median and the largest ranked units are taken into account. Although BGRSS is advantageous and useful for some specific cases, it has strict restrictions regarding the set size which could be problematic for sampling plans. In this study, we make an improvement on BGRSS and propose a new design called Partial Groups RSS which offers a more flexible sampling plan providing the independence of the set size and sample size. Partial Groups RSS also has a cost advantage over BGRSS. We construct a Monte Carlo simulation study comparing the performance of the mean estimators of the proposed sampling design and BGRSS according to their sampling costs and mean squared errors for various type of distributions. In addition, we give a biometric data application for investigating the efficiency of Partial Groups RSS in real life applications. 相似文献

This paper introduces a new notion of consistency for social choice functions, called self‐selectivity, which requires that a social choice function employed by a society to make a choice from a given alternative set it faces should choose itself from among other rival such functions when it is employed by the society to make this latter choice as well. A unanimous neutral social choice function turns out to be universally self‐selective if and only if it is Paretian and satisfies independence of irrelevant alternatives. The neutralunanimous social choice functions whose domains consist of linear order profiles on nonempty sets of any finite cardinality induce a class of social welfare functions that inherit Paretianism and independence of irrelevant alternatives in case the social choice function with which one starts is universally self‐selective. Thus, a unanimous and neutral social choice function is universally self‐selective if and only if it is dictatorial. Moreover, universal self‐selectivity for such functions is equivalent to the conjunction of strategy‐proofness and independence of irrelevant alternatives or the conjunction of monotonicity and independence of irrelevant alternatives again. 相似文献

Parametric modelling run by the explicitly defined algorithms generating synchronically auditable dynamic forms and patterns, has become a prominent method especially in architecture. Though the use of parametric models has got wider in urban design, the critical reflection on the actual and possible application of the method in urbanism has fallen limited so far. The paper tends to relate parametric design with the contemporary understanding of urbanism with regards to the idea of design control in the the context of complexity. From this perspective, the actual performance of the model application in urban context is discussed with the renowned project of Kartal-Pendik Masterplan (Zaha Hadid Architects) in Istanbul, Turkey. 相似文献

A direct parametric test is proposed to detect monotonic and non-monotonic types of heteroscedasticity. After giving brief information about non-monotonic types of heteroscedasticity, the test algorithm is introduced. Proposed test and usual heteroscedasticity tests are compared on monotonic and non-monotonic types of heteroscedasticity in real and artificial data. 相似文献
