Theories of political redistribution are tested using data collected in three phases of the International Social Survey Programme. Individuals categorized as having high, middle, or low incomes were asked whether they consider the overall tax burden in their countries too high, too low or about right. Very few citizens indicated that they were satisfied with tax systems; most believed that taxes on low and middle incomes are too high, while taxes on high incomes are too low. Support for tax systems is bimodal within the income classes, with the richest 5% being the most supportive, and the median in a population being second. Ideological values have a strong impact on political support for redistribution across all income classes. The results bear witness to the multidimensional nature of preferences for redistribution, and to the delicate question of the effectiveness of democracy in implementing citizens' preferences. 相似文献

Si studia una nozione di riassunto esaustivo, che diremo a fini predittivi e che è già stata oggetto d'indagine da parte di F. Spizzichino sotto diversa denominazione. Si pone in evidenza la naturalezza di questa nuova definizione che, senza alcuna restrizione, può essere applicata in ogni tipo di ragionamento induttivo. Nella prima parte della ricerca, dopo alcune esemplificazioni sull'applicazione in alcuni tipici problemi inferenziali con particolare riguardo alla costruzione di modelli ipotetici a partire da considerazioni squisitamente predittive del concentto di riassunto esaustivo a fini predittivi, se ne studiano le principali proprietà. Nella seconda parte (che apparirà in un prossimo numero di questa Rivista) se ne analizzeranno i rapporti con le più abituali nozioni di riassunto esaustivo.

In this paper (first part of a wider work; the second part will appear in the next issue of this journal) we support the idea that the major objective of inductive reasoning is the distribution for outcomes of any sample not jet observed (predictive distribution) Parameters are a secondary device that can ultimately be justified and can lend some simplification.According to this point of view, we study a notion of prediction sufficiency introduced by F. Spizzichino (1978). Many of the results true for classical sufficient statistics apply to our predictive sufficient statistics as we demonstrate in Section 3.In the second part we analyse sequences of predictive sufficient statistics and their relations with classical sufficient statistics for the parameters which are limits of these sequences. The examples of Section 2 represent a first limited approach to this problem.

Factor Saving Innovation 总被引:1,自引:0,他引:1

It has been argued that concave models exhibit less “endogeneity of growth” than models with increasing returns to scale. Here we study a simple model of factor saving technological improvement in a concave framework. Capital can be used either to reproduce itself, or, at some additional cost, to produce a higher quality of capital, which requires less labor input. If better quality capital can be produced quickly, we get a model of exogenous balanced growth as a special case of ours. If, however, better quality capital can be produced slowly, we get a model of “endogenous growth” in which the growth rate of the economy and the rate of adoption of new technologies is determined by preferences, technology and initial conditions. Moreover, in the latter case, the process of growth is necessarily uneven, exhibiting a natural cycle with alternating periods of high and slow growth. Growth paths and technological innovations also exhibit dependence upon initial conditions. The model provides a step toward a theory of endogenous innovation under conditions of perfect competition.

The rationale of ecolabelling is to enable firms to reap the willingness-to-payfor the environmental attributes of goods by helping consumers toidentify ``green' products. By so doing, ecolabelling is expected tostimulate spontaneous environmental innovation and to reduce aggregatedpollution. Our analysis however outlines situations under whichecolabelling could induce perverse effects, namely increased investment inconventional technologies before the labels are awarded, and examineswhether restricting the issue of labels could constitute an antidote. 相似文献

Interbank markets allow credit institutions to exchange capital for purposes of liquidity management. These markets are among the most liquid markets in the financial system. However, liquidity of interbank markets dropped during the 2007–2008 financial crisis, and such a lack of liquidity influenced the entire economic system. In this paper, we analyse transaction data from the e-MID market which is the only electronic interbank market in the Euro Area and US, over a period of 11 years (1999–2009). We adapt a method developed to detect statistically validated links in a network, in order to reveal preferential trading in a directed network. Preferential trading between banks is detected by comparing empirically observed trading relationships with a null hypothesis that assumes random trading among banks doing a heterogeneous number of transactions. Preferential trading patterns are revealed at time windows of 3-maintenance periods. We show that preferential trading is observed throughout the whole period of analysis and that the number of preferential trading links does not show any significant trend in time, in spite of a decreasing trend in the number of pairs of banks making transactions. We observe that preferential trading connections typically involve large trading volumes. During the crisis, we also observe that transactions occurring between banks with a preferential connection occur at larger interest rates than the complement set—an effect that is not observed before the crisis. 相似文献
