ABSTRACT: The state of disequilibrium which the labour market in Italy (as in all the major industrialised countries) presents, has been the centre of debate in political and economic circles for many years now. How should this disequilibrium be interpreted, considering the complexity of the phenomena found in the labour area? Can they be modeled into global explanatory schemas of general economic theory? The authors believe the complexity of these phenomena can neither be ignored nor simplified, but accepted as a distinguishing feature of the labour market, and thus have to be interpreted on the basis of numerous and often contradictory control variables. This paper hence outlines the principle sources of Italian labour market data available, in order to provide a rational and critical guide to interpreting the available indicators. The sources examined are both institutional (the ISTAT and Ministry of Labour surveys) and private (the employers associations of Confindustria, Assolombarda and Federmec-canica). The paper outlines the areas covered, the methodology, and the qualities and drawbacks that these surveys present. 相似文献

To what extent a taxing authority should be granted the power to impose different tax schedules to different groups of taxpayers? Although the policy maker aims at maximizing social welfare, her tax policy may be distorted by the lobbying activity of taxpayers. In this political environment we characterize the conditions under which social welfare can be increased by restricting the set of tax instruments available to the policy maker; i.e., the scope of tax differentiation. We show that full differentiation is more costly, in terms of welfare distortions, when the lobbies are asymmetric in size, while minimal differentiation is more costly when the tax bases are asymmetric across different groups. 相似文献

Europe's performance with respect to industrial innovation is compared to those of USA and Japan. The reasons for Europe's relatively poor performance are examined and related to institutional, cultural and social factors. An appropriate strategy for innovation in European industry is then defined. 相似文献

This paper deals with the role of reciprocation in the formation of individuals’ social networks. We follow the activity of a panel of bloggers over more than a year and investigate the extent to which initiating a relation brings about its reciprocation. We adapt a standard capital investment model to study how reciprocation affects the build-up of the individual social capital of bloggers, as measured by their links and interactions with others. This allows us to measure the role of content production and relationship building in the dynamics of online social networks and to distinguish between the social networking and media aspects of blogging. 相似文献

The increasing use of family planning methods seems to be the intermediate determinant which mostly influences the fertility decline in developing countries, and in particular in those countries which are in an advanced phase of demographic transition such as Egypt. Moreover large countries, like Egypt, are characterized by very different geographical realities and even by strong regional heterogeneities. The aim of this study is the analysis of the determinants of contraceptive use in Egypt, with particular reference to the differentials due to the socio-economic context and to the area of residence. To estimate each individual and regional factors’ effect on contraceptive use, a logistic two-level random intercept model is fitted to EDHS 2000 data; the use of a multilevel analysis is suggested by the two-level data structure: the first level units are the women, the second level units are their regions of residence. 相似文献

The present study evaluated whether, and to what extent, the constructs implicated in the theory of planned behavior could predict behavioral intention to exercise and exercise-class attendance of older adults (age 65-90 years) already enrolled in a physical activity program. The study also evaluated whether including self-efficacy judgments might improve the predictive capacity of the model. Participants (N = 1,095) were randomly sampled Italian volunteers from exercise classes for older adults. First, they completed questionnaires assessing the above-mentioned constructs. Then, class attendance was recorded during the following 3 months. Results indicated a substantial correspondence between the model and the data. Perceived behavioral control and self-efficacy were the strongest predictors of behavioral intention, whereas attitudes and subjective norms only partially contributed to its prediction. The inclusion of self-efficacy improved the predictive capacity of the overall model. Finally, results showed a weak relation between behavioral intention and attendance rate in physical activity sessions. 相似文献
