While the average gender gap in pensions is quite well documented, gender differences in the distribution of pensions have rarely been explored. We show in this paper that pension dispersion is very similar for men and women within the French pension system of a given sector (public or private). Gender differences are less marked among retired civil servants than among former private sector employees. However, the determinants of these inequalities are not the same for men and women. Using a regression-based decomposition of the Gini coefficient, we find that pension dispersion is mostly due to dispersion of the reference wage for all retirees but gender differences exist. For women, in particular, pension dispersion is also due to the dispersion in contribution periods. We also decompose the Gini coefficient by source of pension to measure the impact of institutional rules (minimum pensions, survivor’s pension) on the extent of pension inequality. Unexpectedly, we find that the impact of minimum pensions is limited, although slightly larger for civil servants than for private-sector employees. Survivor’s pension schemes, on the other hand, contribute positively to pension dispersion among retired women.  相似文献

ABSTRACT: The works related to the disequilibrium theory often show that situations of classical unemployment and of Keynesian unemployment coexist on a long-term basis. The following study deals with a theoretical model of mixed unemployment reflecting this coexistence. In this model, prices are assumed to be flexible upward, but not downward. Hence, classical unemployment leads to inflation, without quantitative rationing on demand, which is closer to reality. The study analyses the asymmetric relations between the classical and the Keynesian sectors as well as the resulting implications for economic policy. What comes out is that differentiated policies always have a stronger impact than aggregate policies. The highest level of efficiency is obtained by stimulating the supply of firms set in the classical situation, provided that one acts on the non-wage determinants of supply in order not to further depress the outlets for firms set in the Keynesian situation.  相似文献

Condorcet efficiencies under the maximal culture condition   总被引:2,自引:1,他引:1  
The Condorcet winner in an election is a candidate that could defeat each other candidate in a series of pairwise majority rule elections. The Condorcet efficiency of a voting rule is the conditional probability that the voting rule will elect the Condorcet winner, given that such a winner exists. The study considers the Condorcet efficiency of basic voting rules under various assumptions about how voter preference rankings are obtained. Particular attention is given to situations in which the maximal culture condition is used as a basis for obtaining voter preferences. Received: 4 February 1998/Accepted: 13 April 1998  相似文献

There is now a large body of work that seeks to understand the evolution of planning systems across the globe, particularly the adaptation of planning to/under varying forms of neoliberalism. Some of this research seeks to provide empirical insights into new state spaces and the actors that occupy them. Others have made theoretical explanation of the reform agenda their goal. In sum much of the literature now points to an academic understanding of government policies on planning as representative of a ‘new moment’, characterized by a post-political narrowing of debate on what the fundamental objectives of the activity should be. In this contribution, we find grounds to agree with aspects of this analysis that takes the post-political as an explanatory framework. However, using the passage of the UK Localism and Decentralization Bill into law as the Localism Act 2011, we argue that the process of enacting planning reform was accompanied by acts of manipulation (heresthetics) and decontestation that accord more closely to traditional and long-standing methods of political action motivated by ideology.  相似文献

Several decades of interdisciplinary research have demonstrated the benefits of racially and ethnically integrated K12 schools. However, there is still much we do not know about what happens inside diverse schools that lead to these outcomes. In this article, we argue that the study of diversity in higher education, with its greater focus on internal institutional dynamics and a broader range of outcomes, can help K12 researchers fill in these gaps. However, the framework for studying diversity in higher education cannot be applied to K12 schools without first accounting for developmental and structural differences across students and sectors. To that end, this article summarizes the main components of the framework for studying diversity in the higher education literature—compositional, interactional, and organizational diversity—as well as the broad range of outcomes including not only academic achievement but also skills for lifelong learning and dispositions for citizenship in a multiracial democracy, and suggests how they can be adapted for K12 research. We argue that with this comprehensive but adapted framework, research on K12 education can inform practice and policy by providing more insight into the underlying mechanisms of school diversity and its consequences.  相似文献

We review five packages for estimating finite mixtures, BINOMIX, C.A. MAN, MIX, and the maximum likelihood routines of BMDP and STATA. The focus of the review is on numerical issues rather than matters such as user interface because the success or failure of an algorithm to yield a mixture model is likely to be the most important issue facing a researcher. The problem of suitable initial values is discussed throughout.  相似文献

This work deals with some parametric and semiparametric modeling approaches for count data distributions related to development of spiraling whitefly which is an insect pest collected in Brazzaville, Republic of Congo. In this study, the count data distributions are assumed to be modified Poisson probability mass functions. For the discrete semiparametric associated kernel estimator investigated, its almost sure consistency and asymptotic normality are shown under some asumptions. Some weighted Poisson models (WPD) are applied in comparison with the semiparametric approach for finite samples characterizing the growth of spiraling whitefly. Finally, the discrete semiparametric estimation is simple and effective for estimating any count distribution while WPD are practically more meaningful.  相似文献
