This study investigated the monthly dynamics of social assistance benefit receipt – in particular the incidence of long‐term benefit receipt – in four European countries: Luxembourg, The Netherlands, Norway and Sweden. The analysis is based on four separate administrative panel data sets, each covering the 96‐month period from January 2001 to December 2008. Benefit dynamics were found to vary considerably across countries. In the two Nordic countries, long‐term benefit receipt was found to be a rare exception. Most recipients, however, had multiple spells and the majority of benefit leavers returned to benefits within a few months of leaving. In Luxembourg and The Netherlands, long‐term benefit receipt was frequent, but benefit leavers were much less likely to return to benefit receipt after exit. The total duration of benefit receipt per individual across spells was two to three times as high in The Netherlands and Luxembourg as in Norway and Sweden. 相似文献

Does the life cycle of economic papers differ across fields of economic research? By constructing and analyzing a large dataset that combines information on 9,672 articles published in the top five economic journals from 1970 to 2000 with detailed yearly citation data obtained from Google Scholar, we find that published articles do have a life cycle that differs across fields of economic research (which we divide into the categories of applied, applied theory, econometric methods, and theory). Applied and applied theory papers are the clear winners in terms of citation counts. For the first years after their publication, they receive higher numbers of citations per year than papers in other fields of research do. They also reach a higher peak number of citations per year and apparently sustain those peak levels for longer, in addition to being cited over longer periods of time (i.e., they have a longer lifespan). Citation patterns are much less favorable for theoretical papers, which are the object of fewer citations per annum in the first years following publication, have lower peak numbers and a shorter lifespan. Econometric method papers are a special case; the pattern for most of these papers is similar to the pattern for theory papers, but the most successful papers (as measured by the number of citations) on econometric methods are also the most successful papers in the entire discipline of economics.

With the fall of the Berlin Wall in 1989, open migration from East to West Germany became possible. Between 1989 and 2007, roughly 10 per cent of the East’s population at the time of reunification migrated from east to west. The emigrants were predominantly young and female. This selective migration pattern led to a tremendous deficit of females in the 18–29 year old age group in eastern Germany. Overall, the sex ratio in that age group is as low as 89 females per 100 males in the east. In some rural counties, the sex ratio is 80 females per 100 males. We find that excess female emigration at the county level is associated with gender disparities in educational attainment that favour women, a labour market structure that favours men and the lower availability of potential partners with similar levels of education in eastern Germany. 相似文献

We propose a parametric test for bimodality based on the likelihood principle by using two-component mixtures. The test uses explicit characterizations of the modal structure of such mixtures in terms of their parameters. Examples include the univariate and multivariate normal distributions and the von Mises distribution. We present the asymptotic distribution of the proposed test and analyze its finite sample performance in a simulation study. To illustrate our method, we use mixtures to investigate the modal structure of the cross-sectional distribution of per capita log GDP across EU regions from 1977 to 1993. Although these mixtures clearly have two components over the whole time period, the resulting distributions evolve from bimodality toward unimodality at the end of the 1970s. 相似文献

The invisible body of queer youth: identity and health in the margins of lesbian and trans communities 总被引:1,自引:0,他引:1
How does complexity in gender and sexual identity construction and partnering practices generate unique vulnerabilities for queer-identified youth? We present two case studies from an ongoing ethnographic study of LGBTQ youth development: "Samantha," a queer-identified woman partnered with a transgender man, and "Reid," a queer-identified transgender man who has declined medical gender transitioning and who partners with lesbians and gay men. We consider the implications of these youths' locations on the margins of both lesbian and transgender communities and the challenges in providing health care and support services for queer-identified youth. 相似文献

ABSTRACTWe have provided a fractional generalization of the Poisson renewal processes by replacing the first time derivative in the relaxation equation of the survival probability by a fractional derivative of order α(0 < α ? 1). A generalized Laplacian model associated with the Mittag-Leffler distribution is examined. We also discuss some properties of this new model and its relevance to time series. Distribution of gliding sums, regression behaviors, and sample path properties are studied. Finally we introduce the q-Mittag-Leffler process associated with the q-Mittag-Leffler distribution. 相似文献
