Explaining the trasitions out of unemployement in Spain : the effect of unemployement insurance
In this article we study the factors that affect the transitions out of unemployment in Spain. We pay special attention to the impact of unemployment insurance benefits on the re-employment probability. We use a multinomiallogit model, and data from the EPA matched files from the second quarter of 1987 to the fourth quarter of 1995. Consistent with previous work, we find a negative effect of unemployment insurance receipt on the re-employment probability, and on withdrawal from the labor force. More importantly, we find a differential effect of benefit receipt when comparing time periods before and afier 1992. In april of that year the labor authority made eligibility requirements for unemployment insurance more restrictive, and curtailed benefit amounts
Towards a Generalized Hydrodynamics description of R\'enyi entropies in integrable systems
We investigate the steady-state R\'enyi entanglement entropies after a quench
from a piecewise homogeneous initial state in integrable models. In the quench
protocol two macroscopically different chains (leads) are joined together at
the initial time, and the subsequent dynamics is studied. We study the
entropies of a finite subsystem at the interface between the two leads. The
density of R\'enyi entropies coincides with that of the entropies of the
Generalized Gibbs Ensemble (GGE) that describes the interface between the
chains. By combining the Generalized Hydrodynamics (GHD) treatment of the
quench with the Bethe ansatz approach for the R\'enyi entropies, we provide
exact results for quenches from several initial states in the anisotropic
Heisenberg chain (XXZ chain), although the approach is applicable, in
principle, to any low-entangled initial state and any integrable model. An
interesting protocol that we consider is the expansion quench, in which one of
the two leads is prepared in the vacuum of the model excitations. An intriguing
feature is that for moderately large anisotropy the transport of bound-state is
not allowed. Moreover, we show that there is a `critical' anisotropy, above
which bound-state transport is permitted. This is reflected in the steady-state
entropies, which for large enough anisotropy do not contain information about
the bound states. Finally, we benchmark our results against time-dependent
Density Matrix Renormalization Group (tDMRG) simulations.Comment: 18 pages, 8 figures, similar to published versio

Employment transitions of young workers in Spain
In this article, we study the youth labour market in Spain. We focus on the transition from unemployment to employment and out of the labour force among two groups of workers: those who are looking for the first job, and workers who have already acquired sorne work experience. According to the SpanĂsh labour force survey (EPA), fĂrst job seekers represent more than fĂfty per cent of youth unemployment. By using matched files from the same data source we find that the employment transition rate among first job seekers is half of that for experienced young workers. Applying a multinomiallogit, we have analysed the factors that determine labour market transitions, and found significant differences between the two groups of job seekers. Inclusion of year durnmies in the regressions allowed to control for the effects of the economic cycle on transition probabilities
Mismatch in the Spanish labor market : overeducation?
The objective of this article is to explain the job match which is assessed by comparing attained education and job-required education as reported by workers. We frame our empirical work according to the occupational mobility theory. Using a cross-section of workers from a representative survey of the Spanish labor force, we consider overeducated workers to be those who report that the level of education their jobs require is below the level of education they have attained. Our results indicate that overeducated workers have less experience, decreased on-the-job training and higher turnover than other comparable workers. We also observe an improvement in the job match over age and mobility
