The paper investigates temporary layoffs on the Swedish labour market. Previous reports of few temporary layoffs are rejected. About 45% of the unemployed people who found a job, returned to a previous employer. As a stock measure, 10% of the unemployed are on temporary layoff. Using new job and recall as distinct exits in a competing risks model, one cannot reject a horizontal duration depende...

This paper studies the survival of fixed exchange rate regimes. The probability of an exit from a fixed exchange rate regime depends on the time spent within this regime. In such a context durations models are appropriate, in particular because of the possible non-monotonic pattern of duration dependence. Non-parametric estimates show that the pattern of duration dependence exhibits non-monoton...

Using the methodology developed in Alvarez et al. (2014), we decompose variance of unemployment duration Spain into three main components: labour market frictions, dependence and heterogeneity. Crucial to our analysis are comparisons by different demographic groups over business cycle shed light mechanisms behind dependence. We offer a general approach for interpreting administrative data that ...

A growing body of preclinical evidence indicates that addiction to cocaine is associated with neuroadaptive changes in frontostriatal brain systems. Human studies in cocaine-dependent individuals have shown alterations in brain structure, but it is less clear how these changes may be related to the clinical phenotype of cocaine dependence characterized by impulsive behaviours and compulsive dru...
