In this paper we estimate the impact of temporary employment subsidies for young long-)term unemployed workers in Belgium on the transition rate from employment to non-employment. We account for selective participation on the basis of a multivariate duration model with correlated unobserved...

In july 2004, the Belgian government intensified monitoring within the Unemployment Insurance scheme. Workers claiming unemployment benefits for more than 13 months are notified that past job-search behavior will be monitored 8 months later. In one region the target group is counseled shortly...

In Belgium unemployment insurance benefits can only exhaust for one category of workers : partners of workers with (replacement) labour income (mostly women) may loose their entitlement after an unemployment duration ranging from two to eight years, depending on individual characteristics. We...

Tiling arrays make possible a large-scale exploration of the genome thanks to probes which cover the whole genome with very high density, up to 2,000,000 probes. Biological questions usually addressed are either the expression difference between two conditions or the detection of transcribed...

The aim of this paper is to propose a test procedure for the detection of differential alternative splicing across conditions for tiling array or exon chip data. While developed in a mixed model framework, the test procedure is exact (avoiding computational burden) and applicable to a large...

This paper aims at estimating the effect on achievement of various types of schools: private, private but government-dependent and public ones. It is based on the analysis of Math, Science and Reading test scores of 15 year-olds students surveyed in 2002 across OECD and non-OECD countries. The...

The species abundance distribution and the total number of species are fundamental descriptors of the biodiversity of an ecological community. This paper focuses on situations where large numbers of rare species are not observed in the data set due to insufficient sampling of the community, as...

We here consider how Chinese firms adjust to higher minimum wages and how these affect aggregate productivity, exploiting the 2004 minimum-wage reform in China. We find that higher city-level minimum wages reduced the survival probability of firms which were the most exposed to the reform. For...

This paper uses Belgian firm-level data, covering the 1998-2006 period, to assess the impact on TFP growth of key labour force structural changes: ageing, feminisation and rise of educational attainment. Based on a Hellerstein-Neumark analytical framework, our work shows that an ageing workforce...

This paper investigates the problem of an "optimum population" concerning age structures in a 3-period OLG-model with endogenous fertility and longevity. The first-best solution for a number-dampened total social welfare function, including Millian and Benthamite utilitarianism as two extreme...
