This paper develops a search and matching model of equilibrium unemployment, with on-the-job search, extended to both the informal sector and entrepreneurship. Three are the key features of this model: the entrepreneurial ability affects job productivity, all unemployed start their job search in...

A matching model will explain both unemployment and economic growth by considering the underground sector. Three problems can thus be simultaneously accounted for: (i) the persistence of underground economy, (ii) the ambiguous relationships between underground employment and unemployment, and...

The economic crisis of 2008-2009, the most important that France knew since the Second world war, had a significant impact on the employment situation but, in relation with the fall of the production, the observed destructions of jobs were less large this time than during the recession of...

Relying on the non-negligible role played by the underground economy in the labour market fluctuations, this paper extends the standard matching model à la Mortensen-Pissarides by introducing an underground sector along with an endogenous sector choice for both entrepreneurs and workers. These...

This paper develops a labour market matching model in order to address the problem of the persistence of the hidden sector and of its regional concentration, as in Italy and in the enlarged Europe. The main novel features of the model are that entrepreneurial ability affects job productivity,...

This paper develops a standard matching model to address the problem of the hidden sector (including non-registered firms but producing for legal markets), as it is characterised in Italy, i.e. framed in a rather advanced economic and institutional setting, but also linked to the socio-economic...

Des exemples d’inégalité en éducation et de surqualification sur le marché du travail peuvent souvent se produire dans le même bâtiment administratif, comme par exemple un employé de bureau ayant un diplôme d’études supérieures et qui doit rendre compte à un supérieur n’ayant...

This paper shows that changes in the skill requirements of jobs are one way by which economic downturns affect job match quality. In doing so this paper makes two contributions to the literature. The first contribution is to document a stylized fact about the cyclicality of skill requirements...

Examples of educational mismatch and overqualifcation in the labour market can often be found in the same office building – the clerical worker with a bachelor’s degree reporting to a manager with a high school education – as an example. Some have argued that mismatch in...

We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...
