We study how French exporters react to a VAT shock in a destination country. As VAT shocks are by nature almost permanent, exogenous, and without impact on marginal costs, the subsequent price reaction makes it possible to identify a pure demand-led mark-up adjustment. The results of an analysis...

A large exclusion from the labor market or an important unemployment of lowskilled workers is observed in numerous countries that set a minimum wage. Unemployment benefit or subsidizing low-skilled job policies can be mixed to deal with this situation. We introduce a matching model where (i)...

We introduce a matching model that allows for classical and frictional unemployment. The labor market is dual featuring low-skilled and high-skilled workers and simple and complex jobs. Simple jobs pay a minimum wage, while wages in the complex jobs are determined by Nash bargaining....

This article provides a comparative analysis of changes in numerical and functional labour flexibility in the French and the UK food processing industry. Based upon case study data, it explores the interaction between competitive pressures and institutional and regulatory structures and their...

This paper analyses whether it is worth taxing the black market. A theoretical optimal tax model provides a first analytical discussion. An empirical version allows us to estimate an optimal tax system for Madagascar. For reasonable inequality aversion parameters, the taxation’s rate of the...

The purpose of this paper is to explain why low-wage workers with identical qualifications to higher-wage workers are more exposed to unemployment. Each worker is considered to belong to a social group (defined according to his/her gender, age, and nationality). We assume that workers experience...

Following the adoption of information and communication technologies (ICT), firms may react to increasing skill requirements either by training or hiring the new skills, or a combination of the two.Using matched datasets with about 1,000 French plants, we assess the relative importance of these...
