Prevention policies against flood, such as dams or levees, are commonly designed by local jurisdictions and for most, they exert externalities on neighbouring jurisdictions. We study a model in which each jurisdiction chooses its collective prevention effort depending on the flood risk and on...

The presence of nearby public facility contributes to real-estate’s value, that’s why the market may expect impact of public project on house’s price. But undesirable and semi-desirable facility location choices can be contested by close inhabitants, because they are source of negative...

We compare the performance of two incentive mechanisms in public goods experiments. One mechanism, the Falkinger mechanism, rewards and penalizes agents for deviations from the average contributions to the public good (Falkinger mechanism). The other, the compensation mechanism, allows agents to...

We consider an auction setting, in a symmetric information framework, in which bidders, even if they fail to obtain the good, care about the price paid by the winner. We prove that the outcome of the first-price auction is not affected by identity-independent price externalities, while the...

We exploit French customs’ firm-level data to study how exporters pass a change in the VAT rate of one importing country through their prices. Looking at this reaction is of interest beyond a mere fiscal incidence analysis: VAT shocks provide instruments to identifying the extent of mark-up...

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...

Économie très largement ouverte, intégrée, située au centre de l’Europe, la France entre en concurrence directe avec ses voisins aussi bien en termes de marchés qu’en termes d’attractivité. Il lui est impossible aujourd’hui de réfléchir à son système fiscal sans prendre en...

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)...

Since the beginning of the 80’s, the developing countries have been forced to launch a fiscal reform. Most African countries are currently right in the middle of this reform process. This reform has two objectives: first, to increase fiscal pressure; second, to substitute domestic taxes to...

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....
