We show that the dynamics of the taxes have an impact mainly on the hours worked while labor market institutions have a large influence on the rate of employment. However, our findings underline that there is an interaction between the two margins. The model is tested on four countries (US, France, Germany and UK) which experiment different tax and labor market dynamics since the sixties. Using this structural approach, we can then perform counterfactual experiments about the evolution of the policy variables and to compare welfare levels implied by policy changes
