This article proposes a quantitative evaluation of interactions between GDP per capita, unemployment and permanent immigration in France over the period 1994-2008. Immigration is measured through the delivery of residence permits granted for more than one year to foreigners coming from non-European countries and is decomposed by delivery motives. The estimation of VAR models provides the following results. The immigration rate, and in particular family migration, has a positive and significant effect on GDP per capita, whereas its impact on unemployment is not significant. Moreover, the GDP per capita has a positive and significant impact on immigration rate while unemployment rate has a negative and significant impact on the working immigration rate.
