" The authors seek to determine how immigration affects the employment and unemployment of nationals in Italy. To this end, they apply a probit model to measure the extent to which the presence of migrant workers affects the probability that national workers will find jobs or lose the ones they have. Particular methodological problems are resolved by applying the model to homogeneous areas defined either by regions or by regions and sectors. The results show that, except during specific periods, migrant labour has a complementary rather than a competitive effect on the labour market."
