Employing methods extracted from the literature, in combination with data on the Dutch economy, we assess the impact of immigration on the labour market and the public sector in the Netherlands. Additional labour supply due to immigration will have only a limited positive effect on the total income of natives, though redistribution between native groups is relatively large. The long run fiscal impact of immigrants will only be positive if their labour market performance at least equals that of natives. We conclude that selective labour immigration may contribute to the economic well-being of the host country. However, large-scale immigration of labour is not considered to be effective in alleviating the financial burden of ageing in the Netherlands.
