We compare the effects of migration on the production of public goods, income taxes, and on the welfare of residents in the sending and in the receiving country. Migration is driven by income di¤erences between countries. Alternative wage adjustment scenarios are considered: fully flexible wages; upward rigidity, and unemployment.
