Migration
Net benefits

The economic effects of migration on host countries depend on the levels of welfare benefits afforded to migrants and their contributions to government revenues through payments of direct and indirect taxes. In Discussion Paper No. 934, René Weber and Research Fellow Thomas Straubhaar use data from the Swiss Statistical Office's 1990 Consumer Survey to investigate whether resident foreigners are a burden or a benefit for the Swiss public transfer system. These combine detailed records of households' income and expenses together with social security and tax data and details of age, nationality, employment and qualifications for some 12,000 households. Their results indicate that each foreign household made an average net contribution of some $1,700 to the public transfer system. This `snapshot' approach cannot measure the full effects of migration over the life-cycle or changes in the population's demographic composition, however, or the possible impact of the business cycle.

The results of Weber and Straubhaar's regressions indicate that the age and level of qualification of the head of the household and the number of children all affect the transfer balance for sub-samples of foreign and native households, and estimating the resulting model for the entire sample with a dummy variable for foreign households reveals that these are still more likely to make a positive net contribution to the public budget. The government's provision of public services is equivalent to disseminating a large bundle of rights of use. Immigrants acquire some of these automatically on entering the host country (while forgoing similar claims in their home countries) and they also generate costs as the use of public infrastructure such as roads, schools and hospitals increases (although these may be offset by their contributions to the public budget through taxes). Weber and Straubhaar conclude that their empirical results provide no support for such a theoretical justification for restricting numbers of immigrants: in Switzerland, resident foreigners are most likely to be net contributors to the government budget.
