Several authors have argued that a centralization of fiscal powers in a federation is less likely to occur if citizens have to approve a change in the assignments of responsibilities by a popular referendum. This outcome may be due to the fact that logrolling is more difficult under direct than under representative democracy. It may also be caused by citizens’ fear that a centralization of fiscal authority facilitates the extraction of rents by the government or the legislature. In this paper, we test the hypothesis that centralization is less likely under referendum decision-making in the unique institutional setting of Switzerland. Using a panel of Swiss cantons from 1980 to 1998, the empirical analysis provides evidence that referendums induce less centralization of fiscal activities.
The paper compares decision-making on the centralisation of public goods provision in the presence of regional externalities under representative and direct democratic institutions. A model with two regions, two public goods and regional spillovers is developed in which uncertainty over the true preferences of candidates makes strategic delegation impossible. Instead, it is shown that the existence of rent extraction by delegates alone suffices to make cooperative centralisation more likely through representative democracy. In the non-cooperative case, the more extensive possibilities for institutional design under representative democracy increase the likelihood of centralisation. Direct democracy may thus be interpreted as a federalism-preserving institution.
