Abstract: | This article examines whether spending decisions in Swiss cantons are interdependent, that is, whether the spending decisions of a canton are influenced by those of other cantons. Theoretically, fiscal policy imitation among cantons can be interpreted as a process of policy and innovation diffusion, as a result of tax competition or as a consequence of federalism as a policy laboratory. The panel analysis presented in this article provides evidence of the existence of budget spillovers among neighbouring cantons. Cantonal governments do not take spending decisions in isolation, but by systematically comparing the fiscal policies in neighbouring cantons. |
