Comparing federal institutions: Power and representation in six federations

The study of comparative federalism is often hampered by the diverse range of federal institutional arrangements in practice, as well as the ambiguity surrounding the concept of federalism. This article identifies three main conceptual approaches to federalism – sociological, constitutional, and governmental – then proposes a revised governmental approach that takes account of the institutional effects of federalism, for application in comparative politics research. Minimally defined, all federations are products of institutional rules that create separate territorial spheres of authority. This article compares Canada, the United States, Australia, Austria, Germany and Switzerland along two key institutional dimensions that structure politics in the federal state: resource allocation, and the representation of constituent units in federal-level decision-making.
