Power Inequality in Inter-municipal Structures: The Simulated Impact of a Reform in the Case of the Municipalities in Western France

Abstract

This paper deals with an important issue concerning democratic government: how delegates are to be allocated among jurisdictions in a federal system. More precisely, we analyze the effect of the 2010 inter-municipal reform in France, which changed the allocation of delegates between municipalities within their inter-communal structures. Using the theory of power indices and a unique set of data gathering 377 inter-municipal structures for three French regions, we compare the fairness of the distribution of municipal delegates prior to the 2010 reform to that of the new distribution, by simulating the impact of the 2010 reform. We show that this inter-communal reform may have increased power inequalities among municipalities belonging to the same inter-communal structure.
