Abstract:
This article describes the impact of the Italian electoral reforms of 1993 on the structure of political alliances. The reform, which moved Italy from a pure proportional representation system to a mixed largely majoritarian system, was designed to increase transparency, reduce corruption, limit the number of political parties, and create the conditions for a politics of interests, rather than a politics of influence. Paradoxically, moving to a mixed electoral system had the opposite effect. In this article, the authors demonstrate this impact, by modeling the structure of political alliances at multiple levels (municipal, provincial, and regional) of the Italian polity from 1986 to 2001, from data on roughly 441,000 persons elected to serve in almost 3 million positions.

Abstract:
This article accounts for two puzzling paradoxes. The first paradox is the simultaneous absence and presence of attitude polarization, the fact that global attitude polarization is relatively rare, even though pundits describe it as common. The second paradox is the simultaneous presence and absence of social polarization, the fact that while individuals experienced attitude homogeneity in their interpersonal networks, their networks are characterized by attitude heterogeneity. These paradoxes give rise to numerous scholarly arguments. By deploying a formal model of interpersonal influence over attitudes in a context where individuals hold simultaneous positions on multiple issues we show why these arguments are not mutually exclusive and how they meaningfully refer to the same social setting. It follows that the results from this model provide a single parsimonious account for both paradoxes. The framework we develop may be generalized to a wider array of problems, including classic problems in collective action.
