Kselman Department of Political Science Duke University Date: March 30, 2009 Approved: ___________________________ Herbert Kitschelt, Supervisor ___________________________ Emerson Niou ___________________________ Timur Kuran ___________________________ Pablo Beramendi ___________________________ Judith Kelley An abstract of a dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Political Science in the Graduate School of Duke University 2009 Copyright by Daniel M. Kselman 2009 ABSTRACT A majority of formal theoretic research in political science treats political parties as unitary actors, and endows them with decision-making powers not unlike those of strategic individuals. In contrast, my dissertation examines strategic equilibria which arise when competition takes place simultaneously within parties over organizational control and between parties over political office. I first distinguish between three intra- organizational elements: a party’s parliamentary group , its activist cadre , and its executive leaders . Chapters 2-4 develop a set of foundational game theoretic models which identify the equilibrium balance of power among these 3 organizational elements as a function of a country’s electoral institutions and voters’ relative responsiveness to marginal policy changes. In turn, this more complete understanding of intra-party competition sheds light on a number of important questions in comparative politics and comparative political-economy. For example, it helps to identify conditions under which Duverger’s argument that proportional representation (PR) should tend to generate multi-party competition may not apply; and, in contrast to Lijphart’s famous argument, conditions under which PR may instigate rather than mediate social conflict. Ten months of intensive field research conducted in Turkey provide both the quantitative and the qualitative data which constitute the dissertation’s most basic empirical material, including a data set of over 3,000 observations on party-switching in the Turkish Parliament (1983-2007). iv Contents Abstract ......................................................................................................................................... iv List of Tables ............................................................................................................................... vii List of Figures ............................................................................................................................ viii Acknowledgements ..................................................................................................................... ix 1.
