I would like to sincerely thank him for his guidance, carried out with patience and respect. He has always been there to discuss any major concern and to help me solving any trouble I faced during the work. His hints and suggestions leaded me to constantly improve my research. Despite his many commitments, prof. Curini has always found a way to supervise my work with accuracy, even when we were several time zones away from each other. Far from any rhetoric, I have really much appreciated his helpfulness. I am also grateful to some other people who gave me suggestions about how to improve the present work. In particular, I would like to thank Prof. Paolo Martelli who devoted time to revising one chapter of the present work, giving me useful ideas to clarify some aspects of the dissertation before writing the final handout. In turn, Prof. Fabio Franchino gave me some hints to improve one empirical chapter and he deserves my gratitude for that. I would like to thank Prof. Gary King, for hosting me at the Institute for Quantitative Social Science (IQSS), Harvard University, and for his advices about how to make my research more interesting, as well as Prof. Stefano Iacus for helping me to join the IQSS. I really appreciated the time spent there, and such experience contributed in several ways to enhance the quality of my work. In this sense, I also thank Professors Stephen Ansolabehere, v Nahomi Ichino, James Snyder and Arthur Spirling for their politeness. They devoted their time to read and discuss with me some points of the present dissertation and indeed the final version of my research benefits from their hints and suggestions. Along the same vein, I am grateful to the discussant and to the participants at the Research Workshop in Comparative Politics, Harvard University, where I presented an early draft of the present research. All the smart comments that I received there have been precious and I tried to take them all into account, in order to improve my study. That said, I cannot leave aside my family. My parents, Nicolangela and Vittorio, and my brother, Simone who always supported me and did their best to help me realize my dreams. I also want to thank my grandfather, who fostered my passion for politics since I was a kid, as well as my father did. They also brought me to a local party congress when I was seventeen and, in a sense, that was the day when the present research began. To conclude, I want to say thank you to my friends. First of all, my best friend Alessandro, whose voice is the only one I usually listen to; my crew, that will never exit from my life, no matter where we will be; my `group' that leaded me to discover the importance of loyalty while pursuing a common passion. Last, but not least, I want to thank my `Bostonian' friends, i.e., those that hopefully have been reading through these lines: I promise I'll bring you an hard copy, someday. vi Contents List of Figures 1 List of Tables 3 1 Introduction 7 1.1 Why Factions? . .7 1.2 Literature on Intra-party Politics and Party Factions . 12 1.3 Intra-party politics and the Party System . 20 1.4 Where Do Factions Come From? . 23 1.5 How to Allocate Portfolios among Factions? . 24 1.6 Who Sets the Party Line? . 25 1.7 Why Does the Party Break Up? . 25 1.8 Does Intra-party Politics Affect the Party System? . 27 1.9 Outline of the Dissertation . 27 2 Factional Politics: A Theory of Party Unity and Party Fission 29 2.1 Introduction . 29 2.2 A Theory of Party Unity and Party Fission . 30 2.3 The Party Leader Selectorate: Autonomy or Dependence . 49 3 Analyzing Intra-party Politics: The Dataset on the Italian Case 55 vii 3.1 Factional Politics: The Italian Case . 55 3.2 Party Congress Arena: where Factional Bargaining Takes Place 62 3.3 From Words to Fact(ion)s: Measuring Factions' Policy Positions through Wordfish . 70 3.4 Assessing the Validity and the Reliability of the Estimates . 81 3.5 Changes in Political Language and Communication . 89 4 Where Do Factions Come From?
