Degree awarded June 2013 ii © 2013 Joseph Deckert iii DISSERTATION ABSTRACT Joseph Deckert Doctor of Philosophy Department of Political Science June 2013 Title: Patterns of Fraud: Tools for Election Forensics Election fraud is a serious problem in a number of modern democracies. While election observers can combat this problem to some extent, election forensics aims to provide a low-cost supplement. Forensic tools uncover irregular patterns in aggregate election data which are consistent with fraud. This dissertation improves upon existing tools and establishes methods of controlling for other factors which could cause irregular patterns. These tools are utilized in three cases studies in an effort to better understand the nature of election fraud. iv CURRICULUM VITAE NAME OF AUTHOR: Joseph Deckert GRADUATE AND UNDERGRADUATE SCHOOLS ATTENDED: University of Oregon, Eugene California State University, Hayward Palomar College, Vista, California DEGREES AWARDED: Doctor of Philosophy, Political Science, 2013, University of Oregon Master of Science, Political Science, 2012, University of Oregon Master of Science, Economics, 2012, University of Oregon Bachelor of Arts, Political Science, 2005, California State University, Hayward AREAS OF SPECIAL INTEREST: Formal Theory and Methodology Political Economy PROFESSIONAL EXPERIENCE: Graduate Teaching Fellow, Department of Political Science, University of Oregon, 2007-2012 GRANTS, AWARDS, AND HONORS: Graduate Teaching Fellowship, Political Science, 2007-2012 v ACKNOWLEDGMENTS I would like to express a great deal of gratitude to my advisor, Mikhail Myagkov.
