Privatization in the telecommunications (Jordana and Sancho 2005; Schneider 2001), electricity (Eising and Jabko 2001), postal (Schmidt 1996a), railway (Kerwer and Teutsch 2001), and airline sectors (O'Reilly and Sweet 1998) has been studied in case studies, while quantitative studies cut across sectoral boundaries or study privatization in several sectors (Henisz, Zelner, and Guillén 2005; Schneider, Fink, and Tenbücken 2005; Zohlnhöfer, Obinger, and Wolf 2008).…”
