“…Inspired by the works of Schmitz (2013a) on public procurement and the works of Kwon (2006) on favoritism, this paper builds a principal‐agent model with moral hazard to explain seeming favoritism in public procurement. There are many studies focusing on moral hazard problems with a risk‐neutral and wealth‐constrained agent (see e.g., Crémer, 1995; Hoppe & Kusterer, 2011; Hoppe & Schmitz, 2010, 2013, in press; Innes, 1990; Laffont & Martimort, 2002; Ohlendorf & Schmitz, 2012; Pi, 2014, 2018; Schmitz, 2005, 2013a, 2013b), but they neglect to focus their attention on favoritism in public procurement. During the course of building the theoretical models, we use public procurement in the sense of Schmitz and his coauthors (e.g., Hoppe & Schmitz, in press; Schmitz, 2013a), which means that the government delegates the task to a firm in case of a single task or that the government delegates the tasks to different firms in case of multiple tasks.…”
