“…Among the studies of police wages, the mechanism that has been the most widely explored is how unions and unionization shape public-sector occupations in general and police pay specifically (Ashenfelter, 1971; Ehrenberg, 1973; Ehrenberg & Goldstein, 1975; Frandsen, 2016; Freeman, 1986; Hunter & Rankin, 1988; Jennings & Borrelli, 1994; Wilson, Zhao, Ren, & Briggs, 2006). There have been several important studies addressing the positive relationship between unions and police wages and salaries (Bartel & Lewin, 1981; Doerner & Doerner, 2010; Feuille & Delaney, 1986), and the general findings are that unionized police departments experience additional rewards and lower rates of accusations of excessive force (Jenkins & DeCarlo, 2015).…”
