“…Most empirical research, however, suggests that although unions do raise municipal salaries, the union wage advantage generally falls in the 2% to 16% range, no higher than the impact of private sector unions (Ehrenberg and Goldstein, 1975;Ashenfelter, 1971;Ehrenberg, 1973;Freund, 1974;Karper and Meckstroth, 1976;Hall and Vanderporten, 1977;Kearney and Morgan, 1980;Smith and Lyons, 1980). There are some opposing findings (e.g., Edwards and Edwards, 1982), including a recent study (Hunter and Rankin, 1988) that indicates that municipal unions may have more impact on fringe benefits than on salaries.…”
