“…In the franchising literature, different types of monitoring costs, understood in a similar vein, have been estimated through indicators such as urban location (Norton, 1988;Lafontaine, 1992), distance between each outlet and the headquarters of the franchisor (Brickley and Dark, 1987;Minkler, 1990), and density of the chain's outlets in each geographic area (Minkler, 1990;Brickley, Dark and Weisbach, 1991b;Carney andGedajlovic, 1991, Lafontaine, 1999;Kehoe, 1996). All of these works observe a higher proportion of franchising for higher levels of moral hazard or higher costs of control.…”
