“…For example, one school of thought focuses on market characteristics and argues that a principal managerial responsibility is to "manage the market" to engender competition (e.g., Brown & Potoski, 2004;Girth, Hefetz, Johnston, & Warner, 2012;. A related school of thought encourages purchasing governments to engage in joint or mixed delivery to stimulate competition between public and private providers (Bel, Brown, & Warner 2014;Hefetz, Warner, & Vigoda-Gadot, 2014) or to encourage relational or collaborative partnerships between the two (Bel & Fageda, 2011;Bel, Hebdon, & Warner, 2007). A third variant recommends performance management and incentives as a managerial tool to encourage successful contract outcomes Girth, 2014;Hefetz & Warner, 2004).…”
