“…The use of concurrent sourcing in the public sector is both examined in general (e.g. Brown et al, 2015; Miranda and Lerner, 1995; Warner and Hefetz, 2008) and in more specific areas such as water supply services (Porcher, 2016), refuse collection (Savas, 1977), school cleaning, information technology (IT) maintenance, road maintenance, and job activation (Hansen et al, 2011). Empirical results suggest that concurrent sourcing enhances competition in markets and secures internal production capacity at the public organization responsible for providing the service in the case the private supplier fails to deliver (Warner and Hefetz, 2012); in line with this, Hefetz et al (2014) find that total contracting out is used to a larger extent when the external supplier is another public organization, whereas partial contracting out is used to a larger degree when the external supplier is a for-profit organization.…”
