When manufacturers outsource operations to another company, coordination of the chain of production is crucial. George Vairaktarakis’s research studies the behavior of these organizations and how an environment of competition or cooperation affects results. Vairaktarakis investigates setting “fair” payments as incentives for cooperation, smart competitive rules that satisfy the companies and promote common interests, the value of information exchange, and the magnitude of production savings due to coordination. Vairaktarakis' findings often reduce production costs by 30% while improving service.
