“…Observed a positive impact of the number of participating suppliers in the ERA, the degree of competition, price visibility, the monetary volume, and the number of lots on price reductions, and consider the consequences of ERAs on productivity and cycle time reduction, buyer-supplier relationship, and ethical improprieties, based on case study visits at 15 providers, 16 buying organizations and 15 suppliers Wagner and Schwab (2004) Identified eight conditions that have to be favorable in order to achieve lower purchasing prices in ERAs: ease of specifying demand, auction volume, expense of switching suppliers, number of suppliers participating, competition among suppliers participating, power of the buyer, complexity of the negotiation package, and time to auction, based on interviews with practitioners and academics Daly and Nath (2005b) Developed guidelines and principles for relationship marketers to help render ERAs more relationship-friendly, including subsidies for investment, price negotiation after the auction, and payments to losing bidders. Emiliani and Stec (2005), however, refute these guidelines and consider them to be misaligned with industry practice Hartley et al (2005) Studied the buyer's satisfaction with ERAs and find that ERA adopting buying organizations were more satisfied with the purchase price, than with the supplier relationship and the ERA process itself, based on a survey with 47 supply chain managers Pearcy et al 2007) Studied the impact of relational (versus discrete) governance structure of ERAs on purchase price, supplier cooperation and time savings across different purchase categories (standardized direct materials and maintenance, repair and operating (MRO) supplies) and find that a relational governance structure has a positive impact on supplier cooperation, but negatively influences purchase price reduction and time savings, based on a cross-industry mail survey of 142 purchasing professionals Carter and Stevens…”
