Purpose Little is known about actual price savings generated by cooperative purchasing and nonmonetary advantages, disadvantages and impediments for the cooperative purchasing of complex or high-risk purchases. This paper aims to explore these topics by studying joint purchasing of pacemakers in The Netherlands. Design/methodology/approach To evaluate the magnitude of price savings, data on individual and collective prices for 18 hospitals was analyzed. In addition, 16 interviews were carried out with representatives of hospitals that participated and did not participate in the joint purchase. Findings Based on quantitative and qualitative data, the authors found large differences in price savings which can be attributed to scale, but mostly to knowledge of the group and renewing a contract in a technology-driven and developing market. Limited product choice – because of an organization joining a cooperative – constrained the attractiveness of cooperative purchasing, as end users may have specific product preferences. The consideration of preferences of end users is important toward successful joint purchasing of complex items. Social implications The authors argue that price savings because of scale are about 7% for smaller organizations and 4% for larger organizations. For smaller organizations with low specific knowledge and capacity for buying complex products, economies of process and knowledge are more important reasons for joining a purchasing group than scale. For large organizations with high specific knowledge and capacity, scale is the most important reason. Originality/value This study combined qualitative and quantitative perspectives, using actual spend data, to investigate cooperative purchasing of high-risk or complex purchases. On the one hand, more insight into the magnitude and reasons for price savings is provided than in earlier literature. On the other hand, more insight is given in qualitative reasons for joining a group and challenges for cooperative purchasing of complex items.

Joint Purchase

The paper explored the conditions for retailers to implement option contract and the strategies to make joint purchase in spot market. Under the condition of uncertain market demands, a joint purchase model integrating batch ordering, option contract and spot market has been developed. Considering price fluctuation, the conditions for implementing option contract-based ordering have been studied; the impacts of price fluctuation and option execution price on retailers optimal ordering of joint purchase have been analyzed as well. The result shows that if a retailer adopts a joint purchase strategy, certain constraints need to be met. Otherwise, it is more conductive for the retailer to maximize revenues by adopting a single purchase order. When the spot market is involved, the total order quantity and the order quantity of option contract are negatively correlated with the option execution price and are positively correlated with the spot price fluctuation; and, the order quantity of bulk order contract is positively correlated with the option execution price and is negatively correlated with the spot price fluctuation.

Joint Purchase

Purpose – The purpose of this paper is to provide an assessment of a one-year pilot exploring the joint purchase of e-books via demand-driven acquisition (DDA) conducted by engineering librarians from seven members of the Borrow Direct interlibrary loan partnership. Also provided are observations that may inform future initiatives of a similar nature. Design/methodology/approach – The author presents a case study approach and examination of the results. Findings – The pilot was discontinued as a result of dissatisfaction with its configuration, but it did offer significant financials savings as well as provide accessible copies of mutually acquired titles to each member. The pilot also offered several lessons that can inform future joint e-book endeavors. Originality/value – Multi-institutional joint e-book DDA acquisition has been attempted elsewhere; however, what is unique about this pilot is that it was managed by seven independent institutions without a central legal entity to oversee it. This paper is a follow-up to the author’s presentation at the 80th IFLA World Library and Information Congress, August 16-22, 2014, in Lyon, France.

Joint Purchase

The attractive huge prize causes people to adore lotteries. Due to the very small probability of winning prizes, the players can enhance their probability of winning by using the method of joint purchase. In spite of many lottery schemes having been proposed, most e-lottery schemes focus on the players’ privacy or computation overhead rather than support a joint purchase protocol on the Internet. In this paper, we use the multisignature and verifiable random function to construct a secure and fair joint e-lottery scheme. The players can check the lottery integrity, and the winning numbers can be verified publicly.
