Introduction to the special issue: technology in retailing From the early days of retailing, and the simple buying, selling, and trading of goods in a central market, retailers have continued to explore ways in which to improve their performance (Leach, 1993). Historically, the improvements in product development, acquisition of goods, and retail operations were aimed at improving the performance of the retailer ( Johnston, 2014). Examples such as in-store technology and retail processes (Pantano and Laria, 2012), and the rapid growth of the internet (Laseter and Rabinovitch, 2012) helped lead the retail sector to representing almost one third of the global GDP, with the top 250 retailers in the world generating sales over $4 trillion USD (Deloitte, 2017). The breadth of the retail sector has resulted in retailing jobs being the leading source of employment in many countries (Luce, 2013), and although the largest retailers are led by traditional bricks and mortar retailers, ecommerce firms such as Amazon and Alibaba are advancing quickly (Gensler, 2017).The transition of bricks and mortar retailers into providing online shopping, or online ordering and store pick up options, can be linked to the advancement in the use of technology to decrease retailer operational costs while also providing greater flexibility in how consumers shop (Lee, 2015). These advancements are not surprising, given the rapid growth of pure-play online retailers, with Amazon being the most prominent. Retailers viewed technology as a way to decrease costs, both in-store and at the back end (i.e. distribution and supply chain activities), and thus being able to maintain retail price levels. Innovations in the area of in-store displays (Breugelmans and Campo, 2011, and electronic price labels; McKenzie and Taylor, 2016) are just some of the areas where retailers are utilising technology to improve operational and customer performance.The increased dependency upon technology also provided retailers with greater degrees of data and information, information that can be used to pass on process and operational improvements to their suppliers. Arguably, this drive for cost reduction, particularly on the production side, has reached a trough. There are a number of examples where suppliers have had to turn down large contracts with retailers, as they could no longer meet the retailers' demands for constant price reductions, or even forcing the retailer to accept price increases (Shah, 2017). In turn, traditional retailers were forced to look at ways in which technology would allow them to compete with online retailers, who operated on a lower cost operational model (Rowley, 1996). Retailers needed to refocus on their customer and ways in which they could improve the shopping experience. Through the implication of self-checkout systems, increased online information presence, and greater options in terms of product delivery and pick up, retailers have continued to examine ways in which technology could drive these changes (Renko and Druzijanic, 2014).In...
