Technology developments have the potential to dramatically change the interactions between firms and their consumers. In recent years, technological improvements are occurring at a faster pace than ever before. Now companies are forced to learn quickly and react faster to remain competitive in the currently changing world. In my thesis, I explore some specific technological innovations, consider how consumers adjust, and discuss their managerial implications. In the first chapter I study the effects of consumer adoption of mobile banking on the banking industry. The proportion of US bank customers using mobile banking has grown from 29% in 2012 to 43% in 2015. This channel of interaction is likely to keep growing due to a further increase in the adoption of smart phones, improvement in quality of mobile banking apps and channel awareness. As a consequence, some banks have reported that they may reduce their number branches by half over the next decade. The adoption of mobile banking displaces many banking functions performed through other channels like: automated teller machines (ATM), telephone banking, and online banking. Using geo-coded transaction data from a large consumer bank, a dynamic structural model to represent consumers’ preferences is developed for online and physical channels. In this way changes in banking behavior due to variation in the branch network structure as well as the introduction of the mobile channel are considered. This model is used to predict the timing and type of transactions across channels. The knowledge gained with the demand model is then used to design an optimal branch network in terms of capacities, amenities, location, and number of branches. Counterfactuals allow the evaluation of different levels of channel adoption, and allows the consideration of their effect on banking transactions, and more important, the impact on customer loyalty. The model shows all channels remain relevant and, moreover, we found a strong complementarity between the physical and digital world. Therefore, instead of reducing the number of physical branches, banks should aim to adjust current branch capacities, specializing on transactions that cannot be served with digital channels. In conclusion, my findings suggest that digital channels will diminish–but never replace physical channels—and they should be redesigned correspondingly. Is important to note that this is the first time in the banking industry that of branches for digital channels are formally considered in a tool to support branch network design for the middle and long term. Internet shopping made possible interactive displays. In the second chapter, I discuss how arranging the products on a display or retail shelf can directly influence consumer purchases by facilitating or obstructing product search. Product proximity also influences competition and the set of products that a consumer considers. We show that when products are placed closer together competition between the products increases. Thus, product display can encourage consumers to purchase products that would not have previously been purchased. The motivation for the result is that consumer search is costly and consumers focus their search on local neighborhoods that are influenced by shelf position. Since search is costly, consumers may not exhaust all possibilities, which means that position could be an important determinant of consideration. To formally model this behavior, I create a sequential consideration model. To begin the search consumers are influenced by colors, favorite brand or the closest shelf edge, where few products can be considered. Then consumers shift their focus to neighboring products, in a sequential fashion, increasing the set of products considered, to finally making the purchase decision. By doing this, the display generates spatially induced consideration sets. Using this approach, we find that demand is greatly impacted by shelf position and retailers can create plan-o-grams that can shift demand from one product to another. Our focus on using shelf design to stimulate competition contrasts with past research on shelf design that has focused mainly on cost minimization. Using shelf-experiments from a supermarket retailer, Dominick’s Finer Foods, I show that re-arranging the products on the shelf can increase profits by up to 15%.
