How Do Adopters Transition Between New and Incumbent Channels? Georgia Tech Scheller College of Business Research Paper No. 2016-51

Eric M. Overby, Sam Ransbotham


There is substantial knowledge about how individuals and organizations – which we refer to collectively as entities – adopt and use new channels. However, less is known about how this relates to their use of the incumbent channel that the new channel may replace, particularly how this relationship varies across entities and over time. We study this both theoretically and empirically. First, we develop and validate a new typology of how entities’ use of new and incumbent channels evolves over time. Second, we generate novel insights about the post-adoption use behaviors of entities that adopt the new channel at approximately the same time. Third, we analyze how entities’ use of new and incumbent channels varies based on time of entry, which is when an entity first becomes active with either channel. Fourth, we identify and validate other explanatory variables for why entities transition between states of new/incumbent channel use. Our results contribute to theory about the adoption/diffusion of new channels, and they contribute to practice by giving managers tools to understand and predict how entities’ use of new and incumbent channels evolves over time.

Electronic Commerce, Spatial Arbitrage, and Market Efficiency Information Systems Research

H Subramanian, E Overby


Electronic commerce can improve market efficiency by helping buyers and sellers find and transact with each other across geographic distance. We study the effect of two distinct forms of electronic commerce on market efficiency, which we measure via the existence and exploitation of spatial arbitrage opportunities. Spatial arbitrage represents a more precise measure of market efficiency than does price dispersion, which is typically used, because it accounts for the transaction costs of trading across distance and for unobserved product heterogeneity. One of the forms of electronic commerce that we study is a webcast channel that allows electronic access to the traditional physical market, while the other is a standalone electronic market. Both forms provide traders with expanded reach to find and transact with each other across geographic distance, but only one allows traders to conduct transactions immediately, at any time. This variance helps us isolate the effect of these mechanisms (reach and transaction immediacy) on efficiency. We find that electronic commerce reduces the number of arbitrage opportunities (likely by expanding traders’ geographic reach) but improves arbitrageurs’ ability to identify and exploit those that remain (likely by expanding arbitrageurs’ reach and providing them with the immediacy to exploit opportunities quickly). Overall, our results suggest that electronic commerce improves market efficiency not only by helping buyers and sellers transact across distance (thereby balancing supply and demand across geographic locations) but also by helping arbitrageurs quickly exploit any remaining arbitrage opportunities (thereby rebalancing supply and demand across geographic locations).

How Reduced Search Costs and the Distribution of Bidder Participation Affect Auction Prices Management Science

Eric Overby, Karthik Kannan


Electronic commerce allows bidders to find and participate in auctions regardless of location. This reduction in bidders’ search costs has important effects on bidders’ participation patterns and sellers’ revenue. The “demand expansion” effect occurs when reduced search costs allow bidders to participate in more auctions. The “demand distribution” effect occurs when reduced search costs allow bidders to distribute themselves more evenly across auctions. We focus on the latter effect by modeling when a more even distribution of bidder participation across auctions increases seller revenue. We apply our analytical insights to 65,718 sequential auctions (comprising over 10 million vehicles) in the wholesale used vehicle market. We show that reduced search costs can increase seller revenue by smoothing the distribution of bidder participation across auctions, even if the aggregate amount of bidder participation remains constant. This contributes new results to the auction theory literature and generates novel insights for sellers seeking increased revenue.

The Effect of Electronic Commerce on Geographic Purchasing Patterns and Price Dispersion Management Science

Eric Overby, Chris Forman


The “law of one price” states that if prices for the same or highly similar goods vary across geographic locations by more than the cost of transport, then traders will shift supply and demand to exploit the price differences. However, several frictions prevent traders from doing this, including lack of information about prices and difficulty trading across locations. Electronic commerce has the potential to reduce these frictions by increasing price visibility and lowering transaction costs. We analyze this by studying how the diffusion of an electronic channel affected geographic trading patterns and price dispersion in the wholesale used vehicle market from 2003 to 2008. We find that buyers used the channel to shift their demand geographically to exploit price differences, which reduced geographic price dispersion. We find that the electronic channel also influenced how sellers distributed supply, but we find little evidence that this led to reduced geographic price dispersion.

Physical and Electronic Wholesale Markets: An Empirical Analysis of Product Sorting and Market Function Journal of Management Information Systems

Eric Overby & Sabyasachi Mitra


Markets can yield significant economic benefits by improving transaction efficiency, but effective design is necessary to achieve these benefits. We compare a physical market to a discrete electronic market in the wholesale used vehicle industry to evaluate how their different designs work for different types of transactions. We find that buyers and sellers balance adverse selection costs and other transaction costs when using the two markets, with the physical market serving as the general exchange and the electronic market serving as a spot market for vehicles with low adverse selection risk. These findings increase our understanding of how sellers and buyers distribute supply and demand between physical and electronic markets in industries in which they coexist. They also increase our understanding of how information technology can improve market function in wholesale environments.
