    • A Strategic Analysis of Introduction Electronic Marketplaces Buyers often face substantial search costs in order to obtain information about the prices and product offerings of sellers in a By: J. Yannis Bakos market. These costs introduce Graduate School of Management inefficiencies into market-intermediated University of California, Irvine transactions and detract from the ability of Irvine, CA 92717 markets to provide an optimal allocation of productive resources. Interorganizational information systems can create “electronic Abstract marketplaces” by serving as intermediaries between the buyers and the sellers in a vertical market, in the Information systems can serve as process reducing the cost buyers must intermediaries between the buyers and incur to acquire information about seller the sellers in a vertical market, thus prices and product offerings.

This leads unique that they typically exhibit all five of to a single market price and offers buyers these characteristics. no incentive to compare the prices of different sellers. Stigler’s (1961) seminal Information systems researchers face the work titled “The Economics of Information” task of extending economic theory in the stimulated economists to ask how firms appropriate areas, drawing the proper and individuals behave, and how markets conclusions, and bringing the relevant function, when buyers and sellers do not results into the information systems field have perfect information about the (Bakos and Kemerer, 1990). In this spirit, consequences of their actions. In the the following two sections focus on the case of search costs, it can be shown that ability of electronic marketplaces to sequentially rational rules (i.e., rules that reduce the cost buyers face in obtaining describe a strategy that rational economic price and product information, and they actors would want to follow to the end) will illustrate how economic analysis can be be based on a reservation price, which is applied to study the forces driving the set so that the expected gain from economic and strategic implications of this searching once more equals the cost of technology. The discussion is the search (Rothschild, 1974). subsequently expanded to include the strategic impacts of three other Several authors have pointed out that the characteristics of electronic marketplaces actual distribution of seller prices may be identified above: large fixed costs, network unknown at the beginning, or it may externalities, and switching costs. change over time.

On the gets dynamically updated as new other hand, these models can information is gathered about seller demonstrate how even modest search prices). costs can lead to prices substantially higher than marginal costs, even in The impact of search costs in commodity markets and when the sellers commodity markets behave competitively (i.e., without any collusion). More recent work in this area Most search rules proposed in the suggests that the key in avoiding the literature, including the ones reviewed above problems lies in introducing above, have the following properties: (1) asymmetries in the buyer and seller sides seller prices decrease as the cost of of the market (i.e., allowing for search decreases; (2) the amount of heterogeneous buyers and sellers). search increases as the cost of search decreases; (3) the amount of search For example, in the real world not every increases as seller prices become more buyer has access to an electronic market dispersed; and (4) ceteris paribus, as system. Salop and Stiglitz (1982) have seller prices become more dispersed, studied a setting with two types of buyers buyers’ total costs decrease (buyers need who face different search costs. This is to search more when there is a wide similar to a scenario in which certain variety of seller prices, but they are buyers have access to an electronic compensated by better deals). market that provides information about seller prices at a low cost, while buyers The search costs faced by buyers allow without access to the electronic market the sellers to maintain prices at system face higher search costs. Their equilibrium substantially above their analysis suggests a mixed price marginal cost; it can be shown that, under equilibrium in which certain sellers charge certain assumptions about buyer behavior, high prices to take advantage of buyers at equilibrium all sellers charge the same with high search costs.

It is thus appropriate to extend standard Economists have been interested in models of differentiated markets to take differentiated markets since the late account of search costs. 1920s. A number of models have been proposed for their study, which generally One good candidate is the “unit circle” or fall in two categories: “city around the lake” model of spatial differentiation (Salop, 1979) in which seller • Spatial differentiation models trace offerings and buyer preferences are their origin to Hotelling’s (1929) located along a unit circle; buyers face a formalization of spatial competition.

It follows then that identified, keep searching, or give up. high search costs can lead to a market breakdown. This is in contrast to the case At the unique symmetric equilibrium each of free information, where some buyers seller charges a price that depends on the may stay out of the market because of search and transportation costs; the high transportation costs, but sellers higher these costs, the higher the prices always service their “local” markets.

Each buyer searches until a that electronic market systems providing product close enough to his preferences is product and price information may located.

About the Author J. Yannis Bakos is assistant professor of managment at the Graduate School of Managment, University of California, Irvine. He received his B.S. and M.S. degrees in electrical engineering and computer science from MIT an dholds an M.S. in management and a Ph.D. from MIT's Sloan School of Management. He focuses his teaching and research on opportunities for the strategic use of information technology. He has special interest in the application of industrial organization theory to the study of interorganizational information system snad their competitive implications. Professor Bakos also tracks and forecasts developments in end-user computing and coporate information systems architectures, especially in view of advances in communication stechnology. He lectures primarily in the areas of coporate telecommunication networks, information systems outsourcing, and the use of infomation technology for competitive advantage.
