The world economy is undergoing dramatic changes, largely driven by the new availability of fine-grained information. Innovative ways of using data—large and small—have also prompted a rethinking of the boundaries for the combination and use of knowledge. The strategic design of information flows in the economy has the upside of higher economic ren...

How effective is a hybrid pricing strategy for a cloud computing services vendor that mixes fixed-price reserved services with spot-price on-demand services? This research offers a decision support model to create the appropriate strategy for IT services based on prior research on information goods, electricity pricing, product versioning, and reve...
Article
We propose a model of software-as-a-service (SaaS) in a competitive marketplace that brings clarity to the choices that competing vendors must make for pricing and quality strategy. We focus on several features of SaaS competition, including differences in vendor offerings, incomplete information on application functionality, the potential lock-in...
Conference Paper
Recent research on cloud computing adoption indicates that there has been a lack of deep understanding of its benefits by managers and organizations. This has been an obstacle for adoption. We report on an initial design for a firm-level cloud computing readiness metrics suite. We propose categories and measures to form a set of metrics to measure...

With the emergence of new data collection technologies, advanced data mining and analytics support, there seems to be fundamental changes that are occurring with the resear...
Article
The early phase of diffusion plays a critical role in determining information technology (IT) success in a market. Takeoff, the transition point from the introduction to the growth phase in the IT life cycle, is viewed as an acid test for whether a technology will succeed. We develop a theory to understand global takeoff for digital wireless phones...

Article
This study examines the value of the time that a user spends to participate in a social game. We focus on how a massive multiplayer online role-playing game (MMORPG) vendor can establish prices to encourage participation and retain its players. We estimate value through an application of the hedonic pricing model and analyze a data set for an MMORP...
Article
As information technology (IT) becomes more accessible, sustaining any competitive advantage from it becomes challenging. This has caused some critics to dismiss IT as a less valuable resource. We argue that, in addition to being able to generate strategic advantage, IT should also be viewed as a strategic necessity that prevents competitive disadv...
Conference Paper
We model competition between software-as-a-service (SaaS) vendors by focusing on several key features of SaaS. These include: differences in vendor offerings; incomplete information for the clients side about the vendor’s capability to offer well-fitting services, and the clients’ learning costs and options to switch. Our findings suggest pricing s...
Article
Herd behavior arises in many instances of information technology (IT) adoption. This study examines the economic and behavioral bases for herd behavior and decision conformity. We investigate the roles of payoff externalities, observational learning and managerial incentives in influencing IT adoption decision-making. Our study underscores the bene...
Article
We compare two mechanisms from the buyer’s perspective in multi-attribute supply procurement, with verifiable and unverifiable quality of the supplies and risk aversion to deviation from acceptable quality: an auction mechanism and a generalized Nash bargaining mechanism. We develop a model to represent the effects on the buyer’s dominant strategy...
Article
We discuss the design of a hybrid mechanism for e-procurement, which implements a multi-attribute combinatorial auction, followed by a bargaining process to achieve desirable procurement transaction outcomes. For the auction phase of the mechanism, we discuss incentive-compatible bidding strategies for suppliers, and how the buyer should determine...
Article
ABSTRACT The Economics and Information Systems literature on technology adoption often considers network externalities as one of the main factors that affect adoption decisions.

Consumer behavior patterns related to home digital media use are changing due to technological innovations. We examine them in the presence of two-way cable television (CATV) set-top boxes. They permit viewers to change channels, switch to the Internet, and order paid programming, among other functions. We focus on micro-level data that are generat...
Article
Consumers in e-commerce acquire information through search engines, yet to date there has been little empirical study on how users interact with the results produced by search engines. This is analogous to, but different from, the ever-expanding research on clickstreams, where users interact with static web pages. We propose a new network approach...
Article
We discuss a two-stage mechanism for e-procurement operations, which implements a multi-attribute combinatorial auction in first stage, followed by bargaining in the second stage. We find that an important difference between single-unit and heterogeneous e-procurement auctions is the existence of different types among the winning suppliers. In the...
Article
Information technology (IT) services are often subject to down-ward price pressures due to improvements in technology and business processes in a competitive market. When clients enter into IT services contracts, they are faced with the future risk that their services will be overpriced relative to the broader IT services market. To mitigate this r...
Article
We use hedonic valuation to establish a basis for valuing the time a user participates in an online gaming community. We distinguish between utilitarian and hedonic value. Our application involves elements of both utilitarian and hedonic value, however, the latter is much more important. We use an extensive data set involving a massive multi-player...

The Internet has brought consumers increased access to information to make purchase decisions. One of the consequences is an increase in the price elasticity of demand, or the percent change in demand due to a percent change in price, because consumers are better able to compare offerings from multiple suppli- ers. In this paper, we analyze the imp...

Prior research shows that 9¢, 99¢, $9 and $99 in retail prices occur far more than expected. We investigate the extent to which these "'9' price-endings" occur in Internet-based selling, and explore what drives the observed variations. In particular, we explore theories based on customer perceptions of store quality image and rational inattention t...

The generalized second-priceauction mechanism is commonly used in research in the context of keyword advertising slot auctioning. The mechanism sets the clearing prices for advertising slots on a search engine’s Web pages such that the advertiser will pay what was bid for the next lower advertising slot each time their own higher-ranked hyperlink i...
Conference Paper
Full-text available
We evaluate the theory of strategic decommoditization. The theory suggests that firms can strategically utilize Internet technologies to "decommoditize" the products that are being sold. This prompts the consumer to make a purchase decision that is less focused on price. This is an important new direction in the use of Internet technology to sell p...

Article
Full-text available
We study the link between price points and price rigidity, using two datasets: weekly scanner data, and Internet data. We find that: “9” is the most frequent ending for the penny, dime, dollar and ten-dollar digits; the most common price changes are those that keep the price endings at “9”; 9-ending prices are less likely to change than non-9-endin...
Article
Internet-based group-buying auctions enable consumers to obtain volume discounts, but they face risk and trust issues that are not present in other e-retailing formats, which affects their adoption by consumers. Bidders experience uncertainty about the final auction price, and the risk of whether the auction will be completed. We evaluate textual c...
