This paper discusses the problems in interpreting the correlation coefficient as a measure of geographical accessibility to public services by income groups. As an alternative a relative index is proposed which incorporates the unique limits to the correlation coefficient in any area and thus...

We investigate the nature of competitive equilibrium for brands competing in a multi-attribute product space when consumer preferences for product attributes follow nonuniform distributions. We establish subgame-perfect equilibria in a two-stage game, where firms choose positions in the first...

We offer new evidence on the link between price points and price rigidity using two datasets. One is a large weekly transaction price dataset, covering 29 product categories over an eight-year period from a large U.S. supermarket chain. The other is from the Internet, and includes daily prices...

The importance of distinguishing between potential and realized value for IT investments has been recognized by senior managers and IS researchers since some time in the 1980s, when it became apparent that not all IT investments were likely to achieve equivalent levels of return on investment....

Internet technologies should lessen information asymmetry, prompting competitive price reactions, but this does not seem to be happening in Internet-based selling. We study empirical regularities of price change timing for music CD vendors and booksellers to assess several theoretical...

The development of the information systems (IS) literature in Management Science during the past 50 years reflects the inception, growth, and maturation of several different research streams. The five research streams we identify incorporate different definitions of the managerial problems that...

There is increasing empirical evidence from academic research and strong recognition among policymakers that wide diffusion and innovative uses of digital wireless phones are important sources of a country's economic growth and social development. Adopters do not necessarily adopt digital...

We study the link between price points and price rigidity using two data sets: 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...
