We introduce a new class of parametric models applicable to a mixture of high and low frequency returns and revisit the concept of news impact curves introduced by Engle and Ng (1993). Overall, we find that moderately good (intra-daily) news reduces volatility (the next day), while both very...

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 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...

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...

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...

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....

We study the link between price points and price rigidity, using two datasets - weekly scanner data and Internet data. We find that (i) 9 is the most frequently used price-ending for the penny, dime, dollar, and ten-dollar digits, (ii) the most common price changes are those that keep the price...

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...
