Businesses often need an accurate profile of their customers in order to better serve them, improve products and make advertising more effective. Unfortunately, customers do not always completely fill out the survey forms, especially those product registration cards. The forms often have multiple choice questions and customers may leave some questions blank. This paper presents a maximum likeli...

Explicit modeling of business processes and their enactment in work ̄ow systems have proved to be valuable in increasing the ef®ciency of work in organizations. We argue that enacted business processes Ð i.e. work ̄ow management systems Ð form a solid basis for adequate information support in complex and knowledge-intensive business processes. To support this claim we demonstrate results from two...

Paul Berg’s book “Random Walks in Biology” (1), describes a useful thought experiment that illustrates the diffusion phenomenon. Imagine carefully introducing a drop of colored fluorescent dye into a jar of water. Initially, the dye remains concentrated at the point of release, but over time, it spreads radially, in a spherically symmetric distribution. This mixing process is taking place witho...

Using US county data, we estimate employment growth equations to analyze how the spatial distribution of jobs has changed between 1972 and 2000. We find that total employment has become increasingly concentrated. This aggregate picture hides important sectoral differences though: whereas non-service employment has been spreading out, service jobs have clustered in areas of high aggregate employ...

We examine the effect of house price appreciation on bank loan portfolios during the 1996—2006 period. While most previous research in this area has concentrated on loan demand effects, we evaluate how house prices affect a bank’s credit supply. Controlling for possible simultaneity between house prices and bank loan portfolio growth, we find that banks affected by greater house price appreciat...

It proposes new model for management of cost efficiency, this model include also definitions of dimensions and indi...

In the mid-1990s, productivity growth accelerated sharply in the U.S. economy. In this paper, we identify several other industry-level changes that have occurred during the same time and argue that they are consistent with an increased use of information technology (IT). We use case studies to illustrate how IT has enabled firms to more rapidly replicate improved business processes throughout a...
