We reexamine the •Information Technology (IT) productivity paradox• from the standpoints of theoretical basis, measurement issues and potential inefficiency in IT management. Two key objectives are: (i) to develop an integrated microeconomic framework for IT productivity and efficiency...

In a recent paper [Bowman, V. J., C. S. Colantoni. 1973. Majority rule under transitivity constraints. Management Sci. 19 (9, May) 1029-1041.] Bowman and Colantoni have described an optimization model which they relate to problems of majority voting in the theory of social choice. Their...

The paper presents a new approach to solving a class of combinatorial economic allocation problems. One member of this class is known as the quadratic assignment problem. Besides presenting an algorithm to solve this problem, we will discuss in general terms the techniques for treating...

This paper considers a class of algorithms for solving quadratic programming problems. An attempt is made to rank the various procedures. Computational results are given and a discussion of the results is presented.

We designed a platform with a betting mechanism for eliciting costly, dispersed information of different quality. Our objective is to elicit both dispersed information and the precision of the information so as to efficiently weight dispersed information to produce reliable forecasts. After...

Social broadcasting networks such as Twitter in the U.S. and Weibo in China are transforming the way online word-of-mouth (WOM) is disseminated and consumed in the digital age. We investigate whether and how Twitter WOM affects movie sales by estimating a dynamic panel data model using publicly...

Social broadcasting networks such as Twitter in the U.S. and "Weibo" in China are transforming the way online word of mouth (WOM) is disseminated and consumed in the digital age. In the present study, we investigated whether and how Twitter WOM affects movie sales by estimating a dynamic panel...
