In many research papers the research methodology section gives details of the context and data gathering strategy however the data analysis process often remains a mystery. In an aim to increase collective reflection on data analysis, this article adds to emerging literature on the subject....

A proposal for maintaining privacy protection in large data bases by the use of partially aggregated data instead of the original individual data. Proper micro aggregation techniques can serve to protect the confidential nature of the individual data with minimumal information loss....

A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and I concentrate on the numerics and...

Most prices and interest rates display fluctuating levels that embody extractable energy and equivalent amounts of money. Such fluctuations are also associated with varying degrees of uncertainty. Shannon's derivations of spectral entropy and information content offer computational techniques...

In this paper we demonstrate that modeling e-business strategies is important in a time where the first e-business disillusionment has taken place. The objective of this Paper is twofold. First we propose a theoretical e-business model framework (eBMF) for aligning e-business initiatives and...
