Valuing externalities from energy infrastructures through stated preferences: a geographically stratified sampling approach

Valuing information technology infrastructures: a growth options approach

Decisions to invest in information technology (IT) infrastructure are often made based on an assessment of its immediate value to the organization. However, an important source of value comes from the fact that such technologies have the potential to be leveraged in the development of future applications. From a real options perspective, IT infrastructure investments create growth options that ...

Calibration approach estimators in stratified sampling

Calibration is commonly used in survey sampling to include auxiliary information to increase the precision of the estimates of population parameter. In this paper, we newly propose various calibration approach ratio estimators and derive the estimator of the variance of the calibration approach ratio estimators in stratified sampling. r 2006 Elsevier B.V.

Combining Revea|ed and Stated Preferences Data

Our objective is to develop a unifying framework for the incorporation of different types of survey data in individual choice models. We describe statistical methodologies that combine multiple sources of data in the estimation of individual choice models and summarize the current state of the art of data combination methods that have been used with market research data. The most successful app...

In times of ubiquitous electronic communication and increasing industry pressure for standard electronic authentication, the maintenance of privacy (the “right to be let alone”) becomes a subject of increasing concern. The possibility of a “transparent human” appears most obvious in electronic commerce, due partly to the large amounts of data available, partly to the high payoffs expected from ...
