All of the papers in this issue focus on the value of obtaining information about uncertainties. We begin with an article by J. Eric Bickel on "The Relationship Between Perfect and Imperfect Information in a Two-Action Risk-Sensitive Problem." Next, is an article by Philippe Delquié on "The Value of Information and Intensity of Preference." Our third article, which uses an example of an oilfield decision to demonstrate an approach to "Valuing Future Information Under Uncertainty Using Polynomial Chaos," is by Michael Prange, William J. Bailey, Benoit Couët, Hugues Djikpesse, Margaret Armstrong, Alain Galli, and David Wilkinson. In the final article, Thomas Eppel and Detlof von Winterfeldt describe the calculation of value of information about the contents of waste storage tanks in "Value-of-Information Analysis For Nuclear Waste Storage Tanks." Since information is the topic of this issue, our trivia question is about the late Jacob Marschak, from whom I learned about the economics of information and about clarity of thought.

Key Words: decision analysis; applications; energy; decision trees; expected utility; intensity of preference; Monte Carlo simulation; polynomial chaos; probability; uncertainty; value of information; two-action problem; editorial
