Over the years, competitions have been important catalysts for progress in Artificial Intelligence. We describe one such competition, the Trading Agent Competition for Supply Chain Management (TAC SCM). We discuss its significance in the context of today’s global market economy as well as AI research, the ways in which it breaks away from limiting assumptions made in prior work, and some of the...

A near ubiquitous feature of user interfaces is feedback on task completion or progress indicators such as the graphical bar that grows as more of the task is completed. The presumed benefit is that users will be more likely to complete the task if they see they are making progress but it is also possible that feedback indicating slow progress may sometimes discourage users from completing the ...

Users of information technology (IT) often encounter “progress indicators” during their interactions. These graphics (e.g., progress bars) appear on computing screens as users wait for a task to complete. The purpose of progress indicators is to inform users of the progress being made to complete a task. This study employs two theoretical models from psychological research on human waiting to d...

This paper is a contribution to the continuing development of the methods and results for the Index of Sustainable Economic Welfare, also known as the Genuine Progress Indicator (GPI). It attempts a more systematic approach to some of the components of the GPI. It includes a more careful specification of types of capital and more plausible methods of estimating the costs of depletion of non-ren...
