In this paper we show that performance information about “forgone” alternatives (i.e., alternative that were considered but not chosen) can have a significant impact on post-choice valuation. Our approach introduces a new and parsimonious way of looking at satisfaction that combines the literature on post-choice valuation with research regarding generalized expected utility theory. While the po...

We develop the notion of deformations using a valuation ring as ring of coefficients. This permits to consider in particular the classical Gerstenhaber deformations of associative or Lie algebras as infinitesimal deformations and to solve the equation of deformations in a polynomial frame. We consider also the deformations of the enveloping algebra of a rigid Lie algebra and we define valued de...

BACKGROUND There is a dearth of data relating UK general practice workload to personal and social markers of individual patients. AIM To test whether there is a significant association between general practice patient contact rates and the council tax valuation band of their residential address. DESIGN OF STUDY Cross-sectional analyses using data recorded, over 1 year, for over 3300 general...

We develop a valuation theory for generalized polygons similar to the existing theory for dense near polygons. This valuation theory has applications for the study and classification of generalized polygons that have full subpolygons as subgeometries.

All continuous linearly intertwining symmetric Blaschke valuations on convex bodies are completely classified. It is shown that there is a unique non-trivial such valuation. On symmetric bodies, this valuation is the curvature image operator.

Revealed preference techniques are used to test whether a data set is compatible with rational behaviour. They are also incorporated as constraints in mechanism design to encourage truthful behaviour in applications such as combinatorial auctions. In the auction setting, we present an efficient combinatorial algorithm to find a virtual valuation function with the optimal (additive) rationality ...

Contingent valuation of the environment has proven popular amongst environmental economists in recent years and has increased the role of monetary valuation in public policy. However, the underlying economic model of human psychology fails to explain why certain types of stated behaviour are observed. Thus, good scope exists for interdisciplinary research in the area of economics and psychology...

This paper describes an abstract framework called valuation network for computation of marginals using local computation. In valuation networks, we represent knowledge using functions called valuations. Making inferences involves using two operators called marginalization and combination. Marginalization tells us how to coarsen a valuation by eliminating some variables. Combination tells us how...
