Job Assignments under Moral Hazard: The Peter Principle Revisited The Peter Principle captures two stylized facts about hierarchies: first, promotions often place employees into jobs for which they are less well suited than for that previously held. Second, demotions are extremely rare. Why do organizations not correct ‘wrong’ promotion decision? This paper shows in a complete contracting setti...

The high/low hierarchy respects the ordering of degrees, and so we can expect to find properties of order which are possessed by all degrees in a given hierarchy class. Such properties can also be found for classes of the generalized high/low hierarchy even though that hierarchy does not respect the ordering of the degrees. For example, Jockusch and Posner [4], extending a result of Cooper [l],...

In this paper, we will review the process of ev idence accumulation in the PSEIKI system for expectation-driven interpretation of images of 3-D scenes . Expectations are presented to PSEIKI as a geometrical hierarchy of abstractions. PSEIKI's job is then to construct abstraction hierarchies in the perceived image taking cues from the abstrac­ tion hierarchies in the expectations. The Dempster-S...

Contraction hierarchies are a simple hierarchical routing technique that has proved extremely efficient for static road networks. We explain how to generalize them to networks with time-dependent edge weights. This is the first hierarchical speedup technique for time-dependent routing that allows bidirectional query algorithms.

Abstract This article suggests that one of the understudied and substantive ways in which actors produce transform social hierarchies classifications is by aligning mis-aligning genres. Alignments within across genres have furnished methods for construing evaluating qualities people – as examples, genre repertoires job applications or promotion dossiers. A fine attunement to new emergent semiot...

In the past we presented an algorithm to solve ordered constraint hierarchies based on a non-trivial error function using standard constraint satisfaction techniques. We extended this previous work and herewith present a new method to transform hierarchies of inequalities over the integers based on global comparators into equivalent ordered constraint hierarchies. The correctness of this method...
