We analyzed the market for indivisible, pure status goods. Firms produce and sell di¤erent brands of pure status goods to a population that is willing to signal individual abilities to potential matches in another population. Individual status is determined by the most expensive status good one has. There is a strati…ed equilibrium with a …nite number of brands. Under constant tax rates, a mono...

Partial redundancy elimination (PRE) is a code optimization algorithm that simultaneously performs common sub-expression and loop-invariant motion. Traditional PREs analyze the entire program eliminate redundancies. By contrast, demand-driven PRE (DDPRRE) proposed as an to only part of determine whether each expression redundant by query propagation. The previous DDPRE reduces analysis time bec...

A hot spot of a program is a program region, whose execution time crucially impacts the overall execution time of the program. A hot spot can often be optimized without fully analyzing the whole program. This is supported by approaches for demand-driven data-flow analysis. Particularly successful in practice turned out to be an approach based on reverse data-flow analysis. In this paper, we rec...

Traditionally, vertical integration has concerned industrial economists only insofar as it affects market outcomes, particularly prices. This paper considers reverse causality, from prices – and more generally, from demand – to integration in a model of a dynamic oligopoly. If integration is costly but enhances productive efficiency, then a trend of rising prices and increasing integration coul...

Many clustering protocols for mobile ad hoc networks (MANETs) have been proposed in the literature. With only one exception so far [1], all these protocols are proactive, thus wasting bandwidth when their function is not currently needed. To reduce the signalling traffic load, reactive clustering may be employed. We have developed a clustering protocol named “OnDemand Group Mobility-Based Clust...
