Equilibrium Cost Overruns
Cost overruns are endemic in military procurement projects and pervasive in other areas. This paper studies a model in which the apparent cost overruns arise not as systematic expectational errors but as equilibrium phenomena. The possibility of renegotiating payments when cost overruns occur results in firms bidding below their true estimate of expected project costs. This can cause the initia...
متن کاملHow large are software cost overruns? A review of the 1994 CHAOS report
The Standish Group reported in 1994 that the average cost overrun of software projects was as high as 189%. This cost overrun number is used as input in recent governmental reports on software development and as benchmark for several recent projects’ estimation performances. It is therefore important that we can trust this number. More recent cost overrun results reported by the Standish Group ...
متن کاملModel SSC LHC
We explore the possibility that Z ′ couplings can be probed using decay modes which involve neutrinos once Standard Model backgrounds are directly determined by the data itself. For some models, sufficient statistics are available at either the SSC or LHC to render these modes useful for coupling determina-tions, provided the mass of the Z ′ is not much larger than 1 TeV, if we assume other new...

متن کاملSSC: Statistical Subspace Clustering
Résumé. Cet article se place dans le cadre du subspace clustering, dont la problématique est double : identifier simultanément les clusters et le sousespace spécifique dans lequel chacun est défini, et caractériser chaque cluster par un nombre minimal de dimensions, permettant ainsi une présentation des résultats compréhensible par un expert du domaine d’application. Les méthodes proposées jusq...
