We present estimates of the e ciency for nding QSOs as a function of limiting mag nitude and galactic latitude From these estimates we have formulated a target selection strategy that should net QSOs in the north galactic cap with an average of bers per plate not including bers reserved for high redshift quasars With this plan we expect of the targets to be QSOs The North Galactic Cap is divide...

I study e cient multi-unit auction design when bidders have private values, multiunit demands, and non-quasilinear preferences. Without quasilinearity, the Vickrey auction loses its desired incentive and e ciency properties. Instead of assuming that bidders have quasilinear preferences, I assume that bidders have positive wealth effects. This nests cases where bidders are risk averse, face fina...

Data envelopment analysis (DEA) is used here to determine the relative eciency of 24 top ranked US MBA programs. Eciency scores were determined using three output sets of the MBA programs: output that measured student satisfaction, output that measured recruiter satisfaction and output that measured both. DEA is also used here to determine the relative eciency of three foreign MBA programs a...

This paper discusses the literature on the enforcement of incomplete contracts. It compares legal enforcement to enforcement via relationships and reputations. A number of mechanisms, such as the repeat purchase mechanism (Klein and Le er (1981)) and e ciency wages (Shapiro and Stiglitz (1984)), have been o ered as solutions to the problem of enforcing an incomplete contract. It is shown that t...

This paper proposes a semiparametric maximum likelihood estimator for both the intercept and slope parameters in a binary choice model under symmetry and index restrictions. The estimator attains the semiparametric e$ciency bound in Cosslett (1987) under the symmetry and independence restrictions. Compared with the estimator of Klein and Spady (1993), which attains the semiparametric e$ciency b...

Computer Games Software deeply relies on physics simulations, which are particularly demanding to analyze because they manipulate a large amount of interleaving oating point variables. Therefore, this application domain is an interesting workbench to stress the trade-o between accuracy and e ciency of abstract domains for static analysis. In this paper, we introduce Parametric Hypercubes, a nov...

The implications of the propagation of uncertainty for the e ciency of stochastic water pollution control were analyzed. The empirical analysis focused on nitrogen pollution of the Baltic Sea from Swedish crop farms. A two moment model (mean and variance) of the distribution of coastal load was developed and integrated with an economic model of arable land-use choice. It was shown that uncertai...

The case described by Dr. Sarper and her colleagues in their letter to the editor, entitled “Severe iron defi ciency anemia due to late presentation of congenital diaphragmatic hernia in a toddler”, was not a late but rather a delayed diagnosis case since iron defi ciency anemia was diagnosed in this patient at least a year earlier with intermittent vomiting [1]. The diagnosis of a diaphragmati...
