A linear utility model is introduced for optimal selection when several subpopulations of applicants are to be distinguished. Using this model, procedures are described for obtaining optimal cutting scores in subpopulations in quota-free as well as quota-restricted selection situations. The cutting scores are optimal in the sense that they maximize the overall expected utility of the selection ...

We investigate systems of indirect voting based on the law of Penrose, in which each representative in the voting body receives the number of votes (voting weight) proportional to the square root of the population he or she represents. For a generic population distribution the quota required for the qualified majority can be set in such a way that the voting power of any state is proportional t...

We study the possibilities for agenda manipulation under strategic voting for two prominent sequential voting procedures, the amendment and the successive procedure. We show that a well-known result for tournaments, namely that the successive procedure is (weakly) more manipulable than the amendment procedure at any given preference profile, extends to arbitrary majority quotas. Moreover, our c...

Using numerical simulations of the mixed common sardine and anchovy fishery of central-southern Chile, this article studies the effects of the distribution of administrative costs between the government and the fishing industry in an individual transferable quota system. Consistent with recent theoretical results, the analysis indicates that the presence and distribution of the administrative c...

In a homogeneous jury, in which each vote is correct with the same probability, and each pair of votes correlates with the same correlation coefficient, there exists a correlation-robust voting quota, such that the probability of a correct verdict is independent of the correlation coefficient. For positive correlation, an increase in the correlation coefficient decreases the probability of a co...

The wreckfish individual transferable quota (ITQ) program started in 1992 and is the oldest finfish ITQ program in the United States. Initially, the program appeared to be a success, bringing order to the previous years’ derbies. Ex-vessel prices rose, harvest stabilized, and there was an orderly shrinking of the fleet to an economically appropriate size. The subsequent history of the fishery i...
