An experiment on coordination in multi-candidate elections: The importance of polls and election histories 总被引:2,自引:0,他引:2

Do polls simply measure intended voter behavior or can they affect it and, thus, change election outcomes? Do candidate ballot positions or the results of previous elections affect voter behavior? We conduct several series of experimental, three-candidate elections and use the data to provide answers to these questions. In these elections, we pay subjects conditionally on election outcomes to create electorates with publicly known preferences. A majority (but less than two-thirds) of the voters are split in their preferences between two similar candidates, while a minority (but plurality) favor a third, dissimilar candidate. If all voters voted sincerely, the third candidate — a Condorcet loser — would win the elections. We find that pre-election polls significantly reduce the frequency with which the Condorcet loser wins. Further, the winning candidate is usually the majority candidate who is listed first on the poll and election ballots. The evidence also shows that a shared history enables majority voters to coordinate on one of their favored candidates in sequences of identical elections. With polls, majority-preferred candidates often alternate as election winners. 相似文献

This article reports the development of a scale for evaluating family therapist skills. The scale includes ten items within each of five skill categories. All items were found to discriminate significantly between videotaped segments of effective and ineffective family therapist skills. Also all skill categories discriminated significantly between experienced and inexperienced family therapists. The interrater reliability and internal consistency of the categories were also judged to be acceptable. Suggestions are presented for uses of the scale in therapist training research. 相似文献

A Road Oft Taken: Unaffordable Home Energy Bills,Forced Mobility And Childhood Education in Missouri
Roger D. Colton 《Journal of Children and Poverty》1996,2(2):23-39
This study explores the interconnection between two seemingly unrelated problems: unaffordable home energy bills and poor educational attainment. The study goes beyond the self-evident observation that if hungry children make bad students, cold children would make bad students as well. Instead, the study focuses on the well-documented relationship between frequent household mobility and poor educational attainment. Looking specifically at a group of low-income households in Missouri, the study evaluates to what extent, if at all, unaffordable home energy bills contribute to frequent household mobility and, therefore, by extension, to the educational problems facing students in those households. 相似文献

Subjective expected utility maximization is derived from four axioms, using an argument based on the separating hyperplane theorem. It is also shown that the first three of these axioms imply a more general maximization formula, involving an evaluation function, which can still serve as a basis for decision analysis. 相似文献

Research on satisfaction with community services has used both age and life cycle stage as predictors of satisfaction. As both age and life cycle stage are indicators of life course, their relative advantages in service satisfaction research need to be assessed. The authors correlated both age and life cycle stage with twenty service satisfaction items and with item non-response (a measure of the salience of a service). Results were: (1) associations with service satisfaction were linear, (2) some associations with salience were markedly curvilinear, and (3) as predictors of service satisfaction, age and life cycle performed similarly. The choice between age and life cycle as predictors of service satisfaction appears to involve conceptual as well as empirical issues. 相似文献

The multiplicity technique has been proposed (Sirken, 1970) as a means of improving estimates of the number of rare “events” in a population. This paper describes one use of this technique, namely estimation of the number of persons with certain types of disability living in private dwellings in Canberra. The results are taken from three household surveys conducted in Canberra during 1978–79 in which a multiplicity rule linking parents, siblings and children of residents of sample households who were also living in private dwellings in Canberra was used. While no direct evidence on the level of non-sampling error is available here, it appears that net response errors at least are not substantial using this multiplicity rule and that a reasonable gain in sampling efficiency results from the use of multiplicity. 相似文献
