Theoretical voting models predict convergence of two parties' trade policy platforms. In contrast, real-world observations reveal substantial differences in the platforms of competing parties. This paper modifies the standard probabilistic voting model in a way that allows for divergence of policy platforms. Two parties are shown to adopt different policy platforms if the impact of trade policy choices on expected election outcomes depends on the specific identity of the policy-promising party; that is, if the chance to win depends not only on what trade policy is promised but also on which party does the promising. 相似文献

There have been significant structural changes in research markets in recent years reflected in the increase in the number of academic journals. This paper uses a differential game model of authors and journal editors to examine the effects of an increase in competition among academic journals. Does an increase in the number of academic journals lead to an increase in scholarly articles published? Will an increase in publishing outlets adversely affect research quality? The results show greater competition does not affect research output and in fact enhances research quality. The number of journals and the relative discount rates of authors and editors are crucial determinants of the effects of competition. 相似文献

Consumer attitudes toward a proposed new public transportation system were assessed through the application of two multidimensional scaling models to data on preference choices for system attributes. Carroll's vector model and Kruskal and Carmone's nonmetric unfolding model were compared on theoretical and empirical levels to determine their utility for exposing the latent structure of attitudes for a public project. While the unfolding model was attractive because of a theoretical property, the vector model was able to uncover latent dimensions for the attitudes which could be related via discriminant analysis to socio-economic and demographic characteristics of the respondents. The vector model also produced an outcome which was more closely related to a unidimensional analysis of these data. Therefore, even though both the vector and unfolding models produced plausible geometric representations of the attitudes which arc expected to aid urban transportation planners in designing systems, the vector model produced the more acceptable outcome. 相似文献
