We consider rules that choose a location on a graph (e.g. a road network) based on agents' single-peaked preferences. First, we characterize the class of strategy-proof, onto rules when the graph is a tree. Such a rule is based on a collection of generalized median voter rules (Moulin, 1980) satisfying a consistency condition. Second, we characterize such rules for graphs containing cycles. We show that while such a rule is not necessarily dictatorial, the existence of a cycle grants some agent an amount of decisive power, unlike the case of trees. Rules for this case can be described in terms of a subclass of such rules for trees. Journal of Economic Literature Classification Numbers: C72, D78. 相似文献

Recently, applications of cooperative game theory to economic allocation problems have gained popularity. We investigate a
class of cooperative games that generalizes some economic applications with a similar structure. These are the so-called line-graph
games being cooperative TU-games in which the players are linearly ordered. Examples of situations that can be modeled like
this are sequencing situations and water distribution problems. We define four properties with respect to deleting edges that
each selects a unique component efficient solution on the class of line-graph games. We interpret these solutions and properties
in terms of dividend distributions, and apply them to economic situations.

本文提出了一个最小地扩充任意无向连通图为 R 边连通图的有效算法RMA。该算法采用了“先满足必要条件,再满足充要条件”的指导思想。对于一个任意无向连通图,首先将图中各点扩充到它所要求的最小度,然后检查它是否满足充要条件,如果不满足,则将该图分解,再根据最优程则,增加扩充边。将图合并,最后进行可行删除,解雇增广点,得到一个最小 R 边连通图。 相似文献

The Graph Model for Conflict Resolution is a flexible methodology for systematically studying strategic conflicts in the real world, and is therefore a natural tool for negotiation support. The basic definitions underlying the graph model are reviewed, and the techniques for analysis and interpretation are discussed. The modeling and analysis of a case study, an international trade negotiation concerning the export of Canadian softwood lumber to the United States, are used to demonstrate the practical application of the Graph Model for Conflict Resolution as a negotiation support tool. The modeling and analysis is carried out using the GMCR software system. The ability of the Graph Model for Conflict Resolution to provide insights and advice to negotiators is emphasized. 相似文献

An ‘innovative activity matrix’ is established from a recent ISTAT/CNR survey of innovation. After specifying the particularities of an innovative activity matrix in comparison with other flow matrices, we show that it is asymmetrical and clustered in parts of economic space. The structure of the innovative activity matrix is similar to that of the domestic and import requirement but not the capital flow matrix. Strong correlations indicate the following: that input–output analysis is useful for identifying the location of innovative activities in economic space; that it can be analyzed in an economically meaningful way; that its location is structured; and that, furthermore, it is structured in ways which are statistically related to economic activity. The paper ends with suggestions for the examination of possible causal relationships. 相似文献

In this paper, the maximum determinant of the associated 0-1 matrix in D-Optimal saturated main effect plans for 3× s_2 ×
s_3 factorials, is derived by the use of Graph theory and Combinatorics. The present work is related to a problem suggested
by Chatterjee and Narasimhan (2002). Using the theoretical results, we also give the designs for s3≥s2 + 1.

Given the growing debate concerning the use of alternative presentation formats in corporate financial reporting, Volmer's recent paper in this journal is to be welcomed (June, 1992). Volmer conducts an experiment which compares students' perceptions of graphical and numerical presentations of financial information. From this he concludes that (i) graphical presentations improve the communication of financial information, and (ii) the integration of accounting research and teaching constitutes an effective alternative teaching method. We agree with the general message of Volmer's paper, and hope that subsequent studies will build on his exploratory work. This comment suggests a number of areas for future developments. These concern the literature base, experimental design, corporate practice and educational implications. 相似文献
