基于作业成本法的供应商选择改进模型研究

随着供应链中各企业紧密联接的趋势越来越明显,传统的基于价格驱动的供应商竞争关系正在逐渐为同时关注整体竞争要素的战略供应商关系管理所取代。基于作业成本法的供应商选择和评价模型因能够较好地满足多因素评价的要求,而在供应商关系管理中突显出优势。在对现有作业成本法(ABC)基础上的供应商评价和选择方法回顾和分析的基础上,提出相应改进方向与模型。改进后的模型考虑到了企业和供应商长期合作过程中的各种因素的动态性,以便模型更能真实准确的反映影响供应商选择的各项成本,使得企业能做出更加准确的决策。

HIERARCHICAL CHOICE IN ECONOMICS

Abstract. The paper examines the relevance for economic issues of choice which is not characterized by unlimited substitutability. After showing that hierarchical choice is common in other social sciences like psychology, the paper proceeds with an examination of such choice and of its different categories. Subsequently the implications for hierarchical choice for specific economic issues are analysed. In particular, there is discussion and literature review of demand theory, Engel curves, the theory of the firm and social choice theory. Finally, some suggestions for the application to other economic problems are considered.     

Revealed preferences of individual players in sequential games

This paper studies rational choice behavior of a player in sequential games of perfect and complete information without an assumption that the other players who join the same games are rational. The model of individually rational choice is defined through a decomposition of the behavioral norm assumed in the subgame perfect equilibria, and we propose a set of axioms on collective choice behavior that characterize the individual rationality obtained as such. As the choice of subgame perfect equilibrium paths is a special case where all players involved in the choice environment are each individually rational, the paper offers testable characterizations of both individual rationality and collective rationality in sequential games.     

Minimal manipulability: Unanimity and nondictatorship

This paper is concerned with the number of profiles at which a nondictatorial social choice function is manipulable. For three or more alternatives the lower bound is found for unanimous social choice functions. In the case of three alternatives the lower bound is found for surjective social choice functions. In both cases all social choice functions reaching the lower bound are characterized for more than two agents. In the case of two agents the characterized social choice functions form a subset of the set of all social choice functions reaching the minimum.     

Generic impossibility of Arrow’s impossibility theorem

Our major objective is to show that if there are infinitely many alternatives and society can be decomposed into the sum of two non-negligible coalitions, the set of all Arrovian collective choice rules that satisfy the ultrafilter property (its set of decisive coalitions form an ultrafilter), is nowhere dense in the set of all Arrovian collective choice rules. This result entails that (1) almost all Arrovian collective choice rules are non-dictatorial and (2) in any neighborhood of a dictatorial Arrovian collective choice rule, a nondictatorial Arrovian collective choice rule can be found, i.e., the property of admitting a dictator is not a locally stable property for Arrovian collective choice rules in the sense that the property does not withstand a small perturbation.     

基于利益相关者理论的会计政策选择

本文认为,会计政策选择可以分为宏观和微观两个层次,无论是宏观会计政策选择还是微观会计政策选择,都是特定主体的行为过程。既然选择是一种行为,必然存在行为主体与客体,以及行为背后的动因和主体要达到的目标。本文在利益相关者理论下分别探讨了宏观会计政策选择和微观会计政策选择的主体、客体、动因以及目标。     

Diversification preferences in the theory of choice

Diversification represents the idea of choosing variety over uniformity. Within the theory of choice, desirability of diversification is axiomatized as preference for a convex combination of choices that are equivalently ranked. This corresponds to the notion of risk aversion when one assumes the von Neumann–Morgenstern expected utility model, but the equivalence fails to hold in other models. This paper analyzes axiomatizations of the concept of diversification and their relationship to the related notions of risk aversion and convex preferences within different choice theoretic models. Implications of these notions on portfolio choice are discussed. We cover model-independent diversification preferences, preferences within models of choice under risk, including expected utility theory and the more general rank-dependent expected utility theory, as well as models of choice under uncertainty axiomatized via Choquet expected utility theory. Remarks on interpretations of diversification preferences within models of behavioral choice are given in the conclusion.     

A note on individual choice models of migration

In this paper individual probabilistic choice models are developed for the decision to migrate and the choice among alternative destinations. The models are developed to investigate how characteristics of decision makers and of alternative destinations affect choice. Several migration models in the literature (e.g., mover-stayer models) are shown to be special cases, their behavioral assumptions are made explicit, and a framework for testing these assumptions is provided.     

Microeconometric models of tourists'' destination choice

The focus of this paper is on the microeconometric analysis of spatial choice in a cross section. Nested multinomial logit models are used to analyze the determinants of individual choice among destinations and vacation activities. Cramer and Ridder's likelihood ratio test for pooled alternatives in multinomial logit models is sequentially applied in order to determine the adequate aggregation level of the mutually exclusive alternatives in the choice set. The specification test suggested by Chesher and Santos Silva (1992) is used to investigate whether or not the IIA proposition is fulfilled within the assumed choice subsets.

How do respondents process stated choice experiments? Attribute consideration under varying information load

The popularity of stated choice (SC) experiments has produced many design strategies in which researchers use increasingly more ‘complex’ choice settings to study choice behaviour. When the amount of information to assess increases, we wonder how an individual handles such information in making a choice. Defining the amount of information as the number of attributes associated with each choice set, we investigate how this information is processed as we vary its ‘complexity’. Four ordered heterogeneous logit models are developed, each for an SC design based on a fixed number of attributes, in which the dependent variable defines the number of attributes that are ignored. We find that the degree to which individuals ignore attributes is influenced by the dimensionality of the SC experiment, the deviation of attribute levels from an experienced reference alternative, the use of ‘adding up’ attributes where feasible, the number of choice sets evaluated, and the personal income of the respondent. The empirical evidence supports the view that individuals appear to adopt a range of ‘coping’ strategies that are consistent with how they process information in real markets, and that aligning ‘choice complexity’ with the amount of information to process is potentially misleading. Relevancy is what matters. Copyright © 2006 John Wiley & Sons, Ltd.
