The main purpose of this paper is to develop a method and an algorithm for the aggregation as well as disaggregation of n-way tables, thereby minimizing a set of suitable criteria. One should observe that there is no real difference between aggregation and disaggregation when using this method. Here are presented some basic facts about a mainly one-dimensional method and an outline showing how the method may be extended to more complex cases. 相似文献

In this article, the beginnings of a new approach to the theory of aggregation are developed. The basic idea is that aggregation should involve two things: (a) data over which social preferences are defined should be mapped into a smaller-dimensional space, and (b) there should exist an ordering on that lower-dimensional space such that an improvement in this criterion implies an improvement for any of a class of social preference functions and of a class of individual preference relations defined over the original space. Results are developed which show that this conception of aggregation can yield meaningful results; particularly with respect to comparisons of ‘real national income’ in two situations, for a given economy. 相似文献

This paper examines the aggregation of preferences with a finitely additive measure space of agents. We consider three types of non-dictatorship axioms: non-dictatorship, coalitional non-dictatorship, and atomic non-dictatorship. First, we show that the existence of an atom is a necessary and sufficient condition for the existence of a social welfare function that satisfies weak Pareto, independence of irrelevant alternatives, and coalitional non-dictatorship. Second, we simultaneously impose non-dictatorship and coalitional non-dictatorship, and specify a necessary and sufficient condition for the finitely additive measure that guarantees the compatibility among the axioms. Third, we impose all non-dictatorship axioms and show that the corresponding measure is extremely restricted. 相似文献

Names are important. Being remembered by name is universally appreciated and associated with respect. Thus, correct use of names and titles can be extremely advantageous in relationships. This is particularly true in the health care setting. 相似文献

We investigate the structure of fuzzy aggregation rules which, for every permissible profile of fuzzy individual preferences, specify a fuzzy social preference. We show that all fuzzy aggregation rules which are strategy-proof and satisfy a minimal range condition are dictatorial. In other words, there is an individual whose fuzzy preferences determine the entire fuzzy social ranking at every profile in the domain of the aggregation rule. To prove this theorem, we show that all fuzzy aggregation rules which are strategy-proof and satisfy the minimal range condition must also satisfy counterparts of independence of irrelevant alternatives and the Pareto criterion. There has been hardly any treatment of the manipulability problem in the literature on social choice with fuzzy preferences. 相似文献

It is shown that discontinuities of the individual demand pattern due to non-convex preferences are smoothed out by aggregation, if the distribution of the demand characteristics is ‘suitably diffused’. 相似文献

This paper develops an analytical framework tointegrate static and dynamic effects of theoreticallyrelevant and practically applied investment-decisioncriteria on the marginal rate of substitution betweeninvestment and labour. The new propositions are relatedto the ranking of relative present value, Kalecki'sindex of efficiency and the static version ofrecoupment period criteria. Investors in post-communisteconomies have switched from the recoupment period tothe criteria based on discounting. This is aninstitutional change typical for these economies. Itimplies a choice of techniques with lower investmentintensity, which is best supported by government'spolicy to promote labour mobility. 相似文献

Aggregation is commonly associated with loss of information. In contrast, this paper shows that aggregation can actually enhance information down‐the‐road by deterring information cascades. In particular, when hierarchical tiers forward only aggregate recommendations rather than nitty‐gritty details, it increases the uncertainty faced by subsequent tiers. This makes individuals at higher levels more willing to rely on and convey their own views rather than simply rubber stamping suggestions from lower levels.

In this paper, we consider temporal aggregation of volatility models. We introduce semiparametric volatility models, termed square-root stochastic autoregressive volatility (SR-SARV), which are characterized by autoregressive dynamics of the stochastic variance. Our class encompasses the usual GARCH models and various asymmetric GARCH models. Moreover, our stochastic volatility models are characterized by multiperiod conditional moment restrictions in terms of observables. The SR-SARV class is a natural extension of the class of weak GARCH models. This extension has four advantages: (i) we do not assume that fourth moments are finite; (ii) we allow for asymmetries (skewness, leverage effect) that are excluded from weak GARCH models; (iii) we derive conditional moment restrictions and (iv) our framework allows us to study temporal aggregation of IGARCH models. 相似文献
