We prove a representation theorem for preference relations over countably infinite lotteries that satisfy a generalized form of the Independence axiom, without assuming Continuity. The representing space consists of lexicographically ordered transfinite sequences of bounded real numbers. This result is generalized to preference orders on abstract superconvex spaces.  相似文献

We focus on the Bicentenary (1913) celebrations, organised in St. Petersburg, Russia, by the great probabilist, A. A. Markov, founder of the theory of Markov chains. This theory was stimulated by the need to demonstrate a Law of Large Numbers for sums of dependent random variables. Markov's work on the Law of Large Numbers originating in the celebrations was exposited and extended by S. N. Bernstein and, in English, by J. V. Uspensky, who had played an integral part in the St. Petersburg celebrations. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

The analysis of urban walkability has been extensively explored in the last decades. Despite this growing attention, there is a lack of studies attentive on how citizens' values, individual abilities and urban environment favour or hinder the propensity to walk. Hence, there is a need to explore how preferences and values of citizens vary in space in order to design walkability policies able to improve the capability set of citizens. In this perspective, the design of spatial decision tools aimed to plann public policies for the development of walkable cities needs further investigation. We propose a Multiple Criteria Decision Analysis (MCDA) method aimed to elaborate walkability decision maps for different groups of citizens that reflect their capability to walk in the urban environment. We tested the method in the city of Alghero (Italy). First, we analysed walkability under a normative model named CAWS; then we made a survey with 358 participants in order to study the driving values that influence their choice to walk and finalised to build an evaluation model attentive to individual differences. Cluster analysis was employed to group citizens into 11 groups based on their sociodemographic characteristics and preferences on spatial criteria of walkability. Finally, by integrating GIS with MCDA we built a set of decision maps representative of the walkability of the 11 groups of citizens. Results highlight the importance of citizens’ values for policy design, allow the interpersonal comparison among individuals and group preferences and give new suggestions for the formulation of walkability oriented urban policies. Moreover, the results confirm the usability of the general method as a decision support tool supporting the design of urban policies.  相似文献

In 1951 R. A. Fisher described what had been achieved in the 20th century so far: “we have learnt (i) To conserve in its statistical reduction the scientific information latent in any body of observations. (ii) To conduct experimental and observational inquiries so as to maximise the information obtained for a given expenditure.” This paper asks what Fisher meant and, in particular, how he saw his work on experimental design as contributing to the objective of maximizing information for a given expenditure. The material examined ranges from detailed work on issues like “the information lost in measurement of error” to polemics against decision theory .  相似文献

This paper deals with the problem of allocating additional resources in a public university system. Instead of a solution imposed from above, the proposed bargaining approach lets the universities voluntarily agree on a solution that benefits them all. To be realistic the allocation assumes that the universities will keep their current technical efficiency. A bargaining problem is formulated, defining the corresponding feasible set and disagreement point. Four different bargaining solutions, namely Nash, Kalai-Smorodinsky, Egalitarian and Utilitarian, are considered and discussed. The proposed approach is applied to a real-world dataset involving the nine public universities of the Andalusian region. The results of the different bargaining solutions are very consistent as regards the output and utility improvements to be achieved by each university.  相似文献

For many years experimental observations have raised questions about the rationality of economic agents—for example, the Allais Paradox or the Equity Premium Puzzle. The problem is a narrow notion of rationality that disregards fear. This article extends the notion of rationality with new axioms of choice under uncertainty and the decision criteria they imply (Chichilnisky, G., 1996a. An axiomatic approach to sustainable development. Social Choice andWelfare 13, 257–321; Chichilnisky, G., 2000. An axiomatic approach to choice under uncertainty with Catastrophic risks. Resource and Energy Economics; Chichilnisky, G., 2002. Catastrophical Risk. Encyclopedia of Environmetrics, vol. 1. John Wiley & Sons, Ltd., Chicester). In the absence of catastrophes, the old and the new approach coincide, and both lead to standard expected utility. A sharp difference emerges when facing rare events with important consequences, or catastrophes. Theorem 1 establishes that a classic axiom of choice under uncertainty – Arrow’s Monotone Continuity axiom, or its relatives introduced by DeGroot, Villegas, Hernstein and Milnor – postulate rational behavior that is ‘insensitive’ to rare events as defined in (Chichilnisky, G., 1996a. An axiomatic approach to sustainable development. Social Choice andWelfare 13, 257–321; Chichilnisky, G., 2000. An axiomatic approach to choice under uncertainty with Catastrophic risks. Resource and Energy Economics; Chichilnisky, G., 2002. Catastrophical Risk. Encyclopedia of Environmetrics, vol. 1. John Wiley & Sons, Ltd., Chicester). Theorem 2 replaces this axiom with another that allows extreme responses to extreme events, and characterizes the implied decision criteria as a combination of expected utility with extremal responses. Theorems 1 and 2 offer a new understanding of rationality consistent with previously unexplained observations about decisions involving rare and catastrophic events, decisions involving fear, the Equity Premium Puzzle, ‘jump diffusion’ processes and ‘heavy tails’, and it agrees with (Debreu, G., 1953. Valuation equilibrium and Pareto optimum. Proceedings of the National Academy of Sciences, 40, 588–592) formulation of market behavior and his proof of Adam Smith’s Invisible Hand theorem.  相似文献

Bayesian experimental design is a fast growing area of research with many real‐world applications. As computational power has increased over the years, so has the development of simulation‐based design methods, which involve a number of algorithms, such as Markov chain Monte Carlo, sequential Monte Carlo and approximate Bayes methods, facilitating more complex design problems to be solved. The Bayesian framework provides a unified approach for incorporating prior information and/or uncertainties regarding the statistical model with a utility function which describes the experimental aims. In this paper, we provide a general overview on the concepts involved in Bayesian experimental design, and focus on describing some of the more commonly used Bayesian utility functions and methods for their estimation, as well as a number of algorithms that are used to search over the design space to find the Bayesian optimal design. We also discuss other computational strategies for further research in Bayesian optimal design.  相似文献

The current hype about culture‐led local development models is causing an increasing interest in cultural policies in the broader context of urban policy. This is not necessarily a transitory situation bound to fade once the hype is over. Under certain conditions, there is room to believe that culture may indeed become a main development driver of urban systems. For this to happen, however, it is necessary to abandon simple mono‐causal developmental schemes (such as the ‘creative class’ model) and look for more articulated approaches. This calls in turn for a complex systems‐based conceptual framework that is at the same time rich enough to capture the complexity of the interdependences among policy and state variables, and manageable enough to be of practical use, not only for policy design professionals but also for local stakeholders who want to take part in collective decision‐making processes. Inclusiveness and collective decision making are almost unavoidable in the case of cultural planning strategies, as the social sustainability of culture‐based value creation processes crucially depends on boosting the level of access to cultural opportunities by local residents. In this article we present an approach that may be a tentative first step in this direction.  相似文献
