Some results on the existence of utility functions on path connected spaces

This paper concerns the existence of utility representations for preferences defined on a path connected space X. This includes any convex set. A classical result of Eilenberg (1941) proves the existence of utility representations when the consumption set is connected and separable. In an infinite dimensional space the above result may not be useful, because we lack, in general, the separability of the space. The non-separable spaces L^∞ and ca(K) are typical examples in mathematical economics. In this paper we show that a continuous preference relation ≽, on X has a continuous utility representation if and only if it is countably bounded, i.e., there is some countable subset F of X such that for all x in X there exist y and z in F with y≽x≽z. An easy corollary states that any continuous preference which has a best and a worst point has a continuous representation. We also obtain a convex continuous preference on a Banach lattice that has not a utility representation, because it is not countably bounded.

Abstract

Today, many public professionals feel estranged from the policy programmes they implement; that is, they experience ‘policy alienation’. This is of concern as, for satisfactory implementation, some identification with the policy is required. We conceptualize policy alienation based on the sociological concept of work alienation, and show how this can be used in policy implementation research. Studying a Dutch case of professionals implementing a new work disability decree, we observe how NPM practices increase policy alienation because of a perceived dysfunctional focus on efficiency and results. A large number of policy changes and stricter implementation rules further increased policy alienation.     

中国传统文化对民营企业管理的影响机制研究

近年来,随着我国经济的不断发展,大量外企进驻中国,它们以"合作方"的身份大量收购我国民营企业,由于我国民营企业的家族式管理的滞后性导致我国民营企业成为了外企的"代言人"。所以本文基于中国传统文化的视角,深入剖析传统文化对民企的管理模式、管理战略、执行力度的影响,由此展开中国传统文化对中国民营企业管理的作用机制研究,使得民营企业能正确认识我国的传统文化的同时,将一些符合其企业环境的文化应用到企业内部管理中,让民企成为我国文化的"代言人"。     

Recent evidence on the impact of government budget deficits on the ex ante real interest rate yield on Moody’s Baa-rated corporate bonds

This study provides recent empirical evidence on the impact of the federal budget deficit on the ex ante real interest rate yield on Moody’s Baa-rated corporate bonds. The study is couched within an open loanable funds model that includes the ex ante real short term real interest rate, the M1 money supply, net international capital inflows, and the unemployment rate. Using quarterly data for the period 1973.1–2007.4, two-stage least squares estimation reveals that the federal budget deficit, expressed as a percent of GDP, exercised a positive and statistically significant impact on the ex ante real interest rate yield on these corporate issues.     

Semiparametric bounds on treatment effects

We present a variety of semiparametric models that produce bounds on the average causal effect of a binary treatment on a binary outcome. The semiparametric assumptions exploit variation in observable covariates to narrow the bounds. In our main model, the outcome is determined by a generalized linear model, but the treatment may be arbitrarily endogenous. Our bounding strategy does not require the existence of an instrument, but incorporating an instrument narrows the bounds. The bounds are further improved by combining the semiparametric model with the joint threshold-crossing assumption of Shaikh and Vytlacil (2005).

基于刺激-机体-响应（SOR）理论的推荐者社交网站效果研究

推荐者社交网站在提升消费者购买转换率方面起到了显著的作用。本文基于刺激-机体-响应（Stimulus—Organism—Response,S—O—R）理论模型,从消费者愉悦及唤醒两个方面,构建了推荐者社交网站影响消费者购买意向的概念模型,以揭示推荐者社交网站的作用机理。研究采用问卷调查的方法,研究表明,愉悦和唤醒均对消费者购买意向产生显著的正向作用;信息丰富度、客制化、视觉性对愉悦及唤醒分别产生显著作用,其中信息丰富化对唤醒产生了负向影响作用;经济性对愉悦产生了显著的正向作用,而对唤醒未产生显著作用。     

Homothetic preferences on star-shaped sets

This paper describes properties of homothetic preferences on a subset X of a vector space which is star-shaped with respect to 0 (e.g., a cone). We prove that a preference relation on X is homothetic, greedy and calibrated if and only if there exists a positively homogeneous function that represents it. This function is unique up to a strictly increasing and positively homogeneous transformation. As a corollary, we find that, if X is contained in a topological vector space, then œ is homothetic and continuous if and only if there exists a positively homogeneous and continuous function that represents it.     

Inducing relations on incomplete ordinal data

Let X denote a set of n elements or stimuli which have an underlying linear ranking L based on some attribute of comparison. Incomplete ordinal data is known about L, in the form of a partial order P on X. This study considers methods which attempt to induce, or reconstruct, L based only on the ordinal information in P. Two basic methods for approaching this problem are the cardinal and sequel construction methods. Exact values are computed for the expected error of weak order approximations of L from the cardinal and sequel construction methods. Results involving interval orders and semiorders for P are also considered. Previous simulation comparisons for cardinal and sequel construction methods on interval orders were found to depend on the specific model that was used to generate random interval orders, and were not found to hold for interval orders in general. Finally, we consider the likelihood that any particular linear extension of P is the underlying L.     

Non-cooperative games on hyperfinite Loeb spaces

We present a particular class of measure spaces, hyperfinite Loeb spaces, as a model of situations where individual players are strategically negligible, as in large non-anonymous games, or where information is diffused, as in games with imperfect information. We present results on the existence of Nash equilibria in both kinds of games. Our results cover the case when the action sets are taken to be the unit interval, results now known to be false when they are based on more familiar measure spaces such as the Lebesgue unit interval. We also emphasize three criteria for the modelling of such game-theoretic situations—asymptotic implementability, homogeneity and measurability—and argue for games on hyperfinite Loeb spaces on the basis of these criteria. In particular, we show through explicit examples that a sequence of finite games with an increasing number of players or sample points cannot always be represented by a limit game on a Lebesgue space, and even when it can be so represented, the limit of an existing approximate equilibrium may disappear in the limit game. Thus, games on hyperfinite Loeb spaces constitute the ‘right' model even if one is primarily interested in capturing the asymptotic nature of large but finite game-theoretic phenomena.
