Comparison-concave utility and following behaviour in social and economic settings
نویسندگان
چکیده
This paper describes a theory of rational emulation and deviance. It assumes that individuals care about relative position (or ‘status’), and constructs a model of decisionmaking in social and economic settings. The analysis shows why individuals who want to be different from others will, paradoxically, find it rational to imitate other people. The paper also provides a choice-theoretic foundation for a number of ideas in the social psychology and economics literatures. The central point of the paper is that concern about relative position or rank is, by itself, insufficient to bring about emulation. The reaction of an individual to others’ behaviour depends crucially on the curvature of the comparison term in their utility function: individuals with comparison-concave utility follow others while those with comparison-convex utility act deviantly. 1998 Elsevier Science S.A.

Revealed preference analysis for convex rationalizations on nonlinear budget sets
We present necessary and sufficient revealed preference conditions to verify whether a nite data set on nonlinear budget sets is consistent with the maximization of a quasi–concave utility function. Our results can be used to test for convexity of the underlying preference relation. We also show that inmany settings, our conditions are easy to use in practical applications.
متن کاملAnalysis of the Utility of Economic Sectors in Achieving Agricultural Development: Applying an Analytic Hierarchy Process
ABSTRACT- According to article 44 of the I.R. of Iran Constitution, the Iranian economy consists of three sectors; the state, the cooperative, and the private sectors. The aim of this study was to present a hierarchy of criteria for selecting the best economic sector for agricultural development. Analytic Hierarchy Process (AHP) was used to calculate the relative importance of either criteria o...
متن کاملThe Continued Utility and Viability of Dakin’s Solution in Both High- and Low-resource Settings
Healthcare is expensive and often inaccessible to many. As a result, surgeons must consider simple, less expensiveinterventions when possible. For wound care, an older but quite effective cleaning agent is Dakin’s solution (0.5%sodium hypochlorite), an easily made mixture of 100 milliliters (ml) bleach with 8 teaspoons (tsp) baking soda into agallon of clean water or 25 ml ble...
متن کاملWhen Do We Feel Sorry for Others? : An Externality of Lake Use as an Example
The purpose of the study was to verify, through the use of an experimental method, the assumption that the ‘economic human’ pays more attention to the externality he/she causes as the strength of externality increases. We used a social-experiment design within an undergraduate classroom to test assumptions, using statistical method. A lakeside plant was used as an example. Our results confirmed...
متن کاملDimensional behaviour of entropy and information
We develop an information-theoretic perspective on some questions in convex geometry, providing for instance a new equipartition property for log-concave probability measures, some Gaussian comparison results for log-concave measures, an entropic formulation of the hyperplane conjecture, and a new reverse entropy power inequality for log-concave measures analogous to V. Milman’s reverse Brunn-M...
