We axiomatize preferences that can be represented by a monotonic aggregation of subjective expected utilities generated by a utility function and some set of i.i.d. probability measures over a product state space, S1. For such preferences, we define relevant measures, show that they are treated...

This paper investigates the factors that shaped Kenyan's voting intentions in the 2007 presidential election.  Using data from a public opinion survey conducted two weeks before the election we are able to evaluate the relative importance of what shaped voting behavior comprehensively, taking...

We provide a simple necessary and sufficient condition for when a multiproduct demand system can be generated from a discrete choice model with unit demands.

A theory of decision making is proposed that supplies an axiomatic basis for the concept of satisficing postulated by Herbert Simon. After a detailed review of classical results that characterize several varieties of preference-maximizing choice behavior, the axiomatization proceeds by weakening...

The paper uses an appropriate survey from rural China to answer the question: Is happiness infectious, i.e. does the happiness of an individual depend positively on the happiness of their reference group?  The evidence is consistent with this hypothesis, but the challenge is to solve the...

In the workhorse  model of welfare economics, the elasticity of marginal utility, often denoted as η, serves simultaneously to represent aversion to risk, aversion to spatial inequality, and preferences for intertemporal substitution.  While Kreps-Porteus-Selden and Epstein-Zin preferences...

The exchange between Epstein (2010) and Klibanoff et al. (2012) identified a behavioral issue that sharply distinguishes between two classes of models of ambiguity sensitivity, exemplified by the Î±-MEU model and the smooth ambiguity model, respectively. The issue in question is whether a...

Drawing on the so-called `doctrinal paradox`, List and Pettit (2002a) have shown that, given an unrestricted domain condition, there exists no procedure for aggregating individual sets of judgments over multiple interconnected propositions into corresponding collective ones, where the procedure...

It is received financial wisdom that when there is free entry by speculators, it is impossible to generate net profits on publicly available information. In this paper we study a version of the standard Kyle (85) model with endogenous information acquisition and we find that equilibria exist...
