The constant elasticity of substitution (CES) function is widely used to model distributional preferences in modified dictator games. However, it has been pointed out that its parameter interpretations are inconsistent and problematic in applications. We constructed a model to address this issue...

In previous work, we proposed a method to address mathematical inconvenience by extending the constant elasticity of substitution (CES) utility function in Inukai, Shimodaira, and Shiozawa (2022, ISER DP No.1195). However, the relationships between the extended CES parameters and the external...

By taking sets of utility functions as a primitive description of agents, we define an ordering over assumptions on utility functions that gauges their implicit measurement requirements. Cardinal and ordinal assumptions constitute two types of measurement requirements, but several standard...

This paper proposes a geometric delineation of distributional preference types and a non-parametric approach for their identification in a two-person context. It starts with a small set of assumptions on preferences and shows that this set (i) naturally results in a taxonomy of distributional...

In his article 'The Case for a Multiple Utility Function' (Economics and Philosophy, 2, 159-83), Etzioni took the view that moral acts are qualitatively different from acts aimed at the satisfaction of desires. He introduced moral preferences and argued that these cannot be traded off against...

We provide a framework to decompose preferences into a notion of distributive justice and a selfishness part and to recover individual notions of distributive justice from data collected in appropriately designed experiments. “Dictator games” with varying transfer rates used in Andreoni and...

We report a laboratory experiment that enables us to distinguish preferences for altruism (concerning tradeoffs between own payoffs and the payoffs of others) from social preferences (concerning tradeoffs between the payoffs of others). By using graphical representations of three-person Dictator...

How far can we go in weakening the assumptions of the general equilibrium model? Existence of equilibrium, structural stability and finiteness of equilibria of regular economies, genericity of regular economies and an index formula for the equilibria of regular economies have been known not to...

In this paper we are concerned with the following question. Given an extended preference ordering under what conditions does there exist an empirical stochastic/social choice function which generates it? We use Farkas' lemma to obtain a necessary and sufficient condition under which such a...
