The paper examines under what conditions vertically differentiated duopolists engage in first-degree price discrimination. Each firm decides on a pricing regime at a first stage and sets prices at a second stage. The paper shows that when unit cost is an increasing and convex function of...

This paper explores the implications of using multidimensional majorization criteria to derive inequality measures, without taking into consideration the idea behind the Pigou-Dalton principle, in the sense that if a richer person transfers something of at least one attribute to a poorer person...

This paper introduces two-player bargaining problems allowing for asymmetric subjective uncertainty about factors that determine whether agreement is achieved, focusing on surprising events, i.e. events believed possible by only one player. A `subjective Nash' solution is proposed, in which a...

In this paper we introduce product demand uncertainty in a mixed oligopoly model and reexamine the nature of sub-game perfect Nash equilibrium (SPNE) when firms decide in the first stage whether to lead or follow in the subsequent quantity-setting game. In the non-stochastic setting, Pal (1998)...

We consider the risk premium demanded by a decision maker in order to be indifferent between obtaining a new level of wealth with certainty, or to participate in a lottery which either results in unchanged wealth or an even higher level than what can be obtained with certainty. We study...

This paper considers ordered vector spaces with arbitrary closed cones and establishes a number of characterization results with applications to monotone comparative statics (Topkis (1978), Topkis (1998), Milgrom and Shannon (1994)). By appealing to the fundamental theorem of calculus for the...

In this paper, we study a two-period pure exchange economy with idiosyncratic uncertainty, moral hazard and multiple consumption goods. We consider two different market structures: contingent commodity markets on the one hand, and financial plus spot commodity markets on the other hand. We...

By combining a theory of herding behavior with the phenomenon of availability heuristic, this paper shows that non-informative advertisements can affect people's choices by influencing their perception of product quality. We present a model in which people can learn about product quality by...

The paper studies agents' general or specific investment decisions under different ownership structures in a thin, decentralized market where each agent's decision affects the decisions and welfare of other agents mainly through indirect market linkages. It focuses on the roles of both...

This paper presents a model of opportunistic behaviour in decentralized economic exchange and considers the impact of inadequate institutional framework of formal contract enforcement on economic performance. It is shown that (i) when the number of cheating traders is sufficiently large,...
