A SHORT PROOF FOR THE EXISTENCE OF HAAR MEASURE ON COMMUTATIVE HYPERGROUPS [PDF]

Journal of Sciences, Islamic Republic of Iran, 2002
In this short note, we have given a short proof for the existence of the Haar measure on commutative locally compact hypergroups based on functional analysis methods by using Markov-Kakutani fixed point theorem.

Stable matching in large markets with occupational choice

Theoretical Economics, Volume 19, Issue 3, Page 1261-1304, July 2024.
We introduce a model of large many‐to‐one matching markets with occupational choice where each individual can choose which side of the market to belong to. We show that stable matchings exist under mild assumptions; in particular, both complementarities and externalities can be accommodated.

On the solution of games with arbitrary payoffs: An application to an over‐the‐counter financial market

International Journal of Finance &Economics, Volume 29, Issue 2, Page 1877-1895, April 2024.
Abstract This paper defines a variety of game theoretic solution concepts in the language of soft set theory. We begin by defining the Nash equilibrium in pure strategies. We assume that the gains of the players are totally ordered and non‐desirable alternatives are absent. Moreover, we introduce the notions of strong and semi‐strong utility. These two

Promoting a reputation for quality

The RAND Journal of Economics, Volume 55, Issue 1, Page 112-139, Spring 2024.
Abstract I model a firm that invests in the quality of its product and influences how that quality is disclosed. The firm can promote its product; at random intervals it can disclose quality for a cost. At low reputations, promotion allows a firm to reestablish itself and the firm invests to take advantage of this.

On the Existence Result for System of Generalized Strong Vector Quasiequilibrium Problems

Fixed Point Theory and Applications, 2011
We introduce a new type of the system of generalized strong vector quasiequilibrium problems with set-valued mappings in real locally convex Hausdorff topological vector spaces.

Economies with rights: Efficiency and inequality

Journal of Public Economic Theory, Volume 26, Issue 1, February 2024.
Abstract We consider a scenario where inequality levels originate harmful effects on society. To alleviate this negative externality, we introduce tradable consumption licenses within a general equilibrium framework to obtain efficient outcomes, reduce inequality, and improve social welfare.

Generalization of Beckmann’s Transformation for Traffic Assignment Models with Asymmetric Cost Functions

Journal of Advanced Transportation, Volume 2024, Issue 1, 2024.
An optimization model is developed to solve the deterministic traffic assignment problem under congested transport networks with cost functions that have an asymmetric Jacobian. The proposed formulation is a generalization of Beckmann’s transformation that can incorporate network links with multivariate vector cost functions to capture the asymmetric ...

Existence Results for System of Variational Inequality Problems with Semimonotone Operators

Journal of Inequalities and Applications, 2010
We introduce the system of variational inequality problems for semimonotone operators in reflexive Banach space. Using the Kakutani-Fan-Glicksberg fixed point theorem, we obtain some existence results for system of variational inequality problems for ...

The random Kakutani fixed point theorem in random normed modules

Based on the recently developed theory of random sequential compactness, we prove the random Kakutani fixed point theorem in random normed modules: if G is a random sequentially compact L0-convex subset of a random normed module, then every -stable Tc-upper semicontinuous mapping F:G to 2G such that F(x) is closed and L0-convex for each x in G, has a ...
