Kantian Optimization : An Approach to Cooperative Behavior

Roemer, John E. - 2013

species, the reigning assumption in economic theory is that individuals optimize in an autarkic manner (as in Nash and …

Convex Covers of Symmetric Games

Rulnick, John M.; Shapley, Lloyd S. - 1998

We consider a multi-player, cooperative, transferable-utility, symmetric game (N,v) and associated convex covers, i.e., convex games (N,w) such that w is greater than or equal to v. A convex cover w is efficient iff w(0) equals v(0) and w(N) equals v(N); and minimal iff there is no convex cover...

Set-weighted games and their application to the cover problem

Gusev, Vasily - 2021

The cover of a transport, social, or communication network is a computationally complex problem. To deal with it, this paper introduces a special class of simple games in which the set of minimal winning coalitions coincides with the set of least covers. A distinctive feature of such a game is...

Common Mistakes in Computing the Nucleolus

Guajardo, Mario; Jörnsten, Kurt O. - 2014

Despite linear programming and duality have correctly been incorporated in algorithms to compute the nucleolus, we have found mistakes in how these have been used in a broad range of applications. Overlooking the fact that a linear program can have multiple optimal solutions and neglecting the...

Measuring the power of nodes in digraphs

Herings, Peter Jean-Jacques; Laan, Gerard van der; … - 2001

Many economic and social situations can be represented by a digraph. Both axiomatic and iterativemethods to determine the strength or power of all the nodes in a digraph have been proposed inthe literature. We propose a new method, where the power of a node is determined by both thenumber of its...

Optimal Multiattribute Screening

Weber, Thomas A. - 2016

We provide a technique for constructing optimal multiattribute screening contracts in a general setting with one-dimensional types based on necessary optimality conditions. Our approach allows for type-dependent participation constraints and arbitrary risk profiles. As an example we discuss...

Chapter 11. Computing All Solutions to Polynomial Equations in Economics

Kubler, Felix; Renner, Philipp; Schmedders, Karl - In: Handbook of computational economics : volume 3, (pp. 599-652). 2014

Multiplicity of equilibria is a common problem in many economic models. In general, it is impossible to devise methods that always find all equilibria for any type of model. A notable exception are models in which all equilibria are solutions to a system of polynomial equations since there are...

Modeling strategic investment decisions in spatial markets

Lorenczik, Stefan; Malischek, Raimund; Trüby, Johannes - 2014

Markets for natural resources and commodities are often oligopolistic. In these markets, production capacities are key for strategic interaction between the oligopolists. We analyze how different market structures influence oligopolistic capacity investments and thereby affect supply, prices and...
