Consensus-halving via theorems of Borsuk-Ulam and Tucker
Simmons, Forest W.; Su, Francis Edward - 2001 - Manuscript version, February 2001
In this paper we show how theorems of Borsuk-Ulam and Tucker can be used to construct a consensus-halving: a division of an object into two portions so that each of n people believe the portions are equally split. Moreover, the division takes at most n cuts, which is best possible. This extends...

Adverse selection in the annuity market when payoffs vary over the time of retirement
Brunner, Johann K.; Pech, Susanne - 2000 - Revised Version
This paper investigates the effect of adverse selection and price competition on the private annuity market in a model with two retirement periods. In this framework annuity companies can offer contracts with different payoffs over the periods of retirement. Varying the time structure of the...

Stackelberg Differential Game for Insurance Under Model Ambiguity
Cao, Jingyi; Li, Dongchen; Young, V.R; Zou, Bin - 2022
We study a dynamic Stackelberg differential game between a buyer and a seller of insurance policies in a spectrally negative Lévy framework, in which both parties are ambiguous about the intensity and severity of insurable losses. Both the buyer and seller aim to maximize their expected wealth,...

Spatial Oligopolies with Cooperative Distribution
Sandsmark, Maria - 2009
The main objects here are Nash equilibria in spatial Cournot oligopolies when profits depend on coordinated distribution. Production is non-cooperative, but the subsequent transportation must be performed jointly to minimize costs. Cournot-Nash equilibria for this two-stage game with partial...

While linear programming establishes insight in optimal farm plans for farmers that … cooperate, game theory is used to generate fair divisions of the extra gain that is established by cooperation.The model is … the individual gross margins. To divide these gains, we consider four established solution concepts from game theory that …

Equilibrium Points of Bimatrix Games Using Bilinear and Linear Programming
Lahiri, Somdeb - 2021
In this note we show without using any fixed-point theorem argument, that a pair of vectors is an equilibrium point of a bimatrix game if it solves a certain bilinear programming problem. Since the bilinear programming problem we consider has an optimal solution, we are able to prove the...
