Convex analysis and financial equilibrium

Convexity has long had an important role in economic theory, but some recent developments have featured it all the more in problems of equilibrium. Here the tools of convex analysis are applied to a basic model of incomplete financial markets in which assets are traded and money can be lent or borrowed between the present and future. The existence of an equilibrium is established with techniques that include bounds derived from the duals to problems of utility maximization. Composite variational inequalities furnish the modeling platform. Models with and without short-selling are handled, moreover in the absence of any requirement that agents must initially have a positive amount of every asset, as is typical in equilibrium work in economics.     

Program Absorption Operators in the Theory of Nonzero-Sum Differential Games

This paper is devoted the Nash equilibrium payoffs for differential games. The Nash equilibrium is one of the key concepts in the theory of noncooperative nonzero–sum two-person games. The Nash equilibrium is broadly applicable in economics as well as in biology and in, particularly, in ecology.

A note on the strategic adoption of a new technology

This note reports an application of two-person, nonzero-sum game theory to a problem in the economics of technology adoption. It extends the analysis of a previous paper to consider differentiable mixed-strategy equilibria. In this case, the mixed-strategy equilibrium has a natural interpretation as a pure strategy equilibrium in an appropriately defined differential game.

Stationary points and equilibria

Almost all existence results in mathematical economics and game theory rely on some type of fixed point theorem. However, in many cases it is much easier to apply an equivalent stationary point theorem. In this survey paper we show for various general equilibrium and game-theoretical models the usefulness of the stationary point approach to prove existence of equilibrium. We also consider path following methods to find a stationary point and illustrate such methods by an example. Finally, we discuss some refinements of stationary points and their application to solve the problem of equilibrium selection.     

Equilibrium programming:The path following approach and dynamics

A general formulation of equilibrium is introduced which subsumes a large range of equilibrium models in economics, mathematical programming, game theory, networks, organizations, etc. The existence of a solution is proved by path following and without invocation of a fixed point theorem. The path following procedure provides new means for establishing existence of equilibria, for constructing them and for interpreting them. A dynamic equilibrium model is also presented and the existence, stability and computation of dynamic equilibrium paths are discussed. Moreover, these paths can often be interpreted as adjustment processes.     

消费者连续统集合下一种投入产出经济的均衡和一般均衡价格

本给出了一个经济模型把跨期间的一般均衡理论和neo-Ricardian的生产价格理论联系起来，并改进了Roce-Anne Oana模型[1][2]。即把消费有限改变消费连续统，并在Rose-Anne Dana模型的基础上，加了条件C.4和C.7，得出了两个重要的结果：（1）在标准条件下，此模型有一均衡使得每一个生产的每期最大利润是相等的；（2）如考虑生产价格是稳定价格；且等于最大利润；则在适当的条件下，这样的价格系统是存在且唯一的，而所定义的均衡的非折扣的价格序列收敛于生产价格。因此均衡价格依赖于技术和消费特征，但在取极限时，有关价格仅依赖于技术。

LOCATIONAL EQUILIBRIUM MODELS FOR PUBLICLY OWNED RESIDENTIAL LAND

ABSTRACT. Perturbation and matched asymptotic expansion methods are shown to be useful to the study of land economics. In the context of residential land management theory, the present study complements a previous analysis of locational equilibrium economic models for residential land in Wan [1977] and extends it beyond absentee ownership to include public ownership and mixed ownership. The dependence of the optimal uniform household utility on the (radial) distribution of land fraction for housing space is delineated.

Some recent results inn-person game theory

The discussion will center mainly on some work on two solution concepts: the core for gaines without side payments and the nucleolus for games with side payments (characteristic funtion games). The core has become an important equilibrium concept in mathematical economics. The nucleolus is related to the theory of bargaining sets.This paper was presented at the 7th Mathematical Programming Symposium 1970, The Hague, The Netherlands.This work was supported by the National Science Foundation under grant GK-4795.     

John von Neumann, the Mathematician

Imagine a poll to choose the best-known mathematician of the twentieth century. No doubt the winner would be John von Neumann. Reasons are seen, for instance, in the title of the excellent biography [M] by Macrae: John von Neumann. The Scientific Genius who Pioneered the Modern Computer, Game Theory, Nuclear Deterrence, and Much More. Indeed, he was a fundamental figure not only in designing modern computers but also in defining their place in society and envisioning their potential. His minimax theorem, the first theorem of game theory, and later his equilibrium model of economy, essentially inaugurated the new science of mathematical economics. He played an important role in the development of the atomic bomb. However, behind all these, he was a brilliant mathematician. My goal here is to concentrate on his development and achievements as a mathematician and the evolution of his mathematical interests.     

Hölder Continuity of Solutions to Parametric Vector Equilibrium Problems with Nonlinear Scalarization

In this article, using the nonlinear scalarization approach by virtue of the nonlinear scalarization function, commonly known as the Gerstewitz function in the theory of vector optimization, Hölder continuity of solution mappings for both set-valued and single-valued cases to parametric vector equilibrium problems is studied. The nonlinear scalarization function is a powerful tool that plays a key role in the proofs, and its main properties (such as sublinearity, continuity, convexity) are fully employed. Especially, its locally and globally Lipschitz properties are provided and the Lipschitz property is first exploited to investigate the Hölder continuity of solutions.     

The dynamics of Bertrand model with bounded rationality

The paper considers a Bertrand model with bounded rational. A duopoly game is modelled by two nonlinear difference equations. By using the theory of bifurcations of dynamical systems, the existence and stability for the equilibria of this system are obtained. Numerical simulations used to show bifurcations diagrams, phase portraits for various parameters and sensitive dependence on initial conditions. We observe that an increase of the speed of adjustment of bounded rational player may change the stability of Nash equilibrium point and cause bifurcation and chaos to occur. The analysis and results in this paper are interesting in mathematics and economics.     

Dynamical principle

We suggest a formulation of the dynamical principle for mechanics in which time is not a preferred evolution parameter but plays the role of a new generalized coordinate. The advantage of this approach is the possibility of extending it to dynamical systems in which there is no natural evolution parameter (thermodynamics, equilibrium economics, and the like). __________ Translated from Teoreticheskaya i Matematicheskaya Fizika, Vol. 153, No. 1, pp. 18–28, October, 2007.
