A survey of the results relating to the application of gross substitutability in economic equilibrium theory. The topics considered include existence and uniqueness of equilibrium, comparative statics, coalition stability, and stability of price-adjustment tatonnement processes. The main...

In this paper, a new concept of "limit information" is introduced and studied for Arrow-Debreu type economies with asymmetrically informed agents. The concept is based on the so-called contractual approach that presumes that agents meet and form coalitions, where the concurrent exchange of...

A new concept of contract-based domination by coalitions for competitive economies is proposed and studied in the paper. This concept is based on the notion of (barter) contract (an elementary exchange of commodities). Here classical coalitions domination is transferred onto systems (webs) of...

We develop a turnpike theory for a class of dynamic general equilibrium models where total demand function satisfy monotonicity conditions. As special cases, we receive well known results about asymptotic behavior of optimal paths.

A brief survey of the publications in mathematical economics, dealing with utility theory, probabilistic microeconomic models, and equilibrium under price rigidities, is given.

Consider an economy with n resources (goods) and m agents, and let initial resource allocation be given. We ask if it is possible to build a mutually beneficial bargaining sequence that approaches an optimal resource allocation even though a) only k ≤ n agents participates at each step of the...

The monography considers laws and mechanisms of social development from positions of positivism, dialectic materialism and the theory of systems. The methodology of the author is based on causality in relations of a society and social institutes. Social development is considered as result of...
