A new model of TU game is introduced and studied. Here apart from the characteristic function, two additional functions are used: relations between the players and the probability of coalition formation. We suggest and study the sufficient properties of the probability function to transform it...

Differential information economies are investigated from the viewpoint of contract based approach, developed in series of author's papers. The key idea of the approach is to change the study of a “final” allocation of commodities with (different forms) stable webs of barter contracts which...

The paper applies and elaborates contractual approach to study economies with a production sector. Economies with convex, non-convex production and with public goods are considered. The notions and terms of barter contractual approach developed in Marakulin (2003a) for exchange economies are now...

The paper presents and studies a new concept of coalition domination for incomplete markets. It was elaborated applying a contractual approach and based on the notion of fuzzy contractual allocation, see Marakulin (2011, 2013). Core allocations are implemented by the net trades (webs of...

The goal of the paper is to propose and study a concept of contract-based domination by coalitions for competitive economies. The formal mathematical notion of contract (an elementary exchange of commodities), the contractual allocations of different kinds and their stability properties are...

The study is aimed to investigate the convergence to equilibrium of trajectories generated by contractual processes. “Contractual process” is a view on economy’s self-regulation, describing any state of exchange economy as a set of barter contracts among agents/coalitions. It is assumed...

A domination concept, based on the notion of an exchange contract, is proposed and studied in this paper. Doing so, the classical notion of domination via coalitions is transmitted onto systems (webs) of contracts and onto allocations, whose stability is investigated. This way, the proposed...
