This paper deals with the development of a mathematical theory for complex socio-economical systems. The approach is based on the methods of the mathematical kinetic theory for active particles, which describes the evolution of large systems of interacting entities which are carriers of specific functions, in our case economical activities. The method is(More)
A laboratory experiment was performed as replication of the original one created by M. Cohen and P. Bacdayan at Michigan University. It consists in a twopersons card game played by a large number of pairs, whose actions are stored in a computer's memory. In order to achieve the final goal each player must discover his sub-goals, and must coordinate his(More)
This paper builds upon a view of economic organizations as problemsolving arrangements and presents a simple model of adaptive problemsolving driven by trial-and-error learning and collective selection. Institutional structures, and in particular their degree of decentralization, determines which solutions are tried out and undergo selection. It is shown(More)
This paper addresses the problem of division of labour as an evolutionary process in which co-ordinated agents attempt problem-solving as a search in problem space. Co-ordination stress and learning trigger adaptation but as complexity rises radical solutions are sought prompting radical organisational as well as technological change. The analytical issues(More)
The paper develops a theory of biases in decision making. Discovering a strategy for solving a game is a complex problem that may be solved by decomposition; a player decomposing a problem into many simple subproblems may easily identify the optimal solution to each sub-problem: however it is shown that even though all partial solutions are optimal, the(More)
Acknowledgements The research for this paper was supported by the DYNACOM project financed through the TSER Programme of the DG12 of the European Commission (Contract No. SOE1-CT1078). I am especially indebted to Clive Lawson who first suggested that I write a paper addressing the relevance of J.R. Commons' institutional economics to contemporary debates on(More)
The treatment of knowledge and uncertainty is one of the main issues in the theoretical and methodological distinction among different schools of thought and approaches in economics. This paper surveys the economic literature to associate several economists and schools of economic thought with a particular concept or combination of concepts of uncertainty.(More)
