Trust and cooperation in buyer–seller relationships and networks. The co-evolution of structural balance and trust in iterated PD games

Our study has two aims: to elaborate theoretical frameworks and introduce social mechanisms of spontaneous co-operation in repeated buyer-seller relationships and to formulate hypotheses which can be empirically tested. The basis of our chain of ideas is the simple two-person Prisoner’s Dilemma game. On the one hand, its repeated variation can be applicable for the distinction of the analytical types of trust (iteration trust, strategy trust) in co-operations. On the other hand, it provides a chance to reveal those dyadic sympathy-antipathy relations, which make us understand the evolution of trust. Then we introduce the analysis of the more complicated (more than two-person) buyer-seller relationship. Firstly, we outline the possible role of the structural balancing mechanisms in forming trust in three-person buyer-seller relationships. Secondly, we put forward hypotheses to explain complex buyer-seller networks. In our research project we try to theoretically combine some of the simple concepts of game theory with certain ideas of the social-structural balance theory. Finally, it is followed by a short summary.

International cooperation against climate change: institutions, policies and their efficiency

In the 20th century nature of the world economy has started to change significantly, and the former state-centric constellation disappeared. Several development factors that induced the change are still active and nowadays we live in a much different world. The world economy consists of transnational networks; these complicated systems have a great impact on the world of states. The transnational actors’ (multinational corporations, non-governmental organizations etc) influence became very essential as they are able to mobilize the society, have high expertise (think tanks), but it is also important to note their financial strength and moral effects (norm entrepreneurs).
