The model take into account time spent on transations ("trade distance"). It is shown that the same set of traders may generate trade networks of different structures depending on average trade distance. When the latter is small, the market is neaar competitive. When the trade distance is large, the set of traders exhibits monopolistic behavior. The model is studied both analytically and via computer simulations.  Ключевые слова mathematical model, self-organisation, trade networks, transition economy   Полный текст     в формате pdf
