This article develops a model that treats to explain the coevolution between the social governance and the economic modernization. On the basic of a traditional economy-relational transactions and, groups with a high grade of social cohesion a modern economy is reached-transactions in anonymous markets and an insignificant grade of social cohesion. In the transition, the decrease in the social cohesion may cause that this cooperation collapses if the economy crosses a threshold of complexity (distance trade) before sanctions to third parties emerges. In this sense it is said that institutions are crucial for market development and generalization of cooperation. The model uses an endogenous network, in which the agents interact through a space evolution game.
