The building blocks of social trust. The role of customary mechanisms and of property relations in the emergence of social trust in the context of the commons.

This paper argues that social trust is the emergent product of a complex system of property relations, backed up by a sub-system of mutual monitoring. This happens in a context similar to Ostrom’s commons, where cooperation is necessary for the management of resources, in the absence of external authorities to enforce sanctions. I show that social trust emerges in this context because of an institutional structure that enables individuals to develop a generalized disposition to internalize the external effects of their actions. This is made possible by the “patrimonial” nature of this structure.
