The methods of social network analysis have been subjects of great interest and extensive development in recent years. Wider use and further development of these methods could lead to work on economic organization and economic process that is, more strictly, formally comparable from case to case and from study to study. This paper details some of the fundamental, matrix-based procedures used in network analysis and interprets them in terms of culture theory and social structure. An example is developed in which the economic structure of a farming village is analyzed using block-modelling techniques and in which prin­ciples of economic culture in the village are inferred from the modelling results.
