Part of the Lecture Notes in Economics and Mathematical Systems book series (LNE, volume 551)


This paper analyzes the structural relationships of the financial transactions represented in a Social Accounting Matrix (SAM) for the Mexican economy through a pretopological approach. Based on a simple binary relationship between incomes and expenditures of institutional accounts, the pretopology is used as a mathematical tool to get an insight into the economic structure represented by the SAM. Such an analysis can be useful to identify the set of relationships between several institutional accounts, ordered according to their influence or domination.
