Structural equivalence in the input-output field

Resumen

The systematic study of the way in which intersectoral transactions are organized is an interesting source of information about the pattern of existing economic relationships in one country that allows comparison of its structural features with those of another economy of reference. A new tool in the input-output context that allows us to reveal the functioning economic structure by determining the structural equivalent sectoral groups is proposed. The concept is close to the Network and Graph theories. Its implementation is very flexible and can be applied both Boolean or valued graphs overcoming the usual criticisms of qualitative inputoutput studies.
