VILLAMIL S, Julián  e  HERNANDEZ, Gustavo. Chains, clusters and workflows in the Colombian economy. Ens. polit. econ. [online]. 2016, vol.34, n.spe79, pp.51-65. ISSN 0120-4483.  https://doi.org/10.1016/j.espe.2016.01.003.

To design economic policy, it is very important to know in depth the interdependence of the economic structure. This work uses the input-output (I/O) model for economic analysis. Two approaches, not traditionally used, are applied to analyse the Colombian economy: spectrum of different I/O coefficient matrices (Dietzenbacher, 1992) and clustering techniques (Garbellini y Wirkierman, 2014). As a result, indicators of linkages are obtained without bias of overestimation or underestimation. Additionally, clusters are identified endogenously. Furthermore, embodied labour flows that spread through the network-production are calculated. Each of these flows is broken down into indicators that characterise the clusters according to their proximity to final demand, to their degree of cohesion to the network, and to their importance for the rest of the system.
