Matrices Insumo-Producto y Análisis de Multiplicadores : Una Aplicación a Colombia (Input-Output Matrices and Multiplier Analysis: An Application for Colombia)

Input-output analysis is widely used in different scenarios, because it is easy to implement and interpret. Nevertheless, it is important to note that input-output coefficients should be built with caution, especially in the case of secondary production, as this may imply negative coefficients. To overcome this problem the coefficients were constructed indirectly, applying this methodology using data from the 2007 national accounts, base 2000. Using these new coefficients, we performed a traditional multiplier analysis to obtain the key sectors of the economy. This analysis is sensitive to the level of disaggregation used
