The unavailability of geographically disaggregated information does not allow obtaining empirical evidence in order to answer some important questions in the field of urban and regional economics. The objective of this work is to calculate the Gross Domestic Product (GDP) at local level, for the 42 municipalities of Valle del Cauca – Colombia in 2010, using ecological inference techniques based on entropy models that have already been applied in Spain and Mexico with satisfactory results.
The proposed method and the application of ecological inference allows of the GDP disaggregated by the 11 economic sectors, a pioneering and very useful work in the region.
