Abstract: The input output analysis is used by a lot of cities with the objective to study interregional trade problems. We focused our work on Argentina, and we present a model with two regions: Buenos Aires city and the rest of the country. Buenos Aires does not have an Input Output Tables or a regional account system, so we have to estimate the model with non-survey and calibration techniques. Non-survey techniques are commonly used to model intraregional trade in a region. We used the AFLQ location quotient to estimate the trade in each region. Then we must to compute the regional imports/exports, and for this we based our work on calibration techniques. Biproportional adjustment (RAS) and cross entropy were the calibration techniques used to build the interregional input output model. In the presented case the work find that cross entropy could reply exactly the national input output tables, because it enforce additional constraints. If we look the results, RAS technique overestimate the Buenos Aires technical coefficients compared with cross entropy. There are not substantial differences on technical coefficients between RAS and cross entropy in the other region.
