Medición de cambios en productividad con indicador de Luenberger en el sector de seguros en Argentina a la salida de la crisis
AbstractA severe macroeconomic crisis resets economic sectors. This is so when the GDP growth rates move between great falls and important recoveries, and when relative prices vary importantly. The insurance sector in Argentina offers an interesting laboratory to explore with Luenberger Productivity Analysis what happened to a sector very sensitive to the macroeconomic performance, inflation and currency depreciation. The methodology was chosen because it confers flexibility, since presupposes profit maximization, on one hand, but do not constrain the orientation of the model (i.e., input-oriented, output-oriented), allowing to study productivity changes due to both, input and output adjustments. Moreover, we use output and input monetary measures (in constant values), aiming to increase the flexibility in the adjustment to higher profits. The results show according to different models a sector with scarce productivity growth or stagnated, with important variability between better and worse results. The indicator in use permits to split changes in efficiency and in technical change.
