Abstract

Resumen Este trabajo desarrolla en forma pormenorizada la metodología de datos panel para encontrar la mejor especificación econométrica de una función de producción, al comparar la Cobb-Douglas y la translogarítmica con datos del sector financiero colombiano. Se encuentra que la función que mejor se ajusta es la translogarítmica con efectos fijos, lo que indica que, por un lado, existen diferencias significativas en los retornos del capital y del trabajo sobre los ingresos entre bancos y, por otro lado, que existen efectos de segundo orden en el sector y que las elasticidades son variables. Además, se encuentra que el capital y el trabajo tienen productividades marginales decrecientes y estos dos factores son complementarios. Por otro lado, se demuestra que la elasticidad del capital es unitaria y significativa, mientras que el factor trabajo solo complementa al capital, siendo más una herramienta que un aporte significativo para el ingreso de los bancos.
