Función de producción Cobb-Douglas : evidencia estadística y econométrica en el sector bancario privado ecuatoriano, periodo 2015 - 2020.

Abstract

The study analyzes the impact of labor and capital factors on the total banking product, within the framework of the development of the Cobb-Douglas production function through statistical and econometric evidence in the Ecuadorian private banking sector in the period 2015-2020. Ecuadorian banking system experienced low liquidity and costly access to financial markets; For this reason, multilateral credits were granted to favor the national bank, which made this injection carried out accumulate liquidity in the banking system and there is a slowdown in negotiated credits; For this reason, the Ecuadorian economy triggered a broad deflationary process, caused mainly by the fragility of domestic demand, unproductiveness and financial inefficiency, such that the Ecuadorian banking system in 2020 presented a decrease of 2.7%. To evaluate the situation through mathematical programming, a database for the 24 Ecuadorian private banks with time series was used to carry out an econometric modeling with the Ordinary Least Squares method, including the autoregressive distributed lag (ARDL), which evidenced the growing economy of scale in the sector with 1.36; and, the joint unproductiveness of the factors of production, to the total bank income evidenced by the concentration of 63.65% of banks in an oligopolistic market clearly positioned in Ecuador. The labor factor has a greater participation in the total Ecuadorian banking product, and has a positive elasticity; For its part, the capital factor shows inelasticity, that is, a variation of this factor does not affect Ecuadorian banking production.
