Análisis de la eficiencia bancaria en Ecuador, el Salvador y Panamá para el periodo 2007-2021.

Abstract

This research contributes to the literature and the monitoring of banks in the absence of studies focused on bank efficiency in the three dollarized countries. A two-stage analysis is proposed, in which a non-parametric methodology called Data Envelopment Analysis (DEA) is applied to a sample of 138 banks to calculate a comparative measure of bank efficiency. In the second stage, the determinants of bank efficiency are analyzed by means of a data panel regression model with a set of financial, economic, and regulatory data as explanatory variables. The results suggest that size, solvency, liquidity, profitability, market concentration, GDP and the regulatory environment are determinants of bank efficiency for the three dollarized countries.
