Abstract

In this paper, we calculated the potential output for the Costa Rican economy. First, we applied several different methods to calculate this non-observable variable, such as the Beveridge-Nelson decomposition, Hodrick-Prescott filter, production function, Kalman filter, and SVAR. Then, we combined the results of these methods using Bayesian Model Averaging (BMA) and a Phillips curve. Finally, we obtained optimal weights for each estimated potential product and estimated an indicator of the potential output series. ***Resumen: En el documento se realizan distintas metodologías de estimación del producto potencial para la economía costarricense. Dentro de los métodos que se utilizan para estimar esta variable no observable, se pueden mencionar la descomposición Beveridge-Nelson, el filtro Hodrick Prescott, la función de producción, el filtro de Kalman y el VAR estructural (SVAR). Los resultados de estos modelos se promedian empleando el método de Ponderación bayesiana de modelos (Bayesian Model Averaging, BMA), por medio de una curva de Phillips, con el fin de determinar los pesos óptimos para la obtención de un único indicador de producto potencial.
