Abstract

En este artículo se aplican algunas técnicas y procedimientos econométricos para el análisis de la convergencia económica regional en precios, con el fin de evaluar la Ley del Único Precio en Colombia, a través del índice de precios al consumidor (IPC) para las trece principales ciudades del país. Específicamente,se emplean pruebas para el análisis de integrabilidad y cointegración para series de tiempo, tanto para los niveles de índices, como para las variaciones anuales. A través de estos procedimientos se puede evaluar el comportamiento de cada uno de los precios regionales con los precios nacionales, mostrando la elasticidad de largo plazo entre los precios y su nivel medio de diferencia. Los resultados muestran que, en promedio, los precios de Bogotá, Cali, Manizales y Pasto han estado situados por encima del nivel nacional y, de igual manera, su variación ha estado por debajo de la variación de precios a nivel nacional, durante el periodo estudiado.******In this paper we apply some techniques and econometric methods to the analysis of regional economic convergence in prices to assess the law of one price in Colombia, through the Consumer Price Index (CPI) for the 13 largest cities. Specifically used for tests and cointegration analysis integrability for time series for both index levels, and for annual variations. Through these procedures may evaluate the performance of each of the regional prices with domestic prices, showing the long-term elasticity between prices and their average level of difference. The results show that on average, prices of Bogota, Cali, Manizales and Pasto have been placed above the national level and, just as its variation has been below the national price change during the study period.
