Abstract

En el presente documento se estudia si durante el período comprendido entre enero de 2008 y mayo de 2017 se produjo en Uruguay un proceso de convergencia de precios a nivel de establecimientos de venta. Se utiliza un panel de datos conformado por precios diarios de 4 bienes fijados por 386 supermercados, con cobertura nacional. Los bienes fueron seleccionados buscando representar categorías de productos para las cuales los hogares suelen realizar compras en un supermercado con alta frecuencia. El análisis de convergencia se realiza a partir del estudio de la evolución de la dispersión de precios en el tiempo. Se encuentra que esta se redujo en el período solamente 0,88 % a nivel de todo el país, por lo que no parece suficiente como para concluir que los precios hayan convergido. Este resultado era esperable debido a que las posibles fuentes de diferenciales de precios no registraron cambios significativos durante el período. Por lo tanto, la reducción en la dispersión de precios estimada no parece suficiente como para afirmar que la Ley de un Solo Precio en su versión absoluta se cumple en el largo plazo en el país. Como parte del análisis de robustez, se realizan estimaciones para diversas desagregaciones territoriales, así como para diferentes momentos de ingreso de los establecimientos a la muestra y para distintos niveles inflacionarios. El resultado encontrado es robusto para diferentes desagregaciones territoriales.
