Abstract

Motivado por el desarrollo del comercio electrónico y la importancia de la rigidez de precios para explicar los efectos reales de choques monetarios, el presente trabajo de investigación tiene como objetivo evaluar el grado de rigidez de los precios en línea en el Perú. Para ello, se analizan 4.5 millones de precios publicados diariamente en la página web de una tienda por departamentos que, durante el periodo de análisis, tuvo una participación de mercado de aproximadamente 50 por ciento. Esta gran cantidad de datos o “big data” fueron obtenidos a través de la técnica de raspado de datos de la web o “web scraping”, la cual fue aplicada diariamente entre los años 2016 y 2020. Tomando en cuenta la frecuencia de cambio de precios y la duración de los mismos, los resultados indican que los precios en línea en el Perú son menos rígidos que en otros países.
