Abstract

In a country that adopted inflation targeting like Costa Rica, estimating the pass-through of the policy rate to banking retail rates is fundamental. We take into account imperfect competition, degree of dollarization, asymmetric regulation and whether banks are state or private to delimit the monetary policy rate (TPM) effectiveness. We generalize a Cournot-type competition model to allow for adjustment costs and use loan and deposit micro-data to estimate the magnitude and speed of the pass-through. We find important pass-through asymmetries due to market power, regulatory asymmetries, and degree of dollarization, all of which lower pass-through. Our evidence shows that the pass-through has increased relative to previous studies. ***Resumen: En un país con metas de inflación como Costa Rica, la estimación del traspaso de la tasa de política monetaria a las tasas ofrecidas por los bancos comerciales es fundamental. Tomar en cuenta la competencia imperfecta, la dolarización, la asimetría regulatoria y los tipos de bancos estatales y privados permite delimitar la efectividad de la Tasa de Política Monetaria (TPM). Con una generalización de un modelo de competencia tipo Cournot, con coste de ajuste y datos a nivel micro de préstamos y depósitos, se estima la magnitud y velocidad de traspaso. En general, existen importantes asimetrías en el traspaso debido al poder de mercado, asimetrías regulatorias y dolarización, todo lo cual merma la efectividad de la TPM. Mayor competencia, disminución de la dolarización, los costos de ajuste y de las asimetrías regulatorias mejoraría la fuerza y velocidad del traspaso. Por último, la evidencia muestra un traspaso más rápido respecto a estudios previos.
