Resumen
El presente trabajo busca contribuir teórica y empíricamente con un modelo de
desatención racional con tipo de cambio para una economía pequeña y abierta
como la peruana. Para ello se plantea que debido a que los agentes, en este
caso las empresas, tienen una capacidad limitada de procesamiento de
información y, por ende, de prestar atención, entonces deben elegir a qué
variables prestar una mayor cantidad de atención. En ese sentido, este trabajo
modela el problema del nivel de atención que tiene la firma con respecto a las
variables que impactan en el precio óptimo, es decir el que maximiza su
beneficio. Por tanto, ante una mayor volatilidad en las variables que afectan a los
costos de las firmas, como el tipo de cambio, las empresas prestan mayor
atención a dichas variables, de modo que los precios se ajustan rápidamente y,
a consecuencia de ello, se genera un efecto traspaso. Sin embargo, la
intervención cambiaria de la autoridad monetaria puede reducir el ruido de las
señales del tipo de cambio que observa la empresa, y generar que se preste
menos atención, lo que conlleva a que se reduzca el efecto traspaso. Para ello,
se realizó dos modelos: benchmark y desatención racional como fuente de
rigidez de precios, para este último se siguió a Sims (2003), Wiederholt (2010) y
Maćkowiak & Wiederholt (2009).
This paper contributes theoretically and empirically with a rational inattention model with exchange rate for a small and open economy like the Peruvian one. In this case, firms have a limited capacity to process information and, therefore, to pay attention, so they must choose which variables to pay attention to. In this sense, this paper models the problem of the level of attention that the firm has with respect to the variables that impact the optimal price, that is, the one that maximizes its profit. Thus, in the face of greater volatility in the variables that affect firms’ costs, such as the exchange rate, firms pay more attention to these variables, so that prices adjust rapidly and, as a consequence, a pass-through effect is generated. However, exchange rate intervention by the monetary authority can reduce the noise of exchange rate signals observed by the firm, and cause less attention to be paid, leading to a reduction of the pass-through effect. Two models were conducted for this purpose: the benchmark and the rational inattention as a source of price rigidity, for the latter it was followed Sims (2003), Wiederholt (2010) and Maćkowiak & Wiederholt (2009).
