Resumen

This paper discusses whether Law 28300 of 2004, that required Peruvian firms to express their prices in Peru's currency in a context of high price dollarization, affected the exchange rate pass-through (ERPT). We hypothesize that the enactment of the Law introduced menu costs for firms that used to set their prices in dollars, prompting several of them to make a permanent switch to pricing in local currency. Using disaggregated consumer price index (CPI) data, we find that, following passage of the Law, the ERPT was completely offset for non-durable goods with dollarized prices, and partially offset for durable goods with dollarized prices. These effects may vary due to differences in imported component shares, market power, and markup pricing.
