CPI Inflation Targeting and Exchange Rate Pass-through

Abstract

This paper analyzes how imperfect exchange rate pass-through affects the transmission of the CPI inflation targeting optimal monetary policy. In the short run, delayed pass-through constraints monetary policy more than incomplete pass-through and interest rate smoothing amplifies this effect. In addition, imperfect pass-through does not increase the variability of the real exchange rate for a subset of strict CPI inflation targeting cases and for flexible CPI inflation targeting. Furthermore, there exists an inverse relation between the pass-through and the insulation of CPI inflation from foreign shocks, and when the pass-through falls, the impact on the trade-off between the stabilization of both CPI inflation and output depends on how strictly the central bank is targeting CPI inflation and on the kind of imperfect pass-through.Inflation Targeting; Exchange Rate Pass-through; Open-economy; Direct Exchange Rate Channel; Optimal Monetary Policy.
