This paper examines the presence of nonlinear mechanism in the exchange rate pass-through (ERPT) to CPI inflation for 12 euro area (EA) countries. Using logistic smooth transition models, we explore the existence of nonlinearity with respect to economic activity along the business cycle. Our results provide a strong evidence of nonlinearity in 6 out of 12 EA countries with significant differences in the degree of ERPT between the periods of expansion and recession. However, we find no clear direction in this regime-dependence of pass-through to business cycle. In some countries, ERPT is higher during expansions than in recessions; however, in other countries, this result is reversed. These cross-country differences in the nonlinear mechanism of pass-through would have important implications for the design of monetary policy and the control of inflation in the EA context.
