I study the effects of entry to the European Monetary Union (EMU) on relative purchasing power parity (PPP) convergence using monthly disaggregated price indices from 32 European countries from 1999 to 2016. I examine the entry of Cyprus, Malta, Slovakia, and Slovenia to the EMU, and I estimate the bands of inaction of relative prices before and after entry using a threshold autoregressive model. I find a positive effect of the EMU on relative PPP convergence: after entry, the bands of inaction with EMU members fell by 17 percent. Cross‐sectional evidence supports the theoretical prediction that bands of inaction are related to transaction costs.
