Abstract: Membership in a monetary union (EMU) is likely to imply stronger incentives for nominal wage flexibility in the form of wage indexation and shorter contract length than non-membership. For example, EMU entry may cause a move from a nonindexation to an indexation equilibrium. But more wage flexibility is only an imperfect substitute for an own monetary policy. It is possible that an increase in wage flexibility is welfare-decreasing, because of the accompanying rise in price variability. If indexation occurs outside the EMU, either multiple equilibria or full-indexation equilibria may occur.
