This paper explores how European Monetary Union will change the wage settin
g behavior of national labor unions. We derive the impact of national infla
tion aversion and labor militancy on the performance of national labor mark
ets under different monetary arrangements. A common central bank raises inf
lation and unemployment if it acts as conservatively as national central ba
nks. However, unemployment falls in countries that previously tied their mo
netary policy to the Bundesbank. We also examine the composition of EMU and
the influence of national labor market legislation.
