Public sector unions push for unmerited wage increases, exacerbating inflation and deficits. Despite this conventional wisdom, governments in several European countries successfully limited public sector wage growth during the 1980s and 1990s. It is argued in this paper that the recent rise in public sector wage inflation in the Euro-zone...
