“…To consider this issue, a framework is developed which allows analysis of the strategic indexation choices of a finite number of unions, each representing a non-negligible fraction of the economy's total labor force, but which also encompasses both the possibility of a single economy-wide union and that of a continuum of atomistic unions as limiting cases. A substantial body of work concerned with the macroeconomic implications of strategic behavior by non-atomistic unions now exists: see, for example, Skott (1997), Cukierman and Lippi (1999), Lawler (2000Lawler ( , 2001, Soskice and Iversen (2000), Lippi (2003), Holden (2005), and Coricelli, Cukierman, and Dalmazzo, (2006). The focus of this literature has, however, been almost exclusively on the consequences of the interaction between union wage setting and the conduct of monetary policy for optimal policy design.…”
