ABSTRACT
Research reported in this chapter was partly carried on within the Industrial Dynamics and European Employment (IDEE) project, with M.Amendola, B. Böhm and C.Longhi as other principal researchers. Though with the usual caveats, we thank them for letting us draw also from their contribution to such joint effort. Moreover, Punzo gratefully acknowledges the financial support of a UNISI PAR project, 2002–2004.
