A partly heuristic attempt is made to explore long-run policies aimed at a
second-best compromise between ex ante risk-sharing efficiency and ex post
productive efficiency. Wage subsidies for low-skilled workers financed by t
axes on high wages are advocated, together with improved risk sharing betwe
en capital and labour, between generations and among the countries belongin
g to EMU. The scope of the policies advocated is limited by considerations
of moral hazard, time consistency and fiscal competition. Moreover, estimat
es of some key economic parameters remain very imprecise. Several avenues o
f further research are identified.
