In this sample article from the September 2005 edition of Economic Affairs, W. S. Siebert shows how labour market regulation that undermines freedom of contract leads to fewer, higher productivity jobs with employment being across a narrower range of ages. More people are excluded from the labour market in highly regulated countries and they remain unemployed for longer.
