Marginal employment', i.e. employment at low working hours and earnings not covered by social security, has been gaining importance in the German economy over the past decade. Using a large newly available panel data set and statistical matching techniques, we analyse the effects of marginal...

We provide a methodology to study the role of market distortions on the emergence of indeterminacy and bifurcations. Most of the specific market imperfections considered in the related literature are particular cases of our framework. Comparing them we obtain several equivalence results in terms...

Having faced high unemployment rates for more than a decade, the German government implemented a comprehensive set of labour market reforms during the period 2003-2005. This paper describes the economic and institutional context of the German labour market before and after these so-called Hartz...

The Great Recession triggered a resurgence of short-time work (STW) throughout the OECD. Several countries introduced from scratch STW or significantly expanded the scope of the programmes already in place. In some countries like Italy, Japan and Germany between 2.5 and 5 per cent of the...
