On the basis of a theoretical model, we argue that higher aggregate unemployment affects individual returns to education. We therefore include aggregate unemployment and an interaction term between unemployment and the individual education level in a standard Mincer equation. Our results show...

Subsidising research networks has become a popular instrument in technology policies, driven mainly by expected positive spillovers. In particular, the stimulation of R&D co-operation between scientific institutions and industry is considered as most promising. In the context of policy...

In this paper data from a survey of 1,771 inmates conducted in 31 German prisons provide microeconometric evidence on the relationship between individual anticipated labour market opportunities and the perceived probability of future recidivism. Results show that inmates with poor labour market...
