This paper deals with designing emissions trading in practice. After a short introduction to the general idea of emissions trading, practical requirements for the introduction of an emissions trading scheme are considered, including the temporal and spatial dimension as well as administrative...

The need to balance austerity with growth policies has put government efficiency high on the economic policy agenda in Europe. Administrative reforms which boost the efficiency of the administration can alleviate the trade-off between consolidation and public service provision. Against such...

Hydrogen is often seen as a promising future energy carrier given the major reliance of today's transport sector on finite fossil fuels. This working paper assesses the macroeconomic effects of introducing hydrogen as fuel in passenger transport within the framework of the computable general...

This paper provides firm-level evidence for the relationship between the age structure of the workforce and the adoption of new or significantly improved technologies in service sector firms. Furthermore, it closes a research gap by analyzing the joint impact of the age of the workforce and the...

This paper examines return predictability when the investor is uncertain about the right state variables. A novel feature of the model averaging approach used in this paper is to account for finite-sample bias of the coefficients in the predictive regressions. Drawing on an extensive...
