The use of large datasets for macroeconomic forecasting has received a great deal of interest recently. Boosting is one possible method of using high-dimensional data for this purpose. It is a stage-wise additive modelling procedure, which, in a linear specification, becomes a variable selection...

Insufficient capital buffers of banks have been identified as one main cause for the large systemic effects of the recent financial crisis. Although higher capital is no panacea, it yet features prominently in proposals for regulatory reform. But how do increased capital requirements affect...

We study the mechanisms that are associated with the gender education gap and its reversal in Germany.
