Labour market reforms that are designed to stimulate labour supply at the lower end of the wage distribution can never be precisely restricted to affect only the target group. Spillovers to and feedback from other segments of the labour market are unavoidable and may counteract the direct...

Die sogenannten HartzReformen beinhalten eine Umstrukturierung und Reorganisation der Tätigkeit der Bundesagentur für Arbeit und eine Reform von Instrumenten der Arbeitsmarktpolitik. Trotz der seinerzeitigen Skepsis führender Ökonomen stellen diese Reformen einen bedeutenden Fortschritt in...

The question of the allocation of public R&D funding is becoming particularly important when it comes to identifying the effects of state subsidies, in terms of input or output additionality. This analysis goes one important step further than the existing literature by including the time...

We use a new and exceptionally rich administrative data set for Germany to evaluate the employment effects of a variety of public sponsored training programs in the early 2000s. Building on the work of Sianesi (2003, 2004), we employ propensity score matching methods in a dynamic, multiple...

Die demografische Entwicklung in Deutschland wird auf mittlere Sicht zu einer nennenswerten Absenkung der bisher für das Gründungsgeschehen bedeutsamen Alterskohorten führen. Diese Studie zeigt durch eine Projektion der gegenwärtigen Strukturen in die Zukunft, dass die demografische...

In the European Union (EU) and in Germany the transport sector is the only sector with increasing CO2 emissions (in the EU by about 32 % and in Germany by about 1 % since 1990). Especially in road freight and air transport a further strong increase is forecasted. In the transport sector this...

This study provides insights into the effects of public R&D grants on R&D input and output of firms from Germany. Previous research has shown that the allocation of R&D project grants is rather stable regarding the pool of beneficiaries. The question is whether this participation pattern can be...

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...

Determinants of a firm's export-sales ratio (degree of internationalisation) are frequently discussed in the literature related to individual firms' export activities. Stylised facts show a positive relationship between firm size and firm age on the one hand and the firm's export-sales ratio on...
