Green innovation is essential for climate change mitigation, but not all innovative projects deliver equal social value. We consider innovator heterogeneity in a model where the policy maker cannot observe innovation quality and directly subsidize the socially most valuable green innovations. We...

We consider technology choices between green and brown technologies by firms. We use insights from complexity theory and also take account of true uncertainty in designing public policy. The green technology offers relatively higher returns to scale from adoption, and there are type-contingent...

In the US and many other OECD countries, expenditures for defense-related R&D represent a key policy channel through which governments shape innovation, and dwarf all other public subsidies for innovation. We examine the impact of government funding for R&D - and defense-related R&D in...

We examine how Green governments influence macroeconomic, education, and environmental outcomes. We exploit that the Fukushima nuclear disaster in Japan gave rise to an unanticipated change in government in the German state Baden-Wuerttemberg in 2011. Using the synthetic control method, we find...

Current policy initiatives taken by the EU and the OECD aim at abolishing preferential corporate tax regimes. This note extends Keen's (2001) analysis of symmetric capital tax competition under preferential (or discriminatory) and non-discriminatory tax regimes to allow for countries of...

This paper studies empirically the effect of education policies on human capital and per capita income. The results suggest for European and OECD countries that higher attendance at pre-primary education, greater autonomy of schools and universities, a lower student-to-teacher ratio, higher age...

In June 2018, an agreement between key EU institutions – the Commission, the European Parliament, and the European Council – was reached after a long-lasting discourse over the 2030 EU climate and energy policy package. This paper offers a comprehensive assessment of the EU package, with its...

It has long been argued that the implementation of market-based environmental policy instruments such as environmentally-related taxes and tradable permits is likely to lead to greater technological innovation than more direct forms of regulation such as technology-based standards. One of the...

Conventional wisdom argues that environmental policy is less costly if environmental policy induces the development of cleaner technologies. In contrast to this argument, we show that the cost of environmental policy (a reduction in emissions) may be larger with induced technical change than...

In response to the global crisis a number of new institutional measures have been introduced in the fiscal framework, both on the UE and on the member states’ level, and the question is: have these measures provided better fiscal sustainability outcomes? We approach this question by looking at...
