This policy note investigates whether the current level of public support to environment-friendly technologies is sufficient to allow European countries to respond to the multiple challenges posed by climate change and other environmental concerns. We first lay out the justifications for...

Global climate change and other environmental challenges require the development of new energy technologies with lower emissions. In the near-term, R&D investments, either by government or the private sector, can bring down the costs of these lower emission technologies. However, the results of...

In a domestic market, a duopoly produces a homogeneous final good, pollution, pollution abatement and R&D. One of the firms (foreign) has superior technology. The government regulates the duopoly by levying a pollution tax to maximize domestic welfare. We consider the potential implementation of...

This article tests the effects of fuel economy and greenhouse gas emission standards on the direction of innovation, in particular on breakthrough technologies in the automotive industry. We develop an intuitive measure of standard stringency that captures the policy’s most important features...

The costs of low-carbon energy fell dramatically over the past decade, leading to rapid growth in its deployment. However, many challenges remain to deploy low-carbon energy at a scale necessary to meet net zero carbon emission targets. We argue that developing complementary technologies and...

We argue that, for a given level of scientific knowledge, tolerance and diversity are conducive to technological creativity and innovation. In particular, we show that variations in innovation within Prussia during the second industrial revolution can be ascribed to differences in religious...

We provide quantitative evidence on the relationship between military spending and innovation in the 19th century. Combining innovation data from world fairs and historical military data across Europe, we show that national military spending is associated with national innovation towards war...

Demographic change will be one of the major challenges for economic policy in the developed world in the next decades. In this article, we analyze the relationship between age structure and the number of startups. We argue that an individual's decision to start a business is determined by his or...
