| Summary/Abstract |
This paper investigates the intensity of international collaborations in energy-related technologies across OECD and BRIICS countries, by disentangling the role of the distance in environmental policy stringency between countries, controlling for the more traditional measures of technological, social, institutional and geographical distance. In doing so, it distinguishes between the stringency in demand-pull and the stringency in technology-push policy instruments. The analysis relies upon an original dataset, with data on patents and co-patents in climate change and mitigation technologies over the period 1995–2014, with a focus on technologies related to energy generation, transmission or distribution. The results show that the distance in the stringency of environmental policy between countries hinders the intensity of technological collaborations in energy-related technologies and this occurs specifically with reference to demand-pull policy instruments. We also find that while the availability of local technological capabilities positively affects the intensity of international collaborations, if two countries are distant in terms of technological development, the co-patenting activity is hindered. Finally, BRIICS countries display a lower ability to participate in international co-patenting activity, particularly so in collaboration with other BRIICS countries.

| Summary/Abstract |
This paper analyses the factors explaining the recent boost in solar energy private investments, focusing on the role of public finance and public policy tools - feed-in-tariffs and renewable energy quotas. Drawing on a micro-level database of financial transactions in solar energy projects in 23 OECD countries over the period 2004–2015, we perform a panel data analysis to study the relationship between public finance and public policies and private investments in solar energy, controlling for composition of the energy industry and market characteristics by country. We find that the provision of public finance is positively associated with private finance flows. Furthermore, we show that public policy stimulates private investments, but the effect of renewable energy quotas on private finance is larger than that of feed-in tariffs. Finally, the availability of fossil fuels constitutes an important barrier to solar energy investments, while the presence of alternative sources of clean energy does not hinder private climate finance.
