This monograph benchmarks innovation policies for sustainability, focusing on two key areas: low-carbon and environmental technologies, and “smart-city” initiatives in selected OECD countries as well as the European Union. Country coverage of low-carbon technologies includes both natural...

We derive the optimal contributions to global climate policy when countries differ with respect to income level and pollution intensity. Countries' growth rates are determined endogenously, and abatement efficiency is improved by technical progress. We show that country heterogeneity has a...

The paper considers a climate change growth model with three R&D sectors dedicated to energy, backstop and CCS (Carbon Capture and Storage) efficiency. First, we characterize the set of decentralized equilibria: A particular equilibrium is associated to each vector of public tools which includes...
