Global warming can be curbed by pricing carbon emissions and thus substituting fossil fuel with renewable energy consumption. Breakthrough technologies (e.g., fusion energy) can reduce the cost of such policies. However, the chance of such a technology coming to market depends on investment. We...

Carbon pricing is a central part of climate policy, but is politically difficult while the economy is still reliant on fossil fuels. The long-lived green investments required to break the carbon lock-in depend on expected taxes, not current taxes. Policies which target the expectations of the...

Mitigating climate change by carbon capture and storage (CCS) will require vast infrastructure investments. These investments include pipeline networks for transporting carbon dioxide (CO2) from industrial sites ('sources') to the storage sites ('sinks'). This paper considers the decentralised...

I explain the recent peak and subsequent collapse in oil prices by strategic interaction between a limit-pricing oil cartel and an importer producing substitutes to oil, with productin costs falling with R&D investment. The model is consistent with reported narratives of the oil price collapse....
