This paper examines the impact of Knightian uncertainty upon optimal climate policy through the prism of a continuous-time real option modelling framework. We analytically determine optimal intertemporal climate policies under ambiguity. Additionally, numerical simulations are provided to...

This paper investigates the relative economic and environmental outcomes of price versus quantity mechanisms to control GHG emissions when abatement costs are uncertain. In particular, we evaluate the impacts on policy costs, CO2 emissions and energy R&D for a stringent mitigation target of 550...

This article summarises our studies on the optimal timing of climate policy adoption by focusing on ambiguity in the climate damage cost assessments (Chen et al., 2011) and on the limited time to achieve certain climate policy targets (Chen et al., 2012). Using real options theory, both studies...
