Abstract: Using an optimal control model, we explore the reaction of a firm|s optimal investment into an R&D program that aims at non-carbon technologies under uncertainties about a future carbon tax. We find; first, that the influence of risk on investment decisions depends on model formulation. Second, near-term investments decrease in risk in the magnitude of a carbon tax, but increase in uncertainty in the timing of a carbon tax.
Keywords: policy uncertainty; carbon tax; research and development; R&D investment; energy investment; optimal control modelling; non-carbon technologies; investment risk; investment decisions.
