This paper concerns optimal emissions of greenhouse gases when catastrophic consequences are possible. A numerical model is presented which takes into account both continuous climate-feedback damages as well as the possibility of a catastrophic outcome. The uncertainty in the model concerns...

Environmental policies frequently target the ratio of dirty to green output within the same industry. To achieve such targets the green sector may be subsidised or the dirty sector be taxed. This paper shows that in a monopolistic competition setting the two policy instruments have different...

Model uncertainty is inherent in the design of optimal environmental policy. We investigate the consequences in a simple linear model, where the aim of the policymaker is to stabilize the carbon content of the atmosphere. We study how decision-makers' concerns about robustness alter policy using...
