Abstract
We estimate schedules of declining discount rates for cost benefit analysis in the UK. We highlight
the importance of model selection for this task and hence for the evaluation of long-term investments,
namely climate change prevention and nuclear build.
JEL classification: C13, C53, Q2, Q4
Keywords: long-run discounting, state-space models, regime-switching models, climate change policy,
nuclear build
