This paper investigates the relationship between public debt and economic growth in the context of a panel kink regression with latent group structures. The proposed model allows us to explore the heterogeneous threshold effects of public debt on economic growth based on unknown group patterns....

The Ramsey (1928) equation decomposes the real discount rate into the pure rate of time preference plus a term that accounts for the changing marginal utility of consumption. Discussions about the appropriate discount rate to apply in Cost Benefit Analysis sometimes refer to variations induced...

We use a model of endogenous growth with vertical innovations, in order to derive optimal energy policy under uncertainty. Innovation can be directed to dirty, green, or nuclear technologies, which in turn can be used to produce different types of energy. We show that, nuclear energy usage, is...
