We introduce a minimal notion of altruism and use it to refine Nash equilibria in normal form games. We provide three independent existence proofs, relate minimally altruistic Nash equilibrium to other equilibrium concepts, conduct an in-depth sensitivity analysis, and provide examples where...

We study the effects of energy saving technological progress and substitution of renewable energy resources with non-renewable resources on natural resource depletion and long run growth. We develop a growth model in two-period overlapping generations framework incorporating the presence of both...

Presenting a discrete time version of the Romer (1986) model, this paper analyzes optimal paths in a one-sector growth model when the technology is not convex. We prove that for a given quality of knowledge technology, the countries could take-off if their initial stock of capital are above a...
