Green accounting theories have shown that negative genuine savings at some point in time imply unsustainability. Consequently, recent studies advocate the use of the genuine savings measure for empirical testing: a negative index implies sustainability be rejected. This criterion is not...

We analyze the consequences of habit formation for income levels and long-term growth in an overlapping generations model with dynastic altruism and resource dependence. If the strength of habits is below a critical level, the competitive economy displays an altruistic (Ramsey-like) equilibrium...

We study a two-phase endogenous growth model in which the adoption of a backstop technology (e.g. solar) yields a sustained supply of essential energy inputs previously obtained from exhaustible resources (e.g. oil). Growth is knowledge-driven and the optimal timing of technology switching is...

An established result of the endogenous growth literature is that competitive equilibria in expanding-varieties models are suboptimal due to the rent-effect: monopolistic pricing drives the equilibrium quantity of each intermediate below the efficient level, implying that it is optimal to...

This paper studies the effects of distortionary taxes and public investment in an endogenous growth OLG model with knowledge trans- mission. Fiscal policy affects growth in two respects: first, work time reacts to variations of prospective tax rates and modifies knowledge formation; second,...

The interaction between habit formation and pollution-type ex- ternalities modifies the social optimum through discount effects and elasticity effects. If the substitution elasticity does not exceed unity, both effects reduce optimal consumption and capital in the long run, and the optimal...
