Environmental policy affects the distribution of market shares if intermediate goods are differentiated in pollution intensity. When innovations are environmental friendly, a tax on emissions skews demand towards new goods, which are the most productive. In this case along a balanced growth path...

This paper explores the trade-off between economic growth and environmental quality along two paradigms of endogenous growth theory: variety expansion (HIP) and quality improvements (VIP). We compare the policies that match the decentralised economies' paths with the optimal "strong sustainable"...

This paper argues that growth theory needs a more general notion of 'regularity' than that of exponential growth. We suggest that paths along which the rate of decline of the growth rate is proportional to the growth rate itself deserve attention. This opens up for considering a richer set of...

The conventional view within the endogenous growth literature is that interest income taxes impede economic growth and investment subsidies promote economic growth. The present paper lays out a simple framework to see whether this is still true when non-renewable resources enter the "growth...

Conventional endogenous growth theory relies on the assumption of constant returns to "broad capital". As Solow pointed out, the strength of this assumption is revealed by recognizing that even the slightest touch of increasing returns creates explosive growth: infinite output in finite time!...
