Abstract 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...

This paper argues that growth theory needs a more general "regularity" concept than that of exponential growth. This offers the possibility of considering a richer set of parameter combinations than in standard growth models. Allowing zero population growth in the Jones (1995) model serves as...

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...

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...
