The recurrent issues of "non-robustness" and "scale effects" are discussed within a unified framework for the presentation of different generations of innovation-based growth models. With a certain proviso robust innovation-based growth models tend to end up with the long-run per capita growth...

This paper takes an AK model to the PWT data. In the model, intratemporal and intertemporal shocks are reduced forms for different technologies, and determine the variation of the growth rate. Using the policy functions of the model we recover time series for the unobserved technology shock for...

There appears to be ample evidence that the size of population acted as a stimulus to growth in historical times; scale mattered. In the post World War II era, however, there is little evidence of such scale effects on growth. Where did the scale effect go? The present paper shows that the...

This article reviews issues related to the incorporation of non-renewable resources in the theory of economic growth and development. As an offshoot of the new growth theory of the last two decades a series of contributions have studied endogenous technical change in relation to resource...

We take an AK model to the PWT data. In the model both technology (intratemporal) and investment (intertemporal) shocks determine the variation of the growth rate. In earlier work we looked at singular models where we extracted only the technology shock using the policy functions from dynamic...
