Bernard C. Beaudreau, H. Douglas Lightfoot The physical limits to economic growth by R&D funded innovation, Energy 84 (May 2015) : 45–52.

Do R&D-based models of growth predict scale effects?

This paper argues that the “scale effects” prediction of many recent R & D-based models of growth is inconsistent with the time-series evidence from industrialized economies.

What are the basic models of economic growth?

In this article, we discuss some basic models of economic growth which lay the foundation for any comprehensive study of the process of economic development. The aggregate production function lies at the heart of every model of economic growth. It is also an extension of the micro-economic production function’ at the national or economy wide level.
