This paper shows that observations generated from a technology with fixed coefficients can be approximated well by a Cobb-Douglas function with constant returns-to-scale. The approximation is shown to ...

Rearranging Equation , we can derive the basic Cobb-Douglas formulation for labour and capital, times energy inputs.

Many growth models assume that aggregate output is generated by a Cobb-Douglas production function. In this article we question the empirical relevance of this specification. We use a panel of 82 ...
