Empirical research has affirmed such a relationship and have found that the Kaldor-Verdoorn coefficient lies between 0 and 1. But the interpretation of this finding remains unclear. In this paper, we present a model to derive the Kaldor-Verdoorn law. Our results show that the Kaldor-Verdoorn coefficient is jointly determined by the elasticity of factor substitution, labor supply elasticity, the profit share and the increasing returns to scale (or demand-induced technical …
