Structural transformations and cumulative causation towards an evolutionary micro-foundation of the Kaldorian growth model

Abstract

We derive the Kaldorian cumulative causation mechanism as an emergent property of the dynamics generated by a micro-founded model. We build on an evolutionary growth model which formalises the endogenous relations between structural changes in the production, organisation and functional composition of employment and of consumption patterns (originally proposed by Ciarli et al, 2010). We discuss the main transition dynamics to a self- sustained growth regime in a two-stage growth pattern generated through the numerical simulations of the model. We then show that these mechanisms lead to the emergence of a Kaldor-Verdoorn law. Finally we show that the structure of demand shapes the type of growth regime emerging from the endogenous structural changes, fostering or hampering the emergence of the Kaldor Verdoorn law. This depends on the endogenous income distribution and heterogeneity in consumption behaviour
