An AB-SFC Model of Induced Technical Change along Classical and Keynesian Lines

This paper introduces the classical idea about the so-called directed and induced technical change (ITC) within a Keynesian demand-side and evolutionary endogenous growth model in order to analyze the interplay among technical change, long-run economic growth and functional income distribution. An ITC process is analyzed within an Agent-Based Stock-Flow Consistent (AB-SFC) model, wherein credit-constrained heterogeneous firms choose both the intensity and the direction of the innovation towards a labor- or capital-saving choice of technique. In the long-run, the model reproduces the so-called Kaldor stylized facts (i.e. with a purely labor-saving technical change), however during the transitional phase the model shows a labor-saving/capital-using innovation pattern, as the aggregate output-capital ratio decreases until it stabilizes in the long-run, as well as declining labor share for long time periods and we can ascribe these evidences mainly to the directed technical change process. In order to stress the effective role of the innovation bias on the model dynamics, we compare the baseline scenario with a counterfactual scenario wherein a neutral technical progress is at work.
