Income Distribution and Economic Growth in a Multi-Sectoral Kaleckian Model

This study builds an income distribution and growth model within a simple multi-sectoral Kaleckian framework. The model has heterogeneous features in each sector in that the responses of saving and investment to changes in macroeconomic performance differ sectorally, and there are also different sectoral shares of saving and investment. We consider the determinants that establish the economic growth regime (i.e. wage-led and profit-led) and the stable output growth rate adjustment within this framework. By doing so, we reveal the sectoral composition of saving and investment and that elasticity of saving and investment matter for the formation of a growth regime and the stability of the output growth rate at the aggregate level.
