O modelo de ciclo econômico de Kalecki

Abstract

This article presents a formal analysis of the business cicle models put forward by Kalecki in the two most familiar versions of 1933 and 1954. After a short comment on the economic content of these models, they are expounded and interpreted mathematically as a solution of 2nd order difference equations with constant coefficients. With a view to making it easier for the reader a comparison with Kalecki's original theoretical formulations, his assumptions, terminology and notation have been kept throughout. A brief analysis follows dealing with the effects of different sectoral growth rates on the macroeconomic distribution of income, which are not focused in aggregate cycle models, based on Kalecki's 3-sector scheme. Concluding observations are made on the relations between trend and cycle and on the perspectives of further theoretical effort in this field.
