Interest , debt and capital accumulation - a Kaleckian approach
نویسنده
چکیده
In the present paper we explicitly introduce interest payments and debt into a Kaleckian distribution and growth model with an investment function very close to Kalecki’s original writings. The effects of interest rate variations on the short-run equilibrium values of capacity utilisation, capital accumulation and the rate of profit are derived, and the long run effects on the equilibrium debt-capital-ratio are also analysed. It is shown, that the effects of interest variations on the endogenously determined equilibrium values of the model do not only depend on the parameter values in the saving and investment functions but also on the interest elasticity of distribution and in some cases on initial conditions with respect to the interest rate and the debt-capital-ratio. If the conditions for short-run ‘normal’ effects of interest rate variations are given, the economy will be characterised by a long-run unstable debt-capitalratio and by the macroeconomic ‘paradox of debt’. These results are similar to other models and hint to the robustness of Kaleckian ‘monetary’ models of distribution and growth with respect to the specification of the investment function.

Income Distribution, Debt Accumulation, and Financial Fragility in a Kaleckian Model with Labor Supply Constraints
This paper investigates the effect of changes in the retention ratio, profit share, interest rate, and natural rate of growth on the rate of capital accumulation and the financial structure of firms by using a Kaleckian growth model with labor supply constraints. We show that if the economy exhibits a debt-burdened regime, depending on certain conditions, there could be cyclical fluctuations su...

In this study, using the overlapping generation (OLG (model and the Stochastic Dynamic General Equilibrium (DSGE) approach, the optimal form of labor income tax rate and capital income tax functions is extracted for the economy of Iran using annual time series data during 1357 to 1397. The results of comparing the calibration and simulation of the designed model show that the optimal functions ...
متن کاملTheoretical and empirical shortcomings of the Kaleckian investment function
The speci cation of the accumulation function is critical for the properties and implications of structuralist and post-Keynesian models. A large Kaleckian literature assumes that investment is relatively insensitive to variations in the utilization rate of capital, and this extension of a standard short-run "Keynesian stability condition" to the long run has been defended by Lavoie and Dutt, a...
متن کاملFinancialization and its Long-run Macroeconomic Effects in a Kalecki-Minsky Model
One of the main characteristics of “financialization” is the redistribution of income in favor of shareholders, at the expense of workers. In this paper, we interpret pro-shareholder redistribution as a decrease in both retention ratio and wage share. Using both the Kaleckian macroeconomic model and the Minskyan taxonomy of finance regime, we investigate the long-run effects of such parametric ...
