Abstract Even more than eight decades since the publication of Keynes’ “General Theory of Employment, Interest, and Money” modern macroeconomists disagree on the notion of “underemployment equilibrium” with so-called “involuntary unemployment”. While the majority of macro theorists trace involuntary unemployment back to frictions and rigidities in the adaptation of wages and output prices to market imbalances, a minority position holds that even under perfectly flexible output prices and wage rates involuntary unemployment might occur. Morishima in “Walras’ Economics” and more recently Magnani presume that contrary to the majority view aggregate investment is not perfectly flexible but governed by “animal spirits” of investors. The aim of the present paper is to integrate the Morishima-Magnani approach into a Diamond-type overlapping generations’ (OLG) model with internal public debt subsequently extended by human capital accumulation. It turns out that in spite of perfectly flexible real wage and interest rate involuntary unemployment occurs in intertemporal general equilibrium when aggregate investor sentiments are too pessimistic regarding the rentability of investment in real capital. In the model extended by human capital a higher public debt to output ratio decreases unambiguously involuntary unemployment, if initially the endogenous output growth rate is higher than the real interest rate.

Special Case

В статье рассматривается модель эндогенного роста с человеческим капи-талом на простой пространственной структуре (окружности). Особое вни-мание уделено специальному случаю - комбинации параметров, при кото-рой удаётся получить решение задачи центрального планировщика на окружности в явном виде, что другим авторам не удавалось. In this article the endogenous growth model with human capital on the simple spatial structure (the circle) is considered. We pay main attention to a special case of a combination of parameters for which we were able to solve the central plan-ner problem on the circle in an explicit form, which other authors did not suc-ceed to do.

Main Engine

This paper proposes a one-sector multigroup growth model with endogenous labor supply in discrete time. Proposing an alternative approach to behavior of households, we examine the dynamics of wealth and income distribution in a competitive economy with capital accumulation as the main engine of economic growth. We show how human capital levels, preferences, and labor force of heterogeneous households determine the national economic growth, wealth, and income distribution and time allocation of the groups. By simulation we demonstrate, for instance, that in the three-group economy when the rich group's human capital is improved, all the groups will economically benefit, and the leisure times of all the groups are reduced but when any other group's human capital is improved, the group will economically benefit, the other two groups economically lose, and the leisure times of all the groups are increased.

The paper is concerned with the dynamic interactions between physical capital, human capital, income and wealth inequalities between different households with government subsidy to education. It generalizes the endogenous growth model of a small-open economy proposed by Zhang (2016). Zhang’s paper deals with income and wealth inequalities between heterogeneous households with government subsidy to education. The paper makes a contribution to the literature of economic growth with endogenous education by integrating Solow-Uzawa’s neoclassical growth theory, Uzawa-Lucas model, Arrow’s learning by doing, Zhang’s creative leisure, and Walrasian general equilibrium theory. The model treats endogenous capital and human capital accumulation as the main engines of economic growth. This study generalizes Zhang’s model by allowing constant coefficients to be time-dependent. We simulate the generalized model to demonstrate existence of business cycles due to various exogenous periodic shocks.
