National Economies

This paper generalizes the multi-country growth model with capital accumulation, human capital accumulation, economic structure and international trade by Zhang (2014) by making all the time-independent parameters in Zhang’s model as time-dependent parameters. Each national economy consists of one tradable, one non-tradable and one education sector. National economies are different in propensities to save, to obtain education and to consume, and in learning abilities. The model integrates the Solow growth model, the Uzawa two-sector growth model, the Uzawa-Lucas two-sector growth model, and the Oniki–Uzawa trade model within a comprehensive framework. Human capital accumulation is through education in the Uzawa-Lucas model, Arrow’s learning by producing, and Zhang’s learning by consuming (creative learning). The behavior of the household is described with an alternative approach to household behavior. We simulated the model to demonstrate existence of equilibrium points, motion of the dynamic system, and oscillations due to different exogenous shocks.

This paper proposes a dynamic economic model of wealth accumulation and human capital accumulation with endogenous education. It is an extension of the Uzawa-Lucas model of a heterogeneous household economy with multiple ways of human capital accumulation. In addition to learning by education in the Uzawa-Lucas model (Uzawa, 1965; Lucas, 1988), we also consider Arrow?s ?learning by producing? (Arrow, 1962) and Zhang?s ?learning by consuming? (creative learning, Zhang, 2007) in the human capital accumulation equation. The economic system consists of one production sector and one education sector. Households differ in propensity to save, to obtain education, to consume, and in learning abilities. The model describes a dynamic interdependence between wealth accumulation, human capital accumulation, and division of labour with endogenous wealth and income distribution in perfect competition. We simulate the model to demonstrate the existence of equilibrium points and the motion of the dynamic system. We also demonstrate how changes in the propensity to obtain education, the population, the propensity to save, and the education sector?s total productivity affect economic development.

Long Run

This study explores the growth and welfare effects of monetary policy in a scale-invariant Schumpeterian growth model with endogenous human capital accumulation. We model money demand via a cash-in-advance (CIA) constraint on research and development (R&D) investment. Our results can be summarized as follows. We find that an increase in the nominal interest rate leads to a decrease in R&D and human capital investment, which, in turn, reduces the long-run growth rates of technology and output. This result stands in stark contrast to the case of exogenous human capital accumulation in which the long-run growth rates of technology and output are independent of the nominal interest rate. Simulating the transitional dynamics, we find that the additional long-run growth effect under endogenous human capital accumulation amplifies the welfare effect of monetary policy. Decreasing the nominal interest rate from 10% to 0% leads to a welfare gain that is equivalent to a permanent increase in consumption of 2.82% (2.38%) under endogenous (exogenous) human capital accumulation.

And Gender

Abstract This paper is mainly concerned with relationships between economic growth and gender discrimination in labor markets and education. Although discrimination in different fields has well been addresses and modelled in the economic literature, there are only a few growth models with endogenous wealth and human capital accumulation, gender time distribution between work, leisure and education under gender (positive or negative) discrimination. The production and economic structures, human capital accumulation are based on the Uzawa-Lucas model, while the utility function and gender division of labor, leisure time and study time are based on the model by Zhang. The model takes account of learning by education in modeling human capital accumulation. We simulate the model to demonstrate the existence of equilibrium points and motion of the national economy. We also conduct a comparative dynamic analysis in regard to changes in discrimination in the education sector, women’s propensity to stay at home, women’s propensity to receive education, women’s knowledge utilization efficiency, and the propensity to save.

Central Hypothesis

This paper describes a growth model with the property that human capital accumulation can account for all observed growth. The model is shown to be consistent with evidence on individual productivities as measured by census earnings data. The central hypothesis is that we learn more when we interact with more productive people.
