According to the consensus view, it was primarily physical capital accumulation that drove economic growth during the early years of state socialism. Growth models incorporating both human and physical capital accumulation led to the conclusion that a high physical/human capital ratio can cause a lower economic growth in the long run, hence offering an explanation for the failure of socialist economies. In this paper, we show theoretically and empirically that according to the logic of the socialist planner, it was optimal to achieve a higher physical to human capital ratio in socialist countries than in the West. Using a VAR analysis, we find empirical confirmation that within the Material Product System of national accounting, the relative dominance of investment in physical capital accumulation relative to human capital was indeed more efficient than under the system of national accounts.

Accumulation of human capital is critical to sustained economic growth in the long run, since it facilitates the efficient absorption of new capital developments, improves the speed of adaptation of entrepreneurs and generates innovation necessary for sustained economic growth. It is against this premise this study investigate the human-capital accumulation growth-nexus in Nigeria. Employing a dynamic approach, involving test for unit roots, and cointegration, and finally, the Generalized Method of Moments (GMM) estimation techniques on annual time series data, covering the period 1981 to 2016, sourced from the World Bank Development Indicators (WDI) and Central Bank of Nigeria (CBN) Statistical Bulletin, the empirical findings reveal that human and physical capital accumulation significantly induce rapid and sustained economic growth in the long-run. The other variables- infrastructural development (measured by ICT infrastructure) and industrial output (a measure of industrialization) have positive but weak impacts on economic growth, on account of the weak infrastructural development, and low level of industrialization in Nigeria. Inflation rate (a measure of macroeconomic policy environment) on the other hand, is found to have a militating effect on economic growth. We recommend amongst others; sustained investments in human and physical capital accumulation, stable and coherent macroeconomic policies, particularly with respect to taming of domestic inflationary pressures, supportive institutional structures and aggressive industrialization-enhancing policies, in order to enhance sustained economic growth in Nigeria.

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.

We investigate a spatial economic growth model with bounded population growth to obtain the asymptotic behavior of detrended capital in a continuous space. The formation of capital accumulation is expressed by a partial differential equation with corresponding boundary conditions. The capital accumulation interacts with the morphology to affect the optimal dynamics of economic growth. After redrafting the spatial growth model in the infinite dimensional Hilbert space, we identify the unique optimal control and value function when the bounded population growth is considered. With nonnegative initial distribution of capital, the explicit solution of the model is obtained. The time behavior of the explicit solution guarantees the convergence issue of the detrended capital level across space and time.

This article explores the relationship between financial sector development and economic growth, using a sample of ASEAN-5 countries (Malaysia, Indonesia, Singapore, Thailand and Philippines) from 1980 to 2011. More specifically, this study investigates whether higher levels of financial development (FD) are significantly and robustly correlated with faster current and future rates of economic growth, physical capital accumulation and economic efficiency improvements. Findings of this study revealed that FD has a significant positive effect on economic growth. However, the estimated models show that the influence of FD, as a determinant for economic growth of ASEAN-5 countries, is less than that of domestic investment and export.

Abstract In a Ramsey model of optimal taxation, if human capital investment can be observed separately from consumption, it is optimal not to distort human or physical capital accumulation in the long run, and only labour income taxes should be used. However, in reality the government can’t always distinguish between investment in human capital and pure consumption, so a tax on labour or consumption will necessarily tax human capital. We find that when investment in human capital is unobservable, the optimal policy is to tax human capital at a positive rate, even in the long run. Whether physical capital should be taxed or not depends on its degree of complementarity with human capital versus labour.

Abstract Using a growth model with physical capital accumulation, human capital investment and horizontal R&D activity, this paper proposes an alternative channel through which an increase in the population growth rate may yield a non-uniform (i.e., a positive, negative, or neutral) impact on the long-run growth rate of per-capita GDP, as available empirical evidence seems mostly to suggest. The proposed mechanism relies on the nature of the process of economic growth (whether it is fully or semi-endogenous), and the peculiar engine(s) driving economic growth (human capital investment, R&D activity, or both). The model also explains why in the long term the association between population growth and productivity growth may ultimately be negative when R&D is an engine of economic growth.

The authors present and test a theory about the effects of political competition on the sources of economic growth. Using Mankiw, Romer, and Weil’s model of economic growth and data for roughly 80 countries, the authors show that political competition decreases the rate of physical capital accumulation and labor mobilization but increases the rate of human capital accumulation and (less conclusively) the rate of productivity change. The results suggest that political competition systematically affects the sources of growth, but those effects are cross-cutting, explainingwhy democracy itself may be ambiguous. These findingshelp clarify the debate about regime type and economic performance and suggest new avenues for research.
