Capital Accumulation, Technological Progress and Environmental Change in a Three-Sector Growth Model

Author(s):

This paper builds a dynamic growth model with wealth accumulation, technological change, and environmental change on the basis of the neoclassical growth theory with an alternative approach to household behavior. The model synthesizes the economic growth mechanism in the neoclassical growth theory, Arrow’s learning-by-doing, and the environmental change in some traditional dynamic models of environmental economics. It describes a dynamic interdependence among wealth accumulation, technological change, and environmental change under perfect competition with environmental taxes. The author simulated the model to demonstrate existence of equilibrium points and motion of the dynamic system. In particular, the author demonstrated effects of changes in the government policy and preference upon both short-run and long-run economic behavior of the system.

The purpose of this study is to introduce monopolies to neoclassical growth theory. This unique contribution attempts to make neoclassical economic growth theory more realistic in modelling the complexity of economic growth and development with different types of market structures. This study is based on a few well-established economic theories in the literature of economics. We frame the model on basis of the Solow–Uzawa two-sector growth model. The modelling of monopoly is based on well-developed monopoly theory. We model behavior of the household with Zhang’s concept of disposable income and utility function. The model endogenously determines profits of monopolies which are equally distributed among the homogeneous population. We build the model and then identify the existence of an equilibrium point by simulation. We conduct comparative static analyses in some parameters.

Abstract This paper is concerned with relationship between growth and land value change. It builds a heterogeneous-households growth model with endogenous wealth accumulation and fixed nondepreciating asset (land) in an integrated Walrasian general equilibrium and neoclassical growth theory. The production side consists of one service sector and one industrial sector. We use an alternative utility function proposed by Zhang, which enable us to develop a dynamic growth model with genuine heterogeneity. The wealth and income inequality is due to household heterogeneity in preferences and human capital as well as the households’ initial wealth. This is different from the standard Ramsey-type heterogeneous-households growth models, for instance, by Turnovsky and Garcia-Penalosa (2008), where agents are heterogeneous only in their initial capital endowment, not in preference or/and human capital. We build a model for any number of types of household and provide a computational procedure for simulating model. For illustration we simulate the model for the economy with three types of households. We simulate the motion of the national economy and carry out comparative dynamic analysis. The comparative dynamic analysis provides some important insights. For instance, as the rich group increases its propensity to save, the GDP and land value are increased. In the long term the group accumulates more wealth, consumes more goods and services and accumulates more wealth. But in the long term the other two groups suffer from the rich households’ preference change as their lot sizes, consumption levels of services and goods, and wealth are all reduced.

Wealth accumulation is a deterministic factor mechanism of national economic growth. Neoclassical growth theory is basically concerned with capital and wealth accumulation in perfectly competitive market. Global markets are characterized by a great variety of markets. Nevertheless, there only a few rigorous models of wealth accumulation with other types of markets within neoclassical growth framework. This study attempts to contribute literature of economic growth by introducing monopolistic competition and monopoly into neoclassical growth theory. The model is based on a few well-established economic theories. The model is constructed within framework of the Solow-Uzawa two-sector neoclassical growth model. The description of to monopolistic competition is influenced by the Dixit-Stiglitz model of monopolistic competition. The modelling of monopoly is based on monopoly theory. We model behavior of the household with Zhang’s utility function and concepts of current income and disposable income. The unique contribution of this research is to integrate these theories in a comprehensive framework. We construct the basic model and then analyze properties of the model. The existence of a unique equilibrium point is identified by simulation. The effects of changes in some parameters comparative static analyses in some parameters.

One of the relevant components of the contemporary economic science is the economic growth theory, the economic background of the time leading to new guidelines of the research. The neoclassical growth theory - the core of modern analysis - explains how the capital accumulation and technological changes affect the economy, significant for the analysis of the economic growth process being the Solow’s neoclassical growth model. The paper brief describes the elements of the economic growth model developed by Solow, both for the situation when it allows the explanation of extensive growth and that wherein the growth is of intensive nature, as a result of the intervention of exogenous technical progress – a determinant of factors productivity growth. It is highlighted the importance of the exogenous neoclassical model, proposed by Solow, who showed the determinant role of the technical progress in the economic growth phenomenon.

<p>This paper generalizes the dynamic growth model with interactions between fashion, economic growth and income and wealth distribution recently built by Zhang (2016). The modelling of fashion and preference change is inspirited by the economic model of fashion recently published by Giovinazzo and Naimzada (2015). This study introduces fashion into neoclassical growth theory. The original model is based on some ideas in the literature of economics of fashion. This study generalizes Zhang’s model by making all the time-independent parameters as time-dependent parameters. We simulate the motion of the economic system. We carry out comparative dynamic analysis with regard to periodic perturbations in some parameters. We show how exogenous period changes in these parameters lead to business cycles. </p>

Abstract This paper studies dynamic interdependence of capital, land and resource values in a three sector growth model with endogenous wealth and renewable resources. The model is based on the neoclassical growth theory, Ricardian theory and growth theory with renewable resources. The household’s decision is modeled with an alternative approach proposed by Zhang two decades ago. The economic system consists of the households, industrial, agricultural, and resource sectors. The model describes a dynamic interdependence between wealth accumulation, resource change, and division of labor under perfect competition. We simulate the model to demonstrate the existence of a unique stable equilibrium point and plot the motion of the dynamic system. The study conducts comparative dynamic analysis with regard to changes in the propensity to consume resources, the propensity to consume housing, the propensity to consume agricultural goods, the propensity to consume industrial goods, the propensity to save, the population, and the output elasticity of capital of the resource sector.

The numerous versions of endogenous explanations of economic growth emphasize the importance of technological change driving forces, as well as the existence of appropriate institutional arrangements. Endogenous growth theory contributes to a better understanding of various experiences with long-term growth of countries and regions. It changes the key assumptions of the Neoclassical growth theory and participates in the modern regional development physiology explanation. Based on these conclusions, the paper: a) explicates the most important theoretical postulates of the theory, b) explains the most important factors of economic growth in the regions in light of the Endogenous growth theory messages and c) emphasizes the key determinants of regional competitiveness which in our view is conceptually between the phenomena of micro- and macro-competitiveness and represents their necessary and unique connection. First of all, micro-competitiveness is transformed into a regional competitiveness; then regional competitiveness is transformed into a macro-competitiveness. In turn, macro - influences the microeconomic competitiveness, and the circle is closed. After that, the process starts over again.
