Endogenous Economic Growth: The Arrow-Romer Theory and a Test on Vietnamese Economy
Author:
Abstract: The Arrow-Romer growth model helped to overcome the main drawback of the Solow-Swan model, where technical change is created exogenously, not by the firms making decisions, and formulated the conditions for endogenous growth in an economy. Nonetheless, the presentation of the Arrow-Romer model and corresponding empirical studies by the Cobb-Douglas functions hides the role of the capital-labor relationship for economic growth. A constant elasticity of substitution (CES) function, constructed by Arrow et al. (1961), allows solving this problem. So, the purpose of the current research is to test the endogenous growth of the Vietnamese economy, which has experienced a more than 30-year market-oriented reform through specifying an aggregate CES function. By applying Bayesian nonlinear regression, the research results revealed the elasticity of factor substitution (ES) lower than one. This work theoretically and empirically contributes to the endogenous growth theory in problems concerned with emerging economies. Investments in physical and human capital and technological progress are the determinants of endogenous growth. From the findings obtained, the author concludes that even though having achieved a rather impressive growth rate over more than three decades, the Vietnamese economy has not yet generated the possibility of endogenous growth, and suggests that endogenous growth can be hardly generated in emerging economies like Vietnam if important growth policies related to accumulation of physical and human capital as well as enhancement of R&D activities are not simultaneously implemented. It is indispensable to focus on substantially improving institutional quality.
