Economic growth, increasing results and monopolist competition

ABSTRACT In this article we investigate the theoretical shortcomings of traditional neoclassical growth models and how the new literature of endogenous growth has emerged to overcome these shortcomings. We study the theoretical reasons for hypothesis in the traditional models - some of them necessary for the existence of equilibrium - that implied counter-factual empirical results, like convergence. We will investigate how these hypotheses were relaxed or substituted, up to a point where the new literature ends up working with increasing returns and monopolist competition models of Schumpeterian inspiration that deliver sustained growth and creative destruction.
