The model was developed by Robert Solow in the 1960s and it is sometimes called the Solow growth model or the exogenous growth model. EXOGENOUS AND ENDOGENOUS GROWTH Neo-classical theory, in all its forms, shows a strong tendency to reduce the economic complexity of the analysis, doing so by holding the institutional framework constant. This is the main di/erence between the Solow model and the neoclassical growth model.

Such accumulation continues until the stage of unconditional convergence as diminishing marginal returns to capital set in. The author uses detailed formulas and calculations to also illustrate Ricardian Equivalence, an economic theory which suggests that the government can finance spending with either public debt or tax increase, as market demand and spending will remain the same in either case.
