This paper presents an economic growth model based on the positive externalities generated by the accumulations of physical and human capital. Such externalities imply, at the macroeconomic level, increasing returns to scale. The model helps to better understand the Colombian economic growth process from 2005-2019, and make conditional forecasts. One of the big obstacles in Colombia to have higher growth rates of the per capita product in the long term is everything that is slowing down a higher human capital growth rate and a greater creation of externalities derived from human capital, that is, everything that is hindering improvements in coverage and quality of the educational process.
