Solow Growth Model | Part 1 | Model Intro & Solution | Intermediate Macroeconomics

In this video, I introduce a baseline version of the Solow growth model. The baseline model does not account for population growth or technological progress.

There are four primary equations for this version of the Solow model: the production function, capital accumulation, the resource constraint, and resource allocation (investment equals savings). I explain these equations in detail, then I rewrite them in per capita form. Writing the Solow model in per capita terms is useful, especially once population growth is introduced into the model.


The solution is a path for the endogenous variables of the model. I also present a numerical solution to the model using Matlab. Feel free to replicate my code and try it yourself.
