Solow Growth Model
Also called: Solow model, neoclassical growth model, growth accounting
The Solow model explains long-run growth through capital, labour and technology, and its central result is uncomfortable for policy: because capital has diminishing returns, saving and investing more raises the level of income but not its permanent growth rate. Only technological progress does that, and the model treats it as exogenous — a gap that motivated the endogenous growth theories that followed.
