Place in order the events in the evolution of the Solow growth model.
The Solow growth model was developed in 1956. The Solow model was applied to many African nation that had just gained independence. Growth policies failed; nations that had received international aid were no better off. Real-world observations caused economists to revisit the Solow growth model.
When technological advances occur in an economy, the production function is changed because capital becomes more productive.

What are some of the main elements of the original Solow growth model?
Over time, per capita GDP will equalize across nations. An increase in the capital stock will result in growth. Investment in poorer nations should yield relatively higher returns. Growth will stop when nations reach their steady state.
