Answer: (c) Capital per effective worker.
Explanation:
What is Solow Model? The Solow Growth Model is an exogenous model of economic growth that analyzes changes in the level of output in an economy over time as a result of changes in the population growth rate, the savings rate, and the rate of technological progress.
The reason for this is that, in this model, both population growth and technological progress are taken into consideration. In the long run, the steady state occurs when capital per effective worker (which accounts for both population and technological progress) remains constant. This means that even if capital and capital per worker are growing, capital per effective worker remains constant in the steady state, ensuring a balanced and sustainable economic growth.
