📌 The Solow model cannot analyze the efficiency of different growth paths or compare welfare between steady states because its saving rate is exogenous.
1. Why can the Solow model not compare the welfare of different steady states as effectively as the RCK model?
2. What does the RCK model endogenize by incorporating household preferences and incentives?
3. An economy has population growth at rate , while each household member continues to supply one unit of labor. What happens to total labor supply over time?
Why can't the Solow model compare welfare between steady states?
Because its saving rate is exogenous.
What does the Ramsey-Cass-Koopmans model endogenize?
Saving by allowing individuals to choose consumption and saving based on preferences and incentives.
What is the population growth rate symbol in the model?

How does population growth affect the effective discount rate?
It changes the discount rate from to .
