Question 1: Factor Accumulation, Productive Efficiency and Savings Consider two countries: Country A and Country B. Country A's real per capita GDP growth rate (percent change in output) has been much higher than that in Country B during the last few decades. Also, Country A's real GDP growth (not in per capita terms) has been higher than that in Country B during this period. Country B currently has higher living standards than Country A. a) Using the Solow growth model (with no technological progress or population growth), is there a reason to believe this disparity in per capita growth rates will disappear over time? Show on your diagram and explain. b) How would your conclusion to part a) change if Country A had a higher saving rate than Country B? C) Suppose that Country A and B had the same savings rate, but Country A had a higher population growth rate. Could this explain the disparity in real per capita GDP growth rates? What about the disparity in real GDP growth (not in per capita terms)? Show and explain using the formulas for growth rates in the Solow growth model. d) How would your conclusion from part a) change if you considered technological progress in the Solow growth model, where the rate of technological progress is higher in Country A? e) How would your conclusion from part a) change if you considered an endogenous growth model, using the production function Y = AK
