Hello can you please help with these questions.I have a test in a week

12. Which of the following variables would be most likely to display a positive correlation with levels of per-capita income in a cross-section of countries if the Solow Model is true? A.) The savings rate s. B.) The population growth rate n. C.) The depreciation rate 6. section of countries. D.) All of the variables above are likely to display a positive correlation with per-capita income in a cross E.) None of the variables above is likely to display a positive correlation with per-capita income in a cross section of countries. 13. Country A and Country B are identical with respect to several important variables. They share the same value of the capital share a, the same population growth rate n, the same depreciation rate o, and the same rate of technological progress g. Levels of technology E and population L are also the same in the two countries. The two countries have different savings rates, however; Country A's saving rate SA is higher than Country B's saving rate SB. Which country will have the higher growth rate of aggregate output Y in steady state? A.) Country A. B.) Country B. C.) Country A and B will share the same growth rate of aggregate output Y in steady state. 14. (Continuing the previous question.) Which country will have the higher growth rate of output-per-worker in steady state? A.) Country A. B.) Country B. C.) Country A and B will share the same growth rate of output-per-worker Y/L in steady state. 15. (Continuing the previous question.) Which country will have the higher marginal product of capital MPK in steady state? (Note: This question is asking about the level of MPK, not the growth rate of MPK.) A.) Country A. B.) Country B. C.) Country A and B will share the same level of MPK in steady state
