physical capital has steadily increased, while human capital first increased and then
decreased. C) human capital has increased significantly, but not physical capital. D) physical and human capital have both increased significantly. E)

Assume that technological progress does not occur. In Japan, the rate of saving has generally been
greater than in the U.S. Given this information, we know that in the long run: 6) A) The U.S. growth rate will be greater than the Japanese growth rate. B) Output per worker in Japan will be greater than U.S. output per worker. C) Output per worker in the U.S. will be greater than Japanese output per worker. D) Japan’s growth rate will be greater than the U.S. growth rate. E) Capital per worker in Japan will be no different than U.S. capital per worker. Answer: B
Explanation: A) B) C) D) E) 2
7)
Suppose a recent budgetary policy results in an increase in the national saving rate. Such a change
in the saving rate will not affect which of the following variables in the long run? 7) A) The rate of growth of capital per worker. B) The level of output. C) The level of investment. D) Capital per worker. E) Output per worker. Answer: A
Explanation: A) B) C) D) E) 8)
Suppose the economy is initially in the steady state. A decrease in the depreciation rate (Έ) will
cause: 8) A) a decrease in Y/N.
B) a decrease in C/N.
C) an increase in K/N.
D) an increase in the growth rate in the long run. E) a decrease in the saving rate. Answer: C
Explanation: A) B) C) D) E) 9) Which of the following will likely cause an increase in output per worker? 9) A) An increase in education expenditures. B) An increase in on-the-job training. C) An increase in capital accumulation. D) An increase in the saving rate. E) All of the above. Answer: E
Explanation: A) B) C) D) E) 3
10)
Assume zero population growth and zero technical change. If an outbreak of war destroys a large
portion of a country’s capital stock but the saving rate and the rate of depreciation are unchanged,
the growth model predicts that output will: 10) A) cease to grow. B) grow but the new steady state will be at a higher output level than before. C) grow but the new steady state will be at a lower output level than before. D) decrease to a new steady state. E) grow and the new steady state will be at the same output level as before. Answer: E
