7. The natural rate of unemployment is:
A) the average rate of unemployment around which the economy fluctuates.
B) about 10 percent of the labor force. C) a rate that never changes.
D) the transition of individuals between employment and unemployment.
8. In the model of the steady-state unemployment rate with a fixed labor
force, the rate of job finding equals the percentage of the ______ who find a
job each month, while the rate of job separation equals the percentage of the
______ who lose their job each month.

rates are constant, then the unemployment rate is approximately:
A) f/(f + s). B) (f + s)/f. C) s/(s + f). D) (s + f)/s.
10. By paying efficiency wages, firms contribute to higher wait unemployment
because they:

C) keep the wage below the equilibrium level. D) keep the wage above the
equilibrium level.
11. The change in capital stock per worker (岛k) may be expressed as a
function of s—the saving ratio, f(k)—output per worker, k—capital per
worker, and 讦—the depreciation rate, by the equation:
A) 岛k = sf(k) / 讦k. C) 岛k = sf(k) + 讦k. B) 岛k = sf(k) 毕 讦k. D) 岛k
= sf(k) – 讦k.

A) divided by the depreciation rate. B) multiplied by the depreciation rate.
C) divided by the product of f(k*) and the depreciation rate. D) multiplied
by f(k*) divided by the depreciation rate.
13. If the per-worker production function is given by y = k1/2, the saving

of capital to labor is:
A) 1. B) 2. C) 4. D) 9.
14. The Solow model shows that a key determinant of the steady-state ratio of
capital to labor is the:

18. In a steady-state economy with a saving rate s, population growth n, and
labor-augmenting technological progress g, the formula for the steady-state
ratio of capital per effective worker (k*), in terms of output per effective
worker (f(k*)), is (denoting the depreciation rate by d):
A) sf(k)/(讦 + n + g). C) f(k)/((s)( 讦 + n + g)).
B) s/((f(k))( 讦 + n + g)). D) (s – f(k))/( 讦 + n + g).
19. If the per-worker production function is y = Ak, where A is a positive
constant, in the steady state, a:
A) lower saving rate does not affect the growth rate.
B) higher saving rate does not affect the growth rate.
C) lower saving rate leads to a higher growth rate.
D) higher saving rate leads to a higher growth rate.
20. When capital increases by 岛K units and labor increases by 岛L units,

問答題 (20分)
假設甲國之經濟具有如下 Solow growth model 之特性:
儲蓄率 (saving rate, s) .20
折舊率 (depreciation rate, δ) .12
長期穩定均衡平均每個工人資本(steady-state capital per worker, k) 4
人口成長率 (population growth rate, n) .02
長期穩定均衡平均每個工人產出(steady-state output per worker, y) 20,000
a. 長期穩定均衡平均每個工人資本之成長率是多少？(What is the steady-state
growth rate of output per worker?)
b. 長期穩定均衡平均每個工人產出之成長率是多少？ (What is the steady-state
growth rate of total output?)
c. 長期穩定均衡平均每個工人消費水準是多少？ (What is the level of
steady-state consumption per worker?)
d. 長期穩定均衡平均每個工人投資水準是多少？ (What is the steady-state level
of investment per worker?)
AACAD DADCD DDDCD BCADC
Ans:
Ans:
a. In the steady state, capital per worker is constant, so output per
worker is constant. Thus, the growth rate of steady-state output per worker
is 0.
b. In the steady state, population grows at 2 percent rate (.02). Capital
must grow at a rate of 2 percent in order to maintain a constant capital per
worker ratio in the steady state; therefore, given the constant returns to
scale production function, total output must increase at a 2 percent rate.
c. If the saving rate is 20 percent, then the consumption rate is 80 percent
(1 - .2). Steady-state consumption per worker is 16,000, which is 80 percent
of steady-state output per worker.
d. In the steady state, investment per worker equals saving per worker, which
is 20 percent of steady-state output per worker. Thus, steady-state
investment per worker is 4,000.
