capital intensity of the production process.
c.
a country’s production function.
d.
the health and educational level of the population.
5. Because of population growth, Ghana’s GNP must grow by 1.5 percent per year just to avoid a decline
in average standards of living. With an ICOR of 6.0, achieving this minimum-growth target requires a
saving rate of:
a.
18 percent.
c.
50 percent.
b.
3 percent.
d.
9 percent.
6. Suppose the saving rate for a low-income country is given. If production becomes less capital
intensive, the ICOR will ________ and the growth rate will _________.
a.
increase; increase
c.
decrease; decrease
b.
decrease; increase
d.
increase; decrease
7. Consider the Harrod-Domar relationship for an economy:
g = (s/v) – d
Assume that the depreciation rate is 0. If the saving rate is 24 percent, the ICOR is 3, and the
depreciation rate is 5 percent, the economy can be expected to grow:
a.
8 percent.
c.
3 percent.
b.
19 percent.
d.
2 percent.
8. Consider the Harrod-Domar relationship for an economy:
g = (s/v) – d
Assume that the depreciation rate is 0. A country can only save 15 percent but wants to grow 15
percent. Assuming the ICOR is 3, the gap of ________ should be provided by foreign aid.
a.
10 percent
c.
5 percent
b.
0 percent
d.
We cannot say without more information.
9. If the investment rate in Indonesia is 29 percent of GDP, which of the following combinations is
consistent with the Harrod-Domar growth model?
a.
ICOR = 15.4; GDP growth rate = 7.6 percent per annum
b.
ICOR = 2.86; GDP growth rate = 5.1 percent per annum
c.
ICOR = 50.6; GDP growth rate = 2.2 percent per annum
d.
ICOR = 1 percent; GDP growth rate = 22 percent per annum
10. According to the Harrod-Domar model, what effect does an increase in the saving rate have on
long-term growth?
a.
leads to an increase
b.
leads to a decrease
c.
the advent of hyperinflation
d.
difficult to determine because of the unknown level of corruption in government
11. One of the problems of the Harrod-Domar framework is that its fixed-proportion production function
does not allow for any:
a.
population growth.
c.
endogenous technical change.
b.
substitution between labor and capital.
d.
depreciation.
12. From 1999–2007, Thailand’s economy experienced an annual growth rate of:
a.
2.1 percent.
c.
4.7 percent.
b.
3.9 percent.
d.
7.5 percent.
13. Unlike isoquants for a fixed-coefficient production function, the isoquants for a neoclassical
production function:
a.
take labor as well as capital into account.
b.
are L-shaped.
c.
are capital-intensive rather than labor-intensive.
d.
are curved.
14. According to the Solow model, the relationship between saving and growth is not linear because of:
a.
coordination failures between the banking sector and industry.
b.
business cycles that naturally occur in all economies.
c.
diminishing returns to capital in the production function.
d.
fluctuations in macroeconomic policy.
15. When an economy increases the amount of capital per worker, it is called:
a.
capital widening.
c.
labor widening.
b.
capital deepening.
d.
labor deepening.
16. In the Solow model, an increase in the population growth rate leads to:
a.
capital deepening.
b.
dynamic economic growth and development.
c.
the fulfillment of the Malthusian hypothesis.
d.
lower average income per worker.
17. The most unsettling conclusion of the Solow model is the conclusion that once the economy reaches
its long-run potential level of income, economic growth simply:
a.
declines, leading to what is referred to as a “failed state.”
b.
matches population growth, with no chance for sustained increases in average income.
c.
causes a rapid inflation, leading to an erosion of gains made during the growth period.
d.
subsides, as socialism becomes an acceptable form of political economy for the people.
18. While there is no evidence of absolute convergence, there is strong evidence today of conditional
convergence in which:
a.
countries sharing certain characteristics are able to achieve rapid growth and begin to
catch up with the richer countries.
b.
by entering into the World Trade Organization, a nation implicitly and explicitly agrees to
integrate into the global economy.
