Chapter 9, Problem 1QQ
To determine
The output per person.
Expert Solution & Answer
Answer to Problem 1QQ
Option (c) is the correct answer.
Explanation of Solution
Option (c):
When the rate of population growth is 1 percent, the rate of technological progress is 3 percent, the
Option (a):
When the rate of population growth is 1 percent, the rate of technological progress is 3 percent, the depreciation is 5 percent and the saving rate is 10 percent, the output per person will not grow at 1 percent. Thus, option (a) is incorrect.
Option (b ):
When the rate of population growth is 1 percent, the rate of technological progress is 3 percent, the depreciation is 5 percent and the saving rate is 10 percent, the output per person will not grow at 2 percent. Thus, option (b) is incorrect.
Option (d):
When the rate of population growth is 1 percent, the rate of technological progress is 3 percent, the depreciation is 5 percent and the saving rate is 10 percent, the output per person will not grow at 4 percent. Thus option (d) is incorrect.

Suppose the Solow model describes an economy. The population grows at a 0.5% rate, and its labour efficiency grows at a 1% rate. Thus, in the steady state, capital per worker grows at a ____ rate.
a.
1.5%
b.
0%
c.
0.5%
d.
1%
Q.2An economy described by the Solow growth model has the following production function:
y = Vk.
a.Solve for the steady-state value of y as a function of s, n, g, and d
b. A developed country has a saving rate of 28 percent and a population growth rate of 1 percent per year. A less
developed country has a saving rate of 10 percent and a population growth rate of 4 percent per year. In both
countries, g = 0.02 and d = 0.04. Find the steady-state value of y for each country.
c. What policies might the less developed country pursue to raise its level of income?

- In the Solow–Swan model, a decrease in the rate of population growth will have what effect on the steady-state level of real GDP per capita? a. Increase b. No change in real GDP per capita because although it does change the rate at which output and population are growing, it will make both growth rates change by the same amount and so the output-population ratio will be unchanged c. Decrease d. No change in real GDP per capita because although it does change the level of labour, the level of capital will change to keep the capital-labour ratio the same as beforearrow_forwardAssume that an economy is described by the Solow model in the long run.

The Solow model says that population growth will not benefit a country in the long run but Michael Kremer disagrees. Explain both positions. Use a graph to explain Solow's argument. 5. The amount of education the typical person receives varies substantially among countries. Suppose you were to compare a country with a highly educated labor force and a country with a less educated labor force. Assume that education affects only the level of the efficiency of labor. Also assume that the countries are otherwise the same: They have the same saving rate, the same depreciation rate, the same population growth rate, and the same rate of technological progress. Both countries are described by the Solow model and are in their steady states. How would the following variables differ between the countries? A. The rate of growth of total income B. The level of income per worker C. The real rental price of capital D. The real wagearrow_forward3.
