12. Discuss how population growth affects economic growth in the Solow growth model. Also discuss alternative points of view regarding population growth and how it contributes to or detracts from economic growth.
1. Draw a well-labeled graph that illustrates the steady-state of the Solow model with population growth. Use the graph to find what happens to steady-state capital per worker and income per worker in response to each of the following exogenous changes.a. A change in consumer preferences increases the saving rate.b. A change in weather patterns increases the depreciation rate.c. Better birth-control methods reduce the rate of population growth.
3. An economy described by the Augmented Solow growth model has the following production function with populationgrowth (1+n) and technological growth (1+z):y =p(k)(a) Solve for the steady-state values of capital per capita and output as a function of s, n, z, and δ.(b) A developed country has a saving rate of 28 percent and a population growth rate of 1 percent per year. A lessdeveloped country has a saving rate of 10 percent and a population growth rate of 4 percent per year. In bothcountries, 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? Graphically demonstrate howyour advised policy would increase income per capita (y).
1 According to the Solow Model, which of the following statements is correct? 1. An increase in the depreciation rate of capital reduces the long-run growth rate of per-capita output 2. An earthquake that destroys 20 percent of the country capital reduces the long-run level of output 3. An increase in the rate of population growth reduces the long-run growth rate of per-capita output 4. A permanent increase in the Total Factor productivity increases on the long-run level of per-capita output
Solo growth model questions 1.) a. In a Solow growth model that is expressed in per capita terms, what happens to the marginal product of capital as an economy's capital/labor ratio increases? b. In a Solow growth model that is expressed in per capita terms, when an economy is in its steady state, what do you expect to happen to the capital-labor ratio? c. In a Solow growth model that is expressed in per capita terms, what happens to the capital/labor ratio when the savings rate rises? d.In a Solow growth model that is expressed in per capita terms, what happens to the capital/labor ratio when economywide productivity (this is our "A" variable) rises?
6. Consider the Solow model discussed in class. Consider a population growth rate increase from n to n'. Show graphically what happens to capital per worker (k) and output per worker (y).
8.Consider the empirical evidence on the Solow growth model when the population growth rate, depreciation and savings rate is the same across countries and when technological progress has the same rate in all countries. a.The Solow growth model cannot be tested for a large set of countries because it requires knowledge of each country’s steady state. b.The Solow growth model is supported by unbiased data for a small sample of countries over a long period of time. c.The Solow growth model is supported because they catch up with technological investments d.The Solow growth model is not supported by a large sample of countries over a short period of time.
4. Suppose that the depreciation rate increases. In the Solow growth model, determine the effects of this on the quantity of capital per worker and on output per worker in the steady state. Explain the economic intuition behind your results.
9. Consider our graph of the basic Solow growth model. steady state dk y=F(() F() (-7' in LF equilibrium) On the graph above: y represents real output (or income) per worker; y-F(k) is the production function; is the capital stock per worker; s is the savings rate; 8 is the rate of depreciation of capital; 'i' represents business investment (purchases of capital) per worker); 'LF' stands for Loanable Funds. (For purposed of intuition, think of capital as 'machines.) If we started out with a capital (per worker) stock higher than the steady-state stock (above), we would expect to see which of the following happen over time? Positive growth rates while the capital stock increases. Positive growth rates while the capital stock stays less than the steady-state level. Negative growth rates while the capital stock increases. Positive growth rates while the capital stock decreases. Negative growth rates while the capital stock decreases.
12. According to Solow's model of economic growth, what determines the growth rate of income per person for a nation that is not in its steady state? What determines the growth rate of income per person for a nation that is in its steady state? In what sense is technological progress necessary for sustained growth of income per person in Solow's model?
15 True or False? The basic version of the Solow model (no population growth, no technological progress) implies an economy where growth is not Explain your answer.
Consider an economy as per solow model, with a Cobb-Douglas production function with constant returns to scale with respect to K and L. Moreover, you know that the economy is producing 80 units of total output and the productivity parameter is equal to 1. If the depreciation rate is 10%, the investment rate is 10%, and there are 75 workers, the growth rate of GDP per person ____________. a) is equal to zero because the economy is at its steady state b) is negative because the economy is above its steady state c) is positive because the economy is below its steady state d)cannot be determined
