4. Suppose two countries have identical constant-returns-to-scale production functions and start with the same capital stock per effective worker (). Both countries have a population growth rate of 1%, rate of k technological progress of 3%, and a depreciation rate of 10%. However, the savings rate differs in each country. Country Sunny saves 15% of its income, while Country Rainy saves 30%. Assume that the initial capital stock per effective worker () lies below each country's respective steady state level. Which country will exhibit faster changes in capital per effective worker (A ) in the first couple periods? Explain and illustrate your answer on a Solow graph. All curves/axes are expressed in terms of per effective worker and

Assume that a country's per-worker production is y = k1/2, where y is output per worker and kis capital per worker. Assume also that 10 percent of capital depreciates per year (= 0.10) 2 andthere is no population growth or technological change.a. If the saving rate (s) is 0.4, what are capital per worker, production per worker, andconsumption per worker in the steady state?b. Solve for steady-state capital per worker, production per worker, and consumption perworker with s = 0.6.c. Solve for steady-state capital per worker, production per worker, and consumption perworker with s = 0.8.d. Is it possible to save too much? Why?

3 pts in the Solow model, the economy reaches a steady-state because as capital per worker increases O savings per worker is constant, while the population growth rate is contare and the depreciation rate of capital decen, ing that the economy w gro endogenously while the population growth rate and the depreciation rate of capital are comitant implying that the economy will converge to a sady O marginal savings per worker diminishes, while the population growth rate and the depreciation rate of capital are constant implying that the economy will gro endogenously Osaving perv state. O marginal savings per worker diminishes, while the population growth rate and the depreciation rate of capital are constant, implying that the economy will converge to a steady-state

5. Suppose that the Country of Eldesarrollo has a gross savings rate of 25%, a depreciation rate of 3%, an incremental capital-output ratio of 2.75, a population growth rate of 1.5% per year, and a per capita income of $1500. a. Using the Harrod-Domar (or AK) growth model, calculate the implied rate of growth of total GNI in Eldesarrollo. b. What is the implied rate of growth of GNI per capita? c. How much would the rate of gross savings have to increase to raise the growth rate of total GNI to 9%? d. Suppose that one-quarter of all investment is completely wasted in Eldesarrollo. Returning to the original numbers, what is the resulting effective ICOR, and what is the corresponding new implied growth rate of total GNI?

The following table shows the GDP per capita of various countries forthe years 1960 and 2010 in PPP-adjusted 2005 dollars. The table alsocontains the implied growth rates, which show how much on average eachcountry needed to grow each year to reach the 2010 level of GDP per capitastarting from the 1960 level of GDP per capita. Use the table to answer thefollowing questions. 1. During 1960-2010, which countries were able to reduce the gap betweentheir GDP per capita and the U.S. GDP per capita?

4. Assume an endogenous growth model with a production function that in per capita terms can be written as y = 0.8k. If the savings rate is s = 0.3, the rate of growth of population is n = 0.03, and the rate of depreciation is d = 0.1, how high is the rate of growth of output per capita? %3D A. 14% B. 17% C. 13% D. 11% E. There is not enough information to calculate it.

5. Consider the Solow growth model. The production function is: Y = Kª(AN)!-«, the is the capital depreciation rate is & per year, the population and technology savıng rate grow at annual rates of n and g respectively. Calculate K/N, K/(AN), Y /N and Y/(AN) in the steady state. Does the change in s affect the growth rate? Explain. S, 6. Suppose that the model of the economy is given by Y = C +I+G + X 99 sunny hp 10 f8 144 14 is & 6. 7. 8. 24

Which impacts economic growth? O a decrease in the productivity of labor O an increase in the proportion of the population that is college educated O an increase in the average wage rate paid to workers O an increase in the standard of living

The below figure shows the investment rates (or saving rates) for Albania, Botswana, and Turkey from 1970 to 2014. Everything else equal, using the Solow model, which country would you anticipate to have the highest growth rate during the last 10 years? 70% 60% 50% 40% Mamy 30% 20% 10% 0% Albania -Botswana 1970 1973 O Albania O Botswana -----Turkey 1976 1979 1982 1985 1988 1991 1994 1997 2000 2003 2006 2009 2012 Turkey O Based on the Solow model, they should all have the same growth rate.
