8. Reinterpret the endogenous growth model in this chapter as follows. Suppose that there are two groups of people in a country, the low- skilled workers and the high-skilled workers. The low-skilled workers have less human cap- ital per person initially than do the high-skilled workers. In the economy as a whole, output is produced using efficiency units of labor, and total factor productivity is z, just as in the endogenous growth model in this chapter. Each individual in this economy accumulates human capital on their own, and each has one unit of time to split between human capital accu- mulation and work. However, now b = bn for the high-skilled, b un for the high-skilled, and u the low-skilled. In the United States, there has been an increase in the gap between the wages of high-skilled workers and low-skilled work- ers, that has occurred over the last 30 years or bị for the low-skilled, for so. Determine how this model can explain this observation, and discuss.

1. Many endogenous growth models feature so called scale effects: per capita growth rises when population growth rises. Some economists have criticized these models for this reason, since countries with faster population growth do not in general appear to also experience faster per capita income growth. Consider an economy that has access to a production technology Y = AKª L¹-a where Y is output, A is the level of technology, K is capital and L is the amount of labor in the economy. Capital evolves according to K = SY (thus, the depreciation rate 6 = 0). The population growth rate is n. (Throughout, gx, where x can be any of the variables in the model). i. Assume that technology is determined by A =BK What sort of endogenous growth model is this? Find gk in terms of the K, L, and other parameters of the model. ii. Write an expression for gy in terms of gk and g₁. What must be true for a balanced growth path to exist in this model? Solve for the balanced growth path value of gy and gy,…

Based on our discussion of the determinants of economic growth, answer the following questions: • ’Devoting a larger share of national output to investment would help restore rapid economic growth and rising living standards.’ Based on our discussion of the determinants of economic growth, do you agree with the above statement? Explain why. • What could the policymakers (i.e., government, central bank) do to increase the investments in the economy? • Do you think that increasing the saving rate could help to increase the economic growth? Explain why. • Do you think that increasing the saving rate is always helpful? I.e., could we increase the saving rate to, say, 90 %? What could be some of the drawbacks of increasing the saving rate to a very high level? Explain.
6.5 Exercises Exercise 6.1 (Technological Progress and Long-Run Growth). Consider a Solow economy with population growth and technological progress. The evolution of the capital stock per efficiency unit of labor, denoted k1, is given by the law of motion (1+n)(1+ g)kt+1 = (1 – 8)kt +of(kt). Capital per efficiency unit of labor is defined as k, = Kt/(LEt), where Kt denotes the stock of physical capital, L, denotes population, and E is a tech- nological factor. Population grows at the rate n and the technological factor grows at the rate g. The subscript t denotes time, measured in years. The parameters d E (0, 1) and o > 0 denote, respectively, the depreciation rate of capital and the savings rate. The function f(k;) represents the produc- tion technology. Specifically, let Y, denote output and yt = Yt/(LEt) denote output per efficiency unit of labor. Then yt = f(kt). Assume that f(kt) = /k. 1. Find the steady-state stock of capital per efficiency unit of labor, de- noted k*, as a…

“Since 1980, aggregate per capita GDP in sub-Saharan Africa has declined at almost 1 percent per annum. The decline has been widespread: 32 countries are poorer now than in 1980. Today, sub-Saharan Africa is the lowest-income region in the world...It is clear that Africa has suffered a chronic failure of economic growth. The problem for analysis is to determine the causes” (Collier and Gunning 1999: ‘Why has Africa grown slowly?’). Explain the possible reasons why sub-Saharan Africa grew so slowly from 1980- 1999?
Suppose, a country X has a GDP level of 4, 50,000 and a growth rate of 10% in 2007(calculated at the end of the fiscal year 2007). The experts predict that the growth ofthe economy of Country X will gradually slowdown in the coming years. Moreprecisely, they foresee the following growth rates for the future:2007 – 2010 = 10%2010 – 2013 = 9%2013 – 2016 = 7.5%2016 – 2019 = 5%2019 – on = 1% Hint: The list above should be read as saying that, for instance, the growth rate fromthe end of the fiscal year 2007 until the end of 2010 will be 10 %, then from the end of2010 until the end of 2013 it will be 9% and so on. Assuming that the predictions of the experts listed above are accurate, when in thefuture will Country X’s GDP double compared to the GDP level of 2007? Consider now the more optimistic scenario in which the economy does not slow downand the current growth rate of 10% remains constant in the coming years. How longwill it take for the GDP level to double in this scenario? Express…
) The goal is to analyze further the two-sector endogenous growth model. Write down the equation of motion for k, which shows delta k as saving minus break-even investment. (Break-even investment is the amount of investment needed to keep capital per effective worker constant.) Draw a graph that determines the steady-state k. In this economy, what's the steady-state growth rate of output per work? How do the saving rate and fraction of labor force in universities (u) affect this steady-state growth rate?
