Question 3 : Solow model with long-run TFP growth [20 marks] Suppose output is given by Y = K}(AN) As in the basic model, the workforce grows at rate n, capital depreciates at rate d and the savings rate is s. In addition, suppose that TFP grows at a constant rate g. That is: ΔΑ A9 We will refer to the product AN as the "effective workforce". It follows that the effective workforce grows at rate n+g. a. Express the...

Consider the Solow growth model with the following production function where y is output. K is capital, s is the productivity and is labor. Assume that 0 < α < 1 Further, suppose that labor grows at a constant rate n. That is. 1 + n. Also, assume that capital depreciates at rate d and that gross investment in capital is fraction s of output. a Letting k-N, obtain the law of motion for capital accumulation...
Suppose we introduce government purchases into the Solow Growth
model. The production technology
is given by
1. Suppose we introduce government purchases into the Solow Growth model. The production technology is given by Y = AK N- where A is some measure of total factor productivity, K, is the level of capital and N is the size of the labor force. Output is split between consumption, C, investment, I, and Government purchases, G. according to Y=C +I+G. Assume that government...
3 Growth Model Suppose that output (Y) in an economy is given by the following aggregate production function: Y = K + NE where Kt is capital and Nt is the population. Furthermore, assume that capital depreciates at rate 8 and that savings is a constant proportion s of income. You may assume that 8 > S. 1. Suppose that the population remains constant. Solve for the steady-state level of capital per worker. 2. Now suppose that the population grows...
11. In the Solow model the key driver of economic growth is a) accumulation of human capital b) accumulation of physical capital c) technological progress d) quality of institutions Kt+1-K The capital accumulation of physical capital is the key equation 12. Let AK+1 of the Solow model, which is the following a) Kt+1 +(1- d)K b) AK41= I+(1 - d)K c) Kt41 Ki-dK d)AK1I- K 13. According to the Solow diagram, no matter if the initial level of capital, Ko,...

14. One of the following is NOT a feature of the Solow Model a) long-term economic growth rate b) If an economy is far from its steady-state level, it grows faster, so the closer the economy is to the steady-state value the growth rate moves to zero c) capital accumulation cannot serve as the engine of long-run economic growth d) Eventually net investment - subtracting depreciation from investment is zero and the economy stabilizes at the steady state 15. Consider...
3) Consider the Solow model with population growth and labor-augmenting technological progress. Suppose that the aggregate production function is Cobb- Douglas, i.e. Y = AK"(E · L)1-a, where A is a constant, while E denotes technological progress and grows at rate g. Labor grows at an exogenous rate n, and capital depreciates at rate d. As usual, people consume a fraction (1 – s) of their income. a. Use a graph similar to what we have seen in class to...
