- Suppose a Solow economy is initially at its steady state k∗, and suddenly is hit by a decrease in the depreciation rate δ, from δ to δ1. This change does not alter any of the other exogenous parameters in the model Depict this situation in a graph What happens to steady state level of capital per capita in this situation? What happens to the level of capital per capita over time? Depict this in a graph and explain intuitively.Q5 Suppose in a Solow model, we have the following parameter values: n = 0, s = 0.5, a = 0.3. There is no growth in the total factor productivity so that A, = A = 1. Moreover, we know that at time 0, the economy is at a steady state so that k = k, =1. Now imagine that a foreign power invaded this %3D country. 1% of the population was killed and another 14% of the population fleeded the country to avoid violence. Moreover, 15% of capital stocks were destroyed. All of this happens in period t=1. After that, the war ended and there was no more destruction of capital or loss of population (but the refugee permanently settled outside of the country and will never return0. What is the growth rate of per-capita output in period t =4?Consider the following numerical examples for the Solow Growth Model: Economy A z=1 s=0.5 F(K,N)=K0.3N0.7 n=0.01 d=0.1 Economy B z=1 s=0.2 F(K,N)=K0.3N0.7 n=0.01 d=0.1 In which economy is Consumption per capita higher in steady state?

O Economy A O Economy B O Not enough InformationAn increase in research productivity: Suppose the economy is on a balanced growth path in the Romer model, and then, in the year 2030, research productivity z̅ rises immediately and permanently to the new level z̅′. Solve for the new growth rate of knowledge and yt. Make a graph of yt over time using a ratio scale. Why might research productivity increase in an economy? I do not understand how to solve this, I'm confused. Am I supposed to make an equation or write out an answer?In class we assumed that the rate of population growth "n" was a constant. This was true for the Solow-Swan growth model as well as for the AK model. Imagine now that the rate of population growth is a function of k. Do you think fertility should be a function of k? An increasing or decreasing function of k? (Think of the costs and benefits of having children, and the reasons that lead people to purchase and produce kids) In the real world, do rich societies have larger or smaller fertility rates? Do you think mortality should be a function of k? An increasing or decreasing function of k? In the real world, do rich societies have larger or smaller mortality rates? Do you think net migration is a function of k? An increasing or decreasing function of k? In the real world, do rich societies tend to receive or to send migrants? а. b. C.
- = 2. Consider a Solow growth model in which the production function is Yt AK²N₁¹/2, where A = 1. Moreover, assume that the depreciation rate is d = 0.02, the rate of population growth is n = 0.02, and the saving rate is s = = 0.2. a. Compute the value of the capital stock per worker in steady state. b. Draw a graph that represents the steady-state equilibrium of the model. c. Suppose that the capital-labor ration in year t is 90. What will the level of the capital- labor ratio be in year t+1? Will it increase or decrease in future periods? Explain. d. Compute the rate of change of the capital labor ratio between time t and t + 1. How does it compare to the rate of growth of the capital-labor ratio in steady state?(a) Consider an economy that is initially in a steady state equilibrium. Assume that in this equilibrium it has a saving rate of 50 per cent and a depreciation rate of 2 per cent. Further assume that the population growth rate is 3% and that the level of output produced can be represented by the following production function: = where A = 1 and = 0.5. Use the Solow-Swan model to determine the level of capital per worker and output per worker in this economy. (1 mark) (b) Now suppose the government introduces a set of policies to improve the institutional set up as well as better production technique which increases total factor productivity by double. What is the new steady state level of capital per worker and output per worker? (1 mark) (c) Use a Solow-Swan diagram to show the qualitative effects of this new government policy upon steady state output per worker and capital per worker. Briefly describe the intuition behind this result. (1 mark) (d) Now suppose, population growth rate…The economic growth model(s) of ( ) below can be recognized as an endogenous model. A Slow-Swan model; B Ricardo’s model; C Romer-Lucas model; D Harrod-Domar model; E Aghiot-Howitt model.
- Production function is given by Y = Ka(AN)'¯ª, where a=2/3. Initially, the saving rate was equal to s and the economy was in the steady state. Use the Solow growth model to answer the following questions. (Please fill in numbers; use a yomma as a decimal separator: 10,5) 1. In order to increase capital per unit of effective labor in the steady state by a factor of 27 (i.e. to make it 27 times larger), the rate of saving needs to increase by a factor of 2. In order to increase output per unit of effective labor in the steady state by a factor of 4 (i.e. to make it 4 times larger), the rate of saving needs to increase by a factor of 3. Suppose that s=25 percent, the rate of depreciation of capital is equal to 5 percent, the rate of technological progress is equal to 1 percent, and the rate of population growth is equal to 0,25 percent, a=2/3. The steady state level of investment per unit of effective labor is equal toWhat is the main takeaway implication of the Malthusian growth model? In particular, what policy recommendation did Malthus derive from the set of mechanisms he thought was operating in the economy?Problem 2 In class we assumed that the rate of population growth "n" was a constant. This was true for the Solow-Swan growth model as well as for the AK model. Imagine now that the rate of population growth is a function of k. Do you think fertility should be a function of k? An increasing or decreasing function of k? (Think of the costs and benefits of having children, and the reasons that lead people to purchase and produce kids) In the real world, do rich а. societies have larger or smaller fertility rates? Do you think mortality should be a function of k? An increasing or decreasing function of k? In the real world, do rich b. societies have larger or smaller mortality rates? Do you think net migration is a function of k? An increasing or decreasing function of k? In the real world, do rich societies tend to receive or to send migrants? С. Imagine that n is a DECREASING function of k. Draw the savings and depreciation lines in the Solow-Swan models. d. In class we showed that, with…
