Q1) Consider a Solow economy that is on its balanced growth path. Assume for simplicity that there is no technological progress. Now suppose that the rate of population growth falls.
(a) What happens to the balanced-growth-path values of capital per worker, output per worker, and consumption per worker? Sketch the paths of these variables as the economy moves to its new balanced growth path.
(b) Describe the effect of the fall in population growth on the path of output (that is, total output, not output per worker).

- (III) Consider a version of the Solow growth model without technological change covered in lecture with a rate of population growth of zero (i.e. n=0). Assume that the country has been at the BGP for many years and that suddenly at time t ̅ there is a onetime increase in its population. Show how the economy will adjust to a new BGP by working with the modified system (per capita/worker variables). Show how capital per worker adjusts to the new Steady State level and how its growth rate changes over time.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).We presented two versions of the Solow growth model. (1) In the simple version, there is no technological progress. Show in this simple version that at the steady state output per worker (GDP per worker) depends positively on the saving rate, and negatively on the population growth rate. What’s the growth rate of GDP at the steady state? What’s the growth rate of GDP per worker at the steady state? (2) In the version of the model with technological progress, what’s the growth rate of GDP at the steady state? What’s the growth rate of capital per worker at the steady state? What’s the growth rate of GDP per worker at the steady state? Show your steps
- An economy described by the Solow growth model has the following production function: y = Vk A. Solve for the steady-state value of y as a function of s, n, g, and d. B. A developed country has a saving rate of 28 percent and a population growth rate of 1 percent per year. A less developed country has a saving rate of 10 percent and a population growth rate of 4 percent per year. In both countries, 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?Derive the equilibrium law of motion for capital per worker in the Solow growth model (equation 7-19). State which equation you start with, and the operation you perform at each step. 2. Graph this equation in the space of capital tomorrow on the y-axis and capital today on the x-axis, and explain how you identify the steady-state level of capital per capita from the graphThe validity and ability of the Solow Growth Model in explaining the long-term growth of a country has been tested empirically.(a) In the Solow Growth Model we are introduced to the concept of the Golden Rule; optimum level of saving and capital formation to support growth. Is this Golden Rule concept proven empirically?(b) From what we have learned from the Solow Growth Model, describe some policies that can improve a country's economic growth rate.
- Production function is given by Y = 3K"(AN)!-a, where a=2/3. The rate of depreciation of capital is equal to 12 percent, the rate of technological progress is equal to 5 percent, and the rate of population growth is equal to 3 percent. The economy was in the steady state at time t and the level of technology was equal to A:=30. Use the Solow growth model to answer the following questions. (Please fill in numbers; use a comma as a decimal separator: 10,5) 1. If the saving rate s=40 percent, the steady state level of output per unit of effective labor at time t is equal to 2. If the saving rate s=40 percent, the steady state level of consumption per unit of effective labor at time t is equal to 3. If the saving rate s=40 percent, the steady state level of consumption per worker at time t is equal toSuppose an economy described by the Solow model is in steady state with population growth n of 1.8 percent per year and technological progress g of 1.8 percent per year. total output and total capital grow at 3.6 percent per year. suppose further that the capital share of output is 1/3. if you used the growth accounting equation to divide output growth into three sources- capital, labor, and total factor productivity- how much would you attribute to each source? compare your results to the figures we found for the united states in tables 9-2.Use the Solow model with exogenous growth to answer the following.Q 3.1: Following a reduction in the population growth rate, output per worker growth permanently increases. True or False Q 3.2: Following a reduction in the population growth rate, output per worker growth permanently increases. True or False Q 3.3: The only way to increase the long-run growth rate of output per worker is to increase the growth rate of labor efficiency. True or False Q 3.4: Following a decrease in TFP, output per worker growth temporarily declines. True or False
- The Solow Growth Model is an exogenous model of economic growth that analyzes changes in the level of output in an economy over time as a result of changes in the population growth rate, the savings rate, and the rate of technological progress. Consider the Solow model. a) Explain using a graph why there is a poverty trap in this model b)Describe how an economy such as one characterized by this model may break out of a poverty trap.Assume that an economy is described by the Solow model in the long run. The rate of population growth in this economy isn=0.01 and the rate of technological growth is g= 0.02. What are the long-run (steady state) growth rates of total GDP, GDP per worker, and GDP per effective worker?Production function is given by Y= (1/2)K^a(AN)^(1-a), where a=2/3. The rate of depreciation of capital is equal to 15 percent, the rate of technological progress is equal to 3 percent, and the rate of population growth is equal to 2 percent. The economy was in the steady state at time tand the level of technology was equal to A=80. Use the Solow growth model to answer the following questions. 1. If the saving rate s=80 percent, the steady state level of output per unit of effective labor at time tis equal to ... 2. If the saving rate s=80 percent, the steady state level of consumption per unit of effective labor at time tis equal to ... 3.
