Consider an economy that has access to a production technology Y = AKαL1−α 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 δ = 0). The x˙ population growth rate is n. (Throughout, gx = x , where x can be any of the variables in the model.) (a) Assume that technology is determined by A = BKφ What sort of endogenous growth model is this? Find K/K in terms of the K, L, and other parameters of the model.
Consider the simple innovation model. In this model, the society allocates a fraction "gamma" of workforce to innovation and the remaining fraction to production. Suppose that, for simplicity, total workforce is normalized to unity: L = 1. If the productivity growth rate is defined by d A_t / d t = "theta" * "gamma" * A_t and real GDP per worker by y_t = A_t * ( 1 - "gamma" ), what is the long-run growth rate of y_t ?
Consider the simple innovation model studied in class. In this model, the society allocates a fraction "gamma" of workforce to innovation and the remaining fraction to production. Suppose that, for simplicity, total workforce is normalized to unity: L = 1. If the productivity growth rate is defined by d A t/dt = "theta"* "gamma" * A_t and real GDP per worker by yt = At* (1 - "gamma"), what is the long-run growth rate of y_t?
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.
Suppose that , z the marginal product of efficiency units of labor, increases in the endogenous growth model. What effects does this have on the rates of growth and the levels of human capital, consumption, and output? Explain your results.

Suppose the economy is on a balanced growth path in the Romer model, and then, in the year 2030, ̄l (lower case L bar) decreasesimmediately and permanently to the new level ̄l′ (lower case L bar one). (a) Solve for the new growth rate of knowledge and yt. (b) Make a graph of yt over time using a ratio scale.
Draw a well labeled graph that illustrates the steady state of the solow model with population growth. Use the graph to find what happens to steady state capital per worker and income per worker in response to each of the following exogenous changes D. A one time permanent improvement in technology increases the amount of output that can be produced from any given amount of capital and labor. Note:- Do not provide handwritten solution.

answer all! Consider the Endogenous Growth Model with the representative consumer. The efficiency parameter of human capital accumulation technology is b = 5. The total productivity factor is given by z = 60. Denote by Ht the human capital accumulated in period t, and by ut the time spent working in period t. Assume u0 = 0.85 and H0 = 1. 1. Compute the consumer consumption Ct for periods 0 and 1. 2. Starting from year 2, the government applies a policy that raises b to 9. Now assume that in face of this increased value of human capital in the economy, the consumer responds optimally by decreasing ut to 0.75. Calculate the consumption Ct for periods 2 and 3.
Sweden and Norway are two neighboring countries in Northern Europe with similar savings rates, population growth rates, technology growth rates, and depreciation rates. However, Norway differs from Sweden in that Norway has large deposits of oil all along its coast, which makes it very easy for Norway to produce large quantities of crude oil every year with relatively little capital and labor. a) Draw a Solow Growth diagram that compares Sweden and Norway. What is the main difference between the two countries in the diagram? b) According to the Solow Growth Model, which country would have a higher standard of living in the long run? Which country would have a higher growth rate of its standard of living in the long run? c) Suppose now that, in the long run, oil becomes obsolete and has no value because it is uneconomical relative to renewable energy sources like solar and wind power. What would this do to your Solow Growth diagram in part a? How would the standard of living in Norway…
Assume that the growth rate of the capital stock in each period is determined by the level of output in the previous period. 1) An economy of 80 million people has ten percent of them engaged in research and development, where their productivity is 0.0035. The economy is on a balanced growth path, when suddenly 2.88 million people move from goods production into R&D, raising the fraction there to 13.6 percent. In the one period that begins with this labor reallocation, the growth rate of output is ________. [Refer to the instruction above.] A) 2.8% B) 0.0% C) 3.8% D) 2.2%
In 1998, Brazil had a per capita GDP of about $4,500, compared to per capita GDP of about $28,000 in the US. (A) If per capita growth were to average 2% per year indefinitely in the US and 5% per year in Brazil, how many years would it take Brazil to catch up with the US? (B) Using the assumptions of the Cobb-Douglas production function, how fast would capital stock have to grow for per capita GDP to rise 5% per year? How does that compare with capital stock growth of 3% per year in the US (assume technology advances 1% per year in both countries)? (C) In mature industrialized societies, the capital/output ratio is approximately 3.0. If the average depreciation rate is 0.04, what would be the current saving and investment ratio in the US? What would it be in Brazil if per capita GDP rose 5% per year?
