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?

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 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.
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%
An increase in research productivity: Suppose the economy is on a balanced growth path in the Romer model, and then, in the year 2030, research pro-ductivity z rises immediately and permanently to the new level z r. (a) Solve for the new growth rate of knowledge and yt.(b) Make a graph of yt over time using a ratio scale.
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 you add a variable rate of population growth to a two-sector model of growth. Draw and properly label a graph on how the production function, investment requirement line, and saving line look like. Does the addition of the variable rate of population growth to this model help you explain anything that a simpler two-sector model with a fixed rate of growth, or a one sector model with variable population growth, cannot? Expound.
Consider the Ramsey growth model with utility function Assume there are no taxes. a. Derive the conditions describing a steady state. b. Solve these conditions to obtain the steady-state values of C, K, and L. c. What is the effect on the steady state of an increase in b?
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.
As economic growth models become more and more inclusive of realistic conditions and incorporating complexities of the economy, disaggregation on inputs were introduced in capital (having physical and financial components). How does this labor disaggregation compare with that of capital, and its implications with less developed countries like the Philippines (aiming for a more robust economic growth)?
Consider an economy with a Cobb-Douglas production function with α = 1/3 that begins in steady state with a growth rate of technological progress of g of 2 percent. Consider what happens when g increases to 3 percent. (a) What is the growth rate of output per worker before the change? What happens to this growth rate in the long run? (b) Perform a growth accounting exercise for the economy, decomposing the growth rate in output per capita into components contributed by capital per capita growth and technology growth. What is the contribution of the change in g to output per capita growth according to this formula? (c) In what sense is the growth accounting result in part b producing a misleading picture of this experiment? Explain why this is the case.
How does a fall in the growth rate of technology (g) affect equilibrium capital and consumption in the Ramsey model
an economy is given by y=k^( 1/3). The depreciation rate is 16%, the saving rate is 26%, the growth rate of the labor force is 4%, and the growth rate of labor-augmenting technological change is 4%. Given these features, this economy's steady-state level of capital per effective worker is (Enter your response rounded to two decimal places.)
