Question 2Assume production function is given by:Y= K(1/2) L(1/2)a. Write the production function in per worker terms (y=f(k))b. Assume that the per worker level of capital in the steady state is 4, the depreciation rate is 5% per year, and population growth is 5% per year. Does this economy have “too much” or “too little” capital? How do you know? [Show your work].
W (2 bookr Suppose that the depreciation rate increases. In the Solow growth model, determine the effects of this on the quantity of capital per worker and on output per worker in the steady state. Explain the economic intuition behind your results.
Consider the Solow model with a production function Y(t) = A*K(t)αL(t)1-α, Where A is a fixed technological parameter. Explicitly solve for the steady-state value of the per capita capital stock and per capita income. How do these values change in response to a rise in (a) the technological parameter A, (b) the rate of saving s, (c) α , (d) δ, the depreciation rate, and the population growth rate n?

Consider the Solow-Swan model of growth. Imagine that the production function is Y = AKªL²-a 1. Use the production function to compute output per capita, y = Y /L, as a function of capital per person, k = K/L. 2. Derive the fundamental equation of the Solow-Swan model. Please show all the steps. Furthermore, imagine that the savings, depreciation, and population growth rates take the values s = 0.3, 8= 0.1 and n =0.01. You do not know the value of A. 3. Use the fundamental equation of the Solow-Swan model to compute the growth rate of capital per person as a function of k. 4. In the steady-state, the growth rate of capital is zero.

Imagine that this country is in its steady state so its capital stock is k_. Imagine that the country receives a gift of one unit of capital from the world bank (so, suddenly, the capital stock is k_+1). Can you say…
Consider our graph of the basic Solow growth model. On the graph above: y represents real output (or income) per worker; y=F(k) is the production function; k is the capital stock per worker; s is the savings rate; δ is the rate of depreciation of capital; ‘i’ represents business investment (purchases of capital) per worker); ‘LF’ stands for Loanable Funds. (For purposed of intuition, think of capital as ‘machines.’) If we started out with a capital (per worker) stock lower than the steady-state stock ( , above), we would expect to see which of the following happen over time? Group of answer choices A) Positive growth rates while the capital stock increases. B) Negative growth rates while the capital stock increases. C) Negative growth rates while the capital stock decreases. D) Positive growth rates while the capital stock stays less than the steady-state level. E) Positive growth rates while the capital stock decreases.
Consider a Solow-Swan model with saving rate s - 0.4, labour force growth g, - 0.05. constant productivity A = 1, and depreciation = 0.05. If output per worker is y = Y/L = 200 and capital per worker is k = K/L = 800, which of the following is true? O Efective depreciation per worker is 60, saving per worker is 80 and k will decrease towards the steady state Effective depreciation per worker is 80, saving per worker is 80 and k is at the steady state O Efective depreciation per worker is 60, saving per worker is 80 and k will increase towards the steady state O Effective depreciation per worker is 80, saving per worker is 60 and k will decrease towards the steady state
A key assumption of the Solow Growth Model is that: (a) the marginal product of capital diminishes as additional units of capital are added; (b) output per capita declines as a nation’s capital to labor ratio increases; (c) the marginal product of labor tends to rise as additional units of labor are added; (d) capital tends to depreciate at an increasing rate as a nation’s output increases.
. This part considers a modified version of the Solow growth model. Suppose the production function is given by F(K,bN) = K°(bN)1-a where b is the labour augmenting technology, which grows at a rate f, i.e., b+1 = (1+ f)b. For simplicity, assume that the total factor productivity z = 1, and the population is constant, i.e., N, = N for all t. The rest of the model is the same as in the standard Solow model in the textbook. Especially, the aggregate capital stock evolves according to Kt+1 = I4 + (1 – d)Kt. And assume that the economy is still closed, and there is no government. For any aggregate variable X, let the lower case letter a be the variable per effective unit of worker; that is a = *. Show that the production technology specified above satisfies the assumption of con- stant returns to scale.
