Consider the following hypothetical economy. The production function is Cobb-Douglas and labor's share of income is 70%. All values are continuously compounded, annualized growth rates, in percent. Growth in real wages: 2.0

Growth in capital stock: 4.0

Growth in real rental rate of capital: 1.0

a. Using the information provided in the table above, your best estimate of growth in TFP is A. 1.4% B. 2.9% C. Not enough information to answer D. None of the above

b. Consider a small open economy. If national savings is 90, the trade surplus is 5 and the country's investment curve is described by i(r) = 110 * 500 r, then the world interest rate must be A. 5% B. 2% C. 1% D. Cannot tell

Expert Solution

Part a) correct answer is (c) Not enough information to answer

to estimate growth in TFP (total factor productivity), we require growth in labor, growth in capital, growth in ouput, share of labor in output and share of capital in output. Out of these variables, we donot have growth in output and growth in labor

Total factor productivity captures anything that changes the relation between measured inputs and measured output.

Part b) correct answer is (a) 5%

world interest rate is 5%

Consider the following Cobb Douglas production function: Y= K2/5L3/5. The rate of depreciation in the economy is 2% and the marginal propensity to save (mps) is 30%. Any output that is not saved is consumed and this is a closed economy. Population growth rate is zero. 1. Continue with the same data with the exception that mps is unknown. Solve for the rate of investment which will ensure golden rule of consumption per capita 2. Continue with the same data...

Consider the Cobb-Douglas production function ?=??^??^??^? where ?, ?, ?, ? are positive constants and ?+?+?<1. Let ? be the amount of labor, ? the amount of capital, and ? be the amount of other materials used. Let the profit function be defined by ?=?−(??+??+??) where the costs of labor, capital, and other materials are, respectively, ?, ?, and ?. Determine whether second order conditions for profit maximization hold, when the profit function is defined by ?=?−(30?+20?+10?) with ?=5?^0.3?^0.4?^0.2.
