An economy has the per-worker production function yt=f(kt)=4kt)0.4, where yt is the output per worker and kt is the capital-labor ratio. The depreciation rate is 0.15, and the population growth rate is 0.04. Saving is St=0.5Yt, where St is total national saving and Yt is total output. The slope of the per worker production function is given by f' (kt)=1.6kt-0.6 . What is the steady state value of capital-labor ratio, k*? Round your answer to at least 2 decimal places.

Assume the per-worker production function is y = k1/2, depreciation is 4 percent of %3D capital, the labor force grows at 2 percent, and the savings rate is 30 percent. Then, the steady-state equilibrium is achieved when capital per worker is equal to: 2.5. 5. 6.25. 25.

Using the production function Real GDP = T (L, K), and the LRAS curve, describe the process by which a decline in interest rates impacts the use of capital and economic growth.

3) Suppose your per capita production function is given as y = k". Capital evolves according to the expression Ak = sy – (n +d)k, and your consumption function is c = (1– s)y. As usual, s is the savings rate, n is the - population growth rate and d is the capital depreciation rate. Imagine a foreign government decides to grant your country an investment subsidy in the form of b, which represents a constant fraction of domestic investment per capita (ia) such that irotal = ia + bia. In per capita terms the expenditure function with the subsidy is y = c + itotal and it is y = c + ia without the subsidy. a) Derive an expression for the steady state capital stock after the subsidy is granted. (Hint: Use the expenditure function with the subsidy to solve for sy then use the expenditure function without the subsidy to solve for domestic investment ia.) b) Use the Solow diagram to show living standards before and after the subsidy is granted. Explain the dynamic process towards the new steady…
