The production function of a country is given by a neoclassical production function: Y₁ = K¹5 (A+N+)0,5. In this country, real interest rate is r=0,06, the depreciation rate is d=0,04, the level of technology A is equal to 1 and current employment N is equal to 100; the price of capital goods is PK = 4 and the general price level is P=2. Refer to the neoclassical model of investment to calculate the desired level of capital stock and gross and net investments, if the actual level of capital stock is equal to 150. (5p) a) Refer to the neoclassical model of investment and use a relevant graph (with K on a horizontal axis and MPK and us on the vertical axis) to show, what will happen to the desired capital stock as a result of the increase in the level of technology A (2,5p).
