請問有人會這題嗎？

meeconomists believe thattheUS. _whole can be modeled with the following function, called the Copp-DortJas prodcfigj」 Y = 4K1/3L24, where Y is the amount of output, Kis the amount of capital, Lis the amount oflabor and 4isaparameter that measures the state oftechnology. For this produH function, the marginal productoflaboris MPL = (273) 4(K/D1人 Suppose that the price of outputPis2,4 1383.K5 1,000,000,and is 1000. The labor market 1 competitivez/ so labor is paid the value ofits marginal product- a. Calculate the amount of output produced Y and thie 3 dollar value ofoutput PP b. Calculate the wage Wand thereal wage W/P. (Note: The wage is labor compensation measured in do lars, whereas the real wage is labor compensatiorr measured in umits of output,) c. Calculate the labor share (the fraction of the value of output thatis paid to labor), whichis (WE)/(P29- d. Calculate what happens to output Y, the wage 區 the real wage W/選and the labor share (WD)/(PY) m each of the following scenarios: i.Inflation increasesPfrom 2to3. 貫Technological progress increasesA from 3tQ 和.
