HO Mоdel: (20 pоints; 20 min.) The Stоlper-Sаmuelson Theorem stаtes thаt in the long run, an increase in the relative price of a good will increase the real earnings of the factor used intensively in the production of that good and decrease the real earning of the other factor. For this question you will be permitted to look away from the monitor for a short period of time and use a scrap piece of paper to do the math. Please show your work to the camera.Please answer the following questions using the information below.Computers: Sales revenue Pc x QC = $100 Earnings of labor W x LC = $50 Earnings of capital R x KC = $50 Shoes: Sales revenue PS x QS = $100 Earnings of labor W x LS = $60 Earnings of capital R x KS = $40Suppose the following: Computers: Percentage increase in price = ∆Pc/Pc = 5%Shoes: Percentage increase in price = ∆Ps/Ps = 0% Please solve for (1) the effect of higher relative price of computers on the rental of capital; and (2) the effect on wage for labor in each industry. That is, solve for: ∆R/R and ∆W/W Percent change in rent on capital can be expressed in the following general form: Computers: ∆R/R =(∆Pc/Pc)(Pc*Qc/R*Kc) - (∆W/W)(W*Lc/R*Kc)Shoes: ∆R/R =(∆Ps/Ps)(Ps*Qs/R*Ks) - (∆W/W)(W*Ls/R*Ks)
