On the same set of axes, draw "typical" smooth total productivity (TP),average productivity (AP) and marginal productivity (MP) curves forlabour and for land, and define the stages of production (assuming aperfect symmetry between the stages of production for labour andland under constant returns to scale).b) With reference to stage ll of production:i.Why does the producer operate only in stage ll?ii.What factor combination (within stage ) will the produceractually use? andil.where wil the producer operate:IfPubour =Pund?c)Economists identify key short run per unit cost curves comprising theaverage fixed cost (AFC), average variable cost (AVC), average cost(AC) and marginal cost (MC).On the same set of axes, draw these per unit cost curves.il.Explain the relationships among these per unit cost curves.
