Derived Demand of the Factor Market
Homework: FRQ #1 Imperfect Competition Quiz Make-Ups!!!!!! Must be done ASAP!!!!!!!! Derived Demand of the Factor Market Students will demonstrate understanding of demand in the factor market by analyzing a set of scenarios and drawing conclusions in relation to their effect on wage rate and quantity of workers hired
2
Brainstorm… ALL ABOUT THE MARGINAL PRODUCT/REVENUE OF THE RESOURCE!
Based on your knowledge about the factors that shape the demand for labor in the resource market: Why does a professional baseball player make more money than a teacher? Why does a doctor make more money than a janitor? Why does an engineer make more money than a waitress? ALL ABOUT THE MARGINAL PRODUCT/REVENUE OF THE RESOURCE!

Derived Demand for Labor
The demand for a firm’s output and the firm’s demand for labor are directly related Product Market: Firm’s Output Labor Market: Firm’s Input S D Price QO P QE S = MRC D = MRP WE QH Wage QL
4
Derived Demand for Labor
If demand for the output increases, demand for the input must increase Product Market: Firm’s Output Labor Market: Firm’s Input S D Price QO P QE S = MRC D = MRP WE QH Wage QL Price of the output increases! Wage rate for the labor increases! Quantity of the output increases! Quantity of labor increases! W2 P2 D2 = MRP2 D2 Q2 Q2
5
Shifts in the Demand for Labor (Market)
Demand = MRP… MRP = MPL × P Change in price of firm’s output: Demand in product market increases Price of firm’s output increases When price increases, MRP increases labor’s product is now more valuable! Wage rate will increase and quantity of workers will increase!
6
Shifts in the Demand for Labor (Market)
Demand = MRP… MRP = MPL × P Change in the supply of other inputs: Supply of crucial input, say land for a farmer increases Given the same quantity of workers, each can now product more output, ceteris paribus If MPL increases, MRP increases increase in the demand for labor Wage rate will increase and quantity of workers will increase!
7
Shifts in the Demand for Labor (Market)
Demand = MRP… MRP = MPL × P Changes in technology* 99% of the time technology increases demand for labor Farmer invests in new, automated reaper… Given the same quantity workers, each can product more output, ceteris paribus If MPL increases, MPR increases demand for labor increases Wage rate will increase and quantity of workers will increase!
