All of Microeconomicsin one slide: You Buy Something when: Firms produce another unit when: MB ≥ MC MR ≥ MC Firms purchase anotherinput when: MRP ≥ MFC
MR = MC MRP = MFC ----------- ------------- Product Market & Factor Markets MFC MRP Market for OUTPUTS Market for INPUTS
Supply curve MFC MRP Demand & Supply of Factors • MRP is the demand curve for input • MP input X price output • MFC is the supply curve for inputs • Cost of input • Most firms are competitivein the factor market (input market) • So they are “wage takers” in the labor market. • This means a firm has a horizontal supply curve (perfectly elastic) • i.e. price is fixed

MRP2 Shifts in Labor Demand Demand Curve shifts right when: • Demand for Product • Productivity • Technology, working conditions, etc... • Price of other resources: • Price ↓ of complementary resource • Price ↓ of substitute resource MRP • “It Depends” • Two different effects when the price of substitute falls: • Substitution Effect- you hire less workers • Output Effect- MC falls, so output increases => you hire more workers
