Chapter 13 PPT

Chapter Thirteen: Factor Markets (Labor Market)

Icebreaker Activity

  • Class divided into pairs for job interview simulations.

  • Discuss hiring decisions and salary requirements.

  • Share one sentence summary of conclusions with the class.

Chapter Objectives

  • Calculate Marginal Product of Labor: Analyze data on production technology.

  • Labor Demand Determinants: Explain impacts of changes on labor demand.

  • Labor Supply Determinants: Explain impacts of changes on labor supply.

  • Equilibrium Wage and Labor Quantity: Determine in the labor market.

Demand for a Factor

  • Demand derived from other demands (e.g., demand for products).

Marginal Revenue Product (MRP)

  • Derived Demand: Demand from the need for products.

  • MRP Calculation:

    • MRP = ΔTR / ΔQ

    • MRP = MR x MPP

Calculating MRP

  • Two methods for calculating MRP given:

    1. MRP = ΔTR/ΔQ

    2. MRP = MR x MPP

  • Example data showcasing output and MRP calculations.

Firm's Factor Demand Curve

  • MRP curve equates to the factor demand curve.

Value Marginal Product (VMP)

  • VMP Calculation: VMP = Price of good x Marginal Physical Product (MPP).

  • MRP equals VMP under perfect competition; VMP > MRP for non-perfect competition.

Marginal Factor Cost (MFC)

  • MFC equals price x MPP.

  • Factor Price Taker: Firm that can buy unlimited factor at equilibrium price.

Equating MRP and MFC

  • Firms should buy until MRP = MFC.

  • Least-Cost Rule: MPP of factors should be equivalent when normalized by price.

Knowledge Checks

  • Questions assessing understanding of MRP, MFC, and cost minimization.

The Labor Market

  • Shifts in demand and supply curves depend on various factors, including productivity and wage changes.

Elasticity of Demand for Labor

  • Formula: EL = %ΔQdL / %Δw.

  • Determinants include demand elasticity for products, ratio of labor costs, and availability of substitutes.

Supply of Labor

  • Market Supply: Quantity supplied rises with wage rate.

  • Individual Supply: Influenced by substitution and income effects.

Supply and Demand of Labor

  • Changes in quantity supplied relate to wage rates.

  • Outlined factors influencing shifts in supply and demand equilibrium.

Differences in Wage Rates

  • Homogeneity of labor and job characteristics affect wage differences.

Differences in Supply and Demand

  • Labor demand influenced by worker abilities and effort; supply reflects job characteristics.

Marginal Productivity Theory

  • Firms pay factors according to their marginal revenue products.

Knowledge Checks Review

  • Practice assessments to reinforce understanding of wage influences and labor demand shifts.

Chapter Summary

  • Key learnings include calculation of marginal product of labor, impacts of labor demand/supply changes, and determination of wage and labor quantity in markets.
