Supply+and+Demand

Page 1: SUPPLY, DEMAND, AND WELFARE

Overview

  • Review of economic fundamentals focusing on the interaction of supply and demand.

  • Introduction to government interventions in microeconomics context.

  • Course identification: Econ 313: Lavender.

Page 2: OVERVIEW QUESTIONS

Key Inquiry Areas

  • What determines demand?

  • What determines supply?

  • How do supply and demand interact to create equilibrium?

Page 3: WHAT FACTORS AFFECT THE PRICE OF GASOLINE?

Influential Elements

  • Explore various factors influencing gasoline prices which can include: crude oil prices, production costs, government regulations, and market competition.

Page 4: FUNDAMENTALS OF MARKET

Market Dynamics

  • Market: where buyers and sellers interact.

  • Suppliers: providers of goods and services.

  • Transactions: exchange of goods for price.

  • Quantity: number of goods sold in the market.

Page 5: OREO ACTIVITY

Student Engagement

  • Activity designed to demonstrate supply and demand principles using Oreos as a case study.

Page 6: THE DEMAND CURVE

Insights into Demand

  • Quantity demanded: The amount of a good buyers are willing to consume at the current price.

  • Law of Demand: Inverse relationship between price and quantity demanded.

    • If price increases, quantity demanded decreases.

    • If price decreases, quantity demanded increases.

  • Example: Price of Oreos falls, leading to increased demand.

Page 7: THE DEMAND CURVE

Market Demand Dynamics

  • Market demand: the horizontal sum of all individual quantities demanded at each price.

  • Example combined consumption of Oreos by individuals Ned and Emma at different price points.

Page 8: THE DEMAND CURVE (Continued)

Price Points and Market Demand

  • Chart reflecting how individual demand translates to market demand at given prices for Oreos.

Page 9: SHIFTS IN THE DEMAND CURVE

Understanding Demand Changes

  • Quantity Demanded vs. Demand Changes:

    • Movement along the curve due to price changes.

    • Shift of the curve due to non-price factors.

Page 10: SHIFTS IN THE DEMAND CURVE

Understanding Shifts

  • Two perspectives on shifts:

    • Same price leading to different quantity demanded (left/right shift).

    • Same quantity demanded resulting in different willingness to pay (up/down shift).

Page 11: SHIFTS IN THE DEMAND CURVE

Shifting Factors

  • Reasons demand curve may shift:

    • Changes in preferences, consumer numbers, substitute/complement prices.

    • Changes in income, expectations, taxes, or subsidies.

Page 12: PRACTICE SHIFTS IN DEMAND

Application Scenarios

  • Analyze how various situations would affect the demand curve:

    • Price drop of peanut butter (a complement).

    • Seasonal health trends impacting cookie consumption.

    • Increasing gluten intolerance.

    • Rising prices of Oreos.

    • Economic recession effects.

    • Anticipated Oreos shortage.

Page 13: SUPPLY

Core Concepts of Supply

  • Quantity supplied: The amount producers are willing to sell at current prices.

  • Law of Supply: Direct relationship between price and quantity supplied.

    • If price decreases, quantity supplied decreases.

    • If price increases, quantity supplied increases.

Page 14: SHIFTS IN THE SUPPLY CURVE

Factors Influencing Supply Shifts

  • Factors that may cause shifts in the supply curve include:

    • Changes in production input prices, technology, number of sellers, and producer expectations.

Page 15: WHAT IS THE MARKET?

Understanding Market Scope

  • Concept of product differentiation and market scope.

  • Discussion on the realism of demand curve modeling.

Page 16: SUPPLY PRACTICE

Supply Scenarios

  • Analyze potential outcomes in pizza supply as influenced by cheese prices.

  • Evaluation of various scenarios affecting the orange supply curve.

Page 17: BRINGING SUPPLY AND DEMAND TOGETHER

Equilibrium Pricing

  • Equilibrium price: Occurs when quantity supplied equals quantity demanded.

  • Concept of market clearing price and its significance.

Page 18: BRINGING SUPPLY AND DEMAND TOGETHER

Price Dynamics in Market

  • Law of Supply and Demand: Market price adjusts to balance supply and demand.

    • Shortage: Demand exceeds supply, leading to price increases.

    • Surplus: Supply exceeds demand, resulting in price decreases.

Page 19: RIGHTWARD SHIFTS & EQUILIBRIUM

Effects of Demand Increases

  • Impact of demand increase leading to higher equilibrium price and quantity.

  • Effects of supply increases reducing equilibrium price while increasing quantity.

Page 20: LEFTWARD SHIFTS & EQUILIBRIUM

Effects of Demand and Supply Decrease

  • Demand decrease leads to lower equilibrium price and quantity.

  • Supply decrease results in higher price and lower quantity.

Page 21: GRAPHING EQUILIBRIUM IMPACTS

Graphical Analysis Tasks

  • Situational analysis for graphing impacts on the Oreo market; determine price and quantity responses based on various economic factors.
