NEXT Chapter 4: Demand KEY CONCEPT Demand is the willingness to buy a good or service and the ability to pay for it. WHY THE CONCEPT MATTERS *The concept of demand is demonstrated every time you buy something. Think of five goods or services that you have purchased. Which of them would you stop buying if the price rose sharply?

NEXT 7 2 important conditions of Demand 1. People are willing to purchase it 2. People are able to purchase it $200

NEXT So what influences YOU to purchase an item or not?

NEXT The Price As the price increases consumers buy less. P ↑, QD↓ P= Price QD= Quantity Demanded As the price decreases consumers buy more. P ↓, QD↑

NEXT 10 This is the Law of Demand There is an inverse relationship between a product’s price and the quantity demanded. *Law of demand explains consumer behavior as well as economic concept.

NEXT How do producers come up with these prices anyway?

NEXT Demand Schedules KEY CONCEPTS Demand schedule- a table that summarizes one consumer’s behavior *Lists how much of an item an individual will buy at each price

NEXT 13 Quantity Demanded to Price A Demand Schedule Price of Widgets Number of Widgets People Want to Buy $ $ $ $4.0040

NEXT Demand Curves KEY CONCEPTS Demand curve- a graph that shows amount of an item a consumer will buy at each price –Demand curves graphically show information found on demand schedules –Vertical axis shows prices –Horizontal axis shows quantities demanded –Demand curves slope down from upper left to lower right

NEXT 15

NEXT 16 What demand schedules and demand curves illustrate? Demand schedules show in table format the quantity of goods and services consumers are willing and able to purchase at each price in the market. Demand curves show in graph format the data listed in demand schedules How much of goods and services consumers will buy at a price

NEXT Determinants of Demand You will be able to explain how the markets, prices, and competition influence economic behavior. a. Identify and illustrate on a graph factors that cause changes in market demand.

NEXT What Factors Affect Demand? KEY CONCEPTS Law of diminishing marginal utility –marginal benefit of each additional unit declines as each unit is used Income effect –amount people buy changes as purchasing power of their income changes Substitution effect –amount people buy changes as they buy substitute products

NEXT Change in Quantity Demanded KEY CONCEPTS Change in quantity demanded –change in amount consumers buy because of change in price –each change shown by new point on demand curve –Does not shift the demand curve itself

NEXT Change in Quantity Demanded EXAMPLE: Changes Along a Demand Curve Individual demand curve –change in quantity demanded shown by movement to right or left along the curve Market demand curve –shows similar information for entire market

NEXT Change in Demand KEY CONCEPTS Change in demand is caused by a change in the marketplace –prompts people to buy different amounts at every price –also called shift in demand Six factors can cause change in demand

NEXT Non-Price Determinants of product demand shifts: C-onsumer tastes and preferences R-elated Goods Price/Complementary goods I- ncome M-arket Size E-xpectations (consumer) S-ubstitues

NEXT Change in Demand FACTOR 1 Consumer Tastes and Preferences Consumer tastes change; products gain and lose popularity Consumers demand a greater amount of popular items at every price Sellers advertise to create demand for products –i.e. Air Force Ones

NEXT Change in Demand FACTOR 2 Related Goods/Complements Complements—goods that are used together Rise in demand for one increases the demand for the other If price of one product changes, demand for both changes in same way –if price of one rises, demand for both will drop

NEXT Change in Demand FACTOR 3 Income A person’s ability to buy goods changes as his or her income changes As incomes of most consumers in a market change, so does total demand – Normal goods- demanded more when consumers’ incomes rise – Inferior goods- demanded less when consumers’ incomes rise

NEXT Change in Demand FACTOR 4 Market Size As number of consumers in an area changes, so does market size –i.e. Moody Air Force Base Demand for most goods changes as market size changes –rise in population leads to increased demand –decrease in population leads to decreased demand

NEXT Change in Demand FACTOR 5 Consumer Expectations Expectations about future price of items affect individual behavior –expected rise or fall in price can decide whether to buy now or wait Expectations of all consumers in a market affect demand –example: because cars go on sale at end of summer, demand goes up then

NEXT Change in Demand FACTOR 6 Substitutes Substitutes —products used in place of each other –if price of substitute drops, people buy it instead of original item –if price of original item rises, people will buy substitute $2 $1.50

NEXT Show What You Know! Georgia Milestone Practice Question When economics refer to “demand” they mean which of the following? How much satisfaction buyers receive from a purchase How much consumers will purchase at different prices How much sellers will supply at different prices How much people want the product if its free

NEXT Show What You Know! Georgia Milestone Practice Question Which of the following is an attempt by a firm to increase the demand for its product? the imposition of a price ceiling on the product an advertising strategy designed to change consumer tastes and preferences a marketing strategy to make the good scarce and therefore more expensive a production strategy to flood the market with the good or service

NEXT Show What You Know! Georgia Milestone Practice Question The principle that producers will only produce goods that will yield them a profit because it is something consumers want is known as the: Law of diminishing marginal utility Law of demand Equity price Price elasticity

NEXT SSEMI3c c. Define price elasticity of demand and supply. Determine and define vocabulary. Identify key terms within the standard. Define each term. ________________________________________

NEXT Scaffold understanding of the standard(s) and/or element(s). Paraphrase the standard(s) and/or element(s). Rewrite the standard including synonyms or brief definitions in parentheses and in a different color following the key terms found in step 1. Define price elasticity (resistance) of demand (want) and supply (quantity).

NEXT Elasticity of Demand SSEMI3c c. Define price elasticity of demand and supply.

NEXT Elasticity of Demand KEY CONCEPT Buying habits affected by type of product and importance to consumer Elasticity of demand –The degree or measure of how responsive consumers are to price changes

NEXT Elastic Demand 1.Elastic—quantity demanded changes greatly as price changes i.e. Cereal

NEXT Elastic Demand Slight change in price causes HUGE drops in demand.

NEXT Inelastic Demand 2. Inelastic—quantity demanded changes little as price changes i.e. Gas

NEXT Inelastic Demand Slight changes in price does little for demand

NEXT Difference between elastic and inelastic demand: Elastic demand- when a small change in a product’s price results in a significant change in the quantity demanded (i.e. price of pizza) Inelastic demand- when a change in a product’s price has only a slight effect on the quantity demanded (i.e. salt & gas)

NEXT What Determines Elasticity? Three KEY CONCEPTS affect elasticity of demand 1.availability of substitutes 2.proportion of income spent on good or service 3.whether product is a necessity or luxury

NEXT What Determines Elasticity? FACTOR 1 Substitute Goods or Services If no substitute for a product, demand tends to be inelastic –when price of insulin goes up, diabetics still need the same amount If there are substitutes for a product, demand tends to be elastic –when price of beef goes up, consumers can buy other meats

NEXT What Determines Elasticity? FACTOR 2 Proportion of Income Demand for expensive items tends to be elastic –if percentage of income needed to buy item increases, demand decreases Demand for inexpensive items tends to be inelastic –rise in price requires small additional part of income Rise in income can lead to greater demand for some goods or services

NEXT What Determines Elasticity? FACTOR 3 Necessity or Luxury Necessity—something needed for life –demand for necessities is inelastic Luxury—something desired but not essential –demand for luxuries tends to be elastic

NEXT Total Revenue Test KEY CONCEPTS Total revenue- amount of money company gets for selling its products –Formula: TOTAL REVENUE = P (price) x Q (quantity sold) Total revenue test- shows total revenue from item at various prices –if total revenue increases after price drops, demand is elastic –if total revenue decreases after price drops, demand is inelastic

NEXT Total Revenue Test EXAMPLE: Revenue Table Revenue table shows elasticity of demand by listing –prices at which item can be sold –quantity of item demanded at each price –total revenue received from sale of item at each price Valdosta Stadium Cinemas Quantity Demanded Total Revenue ($) $ ,500 $ ,000 $ ,000 $ ,000 $ ,000
