ShiftDemandCh. 4.2 By Lauren Cantu
What it is • Refers to a shift in the demand curve • When the quantity demanded increases, curve moves right (vice versa) • Happens when ceteris paribus is dropped • “all other things (besides price) held constant”
What causes it • Income • Normal goods: Goods that consumers demand more of when their income increases. • Ex: new car vs. used car • Inferior goods: when income increases, demand for these goods fall (you can afford something better) • Ex: mac & cheese, generic cereals, used cars
What causes it • Consumer Expectations • If price is expected to increase in the future, there will be an immediate increase in demand. (vice versa) • Ex: sales • Population • Ex: WWII, Baby Boomers • Consumer tastes/Advertising • Campaigns, social trends, media influences
What causes it • Prices of Related Goods • Complements: two goods that are bought and used together • Ex: skis and ski boots • Substitutes: goods used in place of another • Ex: Snowboards and skis
Real World • Historically and currently, when gas prices have been predicted to rise, consumers will flock to gas stations before the prices rise (increase in demand)

Assessment True or False? • Shift Demand refers to the shift in demand curve. • A new car is an inferior good. • The curve will shift right if there’s an decrease in demand. • Substitutes are goods used in place of another. • Population is a factor that can cause shift.
