Determinants of Demand and Supply
11. Determinants of Demand: Reasons for
Change/ Shift in Demand (SEPTIC) A
change in:
Price of Substitutes- things that replace each other:
pork v. beef, pinto beans vs. black beans, TV shows
and video rentals (If P of Substitute ↑, D for other
good ↑) (If P of A ↑, D for B ↑).
Consumer Expectations-if they expect a change in prices
or their income
Determinants of Demand and Supply
11. Determinants of Demand: Reasons for
Change/ Shift in Demand (SEPTIC) A
change in:
Population: Number of consumers, more or less
people
Consumer Taste- preferences, styles, fads, fashion, health,
advertising, popularity
Determinants of Demand and Supply
11. Determinants of Demand: Reasons for
Change/ Shift in Demand (SEPTIC) A
change in:
Income (y) (If Y ↑ , D ↑. If Y↓, D↓) Steak, Sports
Car
Price of Complements- things that go together: ketchup
and fries; movies and popcorn, cars and gasoline (If P of
Complement ↑, D for other good ↓) (If P of A ↑, D for B
↓).
Determinants of Demand and Supply
