Topic 2 - Demand Micro Flashcards
Demand
The quantity of a good or service that customers are willing and able to buy at a given price in a given time period
Demand curve
Shows relationship between price of an item and quantity demanded over a period of time
Why does the demand curve slope down?
(Income effect)
-When price falls, the real income of consumer rises
-Increases purchasing power, allows more of that good to be bought
(Substitution effect)
-When price falls, it becomes cheaper relative to its substitutes
-Consumers switch from more expensive substitutes
(Diminishing marginal activity)
Each extra unit of a good or service will eventually give less extra satisfaction.
