Microeconomics
2: Demand and supply
Demand
D: Quantity of G&S that consumers are willing and able to purchase at a given price in a given time period.
Law of demand:As the price of the product falls the quantity demanded of the product will rise, ceteris paribus. (negative causal relationship)
Why?
(1) Income effect:When price of a good falls then people will have increase in their "real income", so they can buy more of the goods.
(2) Substitution effect: When price falls, the product will become relatively more attractive to people than other products.
(3) Diminishing marginal utility:Consumer is willing to pay less for any additional good. Therefore it is more likely that consumers' marginal utility will correspond to price if the price is lower.
