Chapter 6 - Market fundamentals: demand Flashcards
what is demand?
we consider competitive markets, where the choices of individual consumers do not affect the price in the market – consumers are price takers
how to measure benefit?
The benefit a consumer gets is also their willingness to pay (WTP).
The maximum price a consumer will pay for a good is equal to the benefit they anticipate getting from the item (in money terms).
Generally, we expect marginal benefit to ?
decline with each additio`nal unit consumed (declining or diminishing MB).
When the consumer buys many units of a good, typical to have a
a continuous (smooth) MB curve
how to derive individual demand curve?
use a consumer’s marginal benefit curve
An individual’s demand is the
the quantity of a good or service that a consumer is willing and able to buy at a certain price.
the individual demand curve traces out all combinations of
(a) market price and (b) individual demand at that price, holding everything else constant.
A consumer will purchase units of the good up until the point where
P = MB
A demand curve represents
how much a consumer is willing and able to buy at different prices
law of demand
The downward slope of the demand curve means that a consumer consumes fewer units when the price is higher. This negative relationship between price and quantity demanded
The demand curve is derived by assuming that only price and quantity can change.
If there is a change in the price/quantity
there will be a movement along the demand curve
‘increase in the quantity demanded’.
If there is a movement downwards along the demand curve
‘decrease in the quantity demanded’.
If there is a movement up along the demand curve
A demand curve is drawn assuming all other relevant factors (other than the price of the good itself and the resulting quantity demanded) are?
held constant (ceteris paribus) These factors include the income, tastes, expectation and the prices of other related goods
what happens if factors other than price and quantity change?
the demand curve itself will shift in or out.
A shift of the demand curve is called a change in demand.
