what does demand refer to
the quantity of a product that purchasers are willing and able to buy at various prices per period of time’.
We are focused on ‘Effective Demand’ and not ‘Notional Demand’.
what is law of demand
“As the price of a product falls, the quantity demanded of the product will usually increase, ceteris paribus”.
why does the demand curve slope downwards
Income Effect- As price goes up, people have less income so demand less. Substitute effect: as price increases, individuals will substitute for alternative goods.
Diminishing Marginal Utility
what is utility
Satisfaction received through consuming goods.
what is marginal utility
Extra Satisfaction gained from consuming another unit of a good.
what is diminishing marginal utility
Reduced rate of Satisfaction gained from consuming additional units of a good.
The lower satisfaction at higher quantity means a good is valued less and therefore people will pay less.
what are normal goods
goods & services that see a rise in demand when incomes rise.
what are inferior goods
goods & services that see a fall in demand when incomes rise
what does an increase in demand do to the graph
An increase in demand due to a non-price determinant will see the demand curve shift rightwards. (Outward)
what does a decrease in demand do to the graph
A decrease in demand will lead to the demand curve shifting leftwards
explain conditions of demand- income (normal goods)
For most goods, as income rises, the demand for the product will
also rise. Such goods are known as normal goods. As income rises,
the demand curve for a normal good will shift to the right. The size
of the shift in demand will depend upon the good itself.
explain conditions of demand- income (inferior goods)
If a product is considered to be inferior, then demand for the product
will fall as income rises and the consumer starts to buy higher priced
substitutes in place of the inferior good. Examples of inferior goods
may be cheap wine or “own brand” supermarket detergents.
As
income rises, the demand curve for the inferior good will shift to the
left. When income gets to a certain level, the consumer will be
buying only the higher priced goods and the demand for the inferior
good will become zero. Thus the demand curve will disappear
