1.2.8 +1.2.10 consumer/producer surplus, consumer behaviour Flashcards
what are the two assumptions in econimics ?
- consumers wish to maximise utility
- firms wish to maximise profit
what is ‘utility’?
the hapiness recieved
* the satisfaction/ benefit derivd from consuming a good
why may consumers not act rationally?
- herd behaviour
- habitual behaviour
- weakness at computation
so they don’t switch
what do economic agents require to make rational decisions?
- time
- information (otherwise information gaps are created)
- ability to process information
show consumer surplus on a graph
were willing to pay more, but equilibrium is less
show the producer surplus on a graph
what is the price mechanism?
the interaction of supply and demand to determine prices
what are the functions of the price mechanism?
- signalling
- rationing
- incentivising
prices have fallen. (to eliminate excess supply)
Describe the signalling function of the price mechanism
- decrease in price signals to producers that consumrs want fewer goods
- therefore it signals to reduce the quantity supplied
extension in supply (along the curve)
Prices have risen (to eliminate excess demand).
Describe the incentivising function of the price mechanism
- prices are increasing, this increases the incentive to supply as more profit can be made
- therfore there is an increase in quantity supplied
extension in supply (along the curve)
Prices have gone up (excess demand).
Describe the rationing function of the price mechanism
- fewer consumers are willing and able to demand high prices
- decrease in quanity demanded
contraction in demand
what does rationing do?
limit/ration the quanity demanded by consumers
what is the price transaction ?
the transaction between the consumer and producer
Define producer surplus
The difference between the price forms are willing to sell the good for and the market price it is sold at.
(Area above the supply curve and below the equilibrium price)
Define consumer surplus
The difference between the price a consumer is prepared to pay for a good and the actual price.
(Area above the equilibrium price and below the demand curve)
