how markets work: price
what is market equilibrium?
where supply and demand are equal
what is consumer surplus?
the value that consumers gain from consuming a good or service over and above the price paid
what is producer surplus?
the difference between the price received by firms and the price they would have been willing to accept
what are the four functions of the price mechanism?
- rationing
- incentive
- signalling
- allocate
what is rationing?
where prices rise to ration-off excess demand; this means consumers will decrease the quantity demanded for this good
what is incentive?
where prices motivate firms (consumers) to take action e.g. for firms to increase quantity supplied
what is signalling?
where a price provides information (a signal) either for producers to consider whether to supply a good or for consumers to consider whether to purchase a good
what is allocate?
price allocate scarce resources among competing uses
what are rationing functions?
prices ration scarce resources when demand outstrips supply -> when there is a shortage, prices is bid up, leaving only those willing and able to pay to buy
what are incentive functions?
through choices, consumers send information to producers about their changing nature of wants and needs
what are signalling functions?
- if prices are rising due to high demand from consumers, this signals suppliers to expand production to meet higher demand
