price determination and price mechanism Flashcards
what is equilibrium
when supply = demand
what is the role of market forces
to remove excess supply or demand
what is excess supply
supply greater than demand
what is the price mechanism
allocates goods and services to get equilibrium
three functions of price mechanism
incentive function
signalling function
rationing function
incentive function meaning
higher prices incentivise firms to produce more goods as it will cause higher profits
signalling function meaning
changes in price show changes in supply/demand and thus acts as a signal, e.g. high price signals that there is high demand
rationing function meaning
if there is high demand and supply is limited, price will be high to ration the supply. works the other way too with low demand excess supply
advantages of the price mechanism
efficient allocation of resources
no cost to regulate it or operate - its natural
prices are kept to their minimum and resources are used as efficiently as possible
disadvantages of the price mechanism
inequality in wealth and income likely
under the provision of merit goods and overprovision of demerit goods as the equilibrium will not be at the socially optimum level
