Q

What is involved in the rationing function?

A
  • Prices rationed to reach market equilibrium
  • e.g. if consumers demand a good and supply is relatively scarce, prices will be high to ration the excess demand
    If demand is low and supply is relatively high then prices will be low. The low prices reflect the scarcity of the good.

Q

What is involved in the signalling function?

A
  • The Price of a good is a key piece of information to buyers and sellers in the market. They act as a signal to the market.
  • Decisions about buying and selling are based on these signals
  • The change in prices signals to both buyers and sellers should change quantity bought and sold
  • Suppliers are incentivised by high prices to supply and consumers will consume less at a higher price

Q

What is involved in the incentive function?

A
  • Price acts as an incentive for buyers and sellers.
  • Low prices encourage buyers to purchase more goods. This is because the amount of utility gained per pound spent increases relative to other goods
  • And higher prices discourage buyers to consume
  • High prices encourage suppliers to supply and low prices discourage production

A

Occurs where consumer satisfaction is maximised in the production of goods and services. At this point the quantity supplied will be equal to the quantity demanded (market equilibrium)
