MARKET FAILURE
PREPARED BY SANDREA BUTCHER
WELFARE MAXIMISATION
• Welfare is maximised when resources are allocated efficiently.
• This means that for each additional unit of output produced, the
extra cost incurred is equal to the extra benefit enjoyed
(SMC=SMB).

Welfare is maximised at QA, which is the intersection of SMC and SMB.
SO WHAT IS MARKET FAILURE?
DEFINITION
• Market failure refers to cases
where the market output
occurs at a level which does
not coincide with maximization
of welfare.
• The allocation of resources will
be inefficient.
• This means that the market
either overproduces or under
produces the product.
Suzie next door
always has
lemonade left over.
She is such a failure.
• Anytime that output occurs at a level where SMC ≠ SMB the
market will fail.
You will never
be my equal.
