The term 'surplus' is used in
economics for several related quantities. The
consumer surplus is the amount that consumers benefit by being
able to purchase a product for a price that is less than they would be
willing to pay. The
producer surplus is the amount that producers benefit by selling
at a market price that is higher than they would be willing to sell for. Note that producer surplus flows through to the owners of the
factors of production, unlike
economic profit which is zero under
perfect competition. If the markets for factors are perfectly competitive as well, producer surplus ultimately ends up as
economic rent to the owners of
scarce inputs such as
land.
Details
On a standard
supply and demand diagram, consumer surplus shows up as a triangle above the price and below the demand
curve, since
intramarginal consumers are paying less for the item than the maximum that they would pay.
Producer surplus shows up as a triangle below the price and above the supply curve, since that is the minimum that a producer can produce that quantity with.
If the
government intervenes, using, for example, a tax or a subsidy, then the graph of supply and demand becomes more complicated and will also include an area that represents 'government surplus.'
Combined, the consumer surplus, the producer surplus, and the government surplus (if present) make up the 'social surplus' or the 'total surplus'. Total surplus is the primary measure used in
Welfare Economics to evaluate the efficiency of a proposed policy.
A basic technique of
bargaining for both parties is to pretend that their surplus is less than it really is: sellers may argue that the price they asks hardly leaves them any profit, while customers may play down how eager they are to have the article.
In
national accounts,
operating surplus is roughly equal to distributed and undistributed pre-tax
profit income, net of depreciation.
In
heterodox economics, the economic surplus denotes the total income which the
ruling class derives from its ownership of scarce
factors of production, which is either reinvested or spent on consumption.
In
Marxian economics, the term ''surplus'' may also refer to
surplus value and
surplus labour.
