Monopsony power exists when a single buyer or an association of buyers can dictate the prices they
pay to suppliers, or control other aspects of the relationship that exists between themselves and their suppliers.
Monopsony power in labour markets
In the case of labour markets, monopsonists can exert their buying power in
a number of ways, including:
- Setting wages below the market equilibrium.
- Determining the number of workers they hire - which may be below the market
level of employment.
- Reducing the security of employment by offering contracts which do not
guarantee a particular number of hours of work.

Monopsony power in
- In terms of product markets, monopsonists can similarly exert their buying
power in serveral ways, including:
- Setting prices lower that in a competitive market with many competing
- Requiring suppliers to cover costs which typically the buyer might
pay, such as packaging, labelling and advertising costs.
- Forcing suppliers to make
lump sum payments to the monopsonist, for example, for access to particular positions in stores and
outlets, or to pay for product wastage.
- Delaying payments to suppliers to improve the monopsonist's cash flow.
Measures to control monopsony power
Governments and regulators, can attempt to control monopsony power in
several ways, including:
- Setting up a specific regulator to monitor the activities of firms with
monopsony power, such as the UK's
Groceries Code Adjudicator (GCA). The GCA,
which adjudicates on issues relating to the
groceries supply code of practice, came into force in 2013 and monitors
the trading practices of the 10 regulated grocery retailers that have an
annual turnover of more than £1 billion, and promotes what it calls
'fair dealing' in the supermarket sector.
- Fines for firms exploiting monopsony power,
such as the fines that can be imposed by the GCA. The GCA can impose fines
of up to 1% of their annual UK turnover.
- Controlling prices paid to suppliers - such as setting minimum prices.
- Subsidising suppliers who are adversely affected by the
exertion of monopsony power.
- Legislate against late payments.
- Prevent further monopsony power by blocking mergers or by forcing firms to
divest outlets or divisions of their business.
- Measures designed to encourage new entrants into the industry.
