Market
Structure
The market structure is the type of market in which a firm
operates. It is useful to know this for a firm, so that it can evaluate its
best strategy for pricing and how at what output to produce as well as how to
maximise its profits. The different types of market structures are summarised
in the table below.

At one end of the spectrum is perfect competition, firms are
prices takers and perfect competition is said to be an ideal market structure,
however some economists disagree with this. On the opposite end of the spectrum
is monopolies. Firms here are prices takers and have more control over price
setting than other types of market structures. Between these 2 points are
monopolistic competition, which sways more towards the perfect competition
side, and oligopolies which are closer to monopolies.
There are different levels of barriers to entry for firms
wishing to enter certain markets depending on their market structure. These
assumption and barriers are made below. It is also very hard to definitely say
what type of structure a market is under. A market may, for example, have only
one firm but yet have low barriers to entry. Therefore it isn’t always
conclusive as to what market structure a firm is under, and different arguments
can be put forward for this.
