Perfect Competition
n An efficient free market requires producers to be
operating under conditions of perfect competition.
This requires a stringent set of conditions - perfect
information, many buyers and sellers, a uniform
product and freedom of entry and exit.
n If producers do not operate in this way and, in
particular, if they have a significant power to influence
price or the total quantity being produced, then the
market will fail. Dentists and other suppliers of health
care often have this power.
