History shows that these policies lead to shortages and stagnation;
so why do we want to control prescription drug prices?
The Problems
of Price Controls

By FIONA M.

U NE OF THE MOST IMPORTANT
issues to Americans is how to manage
prescription drug prices, especially
for seniors who depend on Medicare
coverage. Some policy advocates are
urging the federal government to con-
tract directly with drug manufacturers to purchase drugs for
seniors - at prices set by the government. Despite the high-
minded intentions of these advocates, such price controls
could be very harmful to Americans' future health.
When prices are held below natural levels, resources
such as talent and investor capital leave an industry to seek
a better return elsewhere. This means that there will be
less discovery and innovation, and fewer new drugs will
become available to consumers. Often this change hap-
pens over the long term - longer than the tenure of any pol-
icymaker.. Thus, it is vitally important to remind policy-
makers of the effects of price controls whenever they are
proposed as government policy.
DISRUPTING SUPPLY AND DEMAND
THE DETERMINING OF MARKET PRICES THROUGH THE
dynamic interaction of supply and demand is the basic
building block of economics. Consumer preferences for a
product determine how much of it they will buy at any
given price. Consumers will purchase more of a product as
its price declines, all else being equal. Firms, in turn, decide
how much they are willing to supply at different prices. In
general, if consumers appear willing to pay higher prices for

a product, then more manufacturers will try to produce the
product, will increase their production capacity, and will
conduct research to improve the product. Thus, higher
expected prices lead to an increased supply of goods. This
dynamic interaction produces an equilibrium market price;
when buyers and sellers transact freely, the price that results
causes the quantity demanded by consumers to exactly
equal the supply produced by sellers.
But when government adopts a price control, it defines
the market price of a product and forces all, or a large per-
centage, of transactions to take place at that price instead
of the equilibrium price set through the interaction between
supply and demand. Since supply and demand shift con-
stantly in response to tastes and costs, but the government
price will change only after a lengthy political process, the
government price will effectively never be an equilibrium
price. This means that the government price will be either
too high or too low.
When the price is too high, there is an excessive amount
of the product for sale compared to what people want. This
is the situation with many U.S. and European farm pro-
grams; government, in an effort to increase farm incomes,
purchases the output that consumers do not want. This, in
turn, prompts farmers to raise more cows and convert
more land to pasture or cropland. However, the higher
prices discourage consumers from buying farm products,
causing an excess of supply (e.g. a butter mountain). Gov-
ernment then exacerbates this situation by continuing to
purchase the excess crop at the set price.
Serious problems also result when government sets
prices below the equilibrium level. This causes consumers
to want more of the product than producers have avail-
able. When the federal government restricted gasoline price
