Economists David Laibson and Xavier Gabaix examined the behavior of consumers when buying
products that consist of a “base good” and “add–ons.” Firms typically compete on the price of the
base good (for example, a printer) rather than an add–on (for example, ink cartridges). They found
that firms are often successful in hiding the prices of add–ons from consumers. What explanation
do Laibson and Gabaix offer for why some firms do not offer lower–priced add–ons and advertise
the higher prices of rival firms?
Firms fear that competition for add–ons would force them to also lower the prices of their
base goods.
Firms fear that an ad campaign could lead to competition that would force all firms to lower
the prices of their add–ons.
The demand for add–ons is very inelastic. Lowering the price of add–ons would reduce total
revenue.
Using advertising to inform consumers who typically ignore the price of ad–ons is not a
profitable strategy.
The income effect of an increase in the price of salmon
is the change in the demand for other types of fish that results from a decrease in purchasing
power.
refers to the effect on consumer purchasing power which causes the consumer to buy less
salmon, holding all other factors constant.
is the change in the demand for salmon when income increases.
refers to relative price effect – salmon is more expensive compared to other types of fish –
which causes consumers to buy less salmon.
An article in the Wall Street Journal noted the following: Instead of relying on a full–coach,
round–trip unrestricted fare of about $2,000 between Cleveland and Los Angeles …Continental
[Airlines] since June has offered a $716 unrestricted fare in that market …. Through October, the test
resulted in about the same revenue that Continental thinks it would have collected with its higher
fare.
