GOOGLE AS AN EXAMPLE OF
MONOPOLY POWER
• Google is an example of a firm with monopoly power.
– This means it has the ability to control price.

• Google is not a pure monopoly because it has some competitors.
– Yet it is so dominant in the market that it’s behavior is very different from the behavior of firms under perfect competition.
