Principles of Microeconomics / Unit 8   MIC 0704 short lesson, about 20 seconds

Control of a Resource; Legal Monopoly

Captions available

The idea

Owning the only source of a key input keeps rivals out, as does a government grant of an exclusive right: a franchise, a license, a rule that only one firm may serve.

In practice

A single mine; the one licensed taxi company; first-class mail.

Where people slip

Legal monopolies are usually regulated in return, and licensing also limits supply in labor markets, as unit three noted.
