Entry, exit, and supply curves: Constant costs

Note: This is post #45 in a weekly video series on basic microeconomics.

Industries that have a flat supply curve are called “constant cost” industries. An example is domain name registration: to increase the supply of domain names, we must only increase the inputs by a negligible amount. That is why even as the Internet expands so rapidly, says Alex Tabarrok, it still costs only about six or seven dollars to register a new domain name. By showing you how these industries respond to an increase in demand, we can explain why they are constant cost industries.
