Calculation of an efficiency within a market

A calculator of the overall effectiveness of competition in a particular market.

For instance, do we really have competition in the distribution of cable TV? There are lots of factors here:

Symptoms of a well functioning market:

• Lower price for service
• Number of service providers
• Fluidity in choice (is the market dominated by long term contracts?)
• Quality of information regarding choices
• The number of channels being distributed (quality channels vs. non-quality channels?)
• Offering of Pay channels
• Improved digital service

Conditions which market forces may have to deal with, in some cases these can be temporary

• Government Regulation
  • Restrictions on market size
  • Ability to restrict abusers of the system
  • Mandates on availability (of which there are none now)
  • Mandates to provide ala carte service?
• Natural disaster?

Note: A similar list could probably be done for cell phone service, and broadband service.

Close enough list for now.
