market failures

In the book: in the service of the republic, the author talks about market failures. 

  • Externalities Where an external situation defines/effects a group in positive or negative ways. A university resulting in making city hotbed of innovation falls in externality. A factory emitting noise and smoke making neighborhood sick becomes a negative externality.
  • Asymmetric Information is found in situations where customers buy medicine with the premise that it is not adulterated. The fear of adulteration will change his buying behavior affecting manufacturers. 
  • Market power is when a bunch of companies owns the market. It is like Ola/Uber controlling the ride sharing. 
  • Public goods are the things that are non-rival and non-excludable like breathing air. 

I found it worth sharing.
