Market Failures

,Roadmap
What are market failures?
When do they happen?
What are the consequences?
,Market failures and the environment
, The ideal world
In the best case scenario, a market equilibrium leads to the efficient
allocation
We have a private bread supply curve (private MC)
We have a private bread demand curve (private MB)
In equilibrium: supply = demand so PMC = PMB = price
For bread, the private costs and benefits are very likely the social costs and
benefits
