Show how the profit-maximizing graph would differ for a firm if the city does away with the medallion system and allows new firms to enter the taxi business at will which leads to a large number of new entrants.

Solutions

Expert Solution




New cab drivers will enter the market only if they are cost-efficient enough to match the existing price P, which is the minimum of MC of all firms in a competitive market.

They take the demand curve as horizontal - supply however much they can for price P.
They decide their quantity Qc (taking price as exogeneous) such that [ MC(Qc) = P ]

This is shown as the point of intersection between the horizontal (competitive market's) demand curve D2 and the marginal cost curve MC.
