Question

Transcribed Image Text:Third Degree Price Discrimination (=Group Pricing)
Dropbox observes that there are two types of demand for its storage services: business and private
individuals. The businesses' demand curve is QB = 200 – 2PB, where QB is the amount of storage
that businesses would like to purchase and Pg is the price charged per unit of storage (e.g. per
gigabyte) to businesses. The individuals' demand curve is Q1 = 50 – Pr, where Q1 is the amount
of storage that individuals would like to purchase and P¡ is the price charged per unit of storage
to individuals. Dropbox's cost function is given by C(Q) = 10Q + 100 where Q = QB + Q1.
1. Suppose Dropbox can price discriminate between the two groups. Calculate the amount of
storage it sells to each group, the two prices and total profits.
2. Calculate consumer and producer surplus under price discrimination
3. Suppose the government forbids price discrimination. Calculate the optimal unique price
the monopolist would charge and her profits. Would the monopolist choose to serve both
businesses and individuals?
4. Now calculate the consumer and producer surplus if price discrimination is forbidden. Using
total surplus as a measure of welfare, is society better off or worse off after this change is
introduced?
