The Grand Lab has miraculously found a vaccine for the Covid-19 virus. The demand for the vaccine can be divided by high- and low-income groups with the following demand functions: High-income group: QH = 140-20PH Low-income group: QL = 220-40PL where QH is measured in the unit of millions of vaccines demanded by high-income groups at price PH, and QL is the number of vaccines demanded by low-income groups at price PL. Prices in both income groups are measured in USD. The cost of producing the vaccine if given by the following cost function C(QH, QL)= Qh + Q_- a. If the laboratory charges a single price, P7, to everybody, how many vaccines would be sold and to what price? How much profit would the Grand Lab make? b. How many vaccines would be sold to the high- and low-income groups respectively?

The Grand Lab has miraculously found a vaccine for the Covid-19 virus. The demand for the vaccine can be
divided by high- and low-income groups with the following demand functions:
High-income group: QH = 140-20PH
Low-income group: QL = 220-40PL
where QH is measured in the unit of millions of vaccines demanded by high-income groups at price PH, and QL is
the number of vaccines demanded by low-income groups at price
PL. Prices in both income groups are measured in USD. The cost of producing the vaccine if given by the
following cost function C(QH, QL)= Qh + QL.
a. If the laboratory charges a single price, P7, to everybody, how many vaccines would be sold and to what
price? How much profit would the Grand Lab make?
b. How many vaccines would be sold to the high- and low-income groups respectively?
c. Explain why the outcome above is inefficient and measure the inefficiency.
d. Suppose that the Grand Lab could accurately separate the low-income from the high-income group. Then
the Grand Lab would increase its profit by charging low- and high-income groups different prices. What
would be the quantity sold to each group and what would be the prices charged to each group? How much
profit would the Grand Lab make?
