Keizen and Tyke live in a small community in Cabarete in the Dominican Republic. For simplicity,
assume Keizen and Tyke are the only individuals in the community. Each has a demand for mosquito
control, given by the below equations. Mosquito control is provided at a constant marginal cost of $ 120.
Keizen's demand: Qdk=200-p
Tyke's demand: Qdt=180-2p
a) Draw out the demand curves Keizen and Tyke. If mosquito control is a private good, what is the
market demand curve? Draw out the market demand curve assuming mosquito control is a private
good. What is the equilibrium price and quantity of mosquito control?
