A monopsonist’s revenue as a function of its only input is
R = az − bz2, z≥ 0
It is faced with a supply function for the input
z = α + βp, p ≥ 0
where p is the input price, and a, b, α, β > 0. Find the profit-maximizing price and quantity of the input the monopsonist will choose, and compare the analysis to that of the profit-maximizing monopoly
