4.6. LAUNDRY DETERGENT. The market for laundry detergent is monopolistically compet-
itive. Each firm owns one brand, and each brand has effectively differentiated itself so
that it has some market power (i.e., faces a downward sloping demand curve). Still, no
brand earns economic profits, because entry causes the demand for each brand to shift

Suppose that the government does a study on detergents and finds out they are
all alike. The public is notified of these findings and suddenly drops allegiance to any

market?

that the perfect competition model may be considered a good approximation. Currently
the market demand curve is given by Q = 120-1.5 p, whereas the market sup
given by Q=-20+2 p.
