Oligopoly: The Case of Lysine, 1994
Characteristics of Oligopoly
1) Small number of Sellers
2) Similar or identical products
3) Firms know one another—oscillate between being
incentive to cooperate and act like monopoly
incentive to cheat on one another
friends and foes

Lysine Cartel
fixed costs of $15 million per year.(2) MC of producing lysine was $0.60 per
Assumptions: (1) Two firms had identical plants with
pound at all levels of output, i.e., plants were never operated close to capacity.
(3) Market demand for lysine in 1994 was:
P = 1.80 – Q1.80720

What did the Lysine Cartel do?
(1) Fix Prices
(2) Set Quotas (Q) for 2 Firms
