Let the Demand and Supply for Two Linked Products, Say

Multiple Choice

Let the demand and supply for two linked products, say corn and soy, be the following: Q_c^d= 12 - 2p_c + p_s; Q_c^s = 4+p_c; Q_s^d = 6-4p_s + p_c; Q_s^s = 4 + p_s. The superscript refers to "demand" (d) or "supply" (s) and the subscript refers to corn (c) or soy (s) . What are the equilibrium prices of corn and soy?

A) p_c = 2; p_s = 2
B) p_c = 1; p_s = 3
C) p_c = 3; p_s = 1
D) p_c = 1; p_s = 1
