Let the demand and supply for two linked products, say corn and soy, be the following: $Q _ { c } { } ^ { d } = 12$ $- 2 p _ { c } + p _ { s } ; Q _ { c } { } ^ { s } = 4 + p _ { c } ; Q _ { s } ^ { d } = 6 - 4 p _ { s } + p _ { c } ; Q _ { s } ^ { s } = 4 + p _ { s }$. The superscript refers to "demand" (d) or "supply" (s) and the subscript refers to corn (c) or soy (s). Now, suppose that the demand for corn shifts to $Q _ { c } { } ^ { d } = 18 - 2 p _ { c } + p _ { s }$. If the price of soy does not adjust in response to this shift, what is the new equilibrium price of corn?
A) $p _ { c } = 2$
B) $p _ { c } = 1$
C) $p _ { c } = 3$
D) $p _ { c } = 5$

The Answer of Let the demand and supply for two linked products, say corn and soy, be the following: $Q _ { c } { } ^ { d } = 12$ $- 2 p _ { c } + p _ { s } ; Q _ { c } { } ^ { s } = 4 + p _ { c } ; Q _ { s } ^ { d } = 6 - 4 p _ { s } + p _ { c } ; Q _ { s } ^ { s } = 4 + p _ { s }$. The superscript refers to "demand" (d) or "supply" (s) and the subscript refers to corn (c) or soy (s). Now, suppose that the demand for corn shifts to $Q _ { c } { } ^ { d } = 18 - 2 p _ { c } + p _ { s }$. If the price of soy does not adjust in response to this shift, what is the new equilibrium price of corn?
A) $p _ { c } = 2$
B) $p _ { c } = 1$
C) $p _ { c } = 3$
D) $p _ { c } = 5$
