Fishing for king crabs for a living is risky business. Their migration habits along the
Bering Strait are just not understood. The king crabs seem to disappear one year but
return mysteriously a few years later, wreaking havoc on the income of crabbers. When
crabs disappear, consumers buy lobster instead. What best describes this situation in the
king crab market?
A. The supply curve shifts to the left when crabs disappear (their price rises) and shift
to the right when they reappear (their price declines).
B. The supply curve shifts to the left when crabs disappear, (their price rises) and the
demand curve shifts to the left when consumers substitute lobster for crab (lowering
their price). The supply curve then shifts to the right when crabs reappear (their price
declines).
C. The price of crab rises when crabs are scarce creating excess demand. The price of
crab falls when crabs are abundant creating excess supply.
D. The quantity of crab falls and then rises as crabs disappear and reappear in response
to shifts in demand. Demand shifts to the left as consumers substitute toward lobster
when crab is scarce and shift to the right when crab is abundant.
