Answer:
No shift in the demand-supply curve
Step-by-step explanation:
There will be an increase in demand,since the available supply will be limited.
Meanwhile, no shift in a demand or supply curve occurs when a good's quantity demanded or supplied does not changes even though price remains the same. For instance, if the price for the lobster was $2 and the quantity of beer demanded does not change from Q1 to Q2, then there would be no shift in the demand for lobster. Shifts in the demand curve imply that the original demand relationship has changed, meaning that quantity demand is affected by a factor other than price,which in this case is none,since the damage of the fishing boats does not affect the collection of trapped lobsters. No shift in the demand relationship would occur if, since the boat are not needed to get lobsters.
