In a fishery the long-run harvest function (harvest volume) is H(E) = aE – bE², with a, b representing positive constants and E is fishing effort. Total cost is TC(E)= cE, with c being the unit cost of effort. Total revenue is TR(E) = pH(E), with p being the constant price of fish.

Question
In a fishery the long-run harvest function (harvest volume) is
H(E) = aE – bE², with a, b representing positive constants and E is fishing effort.
-
Total cost is TC(E)= cE,with c being the unit cost of effort.
Total revenue is TR(E) = pH(E), with p being the constant price of fish.
Suppose that, because of an increase in world demand, the price of the fish from this fishery rises
significantly.
• Illustrate and explain the impact of this price-increase on the fish stock and the competitive
level of effort (or employment) in the fishery.
What can be said about the long-run impact on the fish catch? Is it positive,
negative, or indeterminate? Explain.
