2
What is the difference between a stable and an unstable equilibrium in the population of a fishery? Use a graph to support your answer. Where does the maximum sustained yield occur in your graph?
3
Use a graph with a total cost curve and a total revenue curve for a fishery to show the difference between the economically optimal harvest, the maximum sustained yield, and the open-access equilibrium.
4
What is the typical relationship between the economic optimum (E E ), maximum sustained yield (E M ), and the open-access equilibrium (E O )?
8
If the price of fish increases, total revenue will increase, shifting the open-access equilibrium higher and the stock of fish lower. As stocks deplete, we move closer to the minimum viable population. Lower stocks imply more scarcity and higher prices.
9
Private Ownership Raise the Real Cost of Fishing NB =0 Permits or Taxes Welfare transfer to government ITQs (Individual Transferable Quotas ) Welfare depends on initial winners and losers
11
ITQs Allocation Auction Grandfathering Lottery Efficient ITQ Market Quota entitles holder to catch a specified amount of the total authorized catch Catch authorized is equal to the efficient catch for the fishery Quotas should be freely transferable among fishermen
