  1. Upcoming in Class Homework #8 Due Thursday Quiz #4 Thursday Nov. 17th Homework #9 Thursday Nov. 17th Group Outline due Thursday Nov. 17th Exam #4 Dec. 1st

  2. Homework #8 • 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. Homework #8 • 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. Homework #8 • What is the typical relationship between the economic optimum (EE), maximum sustained yield (EM), and the open-access equilibrium (EO)?

  5. Relationship between the Fish Population and Growth

  6. The Gordon-Schaefer Model

  7. Market Allocation in a Fishery

  8. The Price of Fish 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. Public Policies • 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

  10. CANADA'S PACIFIC COAST GEODUCK CLAM FISHERY

  11. ITQ Markets • 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

  12. Fisheries Problem Find the MSY, natural equilibriums, and identify the stable and unstable equilibriums Price = $1,000/ton Cost per Boat is $4,000

  13. Growth

  14. Problem

  15. Identify the following A natural state with no fishing industry A fishing industry obtaining the MSY from the fishery A fishing industry operating under an efficient management plan, with economically optimal returns A fishing industry characterized by open access.
