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

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
