1) Norgaard and Trosper both place value on both extractive and preservation activities. How is
it that Trosper’s model results in an annual yield that is less than the maximum sustainable yield
and a stock of wood fiber that is less than the maximum capacity of a forest? Be sure to explain
the variables and include a graph.
2) Larson, Smith and Smith studied the possible forest management practices. Is it likely that tax
revenues can solve the forest dilemma in the Rocky Mountains? What alternative strategies
might be developed? Are there significant roadblocks to these strategies?
3) When looking at a renewable resource such as fisheries, explain what is meant by a sustainable
yield. Explain different Open access and Limited access policies that have been attempted to
avoid the tragedy of the commons in the fisheries. Is there evidence that one policy type is more
successful? See Example 12.3
4) Why does Jacobs focus on the idea of a conduit? What are the components of the conduit and
why is it important? How does this model allow us to think of the issues of sustainability and
environmental economics?
5) What do you think Boulding would say about Jacobs’ conduit model? How does the idea of
entropy come into play in the conduit?
