| 説明 | view sourcecode, Reed.R lab group commented that optimum in Reed model looks unrealistic due to frequency with which it shuts down all fishing. This is an artifact of not having extraction costs increase sufficiently for small catch, and can be easily fixed by increasing that cost (c in the profit eq, profits-costs = p*x-c/x) |
