A simple bieconomic model (the Gordon-SChaefer model) is estimated for three species of tuna in the Eastern Tropical Atlantic. The model conformed well to the data and afforded estimates of maximum sustainable yield, bioeconomic and open access equilibria. Strong marginal stock effects were...

The development of offshore oil and gas, the mining of deep sea minerals and the disposal of wastes through ocean dumping have raised important questions about the way we harvest ocean resources and use the marine environment. From an economic perspective all of the above activities involve...
