The answer depends on the preferences and the measures of the ENGO. We use a bioeconomic objective function where fishers and regulator have ecological, economic, and social preferences, whereas the ENGO has only ecological preferences. Applying a Cournot model we analyze how the original regulation of the authorities is affected when an ENGO becomes involved. We use empirical data on fisheries stakeholder preferences and from the Portuguese and Spanish sardine purse seine fishery to calibrate and test the model. (JEL Q22, Q28)
