RT Journal Article SR Electronic T1 The Implications of Environmental NGO Involvement in Fisheries Management JF Land Economics JO Land Econ FD University of Wisconsin Press SP 560 OP 573 DO 10.3368/le.90.3.560 VO 90 IS 3 A1 Margrethe Aanesen A1 Claire W. Armstrong YR 2014 UL http://le.uwpress.org/content/90/3/560.abstract AB What happens when an environmental NGO (ENGO) becomes involved in fisheries management, and its involvement is recognized by the managing authorities? 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)
