Scope and compatibility of measures in international fisheries agreements� uses game theory and bioeconomic modelling to break important ground and provides a real contribution to the economics of international fisheries agreements (IFAs). In this comment we wish
to raise two issues relevant to the modelling framework used in the article that is one widely adopted in this area. The first is whether the model�s fish movements, specified by a diffusion parameter, accurately portray fish movements. We argue that the biological evidence does not support the assumptions made in the article for many, possibly most fish species. The second is the specification of production technology in the model giving maximum economic yield (MEY) and corresponding resource stock (BMEY). We argue that the assumptions made in the article are not consistent with current practice and empirical evidence.
