| Over the relatively recent past, bioeconomic modelling has advanced by integrating major theoretical and analytical progress made in both economic and biological modelling. The movements from static towards dynamic models and from global towards analytical models were the first steps in this advance. More recently, research has turned towards veritable optimisation models incorporating risk, asymmetrical information, and chaotic and multiple equilibria. Attempts to validate such models have been based on case studies of more and more homogenous fisheries (jesmall numbers of stocks and exploitation systems) so that the objective function is quite explicit and limited.
