Economic diversity of Maine's American lobster fishery

Maine's coastal communities critically depend on the American lobster fishery, which is now exposed to ocean warming. There is uncertainty about the future robustness of the stock and the economic performance of the fleet appears vulnerable. This research characterizes economic heterogeneity in Maine's fishing fleet using latent class stochastic profit frontier analysis. We explore the diversity of business models and examine how they are associated with the economic performance of the fleet in the prewarming period. The study uses unique firm-level data that capture the operational and economic information of the harvesters in the year 2010, the year before the reported environmental change in the Gulf of Maine. Our findings indicate that economic efficiencies differ based on their choice of business models and it was found that technical upgrades generally contribute to improved economic performance in the prewarming period. Reported societal benefits associated with employment levels have characterized the lobster production environment over firm-level efficiency. This research establishes a critically important baseline for future comparison and quantification of policy reforms within the US lobster fishery.

Introduction It has been argued that fisheries managed in congruence with the basic social and economic systems of the fishing community can generate effective comanagement decisions designed to promote the [...]
