Rent-Seeking in the U.S. Atlantic Sea Scallop Fishery

Creator:: Edwards, Steve F.
Abstract:: Rent-seeking in the U.S. Atlantic sea scallop fishery is described. Resource and trade disputes caused the U.S. fishing industry, including scallopers, to lobby Congress for extended federal jurisdiction in 1977. The sea scallop fishery soon overcapitalized as fishermen captured non-exclusive resource rents. Limited entry was introduced in 1994, but an...

Common Pool Politics and inefficient Fishery Management

Creator:: Hoffmann, Julia and Quaas, Martin F.
Abstract:: The main instrument used in fishery management is the total allowable catch (TAC). Fishery management often fails because TACs are set too high and do not sufficiently restrict fisheries. The question we address in this paper is why do decision makers choose inefficiently high TACs? Our approach is to model...

Growth Overfishing

Creator:: Diekert, Florian K.
Abstract:: Growth overfishing squanders large parts of the potential rents in fisheries. Many of today’s fisheries are characterized by a severely truncated age-distribution, which in addition may have irreversible ecological consequences. Nevertheless, the implications of age-differentiated harvesting for management have received surprisingly little attention in the literature. In the present paper,...
