This paper presents empirical evidence of production distortions under controlled access management in the Mid-Atlantic surf clam and ocean quahog fishery. Results indicate that vessels harvested multiple clam species even though the harvest technology exhibits diseconomies of scope. Vessels...

Pooling diversified and specialized firm data to analyze multiproduct cost technologies raises two issues in applied research: (1) a functional form must be specified that accommodates zero outputs, and (2) assumptions must be made regarding the structure of the multiproduct technology when some...

Regulations to reduce bycatch of non-marketed marine species often impose gear restrictions, reductions in harvest of the target species, and/or spatial and temporal closures of the fishing ground. These regulations can exact significant social costs in commercial fisheries. We evaluate...

We study harvesting efficiency and the problem of discards under harvest uncertainty in a fishery that is managed with quotas. With only idiosyncratic harvest uncertainty, we show that frictionless post-harvest quota trade can achieve full efficiency and eliminate quota-overage discards...

We present a dynamic game of search and learning about the productivity of competing fishing locations. Perfect Bayesian Nash equilibrium search patterns for non-cooperating fishermen and members of an information sharing cooperative are compared with first-best outcomes. Independent fishermen...

We consider the problem of multi-species fisheries management when targeting individual species is costly and at-sea discards of fish by fishermen are unobserved by the regulator. Stock conditions, ecosystem interaction, technological specification, and relative prices under which at-sea...
