RT Journal Article SR Electronic T1 Spillovers in Regional Fisheries Management: Do Catch Shares Cause Leakage? JF Land Economics JO Land Econ FD University of Wisconsin Press SP 344 OP 362 DO 10.3368/le.92.2.344 VO 92 IS 2 A1 Cunningham, Sam A1 Bennear, Lori S. A1 Smith, Martin D. YR 2016 UL http://le.uwpress.org/content/92/2/344.abstract AB Regional councils manage U.S. fisheries. Fishermen can participate in fisheries managed by multiple councils, and effort controls in one region could lead to effort leakage into another. Theoretical modeling demonstrates that positive, negative, and no leakage are possible. Using difference-in-differences, we test for leakage across regional boundaries for a catch share program in New England and find evidence that the New England groundfish sector program caused spillover into adjacent Mid-Atlantic fisheries. Aggregate Mid-Atlantic harvest volume increased among sector members after the policy change. We find leakage in individual fisheries with similar gear and high market substitutability with sector species. (JEL Q22, Q28)
