Competition or Cooperation? Peer Effects in the Pacific Coast Groundfish Fishery
利用2011-2014年太平洋海岸底层鱼类渔船的纵向数据，采用空间杜宾模型分析同伴效应，发现同港渔船间存在正溢出，但竞争也降低平均收入，且溢出效应小于龙虾和螃蟹渔业。
We analyze longitudinal data on vessel activity in the Pacific Coast groundfish fishery from 2011 to 2014, employing a spatial Durbin model with fixed effects. Different definitions of peers using port and risk pool membership allow identification of competition and cooperation under various groupings. Positive spillovers are strongest among vessels with a shared primary port. Competition also exists, as greater fishing intensity by peers negatively impacts average revenue. We find smaller positive spillovers than previous literature on lobster and crab fisheries, which have more sedentary spatiotemporal patterns. Thus, cooperatives within a single port or close neighboring ports may better serve groundfish fisheries. <i></i>
