Location Choice in New England Trawl Fisheries: Old Habits Die Hard
用随机效用模型估计新英格兰大型拖网渔船的渔场选择行为,检验从船长访谈中提炼的行为模型,发现传统习惯比利润均等化假设更能解释实际选择。
In his seminal work on common property resources, H. Scott Gordon proposed that in a fishery with multiple grounds, effort would be distributed such that profit rates would be equal among them. Gordon's model relies on implicit assumptions that are inaccurate and lead to false conclusions in many cases. In this paper, we present an empirically estimated model of fishery and location choice for large trawlers in New England using a random-utility framework with a nested-logit model specification. We use the model to test the validity of a behavioral model developed from ethnographic interviews with skippers.
