我们建立了具有目标和副渔获两种个体配额的渔场中捕捞者的时间参与行为模型。根据渔业的时变特征(如渔获率、价格和副渔获率)和外部机会(如其他渔业),收割机作出参与决定。由于配额作为跨期预算约束,在个体配额方案下,采收者的问题是季节性动态的。我们构建了一个理论模型来描述个人配额的影子值如何在采集者的决策中发挥作用,并提出了一个捕捉季节性配额使用动态效应的实证模型。我们的研究发现了动态副渔获物避免存在的支持:捕捞者利用配额分配提供的安全性来减少在高副渔获物期间的捕捞。我们的政策模拟表明,由于配额使用的时间变化,提前开放季节可以减少副渔获量,同时保持主要目标渔获量。
We model harvesters’ temporal participation behavior in a fishery with individual quotas for both a target and bycatch species. Harvesters make participation decisions given time-varying characteristics of the fishery (e.g., catch rates, price, and bycatch rates) and outside opportunities (e.g., other fisheries). A harvester’s problem is seasonally dynamic under the individual quota scheme because quota acts as an intertemporal budget constraint. We construct a theoretical model to describe how the shadow value of individual quota plays a role in a harvester’s decision and propose an empirical model that captures the dynamic effect of the seasonal quota usage. Our study finds support for the existence of dynamic bycatch avoidance: harvesters use the security provided by quota allocations to reduce harvesting around periods of high bycatch. Our policy simulation demonstrates that opening the season earlier could reduce bycatch while the main target catch is maintained due to temporal shift of quota usage.
