The Firm's Management in Production: Management, Firm, and Time Effects in an Indian Ocean Tuna Fishery
利用追踪多家企业多位管理者的面板数据，通过三向固定效应模型分离企业效应和时间效应，研究企业管理对金枪鱼捕捞生产的影响，发现船长的经验与任期对产出无显著作用。
Exploiting variability in the managerial dimension, this paper presents firm management through firm and time effects in a production function that uses a three‐way fixed effect model and a unique panel dataset that tracks multiple managers for each firm from 1980–2007. We allow for time‐varying firm management through learning. The model is applied to the French purse‐seine fleet harvesting tuna in the Indian Ocean. We find that skippers' learning‐by‐doing as measured by experience and job tenure plays no significant role, meaning that managerial ability is time‐invariant.
