Tilapia is a fast-growing fish that has huge potential for production in Bangladesh. Despite the impressive growth of the industry, production is highly volatile across farms and locations. Both output risk and/or inefficiency will lead to variation in production. While several studies have focused on either technical efficiency or risk, few studies have been conducted on the combined effect of production risk and technical inefficiency. By employing a stochastic production frontier model with flexible risk specification on cross-sectional data from 339 sample farms, this article quantifies the production variability of tilapia farming from two main possible sources: production risk and technical inefficiency. Furthermore, our analyses identify the factors influencing risk and inefficiency. Knowing the source of the variation is vital for farmers and policy-makers in choosing the right strategy to reduce production variation. Our main findings are that significant production risk and technical inefficiency exist in tilapia farming.

孟加拉国罗非鱼养殖的生产风险和技术效率

罗非鱼是一种生长迅速的鱼类，在孟加拉国具有巨大的生产潜力。尽管该行业取得了令人瞩目的增长，但不同农场和地点的生产波动很大。产出风险和/或效率低下都会导致生产变化。虽然有几项研究侧重于技术效率或风险，但很少有关于生产风险和技术低效率的综合影响的研究。通过对来自 339 个样本养殖场的横截面数据采用具有灵活风险规范的随机生产前沿模型，本文从两个主要可能的来源量化了罗非鱼养殖的生产变异性：生产风险和技术效率低下。此外，我们的分析确定了影响风险和低效率的因素。了解变异的来源对于农民和决策者选择正确的策略来减少生产变异至关重要。我们的主要发现是罗非鱼养殖存在重大的生产风险和技术效率低下。
