Resumen
Descripción
We investigate the existence of an inverse relationship (IR) between farm size and technical efficiency in Philippine brackishwater pond aquaculture. The study is
motivated by the exemption of fish ponds from the Comprehensive Agrarian Reform
Laws and suggestions in the literature of inefficient management of fish farms. The
analysis of technical efficiency is based on the estimation of a multi-product ray production function estimated in a stochastic frontier framework. There is some evidence of an IR but of only limited strength. Hence, it is unlikely that agrarian reform is the key to unlocking the productive potential of brackishwater aquaculture in the Philippines.
