本文阐述了通过农业政策干预广泛支持养牛业与牛的负回报之间的明显悖论，正如最近的著作所强调的那样。使用印度安得拉邦有代表性的面板数据集，我们探索了养牛的平均和边际盈利能力。我们发现，养牛很可能会产生正回报，但大多数家庭似乎都在无利可图的水平上经营。我们的结果表明，养牛业与生产技术中相当大的非凸性有关，大量的规模经济，以及购买高生产率动物的高额前期费用，可能会使较贫穷的家庭陷入低生产率资产水平。
This paper addresses the apparent paradox between widespread support of cattle farming through agricultural policy interventions and negative returns to cattle, as stressed in recent works. Using a representative panel data set for Andhra Pradesh, India, we explore the average and marginal profitability of holding cattle. We find that cattle farming might well generate positive returns, but most households seem to operate at unprofitable levels. Our results suggest that cattle farming is associated with sizable nonconvexities in the production technology and that substantial economies of scale, as well as high up-front expenses of acquiring high-productivity animals, might trap poorer households in low-productivity asset levels.
