In Costa Rica, the rice industry took the traditional route of lobbying for protection. Though there was no market failure to remedy, the government obliged, introducing high import tariffs and subsidies for powerful local growers; as a result, productivity declined.
对比一下哥斯达黎加和阿根廷的部门政策。在哥斯达黎加，水稻产业采用了传统政治游说手段来寻求自保。虽然不存在需要弥补的市场失灵，但是政府却就范于该产业，强行引入高进口关税并补贴本地大种植者；结果水稻生产力一路下滑。
