Surplus accounting is a method for evaluating trends in how a firm's productivity factors (intermediate inputs, capital, land, labour) are performing and how the productivity gains are redistributed between agents in the economy. Here the surplus accounting method was applied on a database of 164 Charolais-area suckler cattle farms running from 1980 to 2015. Over this 36-year period - with differences per sub-period - the cumulative productivity surplus (PS) increased at a low rate of +0.17%/year (i.e. cumulative volume of outputs produced increased slightly more than cumulative volume of inputs used). This timid increase in PS is linked to the constant expansion in labour productivity whereas other factor productivities have shrunk. The observable period-wide macrotrends are that commercial farm businesses struggle to protect their revenues, we also observe a slight fall in input prices, land rent and financing costs, and a huge climb in direct support-policy payments. The bulk of the cumulative economic surplus has been captured downstream - 64% downstream of the cattle value chain as a drop in prices, and 22% downstream of other value chains (chiefly cereals). It emerges that the productivity gains in beef cattle farming mostly benefit the downstream value chain (packers-processors, distributors and consumers), whereas it is mainly government money backing this drop in prices of agricultural output. Here we see the principal of the 1992 'MacSharry' reform at work, with a transfer from the taxpayer through direct support-policy payments through to the consumer via lower prices. The simple fact that farmers' incomes are stagnating is a clear indication that they are net losers in this distribution of productivity gains, despite the improvement in labour factor productivity.
剩余会计是一种评估企业生产力要素(中间投入、资本、土地、劳动力)表现趋势以及经济中各主体之间生产力收益如何再分配的方法。在这里,剩余会计方法应用于 1980 年至 2015 年的 164 个夏洛莱地区奶牛养殖场的数据库。在这 36 年期间——每个子期间都存在差异——累积生产力剩余(PS)以每年+0.17%的低速度增长(即累计产出量的增加略高于累计投入量的增加)。PS 的这种缓慢增长与劳动力生产力的持续扩张有关,而其他要素生产力则在下降。可以观察到整个时期的宏观趋势是,商业农场企业难以保护其收入,我们还观察到投入价格、土地租金和融资成本略有下降,以及直接支持政策支付额的大幅上升。大部分累积经济剩余都在下游被捕获——作为价格下降,在牛价值链的下游捕获了 64%,在其他价值链(主要是谷物)的下游捕获了 22%。这表明,肉牛养殖的生产力收益主要使下游价值链受益(包装商-加工商、分销商和消费者),而价格下降主要是政府资金支持。在这里,我们看到了 1992 年“MacSharry”改革的原则在起作用,纳税人的资金通过直接支持政策支付转移到消费者,通过降低价格。农民收入停滞不前的事实清楚地表明,尽管劳动力要素生产力有所提高,他们在这种生产力收益分配中是净输家。
