英文文献：Net Farm Income, Market Prices and Agricultural Productivity Growth in the United States-美国的农业净收入、市场价格和农业生产率增长
英文文献作者：Cahill, Sean A.
英文文献摘要：
If the claimants of net farm income are operators and unpaid family members, net farm income can be expressed as a real implicit wage per hour of work. Bennet indicators are used to decompose changes in the real implicit wage into input and output price change components and partial factor productivity growth (PFPG). PFPG is the difference between output growth and the growth of all inputs but operator and unpaid family labor. Data from the ERS production account for U.S. agriculture for 1948-2002 are used. The results show that, on average, positive PFPG was either partially or fully offset by the output and input price components. These results suggest that the accepted wisdom namely that agricultural productivity growth is key to the sector's prosperity has not taken into account the effect of output and input market price changes that happen at the same time.
如果农场净收入的索赔人是经营者和无薪家庭成员，农场净收入可以表示为每小时工作的实际隐性工资。本奈特指标将实际隐含工资的变化分解为投入产出价格变化组成部分和部分要素生产率增长(PFPG)。PFPG是产量增长与除经营者和无报酬家庭劳动以外的所有投入增长之间的差值。使用了1948-2002年ERS生产账户的美国农业数据。结果表明，平均而言，正向PFPG部分或全部被产出和投入价格组成部分抵消。这些结果表明，公认的观点——即农业生产率增长是该行业繁荣的关键——没有考虑到同时发生的产出和投入市场价格变化的影响。
