The objective of this paper was to examine the cost efficiency of corn and soybean pro-duction for typical farms involved in the cash crop agri benchmark network using data for the period 2013 to 2017. Average cost efficiency for the typical farms in the network that produced corn, soybeans, and both corn and soybeans was 0.749, 0.774, and 0.939, respectively. Inefficiency was a greater problem for the farms producing corn than for the other farm types examined. Inefficient farms tended to overutilize direct, operating, and overhead inputs.
