Drivers of Profit Inefficiency in Iowa Crop Production


  • Sawadgo, Wendiam P. M.
  • Plastina, Alejandro


In this paper, we use data envelopment analysis and a panel of Iowa farms to evaluate profit inefficiency in corn and soybean production. We find that farms have, on average, profit inefficiency scores of 89.4% in combined corn and soybean production, suggesting that profit could be increased by 89.4% if farms eliminated technical and allocative inefficiencies. Overall, profit efficiency improved from 2011 to 2018, a period generally characterized by decreasing farm net worth. Moreover, while factors such as farm size and operator age affect technical inefficiency, these variables do not have a significant effect on profit inefficiency, while farms’ net worth per acre and crop insurance indemnity payments positively affect profit inefficiency. Land tenure does not have a significant effect on technical or profit inefficiency.
