Yield maps and GPS-based soil maps have been increasingly used in U.S. agriculture but little research has explored the economic relationship between mapping technologies and agricultural productivity. Research on this relationship is lacking, perhaps because maps are information inputs that do not directly enter the production function in a comparable way to conventional inputs. A stochastic frontier model was used to evaluate one potential avenue through which mapping technologies may influence productivity – technical efficiency. After controlling for farmers’ potentially endogenous choice of map technologies, adoption of yield maps has a positive influence on technical efficiency, and unexpectedly, adoption of soil maps has a negative influence on technical efficiency. Given that yield maps are a basic information input, this suggests that increased availability of some information or data-type inputs, by themselves, can have indirect production benefits to farmers.
