Abstract: Annual data for forty-eight states are used to account for changes in the composition of input and output aggregates over space and time, and thereby to obtain new evidence on changes in inputs, outputs, and productivity in U.S. agriculture. The measures change significantly when we use state-specific rather than national prices and when we allow for changes in the composition of the aggregates, especially of labor and capital inputs. We compare our estimates and those reported by Ball et al. (American Journal of Agricultural Economics 81(1999):164–79). The national estimates are similar but substantial differences are found in state-level productivity growth. Copyright 2003, Oxford University Press.
