Separability in State‐Level Agricultural Technology

Abstract

Abstract A nonparametric analysis of separability in agricultural production technology was conducted using state‐level data. Both deterministic (exhaustive search) and stochastic (measurement error) tests were performed. The empirical findings do not rule out a reasonable amount of data aggregation, both among inputs and among outputs. The nature and extent of the justified aggregation varies widely among states, supporting the notion that the structure of agricultural production varies in important ways across states.
