Structure of south central agricultural production

Using a dual economic specification of a multi- product technology, the structure of agricultural production was tested for five South Central states purpose. (Texas, Oklahoma, Arkansas, Mississippi, and Louisiana). A comprehensive set of output supplies and input demands comprised the estimation equations in each state. Evidence of non-joint in a subset of commodities was detected in four of five states. Several commodities also satisfied sufficient conditions for consistent aggregation. However, the specific outputs satisfying each structural property varied by state. Sufficient conditions for consistent geographic aggregation across the states were not satisfied. These results provide empirical guidance and important cautions for legitimately simplifying state-level model specifications of southern agricultural production.
