A Survey of Technological Structure of Wheat Production by using Panel Data

The purpose of this study is to define the technological structure and to define relationships among different inputs in irrigated wheat production. A duality approach is used to estimate cost share equations, using panel data that is blend of cross-section and time series data in 28 provinces in a period of 10 years. By the use of estimated parameters obtained from model estimation, Allen elasticity substitution and price demand elasticity were computed. All the assumptions of the duality approach are fulfilled by the estimation procedure and the restrictions of theory are not rejected by the data.
