Slippage rates for corn and wheat are estimated using a simultaneous system explaining per-acre yields, input usage, technical change, and levels of participation in government programs. Soybeans are included due to cross-compliance requirements and because they substitute for corn in...

An elusive restriction maintained in earlier CET supply models with three or more products is shown to result in a potentially serious misspecification. Its impact on empirical estimates is found to be substantial, and an alternative formulation is presented which overcomes the problem while...

Conceptual problems in model specification of beef supply response studies are investigated and a simultaneous equation model is formulated to estimate annual U.S. carcass supply, demand, and inventories of beef. Three basic issues are addressed: (a) disaggregation, (b) simultaneity, and (c)...

Based on a theoretical formulation of land price formation as an economic rent to a fixed input, a single equation econometric model is specified and estimated to explain land prices in five Iowa crop reporting districts. It identifies the influence of farm prices, inflationary pressures, and...

A restricted profit function model of California agriculture is specified and estimated subject to prior information provided by economic theory. Symmetry, homogeneity, and convexity of the profit function are maintained in the estimation. Parameter estimates and elasticities are presented for...

The constant elasticity of transformation (CET) linear supply model is adapted and evaluated in this analysis of short-run supply response of six Texas field crops. Cross-product supply elasticities are estimated and direct supply elasticities are derived. The sensitivity of estimated parameters...

Some implications of theory are easily maintained in econometric estimation, but computational costs of maintaining curvature properties (sufficient for existence of an optimal solution) have often proved prohibitive. They also have been violated frequently by unrestricted econometric estimates....
