Specification of the variance-covariance matrix holds continuing interest for agricultural economists considering risk programming applications. This research examines alternative expected value-variance (E-V) frontiers constructed using contemporaneous and non-contemporaneous data and two...

While agricultural land preservation programs seek to maximize number of acres, to preserve productive farms, to preserve contiguous farms, and to preserve threatened farms, they are often evaluated solely on the number of acres preserved. Using a Farrell efficiency analysis, preserved parcels...

A model with omitted resource constraints is suggested as an alternative to a risk aversion model for explaining economic behavior. This paper uses two standard mathematical programming models to further explore this issue. One model is a standard profit maximization linear programming model and...
