This article investigates the possibilities of including policy choices directly into a sector model that simulates an economic equilibrium It uses a mathematical programming framework because these models have wide applicability in agricultural sector analysis The objective function is...

This article demonstrates that when a second product is introduced into the traditional single-product, partial equilibrium model, the predictions of the impact of a tariff on prices are no longer determinate In contrast to the traditional single-product partial equilibrium framework in a...

The traditional model used to analyze trade Issues suggests that an export subsidy on agricultural products IS an irrational policy choice However, export subsidies are common in world agricultural trade By relaxing the assumptions of the traditional model, researchers can develop several...

The costs of obtaining a given level of accuracy in estimating yields of tree fruit might be lowered by the use of photographs or supplemental information on fruiting potential. A small-scale experiment of this sort is described for peaches and apples. A procedure for evaluating the relative...

A ban on toxaphene use In control of the cotton budworm bollworm would Increase the average price of cotton 8S well as Its Price instability It would decrease the level and Increase the variability of cotton Yield and production Such 8 ban would also decrease the expected value but not the...

Preharvest production forecasts can be combined with contemporaneous price quotations for futures contracts to estimate demand equations, but the methodology has limitations for estimating structural coefficients An application using data for corn highlights the difficulties The methodology,...

The demand for U.S. feed grain is estimated using a six-equation simultaneous model. Four different utilizations of feed grain and feed grain price as well as the number of animal units fed are estimated. The reduced form of the model is used to provide forecasts of the endogenous variables for...

Understanding the dynamic programming algorithms used In the optimal grain storage literature IS a prerequisite to understanding the findings of this literature This article Introduces these dynamic programming algorithms by examining several In terms of their underlying economic behavior These...

Changes in the distribution of an agricultural commodity among quality classes may affect the total revenue obtained from a given quantity of product. Growers and marketing firms need to consider the best mix of qualities as well as the best level of output. This paper describes an approach to...
