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...

Opinions differ among economists as to how effective statistical analyses using time series data can be in identifying factors affecting demand and in measuring their influences. Although this presentation may not materially modify these opinions, it should at least succeed in making even the...

Statisticians are constantly trying to make their methods more precise, not only because of their scientific interest but also to meet the ever-increasing load which modern society throws upon statistical measurement. A notable contribution has been made over the last dozen years by means of the...

Much has been written concerning the importance of risk and uncertainty on decision making. However, research results employing static theory are seldom modified by risk and uncertainty considerations to provide more realistic recommendations to farmers and others making decisions under...

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...

The United States Department of Agriculture is cooperating in an interagency study to plan for the future development and control of the water resources of the Potomac River Basin.' One assignment undertaken by the Farm Economics Research Division, Agricultural Research Service, is that of...

It 15 difficult to obtain c1osed-fonn solutions for input demand equations that are conducive to econometric estimation and policy analysis when the production function IS unknown Developments In the theory of duality facilitate obtaining such equations This article provides three examples of...
