This study estimated net irrigation benefits from the proposed Cable Mountain Reservoir (CMR) on the North Fork of the Red River in Southwestern Oklahoma. Part of the benefits from the CMR might come from replacing the largely depleted groundwater in the Tillman Terrace area (TTA) of western...

Cotton has been a success story in West Africa since independence swept the region in the early 1960's. Today, however, 'white gold' is struggling to maintain its allure. Recent declines in world cotton markets have created a crisis in the region's cotton sectors. Cotton is still being produced...

Low-input farming practices in many parts of the developing world have pushed cultivation onto marginal lands. Sustainability of already fragile ecosystems is threatened. Farmers place a high priority on satisfying subsistence food needs with on-farm production. Population pressure is high...

A need in Sahelian agriculture is to transform from traditional farming to more modern systems. This paper presents a safety-first type of risk programming model, using complementary programming, to assess the impacts of new agricultural technology. Model results indicate that some new...

Economic theory is replete with causal hypotheses that are scarcely tested because economists are generally constrained to work with observational data. This article describes the use of causal inference methods for testing a hypothesis that one random variable causes another. Contingent on a...

To date, mixed demand systems have been all but ignored in empirical work. A possible reason for the scarcity of such applications is that one needs to know a priori which prices and quantities are endogenous in the mixed demand system. By using a directed acyclical graph (DAG), causal...

We describe a means of rejecting a null hypothesis concerning observed, but not deliberately manipulated, variables of the form H0: A -/- B in favor of an alternative hypothesis HA: A -- B, even given the possibility of causally related unobserved variables. Rejection of such an H0 relies on the...

Consumer demand analysis attracts considerable attention. It remains an open question, however, whether estimating demand with aggregate data is reliable when disaggregate store-level data is given. Demand models may produce biased results when applied to data aggregated across stores with...

Recent studies and reports suggest that foreign aid/intervention has been somewhat futile in eradicating conflict. In this study, we develop a simultaneous donor/recipient model of foreign aid and terrorism. Thereafter, we extend our theoretical propositions through a machine learning algorithm...

This study uses unrestricted vector autoregression method and historical decomposition with directed acyclic graphs to quantity the impacts of the foot and mouth disease outbreak on the Brazilian meat market for different levels of the industry (export, wholesale and farm). The imposition of an...
