This study conducts an investigation on the application of classical unit-root tests using parametric tests (the augmented Dickey-Fuller, 1979 – ADF), and nonparametric tests (Phillips and Perron, 1988—PP) to corn and soybean yields in the Delta states using county-level data from 1961 to...

This study examines the role of price competitiveness and foreign activity in Ghana’s export performance. Using an augmented VAR model in conjunction with modified Wald tests, causal relationships are tested between real effective exchange rates, foreign GDP and both total and agricultural...

Peanut and corn are two major crops in the tri-state area of the Southeast US, an area encompassing North Florida, Southwest Georgia, and Southeast Alabama. Sharecroppers in this region apply higher amount of input in crop production than the average farmers. We analyzed the behavior of...

Rotational grazing has been promoted as a best management practice with environmental benefits and associated higher revenue. Its adoption rate has been relatively low. This study investigates the role of uncertainty in the adoption of rotational grazing with a cost-share by cattle producers....

We studied transboundary ground water management problems in the presence of hydraulic fracturing (fracking). We found that the presence of risk suggests a need to exercise caution in fracking. We also found that a cooperative outcome implies the decrease in fracking and the increase in steady...
