Online surveys have emerged as low-cost data collection approach in empirical researches; however, the validity of data remains questionable. Therefore, we employed a stochastic frontier estimation method to calibrate online recreational expenditure. Study results suggested the presence of...

We used poisson and negative binomial models to estimate future demand of recreation trips to a closed site using internet and intercept surveys. Parameter estimates were validated using 1,000 bootstrap replications. Result indicated a significant negative impact of travel time and positive...

Poultry litter can be used as plant nutrients or cattle feed. Both of these alternatives may increase phosphorus concentration in the nearby watershed. Use of phosphorus consistent litter application rule in nutrient management combined with permit system has potential to curtail the over...

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...

One of the challenges in estimating economic impacts of recreational activity and natural resource use is collecting survey data when the underlying population is not perfectly known. We combine bootstrapping techniques with input output analysis to estimate impacts from recreational activity at...

Poultry litter is a byproduct of poultry production which has potential to cause water quality problem if it is not applied properly on land as a nutrient source. Using survey information available from Louisiana broiler producers, we found that broiler litter is not cost‐effective to...

The stochastic impact of the "climatic fluctuation effect" is introduced in the traditional determinant timber growth model and optimal harvesting strategies are derived under different stochastic "climatic fluctuation effect" patterns. Results show that properties of different patterns...

This study applies the fixed allocatable input model to test the effect of water price on the multiple production decision in Georgia, U.S. The limited dependent variable models are applied and intensive data are analyzed in this study to estimate the decision for crop choice, land allocation,...

We estimate the contract prices that must be paid to grow cellulosic energy crops, and the costs of harvesting and transporting those crops in the Beaumont, TX area. Results indicate that the delivered price would range between $54 and $101 per ton of dry matter depending on the specific crop.
