Wheat regression models that account for the effect of weather are developed to forecast wheat yield and quality. Spatial lag effects are included. Wheat yield, protein, and test weight level are strongly influenced by weather variables. The forecasting power of the yield and protein models was...

This article analyzes the dynamic relationships among weekly prices of price byproducts, long gram rice, and corn, using causality tests and dynamic multipliers The authors use forecasts to evaluate the time series model rice byproducts prices may be influenced more by shifts 10 demand than 10...

This paper develops a measure of efficiency when data have been aggregated. Unlike the most commonly used efficiency measures, our estimator handles the heteroskedasticity created by aggregation appropriately. Our estimator is compared to estimators currently used to measure school efficiency....

Large families in rural areas causes pressure on natural resources, an upsurge of inter-community conflicts. Anecdotal evidence suggests that one reason for large families is the value of children as a source of labor.This research determines the marginal change in household productivity with...

Obtaining estimates of pesticides productivity is an economic response to the growing public concern about the steady increase of pesticide use in the United States. This type of research indicates the cost of limiting pesticide use in terms of foregone output. Pervious empirical studies give a...

A new stochastic process is introduced where permanent changes occur following a Poisson jump process and temporary changes occur following a normal distribution. The model is estimated using hard wheat basis data and is used to explain why the optimal length of moving average to forecast basis...

Crop producers are increasingly interested in reducing nitrogen use without sacrificing yield. Technology is available for precise application at the sub-field level, but adoption has been sluggish. This paper estimates the relative profitability of a field level annual predictor of mid-season N...

The incentives researchers face depend directly upon what we as a profession value. The impacts of research can be either disciplinary by adding to economic knowledge or real world by being useful to economic agents. Various measures of research impact such as publications, citations, and...

Many previous studies provide pricing models of options on futures spreads. However, none of them fully reflect the economic reality that spreads can stay near full carry for long periods of time. We suggest a new option pricing model that assumes that convenience yield follows arithmetic...

If switchgrass harvest is delayed until after senescence, some nutrients will translocate to the plant’s crown and roots. Biomass yield and fertilizer requirements depend on harvest date. The objective is to determine switchgrass biomass yield, nutrient concentration in biomass, fertilizer...
