Economic theory provides little guidance for selecting a numeraire in estimating dual function profit functions. In this study, we examine the choice of numeraire price (equation) for profit function models of Iowa agriculture. The choice of numeraire is evaluated by forecasting accuracy and...

Ever since 1927, when Al Jolson spoke in the first “talkie” film The Jazz Singer, there had been little doubt that sound added a valuable perceptual dimension to visual media. However, despite the advances of over 80 years, and the complete integration of sound and vision that has occurred...

Should econometricians always incorporate economic theory in their models or only when unrestricted estimators are found to violate an inviolable theory? Using Monte Carlo experiments, we find that econometricians should use economic theory to the fullest extent possible. To paraphrase Leamer's...

A structural time series methodology was used to examine the role of stochastic trend and seasonality in dairy supply response model. In our analysis, the dairy supply model with stochastic seasonality and deterministic trend performs best in terms of diagnostic tests, goodness-of-fit measures,...

We estimate a dynamic version of an almost ideal demand system (AIDS) model for U.S.A. imports of fresh tropical fruits: bananas, pineapples, avocadoes, papayas, mangoes/guavas, grapes and other fresh fruit imports. An error correction model specification is justified after unit root and...

This research examined the relationship between food insecurity, the National School Lunch Program, and academic achievement in Georgia public schools. A multilevel Poisson regression model was used to examine these relationships. Findings confirm a strong inverse relationship between poverty,...
