An almost ideal demand system was estimated to examine the impacts of low carbohydrate information on the demand of vegetables in the United States. Analysis was extended to examine the performance of alternative carbohydrate information indices. Results show significant impacts of low...

Developing a dairy supply model assuming deterministic trend and seasonality a priori could lead to model misspecification. A structural time series methodology was used to examine the role of stochastic trend and seasonality in a dairy supply response model using quarterly time series data....

Swine supply response was analyzed using a structural time series model (STSM) with both seasonal and yearly effects introduced stochastically. Swine production is divided into four production phases. Parameters of each phase were then estimated using a structural time series model....
