What Is The Value Of Ethanol To Nebraska Corn Producers?, Austin Harthoorn
What Is The Value Of Ethanol To Nebraska Corn Producers?, Austin Harthoorn
Department of Agricultural Economics: Dissertations, Theses, and Student Research
In this thesis, we examine the role of local ethanol plants on net price received by Nebraskan corn growers, with net price comprised of the grain buyer’s bid onsite less the transportation cost incurred through delivery. As each farm operation is uniquely located between different sets of grain buyers, an ethanol plant impacts each grower’s net price to a different degree, depending on location. Exploring this, we use grain bid and transportation cost data based on actual ethanol plants, grain elevators, and sample farm locations in Nebraska, estimating the diversely located corn grower’s net prices received from surrounding grain buyers. …

Causal Forest Approach For Site-Specific Input Management Via On-Farm Precision Experimentation, Shunkei Kakimoto
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Estimating site-specific crop yield response to changes to input (e.g., seed, fertilizer) management is a critical step in making economically optimal site-specific input management recommendations. Past studies have attempted to estimate yield response functions using various Machine Learning (ML) methods, including the Random Forest (RF), Boosted Random Forest (BRF), and Convolutional Neural Network (CNN) methods. This study proposes use of the Causal Forest (CF) model, which is one of the emerging ML methods that comprise “Causal Machine Learning.” Unlike previous yield-prediction-oriented ML methods, CF focuses strictly on estimating heterogeneous treatment effects (changes in yields that result from changes in input …
