Essays On The Designs And Benefits Of Land Conservation Programs, Badri Khanal
Essays On The Designs And Benefits Of Land Conservation Programs, Badri Khanal
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This dissertation analyzes the policy designs and economic benefits of a land conservation practice called prairie strips. The first chapter investigates the impact of policy designs on individual household preferences. The study measures the value that Iowa residents place on the ecosystem services of prairie strips and determines if that value changes under different policy designs. The policy design treatment varies in who runs the program and who has enrollment priority. The willingness to pay (WTP) for ecosystem services is estimated using stated preferences from a choice experiment. Results indicate significant public support for expanding and funding the prairie strips …
Impacts Of Crop Insurance And Intra-Season Hedging On Long-Run Net Income Risk, Kara Zimmerman
Impacts Of Crop Insurance And Intra-Season Hedging On Long-Run Net Income Risk, Kara Zimmerman
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Each year producers must make risk management decisions early in the growing season when many variables are unknown. In this thesis we create an empirical model utilizing thirty years (1989-2018) of historical yield, cost, and daily price series data, to determine the optimal risk management strategy of crop insurance and an intra-season marketing plan that will both minimize net income risk and maximize average net income. The empirical model is taken a step further to include an out-of-sample year in order to test the robustness of empirical results to financially devastating events that have never been seen. We test the …
Economically Optimal Nitrogen Side-Dressing Based On Vegetation Indices From Satellite Images Through On-Farm Experiments, Qianqian Du
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Optimal N fertilizer rates for corn (Zea mays L.) vary substantially within and among fields, and by corn growth stages. Improving N side-dressing management can improve fertilizer use efficiency, farmers’ profitability, and the sustainability of crop production. The objective of this study is to introduce a framework along with a methodology that can find the site-specific economically optimal N rates (EONRs) within one field for a particular growing season. An on-farm experiment was conducted in the 2019 corn growing season. A base N rate was applied uniformly on the field. NDRE images from the Sentinel-2 satellite were observed during …
Essays On Agricultural Technology, Resource Allocation And The Value Of Information, Pedro Queiroz
Essays On Agricultural Technology, Resource Allocation And The Value Of Information, Pedro Queiroz
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This dissertation studied the adoption of agricultural technologies and the value of information for the allocation of resources in agriculture. Chapter 1 studied traditional (e.g., land and labor) and commercial (e.g., machinery and fertilizers) inputs in South American agriculture. Acemoglu’s directed technical change was used to estimate the process of induced innovation using deforestation as source of exogenous variation for the agricultural land supply. The results indicated that larger availability of land in intensive deforestation countries caused more land-complementary inputs (machinery) to be used relative to labor-complementary inputs (fertilizers). Technical change was biased towards land. Chapter 2 studied nitrogen fertilizer …
Determinants Of Discretionary Agricultural Policy Adoption:The Case Of The Livestock Friendly County Program In Nebraska, Cicely Batie
Determinants Of Discretionary Agricultural Policy Adoption:The Case Of The Livestock Friendly County Program In Nebraska, Cicely Batie
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This study analyzes the voluntary approach to agriculture promotion programs through the lens of the Nebraska Livestock Friendly County (LFC) Program. In 2003, the Nebraska Department of Agriculture (NDA) launched the LFC program to bolster the livestock sector in participating counties. The program is unique because of its voluntary nature and targeted agricultural promotion efforts. The NDA designates counties as “Livestock Friendly,” and assists them in streamlining approval processes for livestock feeding operations. This thesis examines why a program like LFC is necessary, the patterns of its adoption across Nebraska, and finally, its impact on the livestock sector of participating …
