The three essays of this dissertation consider aspects of agricultural economics that are relevant to current agricultural policies, more specifically agricultural conservation programs and federal crop insurance programs in the United States. Econometric techniques, some of which are not standard in the literature, have been employed to provide additional insight into risks associated with crop production. Chapter 1 examines the impact of planting cover crops on the risk of a failure to plant a crop (i.e., the so-called prevented planting losses). Using a novel data set that combines satellitebased cover crop information and county-level crop insurance data in the US Midwest, we find evidence that counties with higher cover crop adoption rates tend to have lower levels of crop insurance losses due to prevented planting. In addition, the resulting reduction in prevented planting risk also becomes larger with longer-term multi-year cover crop use. These results support two notions of cover crop adoption: (1) cover crops improve soil conditions such that the likelihood and magnitude of prevented planting losses decrease, (2) the benefits of cover crops accumulate over time. The study posits that the ability of cover crops to deal with excess moisture (i.e., through better water absorption and improved water infiltration in the soil) is the main factor in its ability to reduce prevented planting losses.Chapter 2 builds crop yield risk modeling (four-directional simultaneous autoregressive model, FDSAR) to investigate how crop yield distribution varies in direction as well as distance. To accommodate spatial dependence that varies by direction, a new class of spatial models is developed using the spatial proximity matrix which different weights are assigned to neighbors in different directions. By accounting for the spatial anisotropy, the newly proposed model generalizes the usual SAR model that gives different weights to all directions. Finally, the method is applied to a county-level data set on corn yield risks in the Corn Belt from 1951 to 2019 in the United States. These findings show that spatial dependence of corn yield risks varies by direction. These findings imply that it may be an opportune time to revisit actuarially fair crop insurance rates and redesign reinsurance contracts between spatially correlated regions.Chapter 3 investigates the linkages between agriculture production and the incidence and nature of foodborne illnesses. By constructing county-level data by combining Centers for Disease Control and Prevention foodborne data, Bureau of Economic Analysis farm income and expense data, county health data, and Bureau of Labor Statistics food expenditure data, the findings of this study indicate that there is a significant correlation between food production and processing activity and risks associated with foodborne outbreaks. Intensive livestock farming appears to be particularly relevant to the risks of foodborne illnesses. Such production practices may weaken the immune system of farmers and neighboring residents who may be more likely to get ill from foodborne illnesses. Compared to agricultural producers, the food processing sector maintains relatively higher standards for hygiene which leads to relatively lower risks of foodborne illness. The results of this analysis have implications for assessing food safety risks. An important policy implication from the main findings is that there should be information dissemination efforts that impart knowledge to stakeholders about "the importance of occupational hygiene". This effort can enhance awareness and understanding of the benefit and likely encourage agricultural stakeholders to improve hygienic environments in their workplace.
