    Examination of North Dakota's Production, Cost, and Profit Functions: A Quantile Regression Analysis
    (North Dakota State University, 2008) Marroquin, Jacklin Beatriz
    This thesis estimates the production, cost, and profit functions for North Dakota agriculture using state-level input-output quantity and price data for the period 1960-2004. A Cobb-Douglas functional form with Hick-neutral technology change is used to measure the contribution of capital, land, labor, materials, energy, and chemical inputs quantities and output quantity using the primal production function; contribution of capital quantity, land quantity, output quantity, labor price, materials price, energy price, and chemical price to cost using the dual restricted cost function; and the contribution of capital quantity, land quantity, labor price, materials price, energy price, chemical price, output price to profit using the dual restricted profit function. In contrast to previous studies, quantile regression is used to explore the linear or nonlinear relationship between the independent and dependent variable by estimating parameter coefficients at each quantile using time-series data. Empirical findings suggest the cost function is the best model to examine the relationship between input prices, output quantity and cost using quantile regression for North Dakota agriculture, Further, the quantile regression suggests a linear and non-linear relationship between cost and certain independent variables.

    Impact of Climate Change and Weather Variability on North Dakota Agriculture
    (North Dakota State University, 2008) Mayom, Chol Permina
    This study used county-level yields and panel data (1950-2006) to explain the Impact of climate change and weather variability on North Dakota agriculture by estimating the effect of variation in temperature and precipitation on the yields of four major crops: com, durum, soybeans and wheat. In addition to yields, the study examined Impacts of climate change on crop gross revenues per acre for all 53 counties in North Dakota. An econometric model was developed to infer statistical relationships between weather variability and crop yields. Fixed and random effects models were employed to estimate the impacts of climate variables (temperature and precipitation) on crop yields. The Hausman test statistics was applied to test the preferred panel estimation approach: fixed versus random effects. Using mean values of precipitation and degree days for all counties, we calculated percentage changes in estimated crop yields for six climate change scenarios. The historical price data for the four crops (com, soybeans, spring wheat and durum) were used to generate per acre gross returns under the six weather-change scenarios in order to provide preliminary evidence about the effects of precipitation and temperature changes on farmer returns for the four crops.

    Impact of Federal Crop Insurance on North Dakota Agriculture Production Efficiency
    (North Dakota State University, 2017) Breker, Matthew John
    This study examines the impact of three major policy shifts in federal crop insurance on North Dakota agriculture production efficiency. An empirical application of 53 counties in North Dakota from 1980 to 2014 indicates that “with crop insurance”, the technical efficiency of agriculture is higher as compared to “without crop insurance”. This finding implies that producers are utilizing their input resources more effectively and are increasing the use of technology efficiently in their operations with crop insurance. The results are important to policy makers as it proves that with government support, the federal crop insurance program is not only mitigating risk for producers but also allowing producers to use resources efficiently; the program is ensuring producers will continue to lead the world as low-cost producers of food, fiber, and fuel for the American public.

    Time-Varying Estimation of Crop Insurance Program in Altering North Dakota Farm Economic Structure
    (North Dakota State University, 2008) Chow-Coleman, Jane Amy
    This study examines how federal farm policies, specifically crop Insurance, have affected the farm economic structure of North Dakota's agriculture sector. The system of derived input demand equations is estimated to quantify the changes in North Dakota farmers' input use when they purchase crop insurance. Further, the cumulative rolling regression technique is applied to capture the varying effects of the farm policies over time. Empirical results from the system of input demand functions indicate that there is no moral hazard since North Dakota farmers will increase fertilizer and pesticide use in the presence of crop insurance. Results also indicate that farmers in this state will not increase the use of land.
