Item Price relationships in the U.S. nitrogen fertilizer industry(Montana State University - Bozeman, College of Agriculture, 2018) Gumbley, Thomas J.; Chairperson, Graduate Committee: Anton BekkermanThis study estimates the price dynamics in the U.S. nitrogen fertilizer industry, measures information flow efficiency in spatially separated fertilizer markets, and measures to what extent structural changes in corn and natural gas markets may have altered these price dynamics and information flow relationships. A vector error correction model is used to measure the short-run and long-run relationships between nitrogen fertilizer markets, natural gas markets, and corn markets. The results show that price information flows from the central market of New Orleans to inland regional markets. The efficiency of this information flow increased in the period after the Renewable Fuel Standards increased the demand for corn.Item An empirical comparison of alternative functional forms of systems of consumer demand equations(Montana State University - Bozeman, College of Agriculture, 1984) Roheim, Cathy AnneItem A dynamic price and supply model of the U.S. pork industry(Montana State University - Bozeman, College of Agriculture, 1984) Black, Cecil DeeItem Opportunities and outcomes in the U.S. labor market, 1967-1981(Montana State University - Bozeman, College of Agriculture, 1984) Romeo, Charles JohnItem Loan refinancing decision model(Montana State University - Bozeman, College of Agriculture, 1984) Pidruchney, PatriciaItem A study of the aggregate United States labor supply function(Montana State University - Bozeman, College of Agriculture, 1984) Oster, Jeanette MarieItem An economic analysis of the 160 acre limitation in District One of the Lower Yellowstone Irrigation Project with policy implications(Montana State University - Bozeman, College of Agriculture, 1980) Haynes, George WalserItem Effects of sample size on MOTAD and Target MOTAD solutions(Montana State University - Bozeman, College of Agriculture, 1984) Jones, Clark Thomas; Co-chairs, Graduate Committee: Daniel Dunn and Myles WattsThis study examines the effects of sample size on MOTAD and Target MOTAD solutions. Data sets based on historical observations are generated with a multi-variate normal random deviate generator. A representative Montana dry-land grain farm supplied the historical data. Ten data sets of each sample size (10, 20, 30, 40, 50, and 70 observations per activity) are generated and input into both of the linear risk models. All of the MOTAD models arrived at feasible solutions. Considerable instability was observed in the objective function values and basis activity levels for even the largest samples (at the lower deviation levels). However, as sample size increased the MOTAD results tended to be more stable. Several of the Target MOTAD models were infeasible due to the specified deviation and/or target income levels. In the feasible Target MOTAD models, stability of the objective function values and basis activity levels was noted when sample sizes were 30 observations or larger. Feasible Target MOTAD models resulted in considerably larger objective function values than comparable MOTAD models. The feasibility problems of the Target MOTAD specification serve to illustrate theoretical problems of the traditional MOTAD model.Item Simulation via time-partitioned linear programming : a ground and surface water allocation model for the Gallatin Valley of Montana(Montana State University - Bozeman, College of Agriculture, 1968) Boyd, Donald W.Item The effects of taxes and inflation on the composition of inputs to agriculture(Montana State University - Bozeman, College of Agriculture, 1981) Hart, Douglas Roger
