Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Over the past decade, feeder cattle backgrounders in the Pacific Northwest have been subject to sharp price fluctuations for their output. The result has been variable profits and losses. This situation creates a need for management and marketing techniques which can provide Pacific Northwest cattle ranchers with protection against price risks while enhancing the profitability of their operations. Recent economic literature has shown hedging with futures contracts to be an effective tool for mitigating risk and/or increasing the net revenues of cattle producers in a number of regions of the United States. The objective of this research was to determine whether hedging with futures contracts could have increased the profitability of Pacific Northwest feeder cattle production while decreasing the effects of price volatiliy. To realize this objective, the economic performance of alternative hedging strategies were evaluated for several methods of feeder cattle backgrounding indigenous to the Pacific Northwest region. Four hedging strategies - routine, moving average, profit objective, and triangular probability distribution - were evaluated for hedging the output of four simulated production systems. The mean and standard deviation of annual net returns were computed for each hedging strategy to serve as measures of profitability and risk, respectively. The results of not hedging were also obtained to provide a basis for comparing alternative hedging programs. Sample t and F tests were conducted to determine whether there were statistically significant differences between the means and standard deviations of the unhedged and hedged positions. Dominant hedging strategies were then identified for each production system. Based on the results of the mean-variance analysis, it appears that the use of selective futures market hedging strategies would have provided greater and more stable levels of profit compared to the net incomes obtained without hedging. Sample t and F tests, using 80 and 90 percent levels of significance respectively, showed that hedging could have significantly decreased the variability of the producer's flow of income without significantly changing the operation's average profitability. Moving average, profit objective, and triangular probability distribution strategies were dominant, increased average profitability, and significantly lowered risk for at least one production system each. Overall, moving average strategies generated the highest mean profits with the greatest risk. Profit objective strategies generally resulted in lower mean profit than moving average strategies but with less risk. The risks and returns from hedging with triangular probability distribution strategies were usually between the moving average and profit objective procedures. Strategies which performed well in this study should also perform well in the future if conditions in the feeder cattle markets do not vary substantially from those of the previous decade. Thus, hedging with futures market contracts may provide the Pacific Northwest feeder cattle producers with protection against price risk and enhanced profitability.

Feedlot finishing of beef cattle in Southern Alberta involves income risk due to the variability of prices of feeders, feed and finished cattle. Several strategies are available to reduce this risk, including hedging of cattle on feed, participation in a Federal- Provincial government and producer established income stabilization program for finished cattle (National Tripartite Stabilization Plan) and diversification of production plans. This study evaluated the efficacy and interaction effects of these strategies in reducing net income variability in cattle feeding in Southern Alberta. Concerns that were addressed included: (1) whether participation in hedging or Stabilization would increase firm-level slaughter cattle output, (2) whether portfolio effects exist between production and marketing alternatives, (3) whether participation in Stabilization would reduce participation in hedging (4) whether hedging performance could be increased by hedging the Canadian dollar, and (5) whether privately supplied hedging versus publicly supplied Stabilization is better able to handle income risk in cattle feeding. The theory of decision making under uncertainty was reviewed to determine how to best incorporate the risk aspects of the feedlot, management problem. Expected Value-Variance (EV)and safety-first risk analyses were identified as frameworks for formulation of the feedlot management problem in a mathematical programming context. Using data from 1976-87, linear risk programming (MOTAD and Target MOTAD) models of the feedlot process were constructed to analyze the alternatives for reducing income risk. Results for the 1986-87 feeding year suggested that, at moderate levels of risk aversion, feedlot managers should maintain high levels of hedging of both live cattle and the Canadian dollar with moderate participation (25 percent of cattle on feed) in the Stabilization plan. Significant portfolio effects were present. Hedging, but not Stabilization, was found to increase firm-level output by increasing the average weight to which a group of cattle would be finished. Participation in Stabilization was found to reduce hedging participation by an average of 10 percent. Hedging of the Canadian dollar improved the performance of live cattle hedging. Whether hedging was better at reducing risk and maintaining income than Stabilization depended on the definition of risk.
