    SIMULATION OF HARVESTING ASPARAGUS: MECHANICAL VS MANUAL

    Asparagus harvesting methods and strategies have remained unchanged since inception in Washington. A bioeconomic model was developed to determine the profit optimizing frequency of harvesting for manual and mechanical harvesting techniques. The mechanical harvester is economically viable if the harvester cuts 72.3 percent and 73.55 percent of what a hand crew would cut for process and fresh utilization, respectively. The results indicate that decreasing the frequency of harvest increases profit for asparagus used in processing. This research is the first attempt to address the problem of asparagus harvesting with a bioeconomic model.Crop Production/Industries,

    AN EMPIRICAL BARGAINING MODEL OF PRICE DISCOVERY: AN APPLICATION TO THE WASHINGTON/OREGON ASPARAGUS INDUSTRY

    The bargaining process and its role in price discovery within the Pacific Northwest asparagus industry is analyzed using a general empirical bargaining model. Growers' and processors' inverse supply and demand functions define boundaries for the negotiated prices. OLS and Heckman's two-stage estimation procedures are used to estimate a stochastic bargaining model of price determination. The results indicate that basic supply and demand forces exert substantial influences on the bargaining process. In particular, expected levels of supply play a paramount role in the level of prices offered, while past prices also influence current offers. The general framework of analysis used in relation to asparagus can be generalized to other commodities where bargaining plays a role in price discovery. The model can be used to investigate the extent to which major economic forces impact bargaining behavior.Crop Production/Industries, Demand and Price Analysis,

    Includes vita."Objectives of the Study: The objective of this study was to make a case study of locational influences in meat packing in recent years, and thereby both to learn something about the location economics of that industry and to contribute to a more generalized understanding of industrial location forces in the modern setting. The organization of the study was: A. To review literature of spatial economic theory. B. To develop a theoretical framework to analyze the location pattern of an industry. C. To determine the importance of different regions of the country in the production, slaughtering, and consumption of livestock and meat for the time period 1950 through 1965. D. To determine the applicability of the theoretical framework to the static analysis of the livestock and meat industry. E. To analyze the dynamic aspects of the changing location pattern of the livestock and meat industry. F. To predict the size structure of region production, slaughter, and consumption of beef and pork for 1970 and 1975."--Page 8.Includes bibliographical references
