Economic events may cause structural changes in markets. To know the effect of the economic event we should analyze the structural changes in the market demand and supply. The purpose of this dissertation is to analyze the effect of selected economic events on market demand and supply using econometric models. Structural changes can be modeled according to the types of changes. For an abrupt and instantaneous break, a dummy variable model can be used. For a smooth and gradual movement, proxy variables which represent the event can be applied, if we know the variables. If we don‟t know the appropriate proxy variables, a smooth transition regression model can be employed. The BSE (Bovine Spongiform Encephalopathy) outbreak in the U.S. in 2003 is assumed to make abrupt and instantaneous changes in Korean meat consumption. To analyze the effect on Korean meat consumption, the Korean demands of beef, pork, chicken, and U.S. beef are estimated using an LA/AIDS (Linear Approximate Almost Ideal Demand System) model with the dummy variable specifying the time before and after the BSE. From the results we can confirm that food safety concerns caused by the BSE case changed Korean meat consumption structure. Korean beef and U.S. beef became less elastic, and pork and chicken got more elastic to budget. Korean beef became less price elastic, but pork and U.S. beef got more price elastic. The changes of U.S. natural gas supply caused by technology development and depletion in reserves are analyzed using a smooth transition regression model. From the results, we can confirm that the productivity improvement by technology development is greater than the labor cost increase by depletion, but not greater than the capital cost increase by depletion in mid-2000s. The effects of posting the winning bid in a repeated Vickrey auction are examined using a proxy variable. By applying an unobserved effect Tobit model to the experimental auction done by Corrigan and Rousu (2006) for a candy bar, we can confirm that the changes of bidding behavior are significant, especially when the winning bid is high. By extracting the bid affiliation effects, we showed that true willingness to pay can be estimated.

The bovine spongiform encephalopathy (BSE) crisis was a significant shock to the Canadian agricultural sector. On May 20, 2003, it was announced that an animal infected with BSE had been identified. The economic aftermath of this discovery was described as horrendous (AGO, 2004). Economic crises, such as the Canadian BSE agricultural crisis, are rare events. The rarity of these episodes supplies a unique opportunity for analysis. According to a policy review by the Alberta Auditor General (AGO, 2004), the agricultural economics discipline appeared to be of little assistance in the crisis policy design process. This research addresses this problem by exploring economic theory and policy via detailed empirical investigation. Specifically, this study evaluates agricultural support policies and producer risk preferences in the aftermath of the Canadian BSE crisis. Three research chapters address questions related to cow-calf producer behaviour and government policy. Chapter 2 focuses on designing emergency aid programs and calculating short-run quantitative benchmarks for crisis relief at the farm-level. Chapter 3 estimates observed risk preferences for a sample of Albertan cow-calf producers. Differential risk preferences help to explain diverse production responses following agricultural crises. The final research chapter, chapter 4, examines Canadas primary risk management program when there is potential for catastrophic price risk. In particular, vertical and horizontal equity criteria are used to scrutinize the distribution of net AgriStability benefits across a heterogeneous sample of cow-calf producers.

Thesis (M.A. in agribusiness)--Washington State University. / Includes bibliographical references.

In December of 2003, the U.S. Secretary of Agriculture announced the presence of Bovine Spongiform Encephalopathy (BSE) within a cow in the state of Washington. The announcement prompted the cessation of beef imports by the largest traditional beef trading partners with the United States, resulting in immediately realized losses to the U.S. industry. This thesis evaluates the short- and long-term impact this discovery and subsequent policies had on the global beef market. We utilize market share analysis to examine the loss realized by the U.S. over a 13-year time frame, then employ a log-linear gravity model with fixed effects to quantify the changes in global export and import values and quantities using a novel bilateral trade database spanning 16 years. We find that the policies implemented immediately on discovery of the single BSE case were often slow to be rescinded even though additional related cases of BSE were not found in the United States. We also find that the removal of said policies does not guarantee full reentry of U.S. beef products, even after a lag of several years. Finally, we find that both traditional and newly emerging suppliers of beef and beef products contributed to the slow reentry of U.S. beef within critical markets. The losses and implications of the aforementioned policies detailed within this thesis suggests a different approach be undertaken by regulators should another similar threat to the U.S. food supply emerge in the future. / Master of Science
