Essays on Industrial Organization and Environmental Economics

This dissertation studies environmental regulation issues in the hog production industry as well as forces behind the reorganization of the industry during the past two decades. Federal and State-level environmental regulations imposed on U.S. hog production during the year 2003 are examined in Chapter 1. Based on the number of regulations passed by the Federal government and states, the 2003 regulatory index is constructed. The regulatory stringency index suggests that state-level regulations vary across states and have increased over the years. In addition, state-level regulations are more stringent than federal regulations. Chapter 2 develops an empirically implementable theoretical model which allows us to investigate the long-run effects of environmental regulations on the U.S. hog industry. Hog feeding operations (HFOs) are divided into large feeding operations (LHFOs) and small feeding operations (SHFOs). The impact of the presence of a large number of LHFOs on the entry and exit of CHFOs is also examined. Results of this study suggest that: Increased state-level regulation stringency significantly lowers the output of SHFOs; increased state-level regulation stringency significantly lowers the output of LHFOs; increased state-level regulation stringency significantly lowers the number of SHFOs; SHFO output rises significantly in states that have a greater number of LHFOs; LHFO output rises significantly in states that have a greater number of LHFOs; the number of SHFOs significantly increases in states that have a greater numbers of LHFOs; regulation increases the average SHFO size; and regulation decreases the average LHFO size. Chapter 3 examines the importance of input availability, market attractiveness, agglomeration economies and environmental regulations on the reorganization of U.S. hog production for a panel of 22 U.S. hog producing states which include, Northern states, Southern states and Midwest states for the period 1994-2006. Results from this study suggest that: Hog production in a state is positively affected by hog production in a nearby state, confirming the presence of agglomeration economies; Environmental regulations and high corn price have negative effects on state-level U.S. hog production; High hog prices, and favorable labor cost, and land values attract hog production; and transportation cost has no effect on hog production.

Studies on the Helminth Fauna of Alaska. XLI. Observations on Cestodes of the Genus Diplogonoporus Lönnberg, 1892 (Diphyllobothriidae)

The study of a collection of cestodes assigned to the genus Diplogonoporus Lönnberg, 1892 disclosed but two species, D. balaenopterae Lönnberg, 1892, and D. tetrapterus (von Siebold, 1848) (provis.). These cestodes occur characteristically in marine mammals but occasionally are found in terrestrial hosts; D. balaenopterae is recorded for the first time from the domestic dog, and it is concluded that D. grandis (Blanchard, 1894), from man, is conspecific with D. balaenopterae. The latter species is recorded for the first time from the humpback whale, Megaptera novaeangliae (Borowski). The relatively small D. tetrapterus, a common parasite of the Steller sea lion, Eumetopias jubata (Schreber), is reported for the first time from the sea otter, Enhydra lutris Linnaeus, and from the domestic mink, Mustela vison Schreber. Descriptions of representative specimens are presented, and the taxonomic status of other species assigned to Diplogonoporus is discussed. Although the diplogonadic organization of these cestodes is somewhat variable, it is nevertheless constant and serves to characterize the genus Diplogonoporus. The process of asexual reproduction by means of transverse subdivision of primary segments is described. This ability and the diplogonadic structure of these cestodes are considered to be adaptations that increase the production of eggs and thereby the probability of reproductive success in the marine habitat.

The People's Hour and the Social Gospel: George Howard Gibson's Gilded Age Search for an Organization of the Kingdom of God

Previous studies of the Social Gospel movement have acknowledged the fact that Social Gospelers were involved in multiple social reform movements during the Gilded Age and into the Progressive Era. However, most of these studies have failed to explain how the reform experiences of the Social Gospelers contributed to the development of the Social Gospel. The Social Gospelers’ ideas regarding the need to transform society and their strategies for doing so were largely a result of their personal experiences as reformers and their collaboration with other reformers. The knowledge and insight gained from interaction with a variety of reform methods played a vital role in the development of the ideology and theology of the Social Gospel. George Howard Gibson is exemplary of the connections between the Social Gospel movement and several other social reform movements of the time. He was involved in the Temperance movement, was a member of both the Prohibition Party and the People’s Party, and co-founded a Christian socialist cooperative colony. His writings illustrate the formation of his identity as a Social Gospeler as well as his attempts to find an organization through which to realize the kingdom of God on earth. Failure to achieve the changes he desired via prohibition encouraged him to broaden his reform goals. Like many Midwestern Social Gospelers Gibson believed he had found “God’s Party” in the People’s Party, but he rejected reform via the political system once the Populists restricted their attention to the silver issue and fused with the Democratic Party. Yet his involvement with the People’s Party demonstrates the attraction many Social Gospelers had to the reforms proposed in the Omaha Platform of 1892 as well as to the party’s use of revivalistic language and emphasis on producerism and brotherhood. Gibson’s experimentation with a variety of ways to achieve the kingdom of God on earth provides new insight into the experiences and contributions of lay Social Gospelers. Adviser: Kenneth J. Winkle
