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.

Theses, Projects, and Africana Materials Management in Nigerian Academic Libraries: The Case of Hezekiah Oluwasanmi Library

This is a survey of the procurement, organization and use of unpublished projects, theses, and Africana mateials in Hezekiah Oluwasanmi Library, Obafemi Awolowo University, Ile-Ife, Nigeria. The Africana section conserves knowledge, preserves cultural heritage, provides information, and supports education and research. This paper the location, mode of processing, circulation, and terms of availability of these materials. Recommendations are made on how to manage Africana materials in academic libraries where they constitute a vital component of collections.

Trade Liberalization, Corn Prices and a Rural Community in Guatemala

Trade liberalization policies in Guatemala have impacted agricultural production. This thesis focuses on how trade liberalization has happened, what have been the impacts at a national level and describes how a community has adapted to the implementation of these policies. The implementation of trade was influenced by several, international and national institutions. Among the international institutions are the World Bank, the World Trade Organization and the United States Agency for International Development. At the national level the institutions that have partaken in shaping the trade policies are the military and the owners of capital and labor. The implementation of trade policies at a national level has affected national corn prices, population level diets and to some extent reduced poverty levels. At a local level trade liberalization policies have impacted land holdings, increased intensification of agriculture, including agrochemical, machinery and crop plantations per year, and consumption rates of corn have been affected. Maximization of the benefits and minimization of the detrimental effects can happen with the implementation of policies that promote food security, improve access to health and education, and prevent environmental and human health consequences from the intensification of agriculture and at the same time continue with the production of non-traditional agricultural products.
