Evaluating Alternative Techniques For Forecasting Industrial And Occupational Employment, Drew A. Varnado Jan 2014

Evaluating Alternative Techniques For Forecasting Industrial And Occupational Employment, Drew A. Varnado

LSU Doctoral Dissertations

This paper offers three different regional output-by-industry forecasting techniques (time series, Social Accounting Matrix (SAM)-based, and Computable General Equilibrium (CGE)-based) and two different occupation-by-industry matrices (national and state geographies) for use in the creation of industry/occupation employment forecasts. Estimates are compared to actual data from eight years from 2001 to 2010. OLS regressions are run to determine how well modeled employment estimates fit actual employment for the state of Louisiana. A meta-analysis style regression of the R-sqaured values on model characteristics (accounted for using Boolean dummy-variables) determines that industrial output forecasting techniques do not provide statistically different ...


Three Essays On U.S. Meat Goat Production: Goal Structure, Selection Of Breeding Stock, And Meat Goat Marketing, Narayan Prasad Nyaupane Jan 2014

Three Essays On U.S. Meat Goat Production: Goal Structure, Selection Of Breeding Stock, And Meat Goat Marketing, Narayan Prasad Nyaupane

LSU Doctoral Dissertations

This study investigates three major areas of U.S. meat goat production – goal structure, selection of breeding stock, and marketing, by using survey data received from U.S. meat goat producers. Of 1,600 producers surveyed, 584 usable responses were obtained with an adjusted response rate of 43%. The fuzzy pair-wise comparison method was used to determine producer goal structure. The results showed that profit maximization and leisure-related goals were highly considered goals and controlling weeds/vegetation and increasing farm size were the least considered goals by U.S. meat goat producers. A choice-based conjoint study was conducted to identify ...


United States Meat Goat Production Economic Performance Measures: A Stochastic Production Frontier Analysis, Berdikul Qushim Jan 2014

United States Meat Goat Production Economic Performance Measures: A Stochastic Production Frontier Analysis, Berdikul Qushim

LSU Doctoral Dissertations

The meat goat industry is relatively a newcomer to the U.S. agricultural production and one of the fastest growing livestock industries in the U.S. Despite the growth of the meat goat industry, little is known about meat goat production economics. Information is needed concerning the drivers of production efficiency, optimum size of operation, and scope economies in the industry. A nationwide mail survey of U.S. meat goat producers who advertise their meat goat production via the internet for this efficiency analysis was conducted. Costs and returns data for 2011 expenses from those meat goat producers were collected ...

Application Of Choice-Based Conjoint Analysis To Determine Consumers' Preferences And Willingness To Pay For Grass Fed Beef In The United States, Franklin Fernando Vaca Moran Jan 2014

Application Of Choice-Based Conjoint Analysis To Determine Consumers' Preferences And Willingness To Pay For Grass Fed Beef In The United States, Franklin Fernando Vaca Moran

LSU Doctoral Dissertations

U.S. consumption of beef has declined during the last three decades. Consumer preferences have shifted toward products that are considered healthy, environmentally friendly and obtained through sustainable production methods. Because of the characteristics of grass-fed beef production, consumers are becoming more interested in grass-fed beef products than conventional beef products. A choice-based experiment was used to assess consumer’s preferences for grass-fed beef. A national online survey was conducted in May 2012 and the information from 4000 respondents was collected from the entire U.S. The respondents were divided in two groups of similar size: grass-fed beef eaters, comprised ...


The Worlds Of Agriculture In Asia : Agricultural And Economic Development, Lorna Econg Amrinto Jan 2014

The Worlds Of Agriculture In Asia : Agricultural And Economic Development, Lorna Econg Amrinto

LSU Doctoral Dissertations

The agro-fundamentalists consider agriculture as the engine of growth while agro-pessimists argue that economic growth causes agricultural productivity. It is the main engine of growth in agriculture-based countries; less important in transforming economies; and plays the same role as other tradable sectors in urbanized countries (World Bank, 2008). This work revisits agriculture’s role in the development process within the experience of Asia where the majority of the population heavily depends on agriculture. Chapter 2 presents the results of causality tests between agriculture and economic growth in bivariate systems using the TYDL methodology. For some of agriculture-based Asia (Bhutan, Lao ...

LSU Master's Theses

The purpose of this thesis is to study the empirical linkages between nearby futures prices for coffee at the New York (NY) Intercontinental Exchange (ICE)/NY Board of Trade (NYBOT) and cash prices (producer and export prices) in selected Latin American countries. This theme was entertained in Fortenbery and Zapata (2004) and subsequently by Fortenbery and Zapata (2004) and Li and Fortenbery (2013). This thesis uses data from January 1990 to May 2013 and adds producer cash prices in addition to export prices, thus expanding the dataset by over a decade and adding local market cash prices relative to the ...


A Factor Analysis Of The Dimensions Of Economic Damages From Tropical Storms And Hurricanes In Louisiana, James Luke Boutwell Jan 2014

A Factor Analysis Of The Dimensions Of Economic Damages From Tropical Storms And Hurricanes In Louisiana, James Luke Boutwell

LSU Master's Theses

Coastal communities are highly sensitive to disturbances from tropical storms and hurricanes. This is particularly true in Louisiana and along the U.S. Gulf Coast where economies are largely dependent on tourism and natural resource based industry. Since Hurricane Katrina and, more recently, Hurricane Sandy, there has been an increase in concern for how coastal communities will mitigate and respond to the impacts of coastal storms. These concerns are made more acute by the increasing population concentrated along the coast and the risk of more frequent and more severe coastal storms in the future. A commonly advocated-for method of storm ...


Estimating U.S. Household Seafood Demand Based On Longitudinal And Cross-Sectional Data, Huabo Wang Jan 2014

Estimating U.S. Household Seafood Demand Based On Longitudinal And Cross-Sectional Data, Huabo Wang

LSU Doctoral Dissertations

This overall goal of this research is to examine and update U.S. at-home household demand estimates for seafood (including species and generic products) that can be used in policy formulation (by both the private and public sector). As such, this study estimated quantity-based household demand functions for seafood in aggregate, by generic product form (fresh, frozen, and prepared), and primary species. Given that the role of quality has been shown to significantly influence expenditures and seafood demand, this paper also seeks to incorporate the household quality choice into the demand model. In order to help to tailor the market ...

Analysis Of Media Coverage Of Selected Food Safety Events On The Demand For The Recalled Products, Abhishek Bhagwat Bharad

LSU Doctoral Dissertations

The major focus of this study was to identify the linkage between information and consumer behavior and to examine the role that a new media index played in the identifying the tone of news stories. Past studies have relied on using the number of media stories but, this study tests a new approach, i.e., in order to analyze the effect of information by incorporating the sentiment indices. These indices were created based on the tone of the news story. The results from sentiment indices were compared to the results from the information index. Barten’s Synthetic model (BSM) was ...

Planted acreage of cotton in Louisiana has decreased over the past several years due to higher cotton variable production costs, stagnant cotton market prices, and higher grain yields and market prices for corn and soybeans. The general objective was to determine the economic impact of the adoption and use of an onboard module building cotton harvest system on the ability of the cotton enterprise to compete for planted acreage in the mixed crop farming areas of Louisiana. Specific research objectives included the estimated of comparative ownership and operating costs for the module building harvest systems relative to existing basket/module ...


Remittance And Migration: Impact On Technology Adoption, Natural Resource Conservation, And Household Welfare, Deborah Ann Williams Jan 2014

Remittance And Migration: Impact On Technology Adoption, Natural Resource Conservation, And Household Welfare, Deborah Ann Williams

LSU Master's Theses

Nepal is the perfect country to study all the facets of migration, sustainable agriculture and their subsequent impact on food systems. Droves of migrants are leaving rural Nepal for higher incomes to cover household daily expenses. The Government of Nepal (GON) encourages migration as a means to reduce poverty, and remittance already amounts to 25.83% of GDP, and it is expected to grow (Nepal Bastra Bank 2014, Thieme and Wyss 2005, Yang 2011). However, it is still unclear whether the mass exodus from rural areas and the growing dependence on remittance, the portion of the migrant workers' earnings sent ...


Exchange Rate Volatility Effects On Brics Countries Exports, David Isaias Maradiaga Pineda Jan 2014

Exchange Rate Volatility Effects On Brics Countries Exports, David Isaias Maradiaga Pineda

LSU Doctoral Dissertations

The leaders of the leading emerging economies Brazil, Russia, India, China, and South Africa (BRICS) claim that increased currency exchange rate volatility (CERV) from USD, EUR, and JPY (G-3) negatively impacts their exports, and expressed their desire for less trade dependence on these currencies. The literature on the impact of CERV on trade is vast. However, no consensus on the impact’s direction and significance has been reached yet. The motivation of this study was: first, to contribute to the existing empirical literature by using an alternative methodology; and second, to provide empirical evidence to the claim’s validity or ...


Factors Influencing Adoption Of Vsh Queens In The Honey Breeding Industry, Julie Leiby Jan 2014

Factors Influencing Adoption Of Vsh Queens In The Honey Breeding Industry, Julie Leiby

LSU Master's Theses

There are many threats that contribute to the decline in honey bee colonies around the United States; among them is the Varroa mite, Varroa destructor. The Varroa mite is a significant threat to honey bees and, by extension, beekeepers across the United States. It is suspected to be one of the main contributors to the increase in colony collapse and the decline in bee numbers and the beekeeping industry (Danka, May 2013). Fifty-five percent of beekeepers exited beekeeping between 1987 and 2002 (USDA). Although honey production continued to decrease through 2007, the number of beekeepers entering beekeeping had increased (USDA ...
