ECONOMETRIC-PROCESS MODELS FOR INTEGRATED ASSESSMENT OF AGRICULTURAL PRODUCTION SYSTEMS - Antle, John M.; Capalbo, Susan M.
This paper develops the conceptual and empirical basis for a class of empirical economic production models that can be linked to site-specific bio-physical models for use in integrated assessment research. Site-specific data are used to estimate econometric production models, and these data and models are then incorporated into a simulation model that represents the decision making process of the farmer as a sequence of discrete or continuous land use and input use decisions. This discrete/continuous structure of the econometric process model is able to simulate decision making both within and outside the range of observed data in a way that...
TRANSPORTING THE EXPORT-BOUND GRAIN BY RAIL: A STUDY OF MARKET INTEGRATION - Miljkovic, Dragan
This study addresses the issues of market integration in railroad industry analyzing the export-bound grain transportation. A spatial analysis involving four origin states (Illinois, Iowa, Minnesota and Nebraska) and two destinations (Mexican Gulf and Pacific Northwest) is conducted in order to determine if pricing practices by the same or different railroads in different regions are consistent. A system of structural equations is estimated and dynamic regression tests are conducted because of the dynamic nature of interregional trade and arbitrage activities. The results indicate that grain transportation market by rail is not perfectly integrated. This is primarily due to numerous mergers...
ECONOMICS OF AGRICULTURAL SOIL CARBON SEQUESTRATION IN THE NORTHERN PLAINS - Antle, John M.; Capalbo, Susan M.; Mooney, Sian; Elliott, Edward T.; Paustian, Keith H.
Under the Kyoto protocol of the United Nations Framework Convention on Climate Change the United States is charged with reducing emissions of greenhouse gases to seven percent below their 1990 levels by the period 2008-2012. These reductions could be met from many industries including agriculture. In this paper, an economic simulation model is linked to an ecosystem model to quantify the economic efficiency of policies that might be used to sequester carbon (C) in agricultural soils in the Northern Plains region. Simulations with the Century ecosystem model show that long-term soil C levels associated with a crop/fallow system are less...
EVALUATING TELEMEDICINE IN RURAL SETTINGS: ISSUES AND APPLICATIONS - Capalbo, Susan M.; Heggem, Christine N.
Changes in health care policies, demographics, and technology have presented new opportunities for the delivery of medical care services and information to rural communities. Telemedicinethe use of electronic information and communications technologies to provide and support health care when distances separates the participantsis one technology that has impacted the efficiency of delivery of rural health care services. This paper presents an overview of the telemedicine technologies, government involvement in support of telemedicine, evaluation efforts to date for these technologies, and issues that need to be addressed in designing an economic-based framework to evaluate the net benefits of telemedicine technologies to...
TECHNOLOGICAL CHANGE IN THE U.S. BEEF AND PORK SECTORS: IMPACTS ON FARM-WHOLESALE MARKETING MARGINS AND LIVESTOCK PRICES - Marsh, John M.; Brester, Gary W.
Real livestock prices and farm-wholesale marketing margins have steadily declined over the past 20 years. Many studies have examined the effects of increasing packer concentration on these declines. However, most have generally failed to account directly for technological change in livestock production and red meat slaughtering. We estimate reduced form models for beef and pork farm-wholesale marketing margins and cattle and hog prices that specifically include measures of technological change. Empirical results indicate that meat packing technology has reduced real margins and technological change embodied in cattle and hog production accounts for substantial declines in real slaughter cattle and hog...
FARM-LEVEL CHARACTERISTICS OF SOUTHERN NEBRASKA FARMS/RANCHES WITH ANNUALLY-PLANTED CROPS - Antle, John M.; Capalbo, Susan M.; Heggem, Christine N.; Clark, Richard T.; Norton, Nancy A.; Selley, Roger A.
The information presented in this report represents data collected from farming and ranching operations in the southern two tiers of counties in Nebraska. This study was based on a random sample of 151 southern Nebraska farms that have annually-planted crop acreage. Information was obtained for the 1997 crop year. This data set is referred to as the MSU/UNL survey data. From the MSU/UNL survey data, the average size of the farming operations in the survey, in 1997, was 1,316 acres. Of these, 856 acres were planted to annual crops, and the remaining 460 acres included 61 acres in fallow, 29...
GOVERNMENT POLICIES AND ON-FARM WHEAT ALLOCATION IN RURAL CHINA - Buschena, David E.; Smith, Vincent H.; Di, Hua
Market-oriented policy reforms have potentially important effects on farm-level grain production and utilization decisions in developing countries. This paper provides an empirical evaluation of the potential effects of market liberalization in China on farm-level wheat consumption,
market sales, and on-farm storage. The results indicate that price changes have economically important impacts on utilization decisions by farm families through both income and substitution effects and that off- farm income also appears to be significant. The potential to earn off-farm
income is also shown to be an important factor in grain utilization decisions. Storage is affected by government procurement policies as well as by...
PERFECT SUBSTITUTES: A NOTE ON THE ALCHIAN-ALLEN HYPOTHESIS - Vedrashko, Alexander; Smith, Vincent H.
Alchian and Allen hypothesized that a country will export high rather than low quality goods. Here we show that if the inherent attributes of the commodities are identical the country will only export the high-quality good.
GRAIN QUALITY AND NORTH AMERICAN HARD WHEAT EXPORTS - Wilson, William W.; Dahl, Bruce L.
Past debate on competition and quality in international wheat markets has focused on class and country of origin as the salient source of differentiation. This study analyzes changes in demand for both wheat classes and grades. Comparisons are made between Canadian and U.S. hard wheats, principal competitors in the hard wheat market. Both countries are dominant producers of Hard Red Spring Wheat (HRS in the United States and Canadian Western Red Spring [CWRS] in Canada); the United States is the dominant producer of Hard Red Winter (HRW); and both countries are large producers of durum (Hard Amber Durum [HAD] in...
