Última A Comparative Analysis of Regional Production Costs of Fed Beef Produced for the U.S. and Japanese Markets AgEcon Sankey, Lee; Hayes, Dermot J.; Clemens, Roxanne. This study compared and analyzed actual 1989 production costs for representative regional feedlots in the U.S. The results show that grain-surplus regions have lower total costs and poorer feeding efficiencies. The analysis suggests that Iowa has a comparative advantage in producing heavily marbled beef required by the Japanese market. Southwestern states have an advantage in producing leaner beef and stand to benefit if U.S. consumers develop a taste for Select-quality beef.

Ano: 1993 URL: http://purl.umn.edu/62329 A Nonlinear Offset Program to Reduce Nitrous Oxide Emissions Induced by Excessive Nitrogen Application AgEcon Rosas, Francisco; Babcock, Bruce A.; Hayes, Dermot J.. On average, U.S. farmers choose to apply nitrogen fertilizer at a rate that exceeds the ex post agronomically optimal rate. The technology underlying the yield response to nitrogen rewards producers who over apply in years when rainfall is excessive. The overapplication of nutrients has negative environmental consequences because the nitrogen that is not taken up by the plant will typically volatilize causing N2O emissions, or leach causing water pollution. We present a nonlinear offset program that induces farmers to reduce their nitrogen applications to the level that will be consumed by the plant in a typical year and, as a result, reduce N2O emissions from agriculture. The offset program is nonlinear because of the nonlinear relationship between N2O...

Ano: 2011 URL: http://purl.umn.edu/103914 A Study of the Factors that Influence Consumer Attitudes Toward Beef Products Using the Conjoint Market Analysis Tool AgEcon Mennecke, Brian; Townsend, Anthony M.; Hayes, Dermot J.; Lonergan, Steven. This study utilizes an analysis technique commonly used in marketing, the conjoint method, to examine the relative utilities of a set of beef steak characteristics considered by a national sample of 1,432 U.S. consumers, as well as additional localized samples representing undergraduate students at a business college and in an animal science department. The analyses indicate that among all respondents, region of origin is by far the most important characteristic; this is followed by animal breed, traceability, the animal feed used, and beef quality. Alternatively, the cost of cut, farm ownership, the non-use of growth promoters, and whether the product is guaranteed tender were the least important factors. Results for animal science undergraduates are...

Ano: 2006 URL: http://purl.umn.edu/18539 A Welfare Analysis of the U.S. Ethanol Subsidy AgEcon Du, Xiaodong; Hayes, Dermot J.; Baker, Mindy L.. Based on a transparent analytical model of multiple markets including corn, ethanol, gasoline, and transportation fuel, this study estimates the welfare changes for consumers and producers resulting from ethanol production and related support polices in 2007. The welfare estimation takes into account the second-best gain from eliminating loan deficiency payments. The results suggest the total social cost is about $0.78 billion for given market parameters. We validate the model’s underlying assumption and test for the results’ sensitivity to assumed parameters.

Ano: 2008 URL: http://purl.umn.edu/7106 AN ANALYSIS OF REGIONAL ECONOMIC GROWTH IN THE US MIDWEST AgEcon Monchuk, Daniel C.; Miranowski, John A.; Hayes, Dermot J.; Babcock, Bruce A.. In this paper we examine more closely some of the forces that underlie economic growth at the county level. In an effort to describe a much more comprehensive regional economic growth model, we address a variety of different growth hypotheses by introducing a large number of growth related variables. When formulating our hypotheses and specifying our growth model we make liberal use of GIS mapping software to “"paint"” a picture of where growth spots exist and why. Our empirical estimation indicates amenities, state and local tax burdens, population, amount of agricultural activity, and demographics have important economic growth impacts.

In an effort to describe a much more comprehensive regional economic growth model, we address a variety of different growth hypotheses by introducing a large number of growth related variables. When formulating our hypotheses and specifying our growth model we make liberal use of GIS (geographical information systems) mapping software to "paint" a picture of where growth spots exist. Our empirical estimation indicates that amenities, state and local tax burdens, population, amount of primary agriculture activity, and demographics have important impacts on economic growth.

Ano: 2005 URL: http://purl.umn.edu/18552 An Insurance Approach to Risk Management in the Ethanol Industry AgEcon Paulson, Nicholas D.; Babcock, Bruce A.; Hart, Chad E.; Hayes, Dermot J.. The vast majority of crop and revenue insurance policies sold in the United States are single-crop policies that insure against low yields or revenues for each crop grown on the farm. But, increasingly, producer income is based more on the value of crops that have been converted into a value-added product such as ethanol. Moreover, the recent increases in energy and com-modity price levels and volatilities emphasize the importance of risk management to ethanol investors. This paper uses an insurance approach to outline a risk management tool which mimics the gross margin level of a typical corn-based ethanol plant. The gross margin, pre-mium, and indemnity levels are calculated on a per bushel basis to enable producers/investors to utilize the product...

We examined four evolution paths of the biofuel sector using a partial equilibrium world agricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. The third scenario considers a pure market force driving ethanol demand growth because of the high energy price, while the last is a policy-induced shock with removal of the biofuel tax credit when the energy price is high. Standard results hold where...

We examine four scenarios for the evolution of the biofuel sector using a partial equilibrium model of the world agricultural sector.

This paper examines Chinese consumer preference for major animal products and assesses the potential impacts of a reduction in China's import tariff on its pork and poultry demand and net import. Our analysis suggests that China's demand for animal products will continue to grow as income increases. Using a trade model, results of our scenario analysis indicate that a reduction in China's import tariffs will significantly increase its net pork and poultry imports and the U.S. will capture most of the increases. Nevertheless, the impact on the market price in China and the U.S. is likely to be very small.

This paper examines the incentive of atomistic agricultural producers within a specific geographical region to differentiate and collectively market products. We develop a model that allows us to analyze the market and welfare effects of the main types of real-world producer organizations, using it to derive economic insights regarding the circumstances under which these organizations will evolve, and describing implications of the results obtained in the context of an ongoing debate between the European Union and United States. As the anticipated fixed costs of development and marketing increase and the anticipated size of the market falls, it becomes essential to increase the ability of the producer organization to control supply in order to ensure the...

Ano: 2006 URL: http://purl.umn.edu/18704 Creating a Geographically Linked Brand for High-Quality Beef: A Case Study AgEcon Clemens, Roxanne; Lawrence, John D.; Hayes, Dermot J.; Babcock, Bruce A.. Worldwide, a segment of consumers can afford to pay substantial price premiums for very high quality agricultural products with attributes those consumers value. At the same time, many U.S. farmers are producing these high-quality products but are not using market mechanisms that allow them to take fullest advantage of price premiums. This paper describes a pilot program developed to commercialize an origin-based collective brand for very high quality beef. We hypothesize that, if successful, the program would create potential for cattle producers to take fuller advantage of price premiums often captured elsewhere in the marketing channel. Specifically, the pilot program analyzed two mechanisms for differentiating and marketing very high quality beef: a...

Ano: 2007 URL: http://purl.umn.edu/8509 CROP INSURANCE RATES AND THE LAWS OF PROBABILITY AgEcon Babcock, Bruce A.; Hart, Chad E.; Hayes, Dermot J.. Increased crop insurance subsidies have increased the demand for insurance at coverage levels higher than the traditional level of 65 percent. Premium rates for higher levels of yield insurance under the Federal Actual Production History (APH) program equal the premium rate at the 65 percent coverage level multiplied by a rate relativity factor that varies by coverage level but not by crop or region. In this paper, we examine the consistency of these constant rate relativity factors with the laws of probability by determining the maximum 65 percent premium rate that is consistent with a well-defined yield distribution. We find that more than 50 percent of U.S. counties have premium rates for corn, soybeans, and wheat that are not consistent with the laws...

Ano: 2002 URL: http://purl.umn.edu/18345 Crop-Based Biofuel Production under Acreage Constraints and Uncertainty AgEcon Baker, Mindy L.; Hayes, Dermot J.; Babcock, Bruce A.. A myriad of policy issues and questions revolve around understanding the bioeconomy. To gain insight, we develop a stochastic and dynamic general equilibrium model and capture the uncertain nature of key variables such as crude oil prices and commodity yields. We also incorporate acreage limitations on key feedstocks such as corn, soybeans, and switchgrass. We make standard assumptions that investors are rational and engage in biofuel production only if returns exceed what they can expect to earn from alternative investments. The Energy Independence and Security Act of 2007 mandates the use of 36 billion gallons of biofuels by 2022, with significant requirements for cellulosic biofuel and biodiesel production. We calculate the level of tax credits required... Tipo: Conference Paper or Presentation Palavras-chave: Crop Production/Industries; Resource /Energy Economics and Policy.

Ano: 2008 URL: http://purl.umn.edu/6314 Dynamics of Biofuel Stock Prices: A Bayesian Approach AgEcon Du, Xiaodong; Hayes, Dermot J.; Yu, Cindy L.. We use Bayesian Markov Chain Monte Carlo methods to investigate the linkage between the volatility of ethanol security prices and the uncertainty surrounding the profitability of ethanol production and the price variations of non-ethanol energy securities. The joint evolution of return and volatility is modeled as a stochastic process that incorporates jumps in both return and volatility. While a strong and significant correlation is found between the volatility of ethanol securities and profit uncertainty from June 2005 to July 2008, the dynamic pattern of ethanol stock volatility is strikingly similar to that of the S&P 500 energy sector index in the more recent period. Our evidence lends support to the findings in the literature on rational learning...
