IMPACTS OF LIBERALIZING THE JAPANESE PORK MARKET AgEcon
Wahl, Thomas I.; Hayes, Dermot J.; Johnson, Stanley R..
The Japanese pork market is protected by a complex set of restrictions, including a variable levy and an import tariff. The combination of these policies distorts the quantity, price, and form of Japanese pork imports. An important issue relevant to the liberalization of the Japanese pork market is the accurate measurement of the price wedge between Japanese and world pork prices. The analysis indicates that the tariff equivalent of the price wedge over the 1986-88 period was 44%. If the tariff equivalent of the price wedge is reduced over a ten-year period, Japanese pork imports are projected to increase by over 39% initially and by over 215% compared to baseline projections by the year 2000. Producer welfare can be maintained by a deficiency payment...

Insuring Against Losses from Transgenic Contamination: The Case of Pharmaceutical Maize AgEcon
Ripplinger, David G.; Hayes, Dermot J.; Goggi, Susana; Lamkey, Kendall R..
Concerns about the risk of food supply contamination and the resulting financial losses have limited the development and commercialization of certain pharmaceutical plants. This article develops an insurance pricing model that helps translate these concerns into a cost-benefit analysis. The model first estimates the physical dispersal of maize pollen subject to a number of weather parameters. This distribution is then validated with the limited amount of currently available field trial data. The physical distribution is then used to calculate the premium for a fair-valued insurance policy that would fund the destruction of possibly contaminated fields. The flexible framework can be readily adapted to other crops, management practices, and regions.

Collective Marketing Arrangements for Geographically Differentiated Agricultural Products: Welfare Impacts and Policy Implications AgEcon
Lence, Sergio H.; Marette, Stephan; Hayes, Dermot J.; Foster, William E..
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...

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.

CHINESE CONSUMER DEMAND FOR ANIMAL PRODUCTS AND IMPLICATIONS FOR U.S. PORK AND POULTRY EXPORTS AgEcon
Wang, Qingbin; Fuller, Frank H.; Hayes, Dermot J.; Halbrendt, Catherine K..
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.

Welfare Impacts of Property Rights in the Seed Industry AgEcon
Lence, Sergio H.; Hayes, Dermot J.; McCunn, Alan; Smith, Stephen C.; Niebur, Bill.
The paper examines the welfare impact of different intellectual property right (IPR) regimes in private sector seed research. The model takes into account the period after expiration of IPR protection, and requires a simultaneous equilibrium in the markets for R&D, seeds, and final product (grain). Simulation results show that with the exception of R&D productivity, the optimal level of IPR protection is remarkably insensitive to parameters of the model. There is a range of IPR appropriability levels where the interests of consumers and producers (taken together) are complementary to the interests of R&D firms, and another range of appropriability levels where the welfare of producers and consumers can be increased only at the expense of the...

The Trade-off between Bioenergy and Emissions When Land Is Scarce AgEcon
Kauffman, Nathan S.; Hayes, Dermot J..
Agricultural biofuels require the use of scarce land, and this land has opportunity cost. We explore the objective function of a social planner who includes a land constraint in the optimization decision to minimize environmental cost. The results show that emissions should be measured on a per acre basis. Conventional agricultural life cycle assessments for biofuels report carbon emissions on a per gallon basis, thereby ignoring the implications of land scarcity and implicitly assuming an infinite supply of the inputs needed for production. Switchgrass and corn are then modeled as competing alternatives to show how the inclusion of a land constraint can influence life cycle rankings and alter policy conclusions.

INSURING EGGS IN BASKETS AgEcon
Hart, Chad E.; Hayes, Dermot J.; Babcock, Bruce A..
The vast majority of crop and revenue insurance policies sold in the United States are single-crop policies that insure against low yields or low revenues for each crop grown on a particular farm. This practice of insuring one crop at a time runs counter to the traditional risk management practice of diversifying across several enterprises to avoid putting all of ones eggs in a single basket. This paper examines the construction of whole-farm crop revenue insurance programs to include livestock. The whole-farm insurance product covers crop revenues from corn and soybeans and livestock revenues from hog production. The results show that at coverage levels of 95 percent or lower, the fair insurance premiums for this product on a well-diversified Iowa hog...

Economic Impact of a Ban on the Use of Over-the-Counter Antibiotics in U.S. Swine Rations AgEcon
Hayes, Dermot J.; Jensen, Helen H.; Backstrom, Lennart; Fabiosa, Jacinto F..
Antibiotic drugs are currently used in 90 percent of starter feeds, 75 percent of grower feeds, more than 50 percent of finishing feeds and at least 20 percent of sow feeds (USDA/APHIS). A ban on the use of feed-grade antibiotics would lead to changes in production processes and practices in production of pork, and hence would have an economic impact on the U.S. pork industry and pork market. This study considers the economic effects of a ban in pork production, with no change of regulation on other meats. The analysis uses a set of technical assumptions that are based in large part on a historical analysis of how the Swedish ban influenced the Swedish pork industry to anticipate the potential economic effects. A range of cases is examined. The cases use...

Market Impact of Domestic Offset Programs AgEcon
Brown, Tristan; Elobeid, Amani E.; Dumortier, Jerome; Hayes, Dermot J..
Three recent reports have estimated the market impacts of domestic offset programs, including afforestation, contained in the American Clean Energy and Security Act (ACES). The magnitude of these estimated impacts motivates this study. We show that with carbon prices as low as $30 per metric ton, a significant number of U.S. crop acres would be used to grow trees and this would cause price increases for some U.S. commodities. Although we present only one carbon price scenario, the modeling approach that we use suggests that the acreage and price impacts we describe here would increase at higher carbon prices.

Impact of the South Korea-U.S. Free Trade Agreement on the U.S. Livestock Sector AgEcon
Fabiosa, Jacinto F.; Hayes, Dermot J.; Dong, Fengxia.
The recently signed Korea-U.S. Free Trade Agreement (KORUS FTA) grants the U.S. livestock industry with preferential access to South Korea's import market. This study evaluates the likely impacts of the KORUS FTA on the U.S. livestock sector. Using the Food and Agricultural Policy Research Institute's modeling system, we find that livestock prices increase by 0.5% to 3.8% under the agreement. And together with an expansion by 381 to 883 million pounds in meat exports, the value of U.S. exports increase by close to U.S.$2 billion, or a 15.2% increase. Because of differential baseline starting market shares and differential rates and staging specifications, the beef sector results are primarily driven by trade diversion impacts, while a combination of...

ECONOMIC PERSPECTIVES ON GMO MARKET SEGREGATION AgEcon
Miranowski, John A.; Moschini, GianCarlo; Babcock, Bruce A.; Duffy, Michael D.; Wisner, Robert N.; Beghin, John C.; Hayes, Dermot J.; Lence, Sergio H.; Baumel, C. Phillip; Harl, Neil E..
Genetically modified organisms (GMO) crops have become increasingly popular with Iowa farmers over the past few years. The current genetic modifications are focused on pest management technologies. Although there were early efforts by environmental activists to disrupt the adoption of GMO technology, few concerns were raised by U.S. food retailers and consumers. The primary concern was getting European Union (EU) regulatory approval for each GMO crop variety event as late as spring 1999. The situation has changed dramatically in the last few months, and the current situation is highly uncertain. This paper provides the economic perspective on the issues surrounding non-GMO/GMO market segregation, the potential price impacts that may materialize with...

Inference Based on Alternative Bootstrapping Methods in Spatial Models with an Application to County Income Growth in the United States AgEcon
Monchuk, Daniel C.; Hayes, Dermot J.; Miranowski, John A..
This study examines correlates with aggregate county income growth across the 48 contiguous states from 1990 to 2001. Since visual inspection of the variable to be explained shows a clear spatial relationship and to control for potentially endogenous variables, we estimate a two-stage spatial error model. Given the lack of theoretical and asymptotic results for such models, we propose and implement a number of spatial bootstrap algorithms, including one allowing for heteroskedasticity, to infer parameter significance. Among the results of a comparison of the marginal effects in rural versus non-rural counties, we find that outdoor recreation and natural amenities favor positive growth in rural counties, densely populated rural areas enjoy stronger growth,...

INSURING AGAINST LOSSES FROM TRANSGENIC CONTAMINATION AgEcon
Ripplinger, David G.; Hayes, Dermot J.; Lamkey, Kendall R..
Concerns about contamination of the food supply and the financial losses that would result have limited the promise of certain genetically engineered plants. This article addresses the situation by constructing an insurance pricing model to protect against those losses. The model first estimates the physical dispersal of corn pollen subject to a number of parameters. This physical distribution is then used to calculate the premium for fair valued insurance that would be necessary to destroy contaminated fields. The flexible framework can be readily adapted to other crops, management practices, and regions.

Welfare Impacts of Cross-Country Spillovers in Agricultural Research AgEcon
Lence, Sergio H.; Hayes, Dermot J..
The welfare implications of intellectual property protection (IPP) for private sector agricultural research are analyzed, focusing on the realistic cases in which countries provide different IPP levels, technology spills over across countries, and the public sector is involved in research. A model is developed to determine who benefits from, and who should pay for, the associated research. The paper contains some interesting results on the implications of a harmonization of IPP policies through multilateral agreements or via technology that allows research firms to prevent the copying of plants and animals that express traits that have emerged from their research.
