The Impact of Ethanol Production on US and Regional Gasoline Markets: An Update to May 2009 AgEcon
Du, Xiaodong; Hayes, Dermot J..
This report updates the findings in Du and Hayes 2009 by extending the data to December 2010 and concludes that over the sample period from January 2000 to December 2010, the growth in ethanol production reduced wholesale gasoline prices by $0.25 per gallon on average. The Midwest region experienced the biggest impact, with a $0.39/gallon reduction, while the East Coast had the smallest impact at $0.16/gallon. Based on the data of 2010 only, the marginal impacts on gasoline prices are found to be substantially higher given the much higher ethanol production and crude oil prices. The average effect increases to $0.89/gallon and the regional impact ranges from $0.58/gallon in the East Coast to $1.37/gallon in the Midwest. In addition, we report on a related...

Biofuels: Potential Production Capacity, Effects on Grain and Livestock Sectors, and Implications for Food Prices and Consumers AgEcon
Hayes, Dermot J.; Babcock, Bruce A.; Fabiosa, Jacinto F.; Tokgoz, Simla; Elobeid, Amani E.; Yu, Tun-Hsiang (Edward); Dong, Fengxia; Hart, Chad E.; Chavez, Eddie C.; Pan, Suwen; Carriquiry, Miguel A.; Dumortier, Jerome.
We examine four scenarios for the evolution of the biofuel sector using a partial equilibrium model of the world agricultural sector. The model includes the new Renewable Fuels Standard in the 2007 energy act, the 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. Of the remaining two scenarios, one considers a pure market force driving ethanol demand growth because of the high energy price while the other is a policy-induced shock with removal of the biofuel tax...

FARMER-OWNED BRANDS? AgEcon
Hayes, Dermot J.; Lence, Sergio H.; Stoppa, Andrea.
The paper lays out the economic arguments in favor of the establishment of farmer-owned brands in midwestern agriculture and presents four case studies based on successful efforts in this area in the United States and European Union. The case studies involve Parma Ham, Brunello di Montalcino wine, Vidalia onions, and a third-party verification organization. The studies show that these brands can be profitable for farmers and emphasize the importance of restricting the supply of any successful brand. One of the case studies shows that this type of supply control can conflict with antitrust regulations.

Speculation and Volatility Spillover in the Crude Oil and Agricultural Commodity Markets: A Bayesian Analysis AgEcon
Du, Xiaodong; Yu, Cindy L.; Hayes, Dermot J..
This paper assesses the roles of various factors influencing the volatility of crude oil prices and the possible linkage between this volatility and agricultural commodity markets. Stochastic volatility models are applied to weekly crude oil, corn and wheat futures prices from November 1998 to January 2009. Model parameters are estimated using Bayesian Markov chain Monte Carlo methods. The main results are as follows. Speculation, scalping, and petroleum inventories are found to be important in explaining oil price variation. Several properties of crude oil price dynamics are established including mean-reversion, a negative correlation between price and volatility, volatility clustering, and infrequent compound Poisson jumps. We find evidence of volatility...

LAND ALLOCATION IN THE PRESENCE OF ESTIMATION RISK AgEcon
Lence, Sergio H.; Hayes, Dermot J..
Estimation risk occurs when parameters relevant for decision making are uncertain. Bayes'’ criterion is consistent with expected-utility maximization in the presence of estimation risk. This article examines optimal (Bayes’') land allocations and land allocations obtained using the traditional plug-in approach and two alternative decision rules. Bayes’' allocations are much better economically than the other allocations when there are few sample observations relative to activities. Calculation of certainty equivalent returns (CERs) with estimation risk is also discussed and illustrated. CERs are typically (and incorrectly) calculated with the plug-in approach. Plug-in CERs may be extremely misleading.

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.

EXPERIMENTAL METHODS IN CONSUMER PREFERENCE STUDIES AgEcon
Fox, John A.; Hayes, Dermot J.; Shogren, Jason F.; Kliebenstein, James B..
Controlled experimental auctions can be used to elicit preferences for food products. We describe results from two series of experiments in which subjects revealed their willingness-to-pay for safer food. In one series, the risk reduction technology was not specified; in the other, it was identified as food irradiation. The results provide some evidence on the acceptability of food irradiation as a risk reduction technology.

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..
The U.S. pork industry routinely adds antibiotics to rations of weaned pigs both to prevent illness before symptoms emerge and to increase growth rates. The European Union (EU) is in the process of restricting feed use of antibiotics, and the U.S. is currently reviewing the practice. The strategic issue facing U.S. pork producers is whether another food safety dispute with the EU is worthwhile. This paper evaluates the economic impact of such a ban in the U.S. The analysis uses a set of technical assumptions derived from the experience of a similar ban in Sweden and finds such a ban would increase production costs per head between $5.24 and $6.05; net profit would decline $0.79 per head. On the consumer side, the effects of a ban would raise the...

Response to an Asymmetric Demand for Attributes: An Application to the Market for Genetically Modified Crops AgEcon
Lence, Sergio H.; Hayes, Dermot J..
A framework is developed for examining the price and welfare effects of the introduction of genetically modified (GM) crops. In the short run, non-GM grain generally becomes another niche product. However, more profound market effects are observed under some reasonable parameterizations. In the long run, consumer and producer welfare are usually greater after the introduction of GM technology. Nevertheless, in all instances some consumers and some producers lose. When identity preservation is expensive and cost savings are relatively small, both producer and consumer welfare are lower after introducing GM technology. Interestingly, this outcome is obtained even though all agents are individually rational.
