Rift Valley Fever: An Economic Assessment of Agricultural and Human Vulnerability AgEcon
Hughes-Fraire, Randi; Hagerman, Amy D.; McCarl, Bruce A.; Gaff, Holly.
This research focused on the assessment of the U.S. agricultural sector and human vulnerability to a Rift Valley Fever (RVF) outbreak and the implications of a select set of alternative disease control strategies. Livestock impact assessment is done by using an integrated epidemic/economic model to examine the extent of RVF spread in the Southeast Texas livestock population and its consequences plus the outcome of implementing two different control strategies: emergency vaccination and larvicide vector control separately plus when they are used simultaneously. Human impact assessment utilized an inferential procedure, which comprises of a cost of illness calculation to assess the dollar cost of human illnesses and deaths, as well as a Disability Adjusted...

Economic Potential of Biomass-Based Fuels for Greenhouse Gas Emission Mitigation AgEcon
Schneider, Uwe A.; McCarl, Bruce A..
Use of biofuels diminishes fossil fuel combustion, thereby also reducing net greenhouse gas emissions. However, subsidies are needed to make agricultural biofuel production economically feasible. To explore the economic potential of biofuels in a greenhouse gas mitigation market, we incorporate data on production and biofuel processing for the designated energy crops—switchgrass, hybrid poplar, and willow—in a U.S. Agricultural Sector Model, along with data on traditional crop-livestock production and processing, and afforestation of cropland. Net emission coefficients on all included agricultural practices are estimated through crop growth simulation models or are taken from the literature. We simulate potential emission mitigation policies or markets...

THE VALUE OF ENSO INFORMATION TO AGRICULTURE: CONSIDERATION OF EVENT STRENGTH AND TRADE AgEcon
Chen, Chi-Chung; McCarl, Bruce A..
The agricultural value of El Nino-Southern Oscillation (ENSO) phase knowledge is measured in a value-of-information framework using economic models. We examine the value of considering the full distribution of ENSO phase strength effects as opposed to average ENSO phase strength effects, as well as the implications of considering ENSO impacts on the rest of the world (ROW). A stochastic U.S. agricultural sector model linked with a global trade model is used to assess the value of ENSO phase information. When the full distribution of ENSO phase strength is considered, the value of phase information increases twofold with respect to the average ENSO effects.

UNCERTAIN YIELDS IN SECTORAL WELFARE ANALYSIS: AN APPLICATION TO GLOBAL WARMING AgEcon
Lambert, David K.; McCarl, Bruce A.; He, Quifen; Kaylen, Michael S.; Rosenthal, Wesley; Chang, Ching-Cheng; Nayda, W.I..
Agriculture operates in an uncertain environment. Yields, prices, and resource usage can change dramatically from year to year. However, most analyses of the agricultural sector, at least those using mathematical programming methods, assume decision making is based on average yields, ignoring yield variability. This study examines how explicit consideration of stochastic yield outcomes influence a sector analysis. We develop a model that can be used for stochastic sector analysis. We extend the risk framework developed by Hazell and others to incorporate discrete yield outcomes as well as consumption activities dependent upon yield outcomes. An empirical application addresses a comparison between sector analysis with and without considerations of the...

The Effect of Climate Change over Agricultural Factor Productivity: Some Econometric Considerations AgEcon
McCarl, Bruce A.; Villavicencio, Xavier; Wu, Ximing.
This paper examines the role that climate change might be playing in the declining returns to agricultural research. For this purpose, we estimate a cross-section time-series model of agricultural total factor productivity for the U.S. states over the period 1970–1999, with the inclusion of climatic variables, and controlling for non stationarity of the data. Our findings suggest that after controlling for climatic variables and non stationarity, the effect of Public Agricultural Research Capital over Total Factor Productivity is reduced.

Does Negative Information Always Hurt Meat Demand? An Examination of Avian Influenza Information Impacts on U.S. AgEcon
Mu, Jianhong H.; McCarl, Bruce A..
Consumers’ consumption patterns could be affected by food safety information, however, it is more important to consider where the food safety issue occurs. If the food safety issue happens in other countries, in other words, it outbreaks out of the target market, negative information may be beneficial; in contrast, if the food safety issue occurs within the market, results may consistent with previous studies. Based on this assumption, this paper reinvestigates the impacts of AI media coverage and BSE cases on the demand of meat in U.S. market. Estimated results provide supports for our assumption, i.e., AI information has positive effect on poultry and turkey demands in short term, and BSE affect beef demand negatively.

Influences of Permanence on the Comparative Value of Biological Sequestration versus Emissions Offsets AgEcon
McCarl, Bruce A.; Murray, Brian C.; Schneider, Uwe A..
We use a net present value framework to examine the impact of non-permanence on the economics of land-based biological carbon sequestration. Contingent on assumptions about discount rates, management, and carbon prices trajectories, and payment contract design, we find the adjusted value of carbon sequestration relative to permanently available emission offsets to be between 38 and 55 percent for agricultural soil offsets and between 51 and 99 percent for afforestation offsets. Simulations with an Agricultural Sector Model show the empirical effect of sequestration value discounts on the total potential of U.S. agricultural sinks to mitigate greenhouse gas emissions within a multistrategy setting.

Should We Consider the Co-Benefits of Agricultural GHG Offsets? AgEcon
Elbakidze, Levan; McCarl, Bruce A..
Water quality and other co-benefits arise from greenhouse gas reduction efforts in agriculture, but there are tradeoffs with energy sector emissions. Greenhouse gas reductions by power plants also improve human health. Policy based on balancing benefits and costs must account for the co-effects in both the agriculture and energy sectors.

VALIDATION OF LINEAR PROGRAMMING MODELS AgEcon
McCarl, Bruce A.; Apland, Jeffrey.
Systematic approaches to validation of linear programming models are discussed for prescriptive and predictive applications to economic problems. Specific references are made to a general linear programming formulation, however, the approaches are applicable to mathematical programming applications in general. Detailed procedures are outlined for validating various aspects of model performance given complete or partial sets of observed, real world values of variables. Alternative evaluation criteria are presented along with procedures for correcting validation problems.

BIOPHYSICAL SIMULATION IN SUPPORT OF CROP PRODUCTION DECISIONS: A CASE STUDY IN THE BLACKLANDS REGION OF TEXAS AgEcon
Dillon, Carl R.; Mjelde, James W.; McCarl, Bruce A..
Economic feasibility of Texas Blacklands corn production in relation to sorghum, wheat, and cotton is studied. Biophysical simulation generated yield data are integrated with an economic decision model using quadratic programming. Given the various scenarios analyzed, corn is economically feasible for the Blacklands. A crop mix of half corn and half cotton production is selected under risk neutrality with wheat entering if risk aversion is present. Corn and grain sorghum production are highly substitutable. Profit effects attributed to changing corn planting dates are more pronounced than profit changes resulting from altering corn population or maturity class.

CLIMATE CHANGE INFLUENCES ON THE RISK OF AVIAN INFLUENZA OUTBREAKS AND ASSOCIATED ECONOMIC LOSS AgEcon
Mu, Jianhong H.; McCarl, Bruce A.; Wu, Ximing; Gan, Li.
This paper examines the effect that climate has on Avian Influenza outbreak probability. The statistical analysis shows across a broad region the probability of an outbreak declines by 0.22% when the temperature rises 1 Celsius degree and increases by 0.34% when precipitation increases by 1millimeter. These results indicate that the realized climate change of the last 20 years not only has been a factor behind recent HPAI outbreaks, but that climate change is likely to play an even greater role in the future. The statistical results indicate that overall, the risk of an AI outbreak has been increased by 51% under past climate change and 3-4% under future climate change. An economic evaluation shows the increased probability of outbreaks has caused...

Global Implications of U.S. Biofuels Policies in an Integrated Partial and General Equilibrium Framework AgEcon
Birur, Dileep K.; Beach, Robert H.; Hertel, Thomas W.; McCarl, Bruce A..
With the increasing research interests in biofuels, global implications of biofuels production have been generally examined either in a partial equilibrium (PE) or general equilibrium (GE) frameworks. Though both of these approaches have unique strengths, they also suffer from many limitations due to complexity of addressing all the relevant aspects of biofuels. In this paper we have exploited the strengths of both PE and GE approaches for analyzing the economic and environmental implications of the U.S. policies on corn-ethanol and biodiesel production. In this study, we utilize the Forest and Agricultural Sector Optimization Model (FASOMGHG: Adams et al. 1996, 2005; Beach et al. 2009), a non-linear programming, PE model for the United States. We also use...

Greenhouse Gas Mitigation through Energy Crops in the United States with Implications for Asian-Pacific Countries AgEcon
Schneider, Uwe A.; McCarl, Bruce A..
Agriculture-based biofuels have the potential to replace fossil fuels, thereby offsetting greenhouse gas emissions. We estimate emission abatement supply curves from energy crops switchgrass, hybrid poplar, and willow under a wide range of sectorwide greenhouse gas emission reduction incentives in U.S. agriculture. The Agricultural Sector Model employed captures market interactions of biofuel production with traditional agricultural production and with alternative emission mitigation strategies. U.S. results suggest an increasing importance of biomass-based electricity for carbon mitigation incentives above an economic threshold of $50 per ton. At incentive levels of $170 per ton and higher, emission offsets from energy crops provide the highest net...

The Lifecycle Carbon Footprint, Bioenergy and Leakage: Empirical Investigations AgEcon
McCarl, Bruce A..
Agriculture may help mitigate climate change risks by reducing net greenhouse gas (GHG) emissions (McCarl and Schneider, 2000). One way of doing this is that agriculture may provide substitute products that can replace fossil fuel intensive products or production processes. One such possibility involves providing feedstocks for conversion into consumable forms of energy, where the feedstocks are agriculturally produced products, crop residues, wastes, or processing byproducts. Such items may be used to generate bioenergy encompassing the possibilities where feedstocks are used: • to fuel electrical power plants; • as inputs into processes making liquid transportation fuels e.g., ethanol or biodiesel. Employing agriculturally produced products in such a way...
