PORT ELEVATOR CAPACITY AND NATIONAL AND WORLD GRAIN SHIPMENTS AgEcon
Barnett, Doug; Binkley, James K.; McCarl, Bruce A..
An analysis is conducted on the port component of the United States grain export system. A transshipment model is utilized which covers both United States internal and foreign shipments of corn, soybeans, and wheat during the four quarters of a year. The model suggests that there will be quarter to quarter constraints on port capacity but that annual capacity is adequate. Through sensitivity analysis a number of key factors were found which influence the adequacy of the current port system. Port adequacy is found to depend not as much on export market location as it does on domestic transportation rates and policies.

The Effect of Climate Change, CO2 Fertilization, and Crop Production Technology on Crop Yields and Its Economic Implications on Market Outcomes and Welfare Distribution AgEcon
Attavanich, Witsanu; McCarl, Bruce A..
Many studies have done econometric estimates of how climate alters crop yields and or land rents in an effort to gain information on potential effects of climate change. However, an important related factor, the atmospheric carbon dioxide (CO2) concentration, and in fact a driver of climate change is ignored. This means the prior econometric estimates are biased as they infer what will happen under climate change from observations in the recent past, but without consideration of CO2 effects. Furthermore although CO2 has been varying, it has proceeded at a very linear pace and cannot be disentangled from technological progress using historical crop yield data. This paper is designed to overcome this issue and estimate the consequences that CO2 has and...

How Climate Factors Influenced the Spatial Allocation of and Returns to Texas Cattle Breeds AgEcon
Zhang, Yuquan W.; Hagerman, Amy D.; McCarl, Bruce A..
A multivariate binary choice model is used to examine the climate effects on cattle breed selection across Texas counties. Angus, Brangus, and Brahman are considered in the model. Results suggest that it is more efficient to estimate the binary choice equations jointly than separately. Counties having higher summer temperatures are more likely to choose Brahman and warmer winters increase the likelihood of adopting Brangus and Brahman. Angus price imposes positive effects on both Angus and Brangus. In general, the marginal probability of selecting Angus is much higher than that of Brangus or Brahman.

ECONOMIC AND HYDROLOGIC IMPLICATIONS OF SUSPENDING IRRIGATION IN DRY YEARS AgEcon
Keplinger, Keith O.; McCarl, Bruce A.; Chowdhury, Manzoor E.; Lacewell, Ronald D..
A dry year irrigation suspension has been proposed as a way of reallocating water when aquifer levels are low for the Texas Edwards Aquifer. Under this program, farmers would be paid to suspend irrigation to allow more spring flow or nonagricultural pumping. When irrigation is suspended in the east, springflow response is markedly larger than when suspended in the western portions of the aquifer. Most acreage participates when a $90 per acre payment is offered before the cropping season. Considerably higher payments are needed and less water saved for a suspension program instituted during the cropping season.

THE ECONOMIC CONSEQUENCES OF ENSO EVENTS: THE 1997-98 EL NINO AND THE 1998-99 LA NINA AgEcon
Adams, Richard M.; Chen, Chi-Chung; McCarl, Bruce A.; Weiher, Rodney.
Climate is the primary determinant of agricultural productivity. In many parts of the world, including the United States, one can trace much of the year-to-year variations in climate to the El Nino-Southern Oscillation phenomenon. In 1997-98 the world experienced a severe El event and this is being flowed by a strong 1998-99 La Nina. The work underlying this develops estimates of the economic consequences of these events on U.S. agriculture. Both phases result in economic damages -- a $1.5 to $1.7 billion loss for the El Nino and a $2.2 to $6.5 billion for La Nina. The major conclusion is that ENSO events do impose costs on agriculture and consumers.

Rapid Effective Trace-Back Capability Value in Reducing the Cost of a Foot and Mouth Disease Event AgEcon
Hagerman, Amy D.; Looney, J. Chris; McCarl, Bruce A.; Anderson, David P.; Ward, Michael P..
This study evaluates how the availability of animal tracing affects the cost of a hypothetical Foot and Mouth Disease (FMD) outbreak in the Texas High Plains using alternative tracing scenarios. To accomplish this objective, the AusSpread epidemic disease spread model (Ward et al., 2006) is used to simulate a High Plains FMD outbreak under different animal tracing possibilities. A simple economic costing module (Elbakidze, 2008) is used to determine the savings in terms of animal disease mitigation costs from rapid, effective trace-back. The savings from increased traceability are then be compared to the cost of a functional National Animal Identification System (NAIS). Initial results indicate that rapid, effective tracing reduces the overall cost of...

MATHEMATICAL PROGRAMMING FOR RESOURCE POLICY APPRAISAL UNDER MULTIPLE OBJECTIVES AgEcon
McCarl, Bruce A..
Mathematical programming is one technique that can be used for resource policy appraisal. Multiple objectives are usually involved in resource policy considerations. This paper discusses issues regarding the use of mathematical programming techniques for the multiobjective resource policy arena. Theoretical models are introduced with a separation called for between producer response models and policy maker models due to a disparity of objectives. The paper draws on the literature citing cases where producer level models have been utilized to simulate the policy outcome implications of alternative policies.

STRATEGIC AGRIBUSINESS OPERATION REALIGNMENT IN THE TEXAS PRISON SYSTEM AgEcon
McCarl, Bruce A.; Rister, M. Edward; Ward, Ruby A.; Long, Charles R.; McCorkle, Dean A.; Ziari, Houshmand A.; Conner, J. Richard; Sturdivant, Allen W.; Thompson, Troy N..
Mathematical programming-based systems analysis is used to examine the consequences of alternative operation configuration for the agricultural operations within the Texas Department of Criminal Justice. Continuation versus elimination of the total operation as well as individual operating departments are considered. Methodology includes a firm systems operation model combined with capital budgeting and an integer programming based investment model. Results indicate the resources realize a positive return as a whole, but some enterprises are not using resources profitably. The integer investment model is found to be superior for investigating whether to continue multiple interrelated enterprises.

A Spatial Equilibrium Model of the Impact of Bio-Fuels Energy Policy on Grain Transportation Flows AgEcon
Ahmedov, Zafarbek; Power, Gabriel J.; Vedenov, Dmitry V.; Fuller, Stephen W.; McCarl, Bruce A.; Vadali, Sharada.
Traffic flows in the U.S. have been affected by the substantial increase and, as of January 2009, decrease in biofuel production and use. This paper considers a framework to study the effect on grain transportation flows of the 2005 Energy Act and subsequent legislation, which mandated higher production levels of biofuels, e.g. ethanol and biodiesels. Future research will incorporate changes due to the recent economic slowdown.

IMPACTS OF INCORPORATING LAND EXCHANGES BETWEEN FORESTRY AND AGRICULTURE IN SECTOR MODELS AgEcon
Alig, Ralph J.; Adams, Darius M.; McCarl, Bruce A..
The forest and agriculture sectors are linked by having a portion of their land bases suitable for use in either sector. A substantial part of the southern land base is suitable for either forestry or agriculture use, with most of forestation on U.S. agriculture land in the South. We examine how land exchanges between forestry and agriculture are influenced by specific federal conservation and farm support policies, including changes in the Conservation Reserve Program. Reallocation of land is a significant part of the sectors' responses to the policies, along with intensification of timber management on existing southern forests.

Animal Disease Related Pre-event Investment and Post-event Compensation: A Multi-agent Problem AgEcon
Jin, Yanhong H.; McCarl, Bruce A..
We employ a game-theoretic principal agent framework to analyze the individual farmer and governmental behavior pre- and post-animal disease outbreak. We examine the gap between the privately optimal and socially optimal levels of ex ante biosecurity investment and then investigate how a well-designed differentiated compensation scheme can close this gap. Our results also show that the privately optimal investment is generally lower than the first best socially optimal level, and a well-designed differentiated compensation scheme conditional on ex ante biosecurity investment can induce private preventive investment at least greater than the second best socially optimal level when the government face constraints, or even increase approaching the first best...

AN ECONOMIC, HYDROLOGIC, AND ENVIRONMENTAL ASSESSMENT OF WATER MANAGEMENT ALTERNATIVE PLANS FOR THE SOUTH CENTRAL TEXAS REGION AgEcon
Gillig, Dhazn; McCarl, Bruce A.; Boadu, Frederick O..
Regional water scarcity has motivated the South Central Texas Regional Water Planning Group to actively develop water management plans to address long-/short-term regional water needs. This study, therefore, develops an integrated Edwards Aquifer groundwater and river system simulation model to determine the "best" choice of regional water management plans using mixed-integer linear programming. The economic, hydrologic, and environmental consequences of the "best" choice of regional and other water management plans and options are evaluated and compared. Results indicate a tradeoff between the economic and environmental benefits. A slight decrease in economic benefit results in a substantial increase in environmental benefit.

Inter-Temporal Investment in Climate Change Adaptation and Mitigation AgEcon
Wang, Weiwei; McCarl, Bruce A..
Currently, different dimensions of mitigation strategies have been investigated in policy analysis. However, ambitious mitigation action aiming at reducing future climate change will not prevent much climate change before mid-century. Short-term and medium-term temperature as well as associated damages cannot be avoided completely. Increasingly there appears to be recognition of the need to simultaneously implement adaptation and mitigation. However, the optimal combination between adaptation and mitigation that can best address climate change over time is still an open question. Literature base is rather small, yet very diverse and inconsistent in conclusions. In this paper, we do an exploration of the temporal optimal investment mix between adaptation...

PREDICTING THE IMPACT OF NEW CROPPING PRACTICES UPON SUBSISTENCE FARMING: A FARM LEVEL ANALYSIS IN BRAZIL AgEcon
Brandao, Elizabeth Santos; McCarl, Bruce A.; Schuh, G. Edward.
An analysis is done on the potential effects of several improved cropping practices in a subsistence agricultural farming system along with analyses of other development options. The farming system is modeled as a linear programming model. The problem involves mixture of perennials and annuals, sharecropping provisions and risk. The practices are found to have differential effects on the distribution of income between the landlords and tenants, marketable surplus and on farm employment.

Hurricanes and Possible Intensity Increases: Effects on and Reactions from U.S. Agriculture AgEcon
Chen, Chi-Chung; McCarl, Bruce A..
Hurricanes have caused substantial damage in parts of the U.S. Damages are increasing, perhaps as part of a natural cycle or perhaps in part related to global warming. This paper examines the economic damages that hurricanes cause to U.S. agriculture, estimates the increased damage from an increase in hurricane frequency/intensity, and examines the way that sectoral reactions reduce damages. The simulation results show that hurricanes and associated adjustments cause widespread damage and redistribute agricultural welfare. We find that crop mix shifts of vulnerable crops from stricken to nonstricken regions significantly mitigate hurricane damages.
