A QUALITATIVE CHOICE ANALYSIS OF FACTORS INFLUENCING POST-CRP LAND USE DECISIONS AgEcon
Johnson, Phillip N.; Misra, Sukant K.; Ervin, R. Terry.
The future use of Conservation Reserve Program (CRP) lands is an important agricultural policy issue. To examine the effects of factors that influence landowners' post-contract use of CRP lands, a survey of Texas High Plains CRP contract holders was conducted in 1992. This study analyzes the results of the survey using a qualitative choice model. It was found that the presence of a livestock enterprise in the current contract holder's operation increases the probability of these acres remaining in the established cover. Contract holders who value the commodity base have an increased probability of returning their acres to crop production.

AN EVALUATION OF POST CONSERVATION RESERVE PROGRAM ALTERNATIVES IN THE TEXAS HIGH PLAINS AgEcon
Johnson, Phillip N.; Segarra, Eduardo.
Four policy alternatives for CRP lands upon expiration of the current contracts in Hale county, Texas are evaluated using chance-constrained programming. It was found that if CRP contracts are extended at the current average rental rate, 40 percent of the current enrollment would be expected to return to crop production, while 66 percent would return to crop production if the program were eliminated. The results also indicate that the marginal value of CRP payments to producers is lower than the marginal value of deficiency payments.

ANNUAL REPORT RESEARCH PROGRAM 2003/2004 AgEcon
Ethridge, Don E.; Segarra, Eduardo; Johnson, Phillip N.; Malaga, Jaime E.; Rejesus, Roderick M..
The department began producing formal reports of research activities in 1995/96 in conjunction with the establishment of the Cotton Economics Research Program; reports on Cotton Economics Research have been done annually since then. As our research programs expanded and diversified, we initiated a separate Departmental Research Report in 1998/99. With this annual report we are combining all research reporting into the single report, with more compartmentalization of research programs. This report highlights research activities in the Department of Agricultural and Applied Economics during fiscal year 2003/04. The overall program has been characterized by its flexibility in addressing varied issues of economic significance and is applied in nature,...

Aquifer Depletion and the Cost of Water Conservation: The Southern High Plains of Texas Case AgEcon
Wheeler, Erin A.; Segarra, Eduardo; Johnson, Phillip N.; Willis, David B.; Johnson, Jeffrey W..
Irrigated agriculture has played a vital role in the development and growth of the Great Plains Region of the United States. The primary source of water for irrigation in this region is the Ogallala Aquifer. The Southern portion of the Ogallala Aquifer is considered exhaustible due to the low level of recharge relative to the quantities of water pumped. Analysis and evaluation of water conservation policies which could extend the economic life of the Ogallala Aquifer in the Southern High Plains of Texas and Eastern New Mexico, and which could contribute to maintaining the viability of the regional economy is important. This study evaluates the impacts of water conservation policies which limit drawdown of the Ogallala Aquifer. County level dynamic...

Carbon Footprint: A New Farm Management Consideration in the Southern High Plains AgEcon
Weinheimer, Justin; Rajan, Nithya; Johnson, Phillip N.; Maas, Stephan.
As concerns continue to mount regarding man induced impacts to the global climate, the SHPT region could be faced with a unique scenario in which the net carbon balance should be considered in the producer’s enterprise selection and production systems. Currently, the SHPT produces nearly one third of the U.S. cotton crop. Under a potential cap and trade system the challenge for the agricultural industry in the SHPT may be how to sustain the region’s economic base and production capabilities. Thus, the objective of this study was to measure the net carbon relationships between irrigated cotton and irrigated corn production systems on the SHPT using data from the Texas Alliance for Water Conservation (TAWC, 2009). Due to the unique management and production...

Cotton Farmers' Technical Efficiency: Stochastic and Nonstochastic Production Function Approaches AgEcon
Chakraborty, Kalyan; Misra, Sukant K.; Johnson, Phillip N..
Technical efficiency for cotton growers is examined using both stochastic (SFA) and nonstochastic (DEA) production function approaches. The empirical application uses farm-level data from four counties in west Texas. While efficiency scores for the individual farms differed between SFA and DEA, the mean efficiency scores are invariant of the method of estimation under the assumption of constant returns to scale. On average, irrigated farms are 80% and nonirrigated farms are 70% efficient. Findings show that in Texas, the irrigated farms, on average, could reduce their expenditures on other inputs by 10%, and the nonirrigated farms could reduce their expenditures on machinery and labor by 12% and 13%, respectively, while producing the same level of output.

Efficient Refuge policies for Bt cotton in India AgEcon
Singla, Rohit; Johnson, Phillip N.; Misra, Sukant K..
This study examined the efficient refuge policies for Bt cotton for three cotton growing regions in India. This was accomplished by developing a single-pest, dual-toxin biological model simulating bollworm resistance to the Bt toxin and synthetic pyrethroids, followed by formulating profit functions for Bt and non-Bt cotton for a representative producer in each region. Profits received in subsequent periods were considered in the regulatory model in order to choose a refuge constraint (static problem) or a sequence of refuge policies (dynamic problem) for each region that maximize discounted profits received over 15 years, subject to various economic and biological constraints. Dynamic solutions for the regulatory problem were derived for each region using...

Groundwater Policy Research: Collaboration with Groundwater Conservation Districts in Texas AgEcon
Johnson, Jeffrey W.; Johnson, Phillip N.; Guerrero, Bridget L.; Weinheimer, Justin; Amosson, Stephen H.; Almas, Lal K.; Golden, Bill B.; Wheeler-Cook, Erin.
The unique nature of the Ogallala Aquifer presents interesting and confounding problems for water policymakers who are coping with changing groundwater rules in Texas. The purpose of this article is to link previous efforts in water policy research for the Ogallala Aquifer in Texas with current collaborations that are ongoing with regional water planners. A chronological progression of economic water modeling efforts for the region is reviewed. The results of two recent collaborative studies are presented that provide estimates of impacts of alternative policies on groundwater saturated thickness, water use, net farm income, and regional economic activities.

Impact of efficient refuge policies for Bt cotton in India on world cotton trade AgEcon
Singla, Rohit; Johnson, Phillip N.; Misra, Sukant K..
India is a major cotton producing country in the world along with the U.S. and China. A change in the supply of and demand for cotton in the Indian market has the potential to have an impact on world cotton trade. This study evaluates the implications of efficient Bt cotton refuge policies in India on world and U.S. cotton markets. It can be hypothesized that increased refuge requirements for Bt cotton varieties in India could decrease the world supply of cotton because of the lower yield potential of non-Bt cotton varieties planted in refuges. A decrease in world cotton supply could potentially raise world cotton prices, ceteris paribus. This study conceptualizes the impact of efficient refuges in India on world cotton markets by using a partial...

Understanding Acre for Cotton AgEcon
Pan, Suwen; Hudson, Darren; Ethridge, Don E.; Mutuc, Maria Erlinda M.; Fadiga, Mohamadou L.; Johnson, Phillip N..
The Food, Conservation, and Energy Act of 2008 was passed into law on May 22, 2008 with veto override votes in the House of Representatives and the Senate (House 2008). A difference between the 2002 and the 2008 bills is the newly instituted revenue-based counter-cyclical program called the Average Crop Revenue Election (ACRE) program available beginning crop year 2009. The ACRE program is offered as an alternative to the counter-cyclical payment (CCP) program that was in place during the 2002-2008 period. Beginning with the 2009 crop year, producers will have the option to enroll their farm in either the CCP program or the ACRE program. If ACRE is elected, producers cannot change program participation for the duration of the 2008 farm bill (ERS 2008)....
