A THEORETICAL DEVELOPMENT AND EMPIRICAL TEST ON THE CONVERGENCE OF AGRICULTURAL PRODUCTIVITY IN THE USA AgEcon
Paudel, Krishna P.; Sambidi, Pramod R.; Sulgham, Anil K..
This study explores the evidence of convergence in the U.S agriculture sector by using the state level total factor productivity (TFP) data. The empirical investigation conducted in this study does not find any evidence of convergence while looking at the state level TFP. However, there seems to be some support for convergence at the regional level. Parametric and nonparametric models indicate significant role of human capital in explaining the regional discrepancies in agriculture productivity across states.

A Watershed-Based Economic Model of Alternative Management Practices in Southern Agricultural Systems AgEcon
Paudel, Krishna P.; Hite, Diane; Intarapapong, Walaiporn; Susanto, Dwi.
We investigated the environmental impacts of alternative cultural practices within a watershed under different water quality standards. We used experimental data on nutrient runoff to determine the optimal amount of broiler litter application in hay production in Louisiana. To compensate for the lack of experimental data, we used biophysical simulation models to find the optimal combination of agricultural best-management practices in a watershed in Mississippi. The results indicated that stricter environmental standards lower total profit potential and litter utilization.

Agricultural Productivity Convergence: Myth or Reality? AgEcon
Poudel, Biswo N.; Paudel, Krishna P.; Zilberman, David.
We tested agricultural productivity convergence in the United States using the state level total factor productivity data and utilizing new estimation and cluster identification methods to identify convergence in the data. The empirical investigation did not indicate any evidence of agricultural total factor productivity (TFP) convergence at the state level. However, we found the evidence of TFP convergence at the regional level for some regions/clusters.

An Analysis of Rank Ordered Data AgEcon
Paudel, Krishna P.; Poudel, Biswo N.; Dunn, Michael A.; Pandit, Mahesh.
Many methods are available to analyze rank ordered data. We used a spectral density method to analyze Formosan subterranean termite control options ranked by Louisiana homeowners. Respondents are asked to rank termite control options from the most preferred to the least preferred option. Spectral analysis results indicated that the most preferred termite control choice is a relatively cheap ($0.13 per square foot) option of liquid treatment.

AN APPLICATION OF THE PHOSPHORUS CONSISTENT RULE FOR ENVIRONMENTALLY ACCEPTABLE COST-EFFICIENT MANAGEMENT OF BROILER LITTER IN CROP PRODUCTION AgEcon
Paudel, Krishna P.; Limaye, Ashutosh S; Adhikari, Murali; Martin, Neil R., Jr..
We calculated the profitability of using broiler litter as a source of plant nutrients using the phosphorus consistent litter application rule. The cost saving by using litter is 37% over the use of chemical fertilizer alone to meet the nutrient needs of major crops grown in Alabama. In the optimal solution, only a few routes of all the possible routes developed were used for inter- and intra- county litter hauling. If litter is not adopted as the sole source of crop nutrients, the best environmental policy may be to pair the phosphorus consistent rule with taxes, marketable permits, and subsidies.

AN EVALUATION OF AN ECONOMIC STRATEGY FOR PREVENTING WATER POLLUTION USING A PHOSPHORUS CONSISTENT TRANSPORTATION MODEL: A CASE OF BROILER LITTER MANAGEMENT AgEcon
Adhikari, Murali; Paudel, Krishna P.; Martin, Neil R., Jr..
We calculated the profitability of using broiler litter as a source of plant nutrient using a phosphorus consistent litter application rule. We found that each ton of litter can be transferred cost effectively up to 164 miles from the production facilities. The minimum cost phosphorus consistent transportation model developed to meet the nutrient needs of 29 counties in North Alabama revealed that not all the litter can be utilized in the region. The total cost for nutrient supply increased when transportation of litter from heavily surplus counties were prioritized. The effect of chemical fertilizer price change minimally affected the total litter use.

An Evaluation of Factors Affecting the Choice of Coastal Recreational Activities AgEcon
Paudel, Krishna P.; Caffey, Rex H.; Devkota, Nirmala.
A visitor’s decision to use a particular recreational site is influenced by the individual’s taste as well as the characteristics of the site. For this reason, improved knowledge of the visitors’ interests and factors influencing their choices are vital for both planning and policy formulations in coastal development. This study examines visitor characteristics and desired site specific characteristics in order to determine the factors affecting use of the Louisiana coast for specific recreational purposes. We use a multinomial logit model and internet survey data to evaluate the factors affecting individuals’ decisions to visit coastal Louisiana for a specific use. Results suggest that the major variables affecting the choice of coastal recreational...

Analysis of ranked ordered data when there are complete and partial ranking AgEcon
Pandit, Mahesh; Paudel, Krishna P.; Dunn, Michael A..
Many methods are available to analyze rank ordered data. We used a spectral density analysis to identify most preferred options of Formosan Subterranean Termites (FST) control as ranked by Louisiana homeowners. Respondents are asked to rank four termite control methods form the most preferred option to the least preferred option. Spectral analysis of both complete and partial ranked data indicates that the most preferred termite control choice is a relatively cheap ($0.13 per square foot) option of a Liquid treatment.

ASSESSING THE IMPACTS OF GLOBAL WARMING IN THE SOUTHEAST US AGRICULTURE USING OPTIMIZATION AND ECONOMIC FORECASTING PROCEDURE AgEcon
Paudel, Krishna P.; Hatch, L. Upton.
We used a memory shortening transformation method to forecast the future prices of the seven selected commodities in the Southeast USA. These forecasted prices were used to find the optimal crop selection in a model farm in a representative county of each of the ten states in the Southeast US under three likely climate change scenarios. It is found that the Hadley climate change scenario may be benign compared to Hot and Very Hot Scenarios.

Awareness of and Application to the Environmental Quality Incentives Program By Cow–Calf Producers AgEcon
Obubuafo, Joyce; Gillespie, Jeffrey M.; Paudel, Krishna P.; Kim, Seon-Ae.
This study uses a bivariate probit model with partial observability to examine Louisiana beef producers’ awareness of the Environmental Quality Incentives Program (EQIP) and how awareness translates to application to the program. Results indicate that awareness of and application to the EQIP depend on portion of income derived from off-farm sources, extent of previous best management practice adoption at one’s own expense, household income, farmed land that is highly erodible, contact with Natural Resource Conservation Service and extension service personnel, and producer age.

BROILER PRODUCERS’ WILLINGNESS TO PAY TO MANAGE NUTRIENT POLLUTION AgEcon
Devkota, Nirmala; Paudel, Krishna P.; Parajuli, Shanta.
Economic incentives or disincentives play a major role on encouraging producers to implement environmentally benign production practices. We evaluated producers’ willingness to pay (WTP) value to represent the level of disincentives that motivate farmers to mitigate nutrient pollution. The result obtained by using ordered response model showed that farm size, farm income, and land available to spread litter are major variables that determine the producers’ WTP.

Decision to Adopt and Exit Best Management Practices by Dairy Farmers AgEcon
Hall, Larry M.; Paudel, Krishna P.; Gauthier, Wayne M.; Westra, John V..
Dairy farmers in Louisiana were surveyed to find out the factors leading these farmers to terminate best management practices. Results indicated that only few farmers have exited the practices once they adopt those. However, the longevity of best management practices adoption can be increased by emphasizing on education and targeting to operators who have already been in dairy practices for a longer time period.
