COMPARATIVE ANALYSIS OF VALUE-ADDED AND TRADITIONAL MEASURES OF PERFORMANCE: AN EFFICIENCY SCORE APPROACH AgEcon
Acheampong, Yvonne J.; Wetzstein, Michael E..
Stochastic frontier analysis is employed for a comparison of value-added and traditional measures of performance. Results indicate value-added measures are not significantly different from traditional measures of performance and thus little if any information is gained by replacing traditional measures with value-added measures. However, value-added measures may be useful to managers for value creation decisions resulting in excess profits.

RATIONAL EXPECTATIONS ESTIMATION OF GEORGIA SOYBEAN ACREAGE RESPONSE AgEcon
Ahouissoussi, Nicolas B.C.; McIntosh, Christopher S.; Wetzstein, Michael E..
The general method of moments procedure is used for estimating a soybean acreage response function assuming the producers hold rational expectations. Results indicate that soybean, corn, and wheat futures prices, lagged acreage, and government programs are significant factors for determining soybean plantings. Implications of the results are that crop acreage selection by Georgia producers is not very responsive to demand shocks. Thus, producers in other regions are more likely to absorb impacts from these shocks on crop acreage selection.

Forecasting Irrigation Water Demand: A Case Study on the Flint River Basin in Georgia AgEcon
Banerjee, Swagata (Ban); Tareen, Irfan Y.; Gunter, Lewell F.; Bramblett, Jimmy; Wetzstein, Michael E..
Southeast drought conditions have accentuated the demand for irrigation in the face of restricted water supply. For allocating this supply, Georgia held an auction for withdrawing irrigated acreage. This auction withdrew 33,000 acres from irrigation, resulting in a physical estimate of a 399 acre-feet daily increase in water flow. The actual reduction is driven by crop distributional changes on the basis of economic substitution and expansion effects. In contrast to the physical estimates, an econometric model that considers these effects is developed. The differences between the physical and econometric models result in an increase in the estimate of water savings of around 19% to 24%.

CHARACTERISTICS OF AGRICULTURAL ECONOMICS UNDERGRADUATE ADVISING IN THE WESTERN REGION AgEcon
Broder, Josef M.; Wetzstein, Michael E..
The quality of faculty advising has been a source of concern among students and faculty. As an initial attempt at addressing these concerns this paper summarizes the results of a faculty advising study in undergraduate agricultural economics programs. Various advising program characteristics among western schools are discussed and contrasted to schools in other regions. Interregional and interdepartmental variation was found in advisor resource allocation, advising program implementation, rewards and priorities, and evaluations of advising quality. Despite larger enrollments, smaller advising budgets, less support and lower rewards for advising, schools in the West reported advising quality comparable if not superior to that in other regions.

Economic Comparisons of Alternative and Conventional Production Technologies for Eggplant in Southern Georgia AgEcon
Brunson, Kathryn E.; Stark, C. Robert, Jr.; Wetzstein, Michael E.; Phatak, Sharad C..
Environmental concerns about pesticide usage in traditional production systems are prompting vegetable producers to consider alternative systems. Research results from a multi-year study on eggplant in southern Georgia compare two alternative production technologies to the conventional rye cover crop technology. Alternative technologies utilize beneficial insect principles as substitutes for conventional pesticide controls. Using field data, eggplant production budgets are developed to generate net return estimates under each system. Cost reductions achieved by using alternative technologies are not sufficient to offset the reduced yields and returns generated from these technologies. Cash input requirements for alternative systems suggest potential for...

Feasible Fumigant-Herbicide System Alternatives to Methyl Bromide for Bell Pepper Producers AgEcon
Byrd, Mark M.; Escalante, Cesar L.; Fonsah, Esendugue Greg; Wetzstein, Michael E..
With the current methyl bromide (MeBr) system for producing Georgia’s peppers being phased out, alternative fumigant and herbicide systems for producers are analyzed. Using stochastic dominance analyses, two alternatives exceeding MeBr’s yield and financial efficiency were identified. A programming model, incorporating simulation-optimization techniques, generated optimal production and financial plans. Results indicate potential economic viability under alternative systems vis-à-vis the traditional MeBr production system. The Telone II and Chloropicrin combination with Metham potassium may offer a viable substitute for MeBr.

A Farm-level Approach to the Methyl Bromide Phase-out: Identifying Alternatives and Maximizing Net Worth Using Stochastic Dominance and Optimization Procedures. AgEcon
Byrd, Mark M.; Escalante, Cesar L.; Wetzstein, Michael E.; Fonsah, Esendugue Greg.
Alternative fumigant and herbicide systems for Georgia's pepper farms are analyzed relative to soon-to-be phased-out methyl bromide system. Stochastic dominance analyses identify two alternatives exceeding MeBr's yield and financial efficiency. A programming model using simulation-optimization techniques provides important implications on the pepper farms' economic viability under these alternative systems.

The Impact on Farm Profitability and Yield Efficiency of Bell Pepper Production of the Methyl Bromide Phase-Out Program in Georgia AgEcon
Byrd, Mark M.; Fonsah, Esendugue Greg; Escalante, Cesar L.; Wetzstein, Michael E..
The elimination of methyl bromide (MeBr) has been a hot topic for policymakers for more than a decade. As a result, of the Montreal Protocol on Substances that Deplete the Ozone Layer, signatory nations began implementing guidelines aimed at reducing or eliminating a variety of toxic substances, including MeBr, which has been identified as one of the toxic contributors to ozone depletion. In 1997 the Ninth Meeting of the Parties in Montreal recommended an accelerated phase-out schedule for MeBr. The accelerated phase-out program is a major concern to most U.S. farmers, and in particular to farmers in Georgia, where the product is used not only as an important soil fumigant but also to control both the yellow and purple nutsedge (Cyperus sp.). Furthermore,...

Assessing the Effects of Climate Change on Farm Production and Profitability: Dynamic Simulation Approach AgEcon
Cai, Ruohong; Bergstrom, John C.; Mullen, Jeffrey D.; Wetzstein, Michael E..
In this paper, a dynamic optimization model was developed to simulate how farm-level realized price and profitability respond to yield change which was induced by climate change. Producers' acreage response was included in the dynamic model considering crop rotation effect. In the crop rotation model, a modified Bellman equation was used to dynamically optimize the net present value of farm profit for a five-year interval. This simulation process was repeated through the year 2050. Then yield, price, and acreage response were compiled to generate realized profit. Results generally indicated that reduction in crop yields due to climate change results in reduced farm profitability for most of the states studied. Predicted climate change is more likely to...

A Dynamic Optimal Crop Rotation Model in Acreage Response AgEcon
Cai, Ruohong; Bergstrom, John C.; Mullen, Jeffrey D.; Wetzstein, Michael E..
This paper presents a dynamic crop rotation model that shows how crop yield and price volatility could impact crop mix and acreage response under crop rotation considerations. Specifically, a discrete Markov decision model is utilized to optimize producers’ crop rotation decision within a finite horizon. By maximizing net present value of expected current and future profits, a modified Bellman equation helps develop optimum planting decisions. This model is capable of simulating crop rotations with different lengths and structures. Specifically, the corn-soybeans rotations were simulated using the crop rotation model.

Principal Component Analysis of Crop Yield Response to Climate Change AgEcon
Cai, Ruohong; Bergstrom, John C.; Mullen, Jeffrey D.; Wetzstein, Michael E.; Shurley, W. Donald.
The objective of this study is to compare the effects of climate change on crop yields across different regions. A Principal Component Regression (PCR) model is developed to estimate the historical relationships between weather and crop yields for corn, soybeans, cotton, and peanuts for several northern and southern U.S. states. Climate change projection data from three climate models are applied to the estimated PCR model to forecast crop yield response. Instead of directly using weather variables as predictor variables, the PCR model uses weather indices transformed from original weather variables by the Principal Component Analysis (PCA) approach. A climate change impact index (CCII) is developed to compare climate change effects across different...

COOPERATIVE ANTITRUST MONOPOLIZATION AND THE THEORY OF CONTESTABLE MARKETS AgEcon
Centner, Terence J.; Wetzstein, Michael E..
The judiciary has relied on a firm's market share to evaluate the presence of monopoly power for a Sherman Act monopolization violation. However, an allegation that a firm's market share constitutes monopoly power may be refuted by evidence that there exists a contestable market. Contestable market theory shows that there is no monopoly power where there exists a threat of entry of other firms. This theory thereby offers agricultural cooperatives, which may have a large market share by reasons of the antitrust immunity provided by the Capper-Volstead Act, an argument to overcome allegations of a Sherman Act monopolization violation.

OBLIGATIONS AND PENALTIES UNDER LEMON LAWS: AUTOMOBILES VERSUS TRACTORS AgEcon
Centner, Terence J.; Wetzstein, Michael E..
Distinctive new provisions of tractor lemon laws which create obligations and provide penalties for defective self-propelled agricultural equipment are contrasted with provisions of automobile lemon laws. Lemon-law obligations involve both producers'’ guarantees to provide consumers with a serviceable vehicle and producers'’ promise to remedy defects. Due to fewer manufacturer obligations under the tractor lemon laws as opposed to automobile lemon laws, tractors may be expected to have more defects than automobiles. Yet the tractor lemon laws contain fewer penalties in the form of restitution remedies. The inconsistencies of these obligations and penalties suggest tractor laws may be inefficient.

AN ECONOMIC EVALUATION OF SOYBEAN STINK BUG CONTROL ALTERNATIVES FOR THE SOUTHEASTERN UNITED STATES AgEcon
Chyen, David; Wetzstein, Michael E.; McPherson, Robert M.; Givan, William D..
Methyl parathion or Penncap M (an encapsulated methyl parathion) are used extensively throughout the United States for controlling stink bug pests in soybeans, Glycine Max (L.) Merrill. However, this insecticide is highly toxic to mammals, birds, and non-target arthropods, and thus is less environmentally sound than other insecticides. For environmental and human health considerations, investigating alternative insecticides for control is desired. For this investigation, research based on field experimental data from Florida, Georgia, and Louisiana during the 1988 and 1989 growing seasons were employed. Results indicate that alternative, currently available, and less toxic insecticides may reduce producer costs, increase yield, and improve soybean...
