USE OF PRINCIPAL COMPONENT ATTRACTIVENESS INDEXES IN RECREATION DEMAND FUNCTIONS AgEcon
Wetzstein, Michael E.; Green, Richard D..
The method of principal components is used to construct attractiveness indexes for existing and proposed wilderness areas in California. Rankings of areas based on this procedure are compared with those based on size and the subjective attractiveness index developed by the Forest Service. The derived indexes are then used to develop alternative opportunities variables that appear as explanatory variables in outdoor recreation demand functions. Results indicate that substantially better explanatory capacity can be achieved over alternative measures by including a competitive factor in the demand functions. The paper concludes by considering the substitution effects of introducing new wilderness areas into the system.

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.

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.

CLASSIFICATION OF RISK PREFERENCES WITH ELICITED UTILITY DATA: DOES FUNCTIONAL FORM MATTER? AgEcon
Musser, Wesley N.; Wetzstein, Michael E.; Reece, Susan Y.; Musser, Lynn M.; Varca, Philip E.; Chou, Charlene C.J..
Recently, several problems with elicited utility functions have emerged. This paper concerns a fundamental problem in risk preference classification with elicited data. For the sample in this research, different functional forms resulted in reversals in preference classifications. This paper suggests that preference classifications must be interpreted with caution.

AN EVALUATION OF INTEGRATED PEST MANAGEMENT WITH HETEROGENEOUS PARTICIPATION AgEcon
Wetzstein, Michael E.; Musser, Wesley N.; Linder, David K.; Douce, G. Keith.
Principal component analysis in employed to develop indices that distinguish between participants and nonparticipants in Integrated Pest Management (IPM) programs. Results of incorporating these indices into yield, net return, and production cost functions for cotton producers indicate that both yield and costs increase as the degree of producer participation in IPM increases. Although these results are inconsistent with previous research, they are consistent with the theoretical relationship between IPM and conventional input usage.

RETURNS TO SCALE AND SIZE IN AGRICULTURAL ECONOMICS AgEcon
McClelland, John W.; Wetzstein, Michael E.; Musser, Wesley N..
Differences between the concepts of returns to size and returns to scale are systematically reexamined in this paper. Specifically, the relationship between returns to scale and size are examined through the use of the envelope theorem. A major conclusion of the paper is that the level of abstraction in applying a cost function derived from a homothetic technology within a relevant range of the expansion path may not be severe when compared to the theoretical, estimative, and computational advantages of these technologies.

EVALUATION OF VARIOUS PEST-MANAGEMENT CHARACTERISTICS AgEcon
Smith, G. Scott; Wetzstein, Michael E.; Douce, G. Keith.
Considering pest management in terms of a set of technology characteristics allows an investigation of various pest-management characteristics and how they relate to a total pest-management package. Employing restricted and unrestricted least squares in this investigation indicates the unique impact individual pest-management characteristics exert on net returns. A Stein-rule estimator is also employed in assessing this impact.

EFFICIENCY CRITERIA AND RISK AVERSION: AN EMPIRICAL EVALUATION AgEcon
Wetzstein, Michael E.; Szmedra, Philip I.; McClendon, Ronald W.; Edwards, David M..
A conceptual link among mean-variance (EV), stochastic dominance (SD), and mean-risk (ET), and Gini mean difference (EG) is established for determining risk efficient decision sets. The theoretical relations among the various efficiency criteria are then empirically demonstrated with a soybean and wheat double-crop simulation model. Empirical results associated with extended Gini mean difference (EEG) and extended mean-absolute Gini (EET) for risk analysis are encouraging.

A CASE STUDY OF TIMELINESS IN THE SELECTION OF RISK-EFFICIENT MACHINERY COMPLEMENTS AgEcon
Wetzstein, Michael E.; Musser, Wesley N.; McClendon, Ronald W.; Edwards, David M..
The importance of timeliness is investigated in the selection of machinery complements for double-crop wheat and soybean production in the southeastern coastal plain. An intertemporal stochastic simulation model was developed to generate probability distributions that were evaluated with stochastic dominance analysis. This research investigated the importance of intertemporal production linkages and adequate soil moisture on machinery selection. Failure to include these dimensions can result in erroneous machinery choices.

ECONOMIC RISK EFFICIENCY OF BOLL WEEVIL ERADICATION AgEcon
Szmedra, Philip I.; McClendon, Ronald W.; Wetzstein, Michael E..
The purpose of this study was to determine the economic risk efficiency of implementing a boll weevil (Anthonomus grandis [Boheman]) eradication (BWE) program in cotton (Gossypium hirsutum L.) producing regions of the Mississippi Delta. Alternative producer pest management practices and program cost sharing were incorporated into a biophysical cotton simulation model. Participation in a BWE program along with strict adherence to Cooperative Extension Service pest management guidelines proved to be the risk efficient practice.

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...

ECONOMIC RETURNS TO THE BOLL WEEVIL ERADICATION PROGRAM AgEcon
Ahouissoussi, Nicolas B.C.; Wetzstein, Michael E.; Duffy, Patricia A..
The economic viability of the Boll Weevil Eradication program in Alabama, Florida, and Georgia is assessed based on a five-year survey of producers. Results indicate the program increases yield 100 pounds per acre. This implies a 19 percent internal rate of return for producers over a ten year period.

Effects of the Boll Weevil Eradication Program on Alabama Cotton Farms AgEcon
Duffy, Patricia A.; Cain, Danny L.; Young, George J.; Wetzstein, Michael E..
Five-year, 0-1 mixed integer programming models of two representative Alabama farms were developed for analyzing the effects of the Boll Weevil Eradication (BWE) program on farm program participation and crop-mix decisions by Alabama cotton farmers. In previous research the BWE program was found to increase yields by approximately 100 pounds per acre in Georgia and southern Alabama where the program has been in effect for several years. In this study, these increased yields are shown to be an important factor contributing to the expanded cotton acreage in southern Alabama. For northern Alabama, gains to producers are also possible, but not to the extent realized in the southern part of the state.

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.

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...
