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. |

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. |

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. |

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. |

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. |

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. |

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... |
