| Restrictions on the hyperbolic trigonometric (HT) transformation are imposed to guarantee that a probability density function is obtained from the maximum likelihood estimation. Performance of the restricted HT transformation using data generated from normal, beta, gamma, logistic, log-normal, Pareto, Weibull, order statistic, and bimodal populations is investigated via sampling experiments. Results suggest that the restricted HT transformaltion is sufficiently flexible to compete with the actual population distributions in most cases. Application of the restricted HT transformation is illustrated by characterizing uncertain net income per acre for community-supported agriculture farms in the northeastern United States. |

| The risk flexible production model developed by Just and Pope is estimated for the case of cotton in Californias San Joaquin Valley and the implications of the model for factor demand are examined. Results indicate risk-reducing roles for farm machinery, labor, and fertilizers in contrast to restrictions imposed by traditional stochastic production specifications. Qualitative assessment of estimated risk effects on factor employment under risk aversion are evaluated by comparison to the risk-neutral solution. |

| We show how an interseasonal pest control problem can be simplified to enable an intraseasonal model to be empirically applied, extending the range of application of the intraseasonal model. Three alternative economic thresholds are compared. The optimal solution requires repeated computations by the farmer to compute the profit maximizing dose, with a corresponding threshold, for each pest infestation. Two alternative decision rules require a single computation by the farmer for the threshold and dosage rate. An empirical illustration shows that, relative to the optimal solution which is computationally burdensome to the farmer, little net revenue is lost by using one of the thresholds based upon a simpler decision rule. |

| Due to agriculture's increasingly complex technical and economic environment, the diversity of information required for competitive and profitable farming is growing as never before. With constant and, in some cases, reduced resources for agricultural programs, Extension must exercise special care in prioritizing informational efforts to best meet farm-client needs and retain an important base of public support. This paper presents a method of identifying popular informational priorities in Agricultural Extension. The method is illustrated by application to dairy programming in Massachusetts. |

| The continued decline in both the number of and the acreage in small-scale farms and rural communities, as well as food safety and environmental concerns, has heightened interest in the community-supported agriculture (CSA) concept. Mean-variance, stochastic dominance, mean-Gini, and exponential utility/moment-generating function approaches to stochastic efficiency are employed to analyze three years of farm survey data on core management options for CSA farms. The core concept yields higher net income per acre than non-core management and, based on the stochastic efficiency analysis, should be regarded as the preferred management option for many CSA operators. |

| This article adds to the information base concerning the applicability of mean- Gini stochastic efficiency analysis in agriculture. The mean-Gini efficient set of decisions is characterized rigorously in terms of its corresponding absolute risk aversion. In an empirical analysis, the mean-Gini efficient set of decisions is derived for four studies from the literature and compared to the second degree stochastic dominance efficient set. An alternative quantitative measure of risk aversion is used to gain insight in a visceral sense to the risk preferences associated with mean-Gini efficient decisions. |

| Recent studies of capital budgeting procedures used by business executives suggest increasing use of present value methods. This study compares Massachusetts greenhouse business managers use of capital budgeting procedures to those of Fortune 1000 firms. Results indicate that different capital budgeting procedures are used and that the payback criterion remains the most popular for the farm firms studied. Some implications for Extension finance educators are drawn. |

| Prioritizing exotic or invasive pest threats in terms of agricultural, environmental, or human health damages is an important resource allocation issue for programs charged with preventing or responding to the entry of such organisms. Under extreme uncertainty, program managers may decide to research the severity of threats, develop prevention or control actions, and estimate cost-effectiveness in order to provide better information and more options when making decisions to choose strategies for specific pests. We examine decision rules based on the minimax and relative cost criteria in order to express a cautious approach for decisions regarding severe, irreversible consequences, discuss the strengths and weaknesses of these rules, examine the roles of... |
