Recent developments in the U.S. pecan industry appear to limit the utility of past research. The importance of pecan variety has emerged as an issue which could alter past results. The linear and double-log models previously fitted to all pecans (averaged) data may be too restrictive and hence, are less useful for variety-specific analysis. Past research also analyzed price turning points using nominal data. This study investigated functional form and data-averaging problems by fitting separate flexible Box-Cox price-dependent models for all-pecans and each variety of pecans (1970/71 -1988/89 deflated data). Results indicate: other nuts substitute for different pecan varieties, estimated all-pecans price flexibility is biased and clouds variety-specific... |

Arkansas ranks first in broiler production in the USA with more than a billion broiler and 1.5 million tons of litter produced in 1993. Transporting litter from western to eastern Arkansas can accomplish two goals: 1) avoid potential threat to clean water in western Arkansas and 2) can increase productivity of graded lands in the Delta. This paper examines the feasibility of litter transport from areas of high poultry concentrations to the Delta for use as a soil amendment. We establish the conditions for economical litter transport from source to destinations and determine the optimal rates of litter applications. The results suggest that it is economical to transport significant portions of litter. |

The growth of the poultry industry in Arkansas has exploded in the past decade. As a result, approximately 1.5 million tons of litter are produced every year. Concerns about possible contamination of ground and surface water from land applications of poultry litter have been raised. This paper compares four policy scenarios in terms of their efficiency and practicality to manage land applications of poultry litter. The results indicate that a litter tax per ton of litter applied could achieve the same level of litter control as that of a land tax on litter applications, but at a lower tax rate. |

A methodological approach to obtain bounds on the value of information based on an inexact representation of the decision makers utility function is presented. Stochastic dominance procedures are used to derive the bounds. These bounds provide more information than the single point estimates associated with traditional decision analysis approach to valuing information, in that classes of utility functions can be considered instead of one specific utility function. Empirical results for valuing seasonal climate forecasts illustrate that the type of management strategy given by the decision makers prior knowledge interacts with the decision makers risk preferences to determine the bounds. |

A microcomputer program to perform Generalized Stochastic Dominance (GSD), Quasi-Second Degree Dominance (SSD), and Quasi-First Degree Stochastic Dominance (FSD) is described. The program is designed to run on IBM-compatible personal computers with a Hercules or CGA graphics adapter. It is menu-driven and has options for GSD, quasi-FSD, quasi-SSD, graphics, and calculations of premiums associated with use of dominant distributions. |

The Pratt-Arrow measure of absolute risk aversion, as defined by r(x)=-un(x)/u1(x), is well known to be invariant to linear transformations. However, this invariance property applies with respect to transformations of u and not with respect to arbitrary rescalings of the outcome variables, x. The effects of this misunderstanding has led to ambiguity in classifying attitudes by risk aversion coefficients. It is shown that inappropriate rescalings of the outcome variable can lead to inaccurate rankings produced by generalized stochastic dominance. |
