AN EVALUATION OF CONSUMER PESTICIDE RESIDUE CONCERNS AND RISK INFORMATION SOURCES
Marginal probability effects of demographic variables on consumer concerns about pesticide residues were assessed as well as the likelihood of consumer beliefs given different channels of information on produce safety and risks. This was done using maximum likelihood estimation (MLE) of ordered logit models. The empirical results showed that pesticide residue concern levels appeared to be lower for more highly educated and high income households. Safety information from the academic community was found to have the highest likelihood of acceptance by consumers.Risk and Uncertainty,

THE SINGLE INDEX MARKET MODEL IN AGRICULTURE
This study illustrates the differences in empirical results due to data measurements and estimating procedures when applying the single index market model in agriculture. Gross and net return betas along with systematic and unsystematic risk proportions are estimated and found to be different. The stochastic coefficients model is used to show the difference in beta-risk estimates compared with the traditional fixed coefficients OLS procedure. A third estimating technique, weighted least squares/Prais Winsten method, is also proposed.Research Methods/ Statistical Methods,
THE FINANCIAL FEASIBILITY OF ESTABLISHING A FRESH PRODUCE PACKING HOUSE IN JORDAN
Historically, Jordan's traditional markets for fresh produce have been the Persian Gulf countries. However, these exports have declined in recent years and new markets in Europe have been tapped. One of the main constraints to expanding the European market is the lack of quality-oriented packing houses in Jordan. This study considers the feasibility of a vegetable packing house designed to meet the quality requirements of the European market. The overall objective is to evaluate the economic viability of packing and transporting various fresh produce items to the European market. Specifically, four transportation scenarios were evaluated using a comprehensive firm-level, dynamic and stochastic, multiple-year, capital budgeting computer simulation model. Simulation provides a very flexible technique that can easily incorporate risk and uncertainty into the investment decision-making process. The results show that the medium sized vegetable packing house is viable when serving the European markets. Also, the economic performance of the packing house improved when shipping by refrigerated truck. Furthermore, the stabilizing effect of land transport was captured in the much lower variability in the expected returns.Agribusiness,
