Using a nested bivariate panel probit model, we quantify the perceived attribute values (PAV) that beef producers place on different information flows and alliance attributes. Our framework allows us to quantify the monetary value of individual rather than fixed sets of attributes. Results indicate that young producers are most likely to join an alliance, and high participation fees are a significant deterrent to joining an alliance. A PAV of $12.64/head is attached to an alliance that enforces restrictions on vaccinations and antibiotic use. For small producers, not having a required minimum number of animals has a PAV of $9.65/head.

Parallels are drawn between shortcomings and events that occurred in our western heritage with current issues facing agricultural economists. Challenges are made in relation to conflict of interest policies, external funding, cultivating connections with experts outside our discipline, and relevance of research priorities. Survey data on research priorities of upper administrators and faculty within colleges of agriculture are compared to those of Western Agricultural Economics Association members. Upper administrators from land grant colleges rank research focused in the area of competitiveness and profitability less than areas of water usage, food safety, renewable energy, global climate change, or sustainability.

Invasive insect species represent perhaps one of the most significant potential sources of economic risk to U.S. agricultural production. Private control of invasive insect species is likely to be insufficient due to negative externality and weaker-link public good problems. In this study, we compare a system of Pigouvian taxes with tradable permits for invasive species control. While the emissions control literature shows that taxes are preferred to permits under cost uncertainty, invasive-species control involves correlated cost and benefit uncertainty. Hence, we expect a quantity-based system to be preferred. Monte Carlo simulations of optimal steady-state outcomes confirm our expectations.

Classification and Regression Trees (CART), a computer intensive nonparametric classification method, was used to model weekly Los Angeles wholesale prices (1990-93) for twelve different melon types. CART explained more of the variation in melon prices than did an ordinary least squares (OLS) regression with dummy variables. Explanatory variables ranked as the most-to-least important by CART are as follows: week, type of melon, year, size, grade, and shipping container. The most notable price change occurs when prices fall after 13 May.

Marketing concepts associated with quality, location, and time are integrated into a complete model, revealing the linkages between market window approaches and hedonic analysis. An integrated hedonic price model for the U.S. apple industry was estimated. Results suggested that size, storage method, grade, and seasonality are the most important influences on the price of apples. Area of apple origin and variety were the least important influences on apple prices, with the exception of the Granny Smith variety.
