The Internet may reduce constraints on a farmer's ability to receive and manage information, regardless of where the farm is located or when the information is used. Using a count data estimation procedure, this study attempts to examine the key farm, operator, regional, and household characteristics that influence the number of Internet applications used by farm households. Findings indicate that educational level of the farm operator, farm size, farm diversification, off-farm income, off-farm investments, and regional location of the farm have a significant impact on the number of Internet applications used.

The competitive structure of U.S. agricultural exports is examined using a model of exporter behavior based on pricing decisions across destination markets. Market power is revealed in the adjustment patterns of export prices in response to exchange rate movements. The results reject the hypothesis that the export pricing decisions by U.S. firms are consistent with price discrimination across destination markets for cotton, corn, and soybeans. The strongest evidence against the competitive market structure is obtained for international trade in wheat, where results indicate that the two largest importers (Soviet Union and PRC) may exert market power to obtain lower prices.

Coastal coral reefs, especially in the Florida Keys, are declining at a disturbing rate. Marine ecologists and reef scientists have emphasized the importance of establishing nonmarket values of coral reefs to assess the cost effectiveness of coral reef management and remediation programs. The purpose of this paper is to develop a travel cost-contingent valuation model of demand for trips to the Florida Keys focusing on willingness to pay (WTP) to preserve the current water quality and health of the coral reefs. The stated and revealed preference models allow the marginal valuation of recreationists to adjust depending on current and planned trip commitments in valuing nonmarginal policy changes in recreational opportunities. The integrated model incorporates key factors for establishing baseline amenity values for tourist dive sites, including perceptions of reef quality and dive conditions, the role of substitute sites, and the quality and availability of tourist facilities and recreation opportunities. The travel cost and WTP model differ in identifying critical variables and provide insight into the adjustment of trip decisions across alternative destination sites and the valuation of trips. In contrast to the travel cost model, a measure of the availability of substitute sites and total recreation activities does not have a significant impact on WTP valuations reported by snorkelers. Snorkelers engage in a relatively focused set of activities, suggesting that these recreationists may not shift expenditures to other sites or other recreation activities in the Florida Keys when confronted with increased access costs for the snorkeling experience.

Organic farmers make system-level crop protection decisions that combine complementary insect, disease, nematode, and weed management strategies. Data from a 1997 national survey of U.S. organic farmers were used in a multivariate count data model to identify the farm and regional factors influencing the adoption of practices across the linked pest management categories. The results show that weed management requires the greatest management effort by organic farmers. More intensive information-seeking and on-farm experimentation, higher educational attainment, and intensity of commitment to organic farming are positively related to the number of weed control strategies adopted. Predictions of adoption based on this model and customized to farm and region specifications will give information providers lead time to develop technical support for reduced chemical pest management systems.

Although the organic produce industry is growing dramatically, little is known about market structure. We estimate a system of reduced-form equations to evaluate supply and demand factors that influence equilibrium farm price and quantity in wholesale markets for organic broccoli, carrots, and lettuce. In the long run, demand factors dominate supply factors. Reduced wholesaling costs, increased margins by which organic wholesale price exceeds nonorganic price, and higher consumer income stimulate both farm price and output. Increasing the nonorganic farm price decreases equilibrium quantity of organics. Market expansion strategies should target consumers and wholesalers. Copyright 1996, Oxford University Press.

We study the determinants of somatic cell count (SCC) for fluid milk among U.S. dairies. We synthesize much of the work that has been done to model SCC economically in order to identify the potential impacts of buyer-imposed penalties and incentives within the supply chain. Additionally we estimate quantile regression for count data to measure impacts specifically for those operations with the highest SCC and to account for the statistical properties of the data. Premiums in particular have the potential to reduce SCC considerably where it is currently the highest. We draw implications for profitability in relation to SCC reduction.
