We develop a flexible model to examine competitive conditions in the food retailing industry based on the Box-Cox transformation of the demand and industry equilibrium conditions. The impact of key technological and market developments on shifts in the competitive index is examined. Adoption of optical scanning technology was positively related to the market power index but the index was stable and consistent with competitive conditions over the 1982-1992 period.

Improving Extension Effectiveness for Organic Clients: Current Status and Future Directions

Technical Efficiency of U.S. Organic Farmers: The Complementary Roles of Soil Management Techniques and Farm Experience

Responses from a national survey of U.S. organic farmers indicated dissatisfaction with the extension service. An ordered probit model was used to identify the factors influencing effectiveness ratings of extension advisors by farmers. Study findings show that part-time, higher income organic farmers who used a variety of highly rated private-sector information sources rated extension providers as more effective. Farmers in the Northeast and West regions rated extension usefulness more highly than in other regions. Not accounting for these demographic components in effectiveness ratings may result in under- or overestimation of results of organic-targeted extension programs. Extension agents can improve their usefulness to organic farmers by complementing...

ORGANIC PEST MANAGEMENT DECISIONS: A SYSTEMS APPROACH

Agricultural policymakers place increasing emphasis on developing efficiency measures for organic producers in order to evaluate regulatory strategies and evolving organic market conditions. We develop technical efficiency measures for U.S. organic farmers using a stochastic production frontier. Farm decisions about acquiring and managing organic soil materials from on-farm and local sources are incorporated into the technical efficiency measure. Productivity differences between newer entrants to organic farming and more experienced producers are estimated in order to isolate the impact of learning and management expertise on farm-level technical efficiency.

Organic farmers make system-level crop protection decisions that combine complementary insect, disease, nematode, and weed management strategies. Data from a national survey of U.S. organic farmers were used in a multivariate count data model to identify the farm and regional factors influencing the intensity of adoption across the linked pest management categories. The results showed that weed management is of greatest concern to organic farmers. More intensive information-seeking and on-farm experimentation, higher educational attainment, and intensity of commitment to organic farming were positively related to the number of weed control strategies adopted. Predictions of adoption intensity based on this model and customized to farm and region...

CERTIFICATION AND SUPPLY RESPONSE IN THE ORGANIC LETTUCE MARKET

ASSESSING ORGANIC PRODUCTION EFFICIENCY: A STOCHASTIC DISTANCE FUNCTION APPROACH

The impact of supply relationships and certification programs on the organic lettuce market is examined using an integrated partial adjustment and asymmetric supply response model. Costs associated with organic certification, production, and marketing have not restricted producers' abilities to respond to price signals. Organic growers allocate output between certified and noncertified markets in response to changing price premiums. Estimates of short-run supply elasticities indicate that organic lettuce growers are more responsive to price changes than producers of nonorganic lettuce. Long-run elasticity has increased since 1988, a change that coincides with the market entry of larger producers.

A stochastic distance function frontier was estimated using data from a national survey of organic farmers to evaluate the effect of farm-specific attributes on efficiency. Farm-specific and regional variables that shift efficiency were incorporated into the multioutput distance function, including organic farming experience, use of soil-improving inputs, and farmer involvement in research. Participation in research projects reduces the level of on-farm technical inefficiency with mean technical efficiency of participating farmers 25 percent higher than nonparticipating farmers. The results suggest that differences in productivity across organic farmers are closely linked to input use and observable management decisions.

Timely adoption of new varieties is critical to profitable peach production, and peach quality is a primary factor driving adoption. An adoption model for peach varieties is estimated, incorporating grower evaluations of peach quality. The model identifies the impact of farm characteristics such as the farmer's quality preferences, on-farm agronomic and orchard conditions, as well as geographic effects in Georgia peach-growing regions. The relative impact of the key external and internal peach quality attributes on adoption is assessed. Decisions on new varieties are influenced by the age distribution of the orchard, information which can be used in targeting new varieties to growers.

We investigate the objectives of agricultural bank managers and their impacts on bank efficiency. If managers are non-neutral toward risk, then banks may appear inefficient when they are not. We find non-neutrality toward risk and efficiency gains due to firm size, loan shares, asset shares, and share of market deposits.

PROMOTING FARM SAFETY WITH ECONOMIC AND MANAGERIAL INCENTIVES

Park, Timothy A..

Competition from new store formats including supercenters, warehouse clubs, and mass merchandisers has emerged as a major threat to traditional grocery chains. A primary objective of this paper is to understand how the store-level performance is related to the workforce composition of full-time and part-time employees chosen by the food retailer along with benefits and incentives provided to employees. The elasticity of complementarity for food retailers measures how changes in store size affect use of full-time and part-time employees. Larger store size increases the marginal value of labor, and firm hiring decisions shift to expanded use of part-time employees.

In the era of a global economy, farmers face increasing pressure in developing a portfolio of various marketing channels. However, the literature on direct marketing strategies has mainly focused on consumers. Using farm-level data this study investigates factors associated with the choice of three direct marketing strategies. We apply a selectivity based approach for the multinomial logit model to assess the relationship between the choice of direct sales marketing strategy on the financial performance of the business. Findings from this study suggest that obtaining an Internet connection and accessing the Internet for farm commerce increases the likelihood of using intermediated marketing outlets. Using the Internet for farm commerce and operating...

We develop measures of technical and allocative efficiency of producers in marketing certified organic products. A stochastic output distance frontier and the associated revenue share equations are estimated using comprehensive U.S. data on certified organic producers. Farm-level measures of technical efficiency are calculated and factors which enhance performance are identified. Factors that systematically influence allocative efficiency are assessed. The revenue mix of organic producers is systematically inefficient as both male and female producers rely too heavily on revenue from organic markets relative to conventional outlets.

This paper attempts to quantitatively measure the change in the productivity of Danish organic farming in recent years. Based on a translog production frontier framework the technical and scale efficiency on farm level is analysed by following a time trends as well as a general index model specification. We further try to analyse the significance of subsidies for promoting long term growth in organic production by estimating a bootstrapped bivariate probit model with respect to factors influencing the probability of organic market exit. The results revealed significant differencies in the organic farms' technical efficiencies, no significant total factor productivity growth and even a slightly negative rate of...

An indirect utility model is employed for measuring farmers willingness to voluntarily accept yield losses for a reduction in environmental risk by decreasing pesticide use. Results support the hypothesis that farmers have self-described risk perceptions that enable them to make assessments of risk-yield tradeoffs. Policies designed to encourage and assist farmers making voluntary pesticide reductions can result in environmental risk reduction.
