A revealed-preference–based approach is proposed for valuation of the environmental and human impacts of pesticides. It is assumed that farmers reveal their willingness to pay for improved pesticide safety by selecting a specific product out of the set of available alternatives based on their costs, effectiveness, and safety. The approach is applied to estimate the welfare impact of changed patterns of herbicide use on Roundup Ready soybeans. The results indicate that farmers associate positive values with safety improvements. The aggregate welfare impact of the reduced risk for the U.S. soybean farmers was estimated to be $90.3 million in 2001.

Herbicide Use

Forty growers in 4 major cotton-growing regions in Australia were surveyed in 2003 to investigate how the adoption of glyphosate-tolerant cotton (Roundup Ready) had influenced herbicide use, weed management techniques, and whether changes to the weed spectrum could be identified. The 10 most common weeds reported on cotton fields were the same in glyphosate-tolerant and conventional fields in this survey. Herbicide use patterns were altered by the adoption of glyphosate-tolerant cotton with up to 6 times more glyphosate usage, but 21% fewer growers applying pre-emergence herbicides in glyphosate-tolerant fields. Other weed control practices such as the use of post-emergence herbicides, inter-row cultivation and hand hoeing were only reduced marginally. However, growers indicated that management practices are likely to change over time, especially with the introduction of enhanced glyphosate tolerance technology (Roundup Ready Flex), and anticipate a 32% decrease in the number of growers using alternative weed management practices. To date, management practices other than glyphosate use have not changed markedly in glyphosate-tolerant cotton indicating a conservative approach by growers adopting this technology and reflecting the narrow window of herbicide application. The range of weed control options still being employed in glyphosate-tolerant cotton would not increase the risk of glyphosate resistance development.

Revealed Preference Approach

Abstract We propose a novel approach to model joint consumption decisions of individuals who care for each other. The model encompasses a continuum of group consumption models situated between the fully co-operative model and the non-cooperative model without caring. We also define a measure for the degree of intragroup cooperation that quantifies how close the observed group behaviour is to fully co-operative behaviour. Following a revealed preference approach, we derive testable implications of the model for empirical data. We use our model to analyse decisions made by children in an experimental setting.
