Abstract We test and quantify the (in)stability of farmer risk preferences, accounting for both instability across elicitation methods over time. use repeated measurements ( N = 1530) with Swiss fruit grapevine producers 3 years, using different preference (domain‐specific self‐assessment incentivised lotteries). find that farmers' preferences change considerably when measured methods. For example, self‐reported findings from a Holt Laury lottery correlate only weakly (correlation...
Abstract The adoption of fungus-resistant grapevines may be a key strategy for substantially reducing fungicide use in pesticide-intensive viticulture. In representative survey conducted among 436 grapevine growers Switzerland, we elicited growers’ expected share land devoted to varieties ten years. More specifically, using regression analyses, explore the main predictors behind stated intentions. We find that one-third new plantings next decade will varieties. As result, years is 27.4%...
Abstract Grape production for wine making is of great economic and cultural importance in Europe, but heavily dependent on pesticides. Reducing pesticide use associated risks a policy goal several countries, particularly Europe. The most effective strategy to substantially reduce grape the planting fungus‐resistant varieties, which are less susceptible common fungal infections thus allow massive reduction treatments. However, their remains low. One possible reason may be that new varieties...
Calls for supporting sustainability through more and better research rest on an incomplete understanding of scientific evidence use. We argue that a variety barriers to transformative impact arises from diverse actor motivations within different stages abductively specify this in policy practice arenas three (truth-seeking, sense-making, utility-maximizing) five (evidence production, uptake, influence decisions, effects outcomes, feedback outcome evaluations). Our interdisciplinary synthesis...
Abstract We present a new approach to establish an empirical overview of farmers’ risk preferences and the characteristics associated with these preferences. rely on Individual Participant Data Meta-analysis whereby we identify studies eliciting through self-assessments Holt Laury lotteries, construct analyse unique dataset 5,157 farmers from 19 in 13 European countries. Our results reveal significant heterogeneity across elicitation methods, within studies, domains farm farmer...
Abstract Using fungus‐resistant grapevine varieties can reduce pesticide use substantially, while maintaining production quantity and quality. survey data from 775 producers in Switzerland, we investigate the adoption of especially analyze relevance marketing channels short supply chains. We find that 20.1% respondents but acreage is only 1.2%. Our results narrow down to a simple conclusion: less distant producer final consumer, more likely they varieties. For example, selling their wine...
Abstract Planting fungus‐resistant grapevines is an effective way to reduce pesticide use in grapevine production, but their uptake remains low. We explore whether providing personalized or general information on growers' of environmentally toxic fungicides changes planting intentions varieties (i.e., salience nudging), conducting a randomized experiment with 436 growers Switzerland. find no effect the intended plantation share varieties. However, exploratory analyses suggest that...
Abstract Explaining farmer decision making using cumulative prospect theory is of increasing importance. We present a systematic review on European farmers' preferences under the framework. identified 17 studies covering 2324 farmers from 12 countries. All report that (on average) are: (i) risk averse, (ii) loss and (iii) overweight small probabilities underweight large probabilities. However, there heterogeneity across within studies. These findings have implications for analysis design...
Abstract Pesticides are used to reduce yield losses and enhance the visual quality of products. However, pesticide use raises concerns due negative health environmental effects, hence ambitious policy goals for their reduction have been established. Reducing pesticides which mainly focus on products could be an efficient strategy contribute these goals, without reducing food production. role “cosmetic” is so far not well documented understood. Here, we quantify cosmetic influence supply...
Abstract This artefactual field experiment explores consumers’ willingness-to-pay (WTP) price premiums for fish products to avoid the risk and uncertainty of purchasing inauthentic produce. The influence subjective probabilistic beliefs, ambiguity preferences is investigated. Participants’ WTP elicited using experimental auctions, while behavioural factors are incentivised incentive-compatible methods: quadratic scoring rule multiple lists. Results show that consumers willing pay a premium...
Abstract Organic agricultural production is increasing globally and of high policy relevance, particularly in Europe. Various measures incentivize farmers to adopt organic practices, such as direct payments labelling. We here address a rarely considered aspect production, that not all producers Europe opt for labelling their products at the point sale. investigate discrepancy between Swiss viticulture. Out 115 grapevine growers who adhere principles 43.5% do use when marketing wines. find...
We present survey data from 436 grapevine growers across Switzerland and their production, pest, risk management decisions. The online was conducted in spring 2022 the three main official languages (German, French, Italian). used to obtain information on variety choice farm strategies, as well farmer, farm, spatial environmental characteristics. Moreover, we collected around fungus-resistant varieties such knowledge, attitudes, perceptions of these varieties. also elicited current...
We here present survey data from apple growers across Switzerland. Data 245 was collected, using an online in French and German 2022. The sampled represent 24.4% total land under apples. Apple production is one of the most economically relevant pesticide intensive crops. Hence, focus on growers' pest management decisions marketing strategies. Survey contains details agronomic practices such as grown cultivars, against fungi, insects, weeds, well use for cosmetic purposes. Moreover, we...
