The income stabilisation tool (IST) is the latest tool proposed by the European Union (EU) to manage agricultural risks. It aims at stabilising farm income by compensating income losses. Using a discrete choice experiment, this paper investigates grapevine farmers’ acceptance of the IST in Croatia and tests whether behavioural factors such as risk preferences, probability weighting and subjective probabilities related to future farm income explain acceptance of this new tool. Results suggest that there is demand for the IST. Pessimistic farmers are more likely to participate in the IST than others, suggesting that subjective probabilities influence farmers’ decisions about agricultural risk management.
