Overview of the presentation
• Risk paradigms • Risk and agriculture• Research on individual risk behaviour
– Risk attitude– Risk perception
• First Conclusions• A basic model for individual risk behaviour• Building further on the model (participatory approach)• Discussion & Questions
2
Risk paradigms
• Risk is about uncertainty and consequences
• Different views on risk– Constructivism and Risk: Risk is a social
construct inseparable from social and cultural processes.
– Real Risk, risk is objectively measurable– Subjective interpretation, risk is objectively
measurable however personal interpretation
3
Risk and agriculture
4
• Climate – Caused by: storms, hail, rain, floods, droughts,
diseases – Effects: Yield risks and price risk
• Policy – Regulation– Cap transforms
• Market – Internationalisation of markets– Increased price volatility: both input as output
prices
Research on risk behaviour
• Most common determinant on individual risk behaviour is risk attitude:
5
Most measures derived from expected utility:
• Risk Attitude• Relative Risk Attitude• Perceived Risk Attitude
Research on risk behaviour
• Most common determinant on individual risk behaviour is risk attitude:– Attitude derived from gamble experiments– Attitude seen as stable personality trait– No determinants for risk behaviour other than attitude– Behaviour optimalization given risk attitude
• However– Risk attitude is context specific– Risk perception should be taken into account– Risk attitude is manegable and should be optimalised given
a wanted behaviour– Integrated model by Pablo and Sitkin
6
Current research on perception:• Psychometric Paradigm• Cultural Theory• Social Amplification of risk
Important message: Risk perception is influenced by more than just an imperfect knowledge transfer from real risk information
Some conclusions
• When investigating individual risk behaviour:– See risk attitude as a context specific and
a manageable trait in order to optimalize behaviour
– Take risk perception influenced by social and cultural determinants into account together with risk attitude.
7
An example
• A day at the horse races:– Observation: Gamblers that lose during the day in the
end of the day start betting on long shots.– Explanation: Not risk attitude changes but the
perception of the gamblers on who the winning horses are.
• Feedbacks: – To: Attitude and Perception – To: knowledge on the real risk– Risk management

Information transfer of real risk
Perceived Risk
Real Risk
Perceived risk more than information transfer of the real risk:
• Social and cultural factors• Personality / Motivation• Habbits• Perceived Behavioural Control

Building further on the model
• Research is needed to build on this model:– Using a participatory approach actively involving farmers in
building on the model– Integrating qualitative and quantitative research
