  4. Problem statement Contamination of farmland Food safety? Health risks? Uncertainty? Soilremediation? Land userestrictions? “Impact soilpollution on farmlandvalues?” Cu Cd As Zn Summer school Choice experiments - Leuven (BE) – 3rd July 2013

  5. Problem statement Hedonicpricinganalysis (HP) Y: Farmland values X: Soil Cd concentrations Result No effect Robust • Y= α+ β1x1+ β2x2+ … + ε Summer school Choice experiments - Leuven (BE) – 3rd July 2013

  6. Problem statement Why? StatedPreference(DCE) Objective Circumventweaknesses HP Provide explanations Summer school Choice experiments - Leuven (BE) – 3rd July 2013

  7. Design Simulate land purchasedecision Select attribute(s) (levels) • Expert knowledge • Contact information • Co-operation Complementarity to HP Summer school Choice experiments - Leuven (BE) – 3rd July 2013

  8. Design Attribute levels Littlevariability Extra consequenceslimited Basedon HP dataset Summer school Choice experiments - Leuven (BE) – 3rd July 2013
