Variation in Risk Seeking Behavior in a Natural Experiment on Large Losses Induced by a Natural Disaster

This study explores people's risk attitudes after having suffered large real- world losses following a natural disaster. Using the margins of the 2011 Australian foods (Brisbane) as a natural experimental setting, we find that homeowners who were victims of the foods and face large losses in property values are 50% more likely to opt for a risky gamble – a scratch card giving a small chance of a large gain ($500,000) - than for a sure amount of comparable value ($10). This finding is consistent with prospect theory predictions of the adoption of a risk- seeking attitude after a loss.
