This paper considers a situation where a real risk exists that requires precautions, but the public mostly experiences the risk through infrequently occurring extreme events; this type of risk includes risk from climate change, international terrorism, natural calamities or financial crises. The analysis shows that if a risk-mitigating policy is based on the perceived riskiness of that risk, it will call for disproportionate responses (compared to what the real' risk suggests) by either under- or over-investing in risk-reducing policies, depending on the characteristics of the problem, implying significant volatility in the policy response. This type of response provides at least three challenges to society: policy cycles where implementation lags behind the actual change in risk, a lock-in to inefficient technologies and additional costs. Finally, this paper addresses the question of how the above-mentioned challenges can be managed through proper risk communication.
