Johansson-Stenman, Olof, Fredrik Carlsson and Peter Martinsson. 2004. “Is Transport Safety More Valuable in the Air?.” Journal of Risk and Uncertainty 28:2: 147-163.
Using a contingent valuation survey, people’s willingness to pay for a given risk reduction is found to be much larger, consistently more than two times as large, when traveling by air compared to by taxi.
Follow-up questions revealed that an important reason for this discrepancy is that many experience a higher mental suffering from flying, and that they are willing to pay to reduce this suffering. It was also consistently found that people are willing to pay more for a certain risk reduction if the original price was higher. Policy implications are discussed.
