The sense of snow - Individuals' perception of fatal avalanche events

摘要

This empirical paper aims at examining individuals' risk perception in the context of an environmental disaster. Risk is defined as probability of dying in a snow avalanche. Risk perception is analyzed from two different perspectives: (i) individuals' estimate of the average avalanche risk and (ii) the perceived personal avalanche risk. The perception of personal risk is summarized in an ordered categorical variable, average risk perception is captured by a measurement previously used in risk communication that results in a continuous variable. The variation in risk perception observed is examined by using individual leisure activities (skiing) and the timing of the survey (fall vs. winter) as proxies for frequency, familiarity, controllability, voluntariness, and beneficiary of risk exposure and by including several individual specific characteristics such as age, gender, education, income. The results show that risk as well as individual specific characteristics are significant determinants of participants' perception of risk but their relevance differs depending on whether the focus is on perception of average risk or of personal risk.
