Proportionality of Willingness to Pay to Small Risk Changes – The Impact of Attitudinal Factors in Scope Tests

Sensitivity (proportionality) of willingness to pay to (small) risk changes is often used as a criterion to test for valid measures of economic preferences. In a contingent valuation (CV) study conducted in Austria in February 2005 1,005 respondents were asked their willingness to pay (WTP) for preventing an increase in risk by 1/42,500 and 3/42,500, respectively. WTP for the higher risk variation is significantly higher than WTP for the lower risk change. We find evidence that those respondents who have personal experience with avalanches combine the information about future risk increase, provided in the survey, with the observed number of mortal avalanche accidents in the past. The proportionality of WTP holds if such prior experiences are taken into account and the influence of attitudinal factors in scope tests are controlled for.Contingent Valuation, Willingness to Pay, Scope Test, Sensitivity of WTP

Dying in an Avalanche: Current Risks and Valuation

This paper examines the influence of implicit information associated with the occurrence of avalanches on willingness to pay (WTP) values for a risk prevention of dying in an avalanche. We present results of a contingent valuation (CV) study carried out in Austria in two different periods (fall 2004 and winter 2005). The comparison of WTP results between the two waves allows the identification whether the immediate occurrence of avalanches and their attendant deathly accidents affect individual risk evaluations. Surprisingly, individuals state a lower WTP in winter although avalanche accidents are predominant at that time. Personal responsibility of risk exposure and its associated voluntariness are main reasons for the decrease in WTP over time. Preferences for alternative protective measures (e.g. against car accidents or food poisoning) also lead to a decrease of WTP while a higher risk perception and personal experience with avalanches show a positive influence. We conclude that the change in WTP across seasons is not arbitrary but can be explained by specific risk characteristics. It follows that WTP is more robust as previously assumed and therefore represents a proper measure for the elicitation of individual risk reduction preferences.Contingent valuation, willingness to pay, risk prevention, risk perception

On Intrinsic Magnetic Moments In Black Hole Candidates

In previous work we found that many of the spectral properties of low mass x-ray binaries, including galactic black hole candidates could be explained by a magnetic propeller model that requires an intrinsically magnetized central object. Here we describe how the Einstein field equations of General Relativity and equipartition magnetic fields permit the existence of highly red shifted, extremely long lived, collapsing, radiating objects. We examine the properties of these collapsed objects and discuss characteristics that might lead to their confirmation as the source of black hole candidate phenomena.Comment: 4 pages, emulateapj, accepted for ApJ Letters, October 20, 200
