Analysis

Abstract

Savage and Torgler find in their descriptive analysis that after a death commercial expeditions go on to record a successful climb in 80.6 per cent of cases while non-commercial expeditions are only successful 37.8 per cent of the time. This result is supporting in the multivariate analysis (likelihood of success is 2.5 times lower among non-commercial expeditions). Moreover, their results show that the introduction of the competing commercial expeditions has crowded out the pro-social behaviour in the non-commercial groups. The findings may also indicate that it is the Sherpa who are maintaining the pro-social behaviour, which is in line with much of the anecdotal evidence on Sherpa behaviour.
