A note on finite sample breakdown points of projection based multivariate location and scatter statistics

In this note, general results of finite sample breakdown point are obtained for two classes of projection based location and scatter statistics: the Stahel-Donoho statistics and the Maronna-Yohai statistics. It is shown that these projection based location and scatter statistics can achieve the maximum breakdown point of affine equivariant multivariate location and scatter statistics. General relationships between the finite sample breakdown point of these statistics and the uniform finite sample breakdown point of the sample median and a modified sample median absolute deviation are formally established.

No one left behind: how social distance affects life-saving decision making

Extant research on social distance and decision-making under risk has mostly focused on how people reach different decisions for themselves than others under the same circumstances. This research adds to this literature by studying how the social distance between the decision-maker and people in danger influences risk preference in life-saving domain. We found that decision-makers tend to be more risk-seeking when the lives of close others are at stake than distant others regardless of whether the situation is framed in terms of loss or gain. However, the effect of social distance on risk preference was eliminated when it was the responsibility of the decision-makers rather than the chance to pick the potential victims to save. By analyzing the shape of value function, we provided preliminary evidence for the hypothesis that decision-makers engage in feeling-based evaluation when close others’ lives are at stake but calculation-based evaluation when distant others’ lives are at stake, which could account for the effect of social distance on risk preference documented in this research. A final experiment yielded direct evidence that evaluation mode mediates the relationship between social distance and risk preference.
