Performance. Performance was operationalized through the share price at the end of
the simulation. Share price was given in Euros and was automatically calculated by the
simulation. The simulation also automatically calculated the team position in their
group ranging from first to eighth. We operationalized performance by recoding the
share price on 1 to 8 points-scale through the percentile values – we asked for the cut
points for eight equal groups. We created a new variable based on the values of the
eight groups, which was used in mediation analyses. The lowest share prices
correspond to lower values and the highest share prices correspond to higher values.
Our performance measure was discussed and constructed on the basis of
recommendations of the developers of the Global Management Challengew.
