Risk
When the probability of an event is 100%, is it still risk?
Risico and behavior
After assessing the risks, how do you proceed?
Research Tversky / Kahneman (1979) Own experiment
Survey students period 1 - 2010/11
Situation 1:
100% certainty 3.000 EUR profit
vs
80% certainty of 4.000 and 20% certainty of zero profit
Situation 2:
100% certainty 3.000 EUR loss
vs
80% certainty of 4.000 and 20% certainty of zero loss

Legal:
Contracts
SLAs
Etc.
Economical:
Financial instruments (derivatives, insurance)
Internal control instruments
Etc.
Management:
Quality systems
HRM instruments: competencies, experience, motivation
