Effects of risk
immediate/delayed direct/indirect material/psychological non-/voluntary personal/environmental single/recurring
Risk characteristics
Controllability Equitability Perceived threat Reversability Threat to values Trustworthiness of those in charge of managing risks
Risk decisions and decision making
Choosing amongst alternative courses of action
Risk are associated with the outcomes of the courses of action
Courses of action need to be described in an order of desirability
Definition of risk
Risks threaten things that we value
DEcision under risk
Choosing courses of action to reduce the threat posed by risks depend on:
- the options available
- the outcomes of those options
- beliefs about the certainty of those options
What are the perspectives on risk?
Normative
Descriptive
Prescriptive
What is normative perspective on risk?
Rational decision-making Making correct choices IF: -the DM is fully informed -the DM is in touch with values -the DM follows consistent rules
Risk according to the normative perspective
Risk exists where there is more than one possible outcome of a decision
Risk is described as a probability (%), which is assigned to outcomes of decisions
What is risk analysis?
Risk analysis establishes probabilities through various means determines the benefit of each outcome ranks the outcomes from ”best” to ”worst”
Some key points on risk analysis
The usefulness of historical risk data
Common concepts in risk analysis:
Risk or uncertainty: Risk = objective measures of outcomes
Uncertainty = subjective measures of outcomes
The descriptive perspective
The study of practical decision making
Actual choices
Imperfect
Heuristic decision rules
One source of heuristics?
Bounded rationality
- approximate optimization
- satisficing
Prescriptive perspective
About being as rational as possibleusing management tools ”risk management”
Bridging the gap between normative and descriptive, in this course: The finance of innovation, risks
Risk decisions
Making decisions about risk in practice
Basic elements:
-(available) options, outcomes, uncertainties
-set in a social context
-framed in a language highlighting certain aspects of the decision
