4 Experiment description
Value elicited (verbal) | Value elicited | Decision problem | ||
---|---|---|---|---|
Part 0 | Explanation of case, ambiguity (uncertainty) context, alternatives, and test questions | |||
Part 1 | 1.1 | Loss \(L_{1}\), given: gain G = 60,000 EUR |
\(L_{1}\)
|
\(x_{0} \sim GL_{1}\)
|
1.2 | First positive outcome \(x_{1}^{ + }\) |
\(x_{1}^{ + }\)
|
\(Gx_{0} \sim x_{1}^{ + }\)
| |
1.3 | First negative outcome \(x_{1}^{ - }\) |
\(x_{1}^{ - }\)
|
\(L_{1} x_{0} \sim x_{1}^{ - }\)
| |
Part 2 | 2.1 | Loss \(L_{2}\), given: loss l = 9000 EUR |
\(L_{2}\)
|
\(lx_{0} \sim x_{1}^{ + } L_{2}\)
|
2.2 | Second to sixth positive outcome \(x_{j}^{ + } ;j \in \left\{ {2, \ldots ,6} \right\}\) |
\(x_{j}^{ + }\)
|
\(x_{j - 1}^{ + } l \sim x_{j}^{ + } L_{2}\)
| |
Part 3 | 3.1 | Gain \(G_{1}\), given: gain g = 9000 EUR |
\(G_{1}\)
|
\(gx_{0} \sim G_{1} x_{1}^{ - }\)
|
3.2 | Second to sixth negative outcome \(x_{j}^{ - } ;j \in \left\{ {2, \ldots ,6} \right\}\) |
\(x_{j}^{ - }\)
|
\(gx_{j - 1}^{ - } \sim G_{1} x_{j}^{ - }\)
| |
Part 4 | Fourth outcome \(x_{4}^{ + }\) (again, as control) |
\(x_{4}^{ + }\)
|
\(x_{3}^{ + } l \sim x_{4}^{ + } L_{2}\)
| |
Part 5 | Demographic questions | Gender, age, lectures taken,… |
