Abstract
We introduce two models for imprecise probabilities which generalise the Pari-Mutuel Model while retaining its simple structure. Their consistency properties are investigated, as well as their capability of formalising an assessor’s different attitudes. It turns out that one model is always coherent, while the other is (occasionally coherent but) generally only 2-coherent, and may elicit a conflicting attitude towards risk.

Notes
- 1.
It can be shown that a third, less relevant, submodel completes the family of NL models.
- 2.
When \(b=1,\,a=0\), \(\mu \) is a probability. We shall hereafter neglect this subcase.
- 3.
\(a+b>1\) in (k) could be relaxed to \(a+b\ge 1\), thus including the PMM as a special HB-PMM. We left out this case to focus on the ‘proper’ HB-PMMs.
