Robustness of intermediate agreements for the discrete Raiffa solution

- A published axiomatization result for the discrete Raiffa solution R is shown to be false.
- Shortcomings and mistakes in the proof of that result are identified.
- A modified version of that result and a proof have been provided.
- The relation to the other published axiomatizations in the literature has been analyzed.

First via a counter example it is shown that Proposition 3 of Anbarci and Sun (2013) is false. Then a gap and a mistake in their proof are identified. Finally, a modified version of their Proposition 3 is stated and proved.
