ℝà-transfer and Harsanyi NTU values: Individual rationality, stability and degenerate solutions

The authors investigate the properties of individual rationality and stability for Harsanyi and λ-transfer value for non-transferable utility games, paying particular attention to degenerate solutions. They stress some situations in which the two values behave differently. The authors also give a general existence theorem for Harsanyi value, which does not require the assumption of games being compactly generated.
