Focusing on two toy models, we discuss how such a suppression may arise in the context of open inflation models, in which inflation is preceded by false vacuum decay. Whilst one source of suppression is the fast rolling of the inflaton after the tunnelling event, we also see that effects from the tunnelling itself must be taken into account.
