The Estonian Citizens' Assembly (ECA) was initiated in late 2012 as a direct consequence of a legitimacy crisis of Estonian political parties and representative institutions. The spark igniting this crisis was the unraveling of a scheme of illegal party financing. The response from governmental institutions took the form of a democratic innovation involving public crowd-sourcing and deliberative mini-publics. This study reports on a survey among the participants in the online crowd-sourcing process of the ECA (n = 847). The study examines how this democratic innovation influenced participants' social and political trust as well as the impact of participants' predispositions and level of satisfaction with the ECA on changes in trust. We find that participants that had positive predispositions and who were satisfied with the ECA were more likely to gain trust. Furthermore, we also find that the participants, in general, became more distrustful of political institutions, while their participation fostered increased social trust. This outcome differs from the intentions of the Estonian institutions which organized the ECA and sheds new light on the role of democratic innovations in the context of legitimacy crises. This is an important step forward in the scholarly understanding of the relationship between democratic innovation and trust.

Although democratic innovations (DIs) are spread all over the world, there is little research on the institutional outcomes of implementing such innovations in governmental organisations. To remedy this, it is important to focus on cases where DIs have been implemented and formally connected to the policymaking process over a longer period. Reykjavik provides such a case. Drawing on observations and interviews with key stakeholders over a period of three years, this study analyses how the institutional logic of DIs influenced the local government in Reykjavik. The study presents two conclusions: First, it is clear that one equilibrium (representative democracy) has not been replaced by another (participatory democracy). Second, there is no peaceful co-existence between the two, but instead the outcome is an organisation in ‘a state of flux’. There are several factors contributing to this outcome, but three stand out: a populist power-shift, dissatisfaction with theworking of the implemented DIs and deliberative ambiguity. In the final part of the article, the institutional outcome is discussed in relation to overall consequences for the political system.
