Increasingly cities around the
world are introducing multichannel democratic innovations that integrate
multiple engagement processes. This article offers a first overview of this
emerging phenomenon by exploring three families of multi-channel innovations:
participatory budgetings, citizens’ assemblies, and citizen relations
management platforms. The authors introduce a series of definitions to identify
some of the building blocks of these complex democratic innovations’. The paper
uses this framework to explore the opportunities and challenges of integrating
multiple channels of engagement, and to describe the most common integration
mechanisms employed by these families of innovations: managed competition,
regulation and isolation. This paper constitutes a first step in a new research
agenda that goes beyond the variety of labels of democratic innovations and
investigates how these institutions can be modeled as different combinations of
a common set of building blocks.
