In this article, we hence shed light on how these conflicting notions may be resolved and explore the potential of blockchain technology for dissolving the issue of trust in the sharing economy. By means of a dual literature review we find that 1) the conceptualization of trust differs substantially between the contexts of blockchain and the sharing economy, 2) blockchain technology is to some degree suitable to replace trust in platform providers, and that 3) trust-free systems are hardly transferable to sharing economy interactions and will crucially depend on the development of trusted interfaces for blockchain-based sharing economy ecosystems.

Participatory Budgeting has by now been widely discussed, often celebrated, and is now instituted in at least 1,500 cities worldwide. Some of its central features—its structure of open meetings, its yearly cycle, and its combination of deliberation and representation—are by now well known. In this article, however, we critically reflect on its global travel and argue for more careful consideration of some of its less well-known features, namely the coupling of the budgeting meetings with the exercise of power.

This paper investigates whether the use of participatory budgeting in Brazilian municipalities during 1990–2004 affected the pattern of municipal expenditures and had any impact on living conditions. It shows that municipalities using participatory budgeting favored an allocation of public expenditures that closely matched popular preferences and channeled a larger fraction of their budgets to investments in sanitation and health services.

This essay is a reflection piece. I identify key principles at the core of how PB functions and to discuss the scope of change we might expect to see generated by these institutions. I move beyond the idea that there is a specific model or set of “best practices” that define PB. Rather, it is most fruitful to conceptualize PB as a set of principles that can generate social change.
