As a democratic innovation involving deliberation and decision making, participatory budgeting (PB) often catalyzes powerful changes among individual participants and within their respective communities. Certain models of PB designate autonomous spaces for young people to determine how to spend a portion of a particular budget, typically that of a municipality or school. These processes of youth PB may address recent trends in the underrepresentation of youth in civic spaces. Following the initial launch of youth participatory budgeting (youth PB) in Cluj (Romania), I spent three weeks in Cluj conducting 45 semi-structured interviews with youth PB participants and one focus group with youth PB facilitators. This thesis explores two areas: (a) the main dynamics of the online Cluj youth PB process (team development and organization, themes of projects proposed and their intended impacts, and inclusion throughout the process) and (b) impact of youth PB on participants (participant learning, change, and empowerment). Main findings suggest that organized groups with ongoing projects dominated the youth PB process and that a majority of projects aspired to impact either all residents of Cluj or a specific youth group (e.g. young artists, young engineers), while very few projects intended to impact young people in Cluj broadly. More than 85% of participants reported feeling empowered by involvement in youth PB. Some differences in learning and change were found by gender, ethnicity, and age. Key recommendations for future iterations of this process include establishing deliberation between teams, encouraging informal group development, restructuring the voting process, and enhancing inclusion of ethnic minorities and migrants.
