As the first ward-based participatory budgeting experiment in the United States, the Participatory Budgeting Initiative in Chicago's 49th Ward began in November of 2009 with the goal of directly allocating a portion of the Alderman’s capital budget for the 49th Ward by residents. Citizens gathered to discuss, deliberate, and vote into implementation projects totaling $1.3 million dollars.

In January 2008, the Municipality of Livorno decided to experiment an innovative type of decision making process concerning the renewal and the future use of the 'Cisternino', an ancient building historically used for water supply.
