This case study features the ten 2007/2008 Citizen Conferences, each consisting of 8 to 10 New Mexican Adult Citizens and lasting 9 hours. This series of deliberative events was convened by the New Mexico Department of Transportation (NMDOT) and the University of New Mexico's Institute for Public Policy (IPP) to gather public feedback, so that the State could best meet the transportation needs of its citizens.
Participatory decentralization is the process of handing out legitimate political authority to the citizens. It contributes to democratization by bringing the government ‘closer to the people’, imparting the citizens with political knowledge through their participation in local management, and making the government more accountable. 
This case is a randomized field experiment, which examines the differences in decision-making and legitimacy in town meeting versus plebiscitary (direct voting) methods of decision. The experimenter - Benjamin Olken - examined this question in the context of decisions about infrastructure investments in Indonesian villages.
