Q. Who will participate and how decision will be made are issues concerned with Public Choice.

Whether participants are guided by social concerns or they harbour their private interests as well and what implications of different behaviours are. Whether participants are citizens or their elected representatives and how they were elected, or they are part of selected personnel of bureaucracy. Whether it's voting by secret ballot for election of representatives or a committee is meeting using no-dissent rule or a board is meeting where chair finally rules.
