The document provides instructions for a decision exercise where participants can earn money by making investment decisions. Participants will be randomly assigned to a group of 5 and must complete the 30-40 minute exercise without interruptions. They can earn $1 for viewing instructions, $1.5 for completing it, and up to $8 more based on decision outcomes. The exercise involves allocating tokens between private economic activities near or far from a river, and public infrastructure to control flooding from the river. Participants' earnings will depend on their group's collective decisions.
