The arrangement described, where Kayla and the other parents take turns providing transportation for their children, is an example of a barter system. In a barter system, goods or services are exchanged directly between individuals without the use of money. In this case, the parents are trading the service of transporting children, eliminating the need for each parent to individually hire a transportation service or pay for separate forms of transportation. This arrangement demonstrates a cooperative effort within a community, with each parent providing a service in exchange for the same service being provided to them at a later time. It is an element of a traditional economy because it relies on mutual trust and interpersonal relationships rather than monetary transactions to meet the needs of the group.
