The correct answer to this open question is the following.
Here, we are talking about two terms that were used to identify exchange systems in some regions years ago.
Parma and Paincho are traditional systems of co-operation in that both served as exchange activities. Something like to share and to borrow.
Paincho was used to refer the sharing goods or food to other people when they needed it.
Parma, on the other hand, is the cooperation system that offers help when another person needs it. For instance, people helped a neighbor with some chores, when assistance was required to do something.
So these two systems of cooperation complemented each other.
