negative currencies



each slip of paper represents an item of negative value


	clean the house (an obligation to do that)

	a debt

	other debt item




work process


	positive currency



		party 1 does some work

		party 2 gives some positive currency to party 1



	negative currency


		party 1 does some work

		party 1 gives a negative currency slip to party 2





could be effective in preventing the accumulation of large debts

should be physically very different from positive currency, e.g. different color

has the advantage the once work has been requested, the slips can be delivered, 

	there is no need to obtain the payment from the other party

could create negative effects
