Exchange and transaction management according to the Edgeworth box

For organism A the lineage is OA and for someone B OB. In the derivation OA the initial capital is that soul A owes aught whereas soul B owes the total free assets of artefact X and Y. In source OB individual A owes everything and individual B aught. From OA the passivity curves UAI,UAII and UAIII present which combinations of X and Y relent the corresponding turn of service (goodness) for A. The far the passiveness curves are set from the lineage, the higher the secondary (welfare) for A. For being B the mirror simulacrum holds legitimate from extraction OB with indifference curves UBI, UBII and UBIII.. The more UB is gone from the source OB, the higher is the inferior and eudaemonia for individual B.
