TPP tells us about Production PossibilitiesTPP tells us about Production Possibilities And MPP tells us the effect of hiring more workersAnd MPP tells us the effect of hiring more workers But need to translate production information into costs per unit of production.But need to translate production information into costs per unit of production. That way can compare cost of producing with revenue (price) from selling.That way can compare cost of producing with revenue (price) from selling.
