The advantage of such a policy is that it encourages manufacturers to distribute the medicines in question in the target countries at the lowest possible ("tiered") price, while at the same time recouping their research and development expenditure with the higher prices charged in developed countries.
Prednost takve politike poticanje je proizvođača da distribuiraju predmetne lijekove u ciljanim zemljama po najnižoj mogućoj („diferenciranoj") cijeni, a izdatke za istraživanje i razvoj nadoknađuju višim cijenama u razvijenim zemljama.
