This, basically, is the logic of Keynesian economics, which says that governments have a role to play in macro-economic management through policy tools: monetary exchange rate and budget policy.
To je, u biti, logika Kejnzijanske ekonomije, po kojoj vlade moraju da igraju ulogu u makroekonomskoj politici pomoću instrumenata kao što su monetarni kurs i budžetska politika.
