What is international macroeconomics?

International macroeconomics refers to exchanges in between entire nations, typically including concepts like trade deals, tariffs, borrowing, and regulation. Organizations like the International Monetary Fund (IMF) or the World Bank are some of the most important influencers of international macroeconomics, able to drastically change a nation's economic goals or output. International macroeconomics is difficult, if not impossible, to disentangle from political relations between countries, since some countries make for favorable trade partners while some countries do not.
