Who are the macroeconomic decision makers?

Macroeconomics basically deals with the economics of a nation as a whole! An economy works through its appointed government. The ruling government has economists and strategists on the board who handle the macroeconomics decisions. They can be called decision makers but there are a lot of people working for it. For instance, RBI governor takes major and crucial decision about monetary policy of a country .Finance minister, on the other hand, frames fiscal policy!
