Which best describes why a government’s actions are important within macroeconomics?

Because the government can use a policy to influence the economy.

A policy issued by corporation only affect the one that doing business with them. But a policy which issued by the government , will affect ALL economic Activity in the country as a whole, since all people have to obey its regulation. That's why government's actions are very important within macroeconomics
