I believe the answer is: The effects of a tax increase on the gross domestic product
The influence of economic challenges, such as inflation and stagflation
The result of a major government soending program on the national unemployment rate
Macro economics study how the performance, structure, behavior, and decision-making that made by both private and government sector affect the economy as a whole.
Because of this, macro economics students would focus their attention on things such as national inflation, national employment rate, Total GDP in a year, the amount of international balance, National Economic growth , etc.
