1)What is the best way for a layman to better understand macroeconomics?

2)Is it a good idea to leave a major macroeconomic decision like Brexit in the hands of common man?

3)Is economic policy in fostering the economy considered as part of the government's macroeconomic policy?

1)The word macro in the term macroeconomics means large. Macroeconomics is a branch of economics which takes into consideration the large segments of the economy. It focuses on problems such as unemployment, inflation, nation total output which are studied in the context of the whole economy.

For example when the savings of an individual is considered, it becomes a small concept. But when the savings of the economy as a whole is studied, it is a macroeconomic concept.

2)It would not be a good idea to leave the important macroeconomic decisions in the hands of the common man. As every individual will see the macroeconomic situation differently and decisions taken by them will be according to individual welfare and for the whole county. Leaving major economic decisions in the hands of the common man will bring various macroeconomic problems. It will also lead to conflicts in the country. It can also turn the economy of the country downwards.

3)Yes, any economic policy which fosters the economy is considered as a part of the government's macro-economic policy. It is because any policy undertaken by the government affects all section of the society and thus the economy as a whole. For example, if the government imposes or reduces taxes, then this increase or decrease in taxes will affect a large part of the population. With the increase or decrease in taxes, the consumption will get affected, and thus the overall economy will get affected.

Therefore, one can conclude that any step taken by the government to foster the economy (example- increasing government expenditure) will affect the overall economy and will be considered as a part of the macro-economic policy.
