In macroeconomics, if a credit card account is the overdraft limit of a credit card, it is nothing but a credit limit.

When you overdraft for consumption, it is equivalent to the bank paying the money for you first, and you owe the bank the money, and if it is a normal savings in a credit card, it belongs to M2.

M2 = M1 + personal savings deposits + corporate time deposits + self-raised capital construction deposits + securities reserve deposits + other deposits.

What is macroeconomics:

The higher the degree of liquidity , the stronger the purchasing power, the lower the degree of liquidity and the weaker the purchasing power.

In Western economics, the study of a country's economic aggregate, aggregate demand and aggregate supply, total national income and composition, currency and finance, population and employment, factors and endowments, business cycle and economic growth, economy Expectations and economic policy, international trade.

A discipline related to macroeconomic phenomena such as international economics. Macroeconomics is a branch of economics that has developed rapidly since the publication of John Maynard Keynes's "The General Theory of Employment, Interest and Money."

It is classified as macroeconomics and belongs to the Western economics paradigm. Since the macroeconomic field and the microeconomic field are separated for research, the relationship with scientific general economics is neither the relationship between the whole and the part, nor the relationship between the whole and the part. It is not a general and special relationship.

Therefore, it is impossible to study the general laws of economic development and the special laws of the macroeconomic field. We can only describe the economic phenomena at the macro level in a phenomenological sense.

From a scientific perspective, macroeconomics cannot become a discipline in the true sense because it cannot study general economic laws and special economic laws in the field of macroeconomics.

The research direction is in macroeconomics, which takes the activities of the general process of the national economy as the research object, and mainly examines the overall level of employment, total national income and other economic aggregates.

Therefore, macroeconomics is also called employment theory or income theory. Macroeconomics studies the utilization of economic resources.

Including national income determination theory, employment theory, inflation theory, business cycle theory, economic growth theory, fiscal and monetary policy.
