In guiding the examination of economists, it often involves the investigation of calculation questions, and some important formulas are often used in calculation questions, so candidates need to remember and learn to use some commonly used formulas in the examination to answer calculation questions. Of course, there are many formulas commonly used by intermediate economists. Chapter 8: Money supply and demand and its balance, involving 10 formulas. For these formulas, we need to master them comprehensively. What I bring to you today is the regular examination for intermediate economists in 2020.

1. transaction equation: MV=PT

Quantity of money in circulation × speed of money circulation = price × total transaction volume of goods and services.

2. Base currency B=C+R= cash in circulation+reserve (current deposit reserve+fixed deposit reserve+excess reserve).

3. Monetary system of the International Monetary Fund

M0= cash in circulation

M 1=M0+ Transferable local currency deposits and foreign currency deposits that can be paid directly in China.

M2=M 1+ corporate time deposits and savings deposits+foreign exchange deposits+large transferable time deposits.

M3=M2+ foreign exchange time deposit+commercial paper+mutual fund deposit+traveler's check.

5. China's monetary system.

M0= cash in circulation

M 1=M0+ company demand deposit

M2=M 1+ savings deposit+company time deposit+other company deposits.

M3=M2+ financial bonds+commercial paper+large negotiable certificates of deposit, etc.

The above formula is commonly used by middle-level economists in 2020: money supply and demand and its balance. I hope I can help you. Of course, candidates preparing for intermediate economists are different from those preparing for intermediate economists full-time. Office workers need to spend more time and make a more comprehensive summary. At this stage, everyone should prepare for the exam carefully. I wish you success in your exam!
