Final answer:
If nominal GDP is 1400 and the money supply is 350, the velocity is 4, as it is calculated by dividing the nominal GDP by the money supply.
Step-by-step explanation:
If nominal GDP is 1400 and the money supply is 350, to calculate velocity, you use the equation Velocity = Nominal GDP / Money Supply. Therefore, Velocity = 1400 / 350, which equals 4. This means that every dollar of the money supply circulates 4 times within the economy to achieve the nominal GDP of 1400.
Answering the supplementary questions provided:
- With an expected increase in the velocity of money by 50%, the nominal GDP would increase correspondingly, because an increased velocity implies each dollar is used more often in transactions.
- With a GDP of 1,500 and a money supply of 400, the velocity is 3.75 (1,500 / 400).
- If the GDP rises to 1,600 and the money supply remains unchanged, the velocity has increased, indicating that the average dollar is circulating more frequently.
- If the GDP falls back to 1,500 and the money supply falls to 350, the velocity is again 4.29 (1,500 / 350), indicating that the average dollar circulates more times in the economy after the fall in money supply.
