Answer:
A. increase the money supply and encourage economic growth.
Step-by-step explanation:
The Federal Reserve may buy government securities in open market operations in order to increase the money supply and encourage economic growth.
An increase in the supply of money works both through
1. Lowering interest rates, which spurs investment, and
2. Through putting more money in the hands of consumers, making them feel wealthier, and thus stimulating spending.
3. It also increases wage rate and reduces unemployment (because the increased investment will need more workers for increased production) as unemployment increases as inflation (more money in the economy) increases.
Opposite effects occur when the supply of money falls or when its rate of growth declines.
