Final answer:
To find the money supply using the money multiplier formula, we can plug in the given values for r, c, and e. The money supply is initially $3.17 billion. If the monetary base is increased by $200 billion, the new money supply is $10,144 billion.
Step-by-step explanation:
To find the value for M, the money supply, we can use the money multiplier formula: (1 + c) / (r + e + c). Plugging in the given values: r = 0.10, c = 0.30, and e = 0.01:
M = (1 + 0.30) / (0.10 + 0.01 + 0.30) = 1.30 / 0.41 = 3.17
Therefore, the money supply is $3.17 billion (rounded to the nearest whole number).
If open market operations increase the monetary base by $200 billion, we need to calculate the new value for the money supply. We can use the same money multiplier formula, but with the new monetary base:
M' = [(1 + 0.30) / (0.10 + 0.01 + 0.30)] * [3000 + 200] = 1.30 / 0.41 * 3200 = 3.17 * 3200 = 10,144
Therefore, the new money supply is $10,144 billion (rounded to the nearest whole number).
