The following information is available to you: travelers' checks = $1 million; coin and paper currency = $30 million; repurchase agreements and Eurodollars = $15 million; demand deposits = $25 million; retail money market mutual funds = $60 million; savings accounts at depository institutions = $40 million; checkable deposits at depository institutions = $35 million; large-denomination time deposits = $50 million; institutional money market mutual funds = $65 million; and small-denomination time deposits = $45 million. Using Fed definitions, determine the dollar sizes of the following:

a. Ml money supply
b. M2 money supply
c. M3 money supply

To determine the dollar sizes of the different money supplies using the definitions provided by the Fed, we need to categorize the given information accordingly.

a. M1 money supply includes the most liquid forms of money. It consists of:

- Demand deposits: $25 million
- Checkable deposits at depository institutions: $35 million
- Travelers' checks: $1 million

M1 money supply = $25 million + $35 million + $1 million = $61 million

b. M2 money supply includes M1 money supply plus certain other less liquid forms of money. It consists of:

- M1 money supply: $61 million
- Savings accounts at depository institutions: $40 million
- Small-denomination time deposits: $45 million
- Retail money market mutual funds: $60 million

M2 money supply = $61 million + $40 million + $45 million + $60 million = $206 million

c. M3 money supply includes M2 money supply plus other even less liquid forms of money. It consists of:

- M2 money supply: $206 million
- Large-denomination time deposits: $50 million
- Institutional money market mutual funds: $65 million
- Repurchase agreements and Eurodollars: $15 million

M3 money supply = $206 million + $50 million + $65 million + $15 million = $336 million

So, the dollar sizes of the money supplies are as follows:

a. M1 money supply = $61 million
b. M2 money supply = $206 million
c. M3 money supply = $336 million

To determine the dollar sizes of the M1, M2, and M3 money supply using the given information, we need to understand the components of each money supply measure.

1. M1 money supply includes the most liquid forms of money, which are readily available for transactions. It consists of the following components:
- Demand deposits: $25 million
- Travelers' checks: $1 million
- Other checkable deposits: Checkable deposits at depository institutions: $35 million

To calculate M1 money supply:
M1 = Demand deposits + Travelers' checks + Other checkable deposits
M1 = $25 million + $1 million + $35 million
M1 = $61 million

Therefore, the dollar size of M1 money supply is $61 million.

2. M2 money supply includes all components of M1 and adds some less liquid forms of money, such as savings accounts and retail money market mutual funds. It consists of the following components that are not included in M1:
- Savings accounts at depository institutions: $40 million
- Small-denomination time deposits: $45 million
- Retail money market mutual funds: $60 million

To calculate M2 money supply:
M2 = M1 + Savings accounts + Small-denomination time deposits + Retail money market mutual funds
M2 = $61 million + $40 million + $45 million + $60 million
M2 = $206 million

Therefore, the dollar size of M2 money supply is $206 million.

3. M3 money supply includes all components of M2 and adds some even less liquid and broader forms of money, such as large-denomination time deposits and institutional money market mutual funds. It consists of the following components that are not included in M2:
- Large-denomination time deposits: $50 million
- Institutional money market mutual funds: $65 million

To calculate M3 money supply:
M3 = M2 + Large-denomination time deposits + Institutional money market mutual funds
M3 = $206 million + $50 million + $65 million
M3 = $321 million

Therefore, the dollar size of M3 money supply is $321 million.

Summary:
a. M1 money supply = $61 million
b. M2 money supply = $206 million
c. M3 money supply = $321 million
