Question 1

1. The municipal bonds
2. The savings account balance
3. The checking account balance (correct answer)
4. The household's credit card available limit
5. The household's stock mutual fund shares

Explanation: Money is any widely accepted asset for exchange, valuation, and value storage, with M1 including currency and checking accounts for their liquidity, and M2 adding savings and similar near-money. In the household's holdings, the checking account balance is included in M1 as it allows direct payments via checks or transfers. This inclusion applies due to its high liquidity and use in everyday transactions, distinguishing it from less liquid assets like savings (M2) or bonds (excluded). A common misconception is that a household's credit card available limit is money, but credit is not; it is access to loans, not a monetary asset. To assess inclusion, evaluate liquidity and acceptability—checking excels in both for M1 qualification. This strategy clarifies why stock mutual funds are not in M1 or M2, as they require sale for cash.

Question 2

1. Medium of exchange used to make a payment for goods or services (correct answer)
2. Unit of account used to measure the worker's productivity
3. Store of value used primarily to earn interest like a bond
4. Store of value used primarily to avoid all inflation risk
5. Unit of account used to convert credit limits into spending power

Explanation: Money acts as a medium of exchange to facilitate trades, unit of account for valuation, and store of value over time, with M1 including highly liquid forms like checking deposits used in payments. The worker's paycheck goes into checking, then electronically transfers for rent. This demonstrates money as a medium of exchange, enabling seamless payment without direct barter. It applies because checking deposits allow immediate, accepted transactions, embodying exchange efficiency. Misconception: credit limits don't function as money; they defer costs via borrowing. Tip: assess liquidity (quick access) and acceptability (universal use) to identify functions in scenarios like payments.

Question 3

1. The balance in the worker's checking account (correct answer)
2. The worker's credit card spending limit
3. A 10-year government bond held by the worker
4. The worker's shares in a stock index fund
5. The worker's home equity value

Explanation: M1 represents the most liquid money supply—assets immediately available for transactions. When the worker receives direct deposit into a checking account, that balance becomes part of M1 because it can be instantly accessed via debit card for purchases like groceries. The checking account balance is the only listed item in M1. Credit limits, bonds, stocks, and home equity aren't included in M1 (or M2) because they either represent borrowing capacity or require selling/conversion before use as payment. The key insight: M1 includes only currency in circulation and checkable deposits—money you can spend right now without any conversion.

Question 4

1. Money serving as a store of value
2. Money serving as a unit of account (correct answer)
3. Money serving as a medium of exchange
4. Credit serving as a store of value
5. Bonds serving as a medium of exchange

Explanation: Money's three functions help economies operate efficiently. When the retailer posts prices like "$2.49 per bottle," money is serving as a unit of account—a common measuring stick for value. This allows customers to compare prices across different stores and products using a standardized scale. Without this function, we'd need complex barter ratios (how many shirts equal a bottle?). Money as a unit of account isn't about physical exchange or storage, but about expressing and comparing values. When you see prices quoted in dollars, that's the unit of account function at work.

Question 5

1. Currency and checking deposits (correct answer)
2. Checking deposits and corporate bonds
3. Savings deposits and corporate bonds
4. Currency and the credit card limit
5. Savings deposits and the credit card limit

Explanation: M1 consists of only the most liquid money forms: currency in circulation and checkable (demand) deposits. From the person's assets, only the $150 in currency and $1,200 in checking deposits qualify for M1. Savings accounts ($3,500) are part of M2 but not M1 due to potential withdrawal restrictions. Corporate bonds ($4,000) aren't money—they're securities that must be sold before use as payment. Credit card limits ($2,000) represent borrowing capacity, not actual money assets. The defining characteristic of M1 components: they can be used immediately for transactions without any conversion or delay.

Question 6

1. M1 rises because the credit card purchase creates new money immediately
2. M1 falls because the credit card purchase removes checking deposits from circulation
3. M1 is unchanged because the credit card purchase is financed by borrowing, not money (correct answer)
4. M2 rises because the credit card limit is added to savings deposits
5. M2 falls because the purchase converts savings deposits into a bond

Explanation: Money aggregates define M1 as currency and checkable deposits, M2 as M1 plus savings, excluding credit transactions which are loans, not money creation. The person holds currency, checking, savings, and uses a credit card for a textbook purchase. M1 remains unchanged as the credit card buy is financed by borrowing, not altering money holdings. This holds because credit extends debt, not new money, preserving existing aggregates. Misconception: credit card use doesn't create money; it's temporary borrowing. Strategy: check liquidity and acceptability—borrowing lacks the direct usability of true money.

Question 7

1. A $10 bill used to pay for the coffee
2. A debit card payment drawing from a checking deposit
3. A credit card payment that creates a short‑term loan (correct answer)
4. A check written on a checkable deposit
5. Currency held by the public before the purchase

Explanation: Money functions as a medium of exchange, unit of account, and store of value, with M1 including currency and checkable deposits, and M2 expanding to savings and money market funds, but excluding credit-based instruments. At the café, payments involve currency, debit from checking, and credit card. The credit card payment is not counted in M1 or M2 because it creates a short-term loan rather than using existing money. This classification holds as credit cards facilitate borrowing, not direct money transfer, unlike currency or checking deposits in M1. A frequent misconception is viewing credit as money, but it merely defers payment without being a liquid asset. For similar analyses, evaluate liquidity—how easily convertible without loss—and acceptability, noting that credit lacks inherent value as money.

Question 8

1. The $150 in currency held in a wallet
2. The $1,200 in a checking account balance
3. The $4,000 in a savings account balance (correct answer)
4. The $2,000 in corporate bonds held in a brokerage
5. The $3,000 credit card available limit

Explanation: Money is anything accepted for payments with key functions, aggregated in M1 (currency, checkable deposits) for high liquidity, and M2 (including M1 plus savings and small time deposits like CDs), excluding bonds and credit limits. The household holds currency, checking balance, savings balance, and a CD. The $4,000 savings account is in M2 but not M1, as savings are less liquid than checking deposits but still near-money. This applies because savings can be quickly accessed but often lack check-writing features, fitting M2's broader scope. Misconception: credit limits are not money, as they represent potential debt, not actual holdings. Strategy: check liquidity and acceptability—savings score high on both but not as immediately as M1 components.

Question 9

1. Money serving as a medium of exchange
2. Money serving as a unit of account
3. Money serving as a store of value (correct answer)
4. Credit serving as a store of value
5. Bonds serving as a medium of exchange

Explanation: Money's store of value function means it preserves purchasing power over time. When the family keeps $2,000 in savings for emergencies, they're using money to store value—maintaining wealth in a form that can be accessed when needed. Unlike the medium of exchange function (active spending) or unit of account (price measurement), store of value is about holding money for future use. While savings accounts aren't as liquid as cash, they reliably maintain value better than perishable goods. This function explains why people hold money balances rather than immediately spending everything. The key: if money is being saved for later use, it's functioning as a store of value.

Question 10

1. The currency held by the household
2. The checking account balance
3. The savings account balance (correct answer)
4. The unused credit line on a credit card
5. The corporate bond held by the household

Explanation: Money aggregates are classified by liquidity levels. M1 contains the most liquid assets: currency and checkable deposits. M2 includes everything in M1 plus less liquid but still accessible assets like savings accounts, money market accounts, and small CDs. From the household's assets, currency ($600) and checking ($1,400) are in M1. The savings account ($8,000), money market account ($2,000), and 6-month CD ($5,000) are in M2 but not M1. Corporate bonds aren't included in either aggregate as they lack immediate liquidity. To identify M2-only assets, check if they're readily accessible but require some conversion to spend.

Question 11

1. The currency held by the person
2. The checking account balance
3. The U.S. Treasury bonds
4. The savings account balance (correct answer)
5. The credit card limit available

Explanation: Money aggregates are organized by liquidity levels, with M2 encompassing all of M1 plus additional near-money assets. M1 includes currency ($300) and checking deposits ($700)—the most liquid forms. M2 adds savings accounts ($5,000) and money market mutual funds ($1,500), which are slightly less liquid but still readily convertible to cash. U.S. Treasury bonds ($2,000), while safe government securities, aren't included in either aggregate because they must be sold in markets before use as payment. Credit card limits are borrowing capacity, not money. To identify M2-exclusive assets, look for accounts that are accessible but may have withdrawal restrictions.

Question 12

1. The savings account balance
2. The checking account balance
3. The U.S. Treasury bonds (correct answer)
4. The currency in the cash register
5. The firm's credit card account

Explanation: Money is anything widely accepted for payments, valuing goods, and holding purchasing power, with M1 aggregating currency and checkable deposits, and M2 including M1 plus savings, small time deposits, and money market accounts. In the firm's assets, the U.S. Treasury bonds are excluded from both M1 and M2 because they are investment securities that must be sold to convert to money, lacking the liquidity of true monetary assets. This exclusion applies as bonds do not function directly as a medium of exchange or near-money, unlike the currency in the cash register (M1) or savings account (M2). A common misconception is that the firm's credit card account counts as money, but credit is not money; it facilitates borrowing but is not an accepted asset in money supply measures. Always verify an asset's classification by assessing its liquidity and acceptability for immediate transactions—bonds fail this test, requiring market sale. This strategy helps differentiate monetary assets from other financial holdings like securities.

Question 13

1. The currency held by the student
2. The checking account balance
3. The savings account balance
4. The credit card balance owed (correct answer)
5. The student's demand deposit

Explanation: Money encompasses assets functioning as medium of exchange, unit of account, and store of value, measured by M1 (currency, demand deposits) and M2 (M1 plus savings, small CDs). Among the student's items, the credit card balance owed is not money and is excluded from both M1 and M2, as it represents debt rather than a liquid asset for transactions. This exclusion applies because credit balances are liabilities, not acceptable payment forms like currency or deposits. A common misconception is equating credit with money, but credit is not money; it defers payment without adding to the money supply. Use the strategy of checking liquidity and acceptability to verify—credit lacks inherent liquidity as it's borrowing, not holdings. This approach highlights why demand deposits (like checking) are in M1, while credit is entirely outside aggregates.

Question 14

1. The savings account balance (correct answer)
2. The mutual fund shares
3. The checking account balance
4. The currency held by the student
5. The student's credit card balance

Explanation: Money functions as a medium of exchange, unit of account, and store of value, with M1 measuring the most liquid forms like currency and checking deposits, and M2 adding less liquid items such as savings accounts and mutual fund shares if they are money market types. Referring to the student's assets, the savings account balance is included in M2 but not in M1 because it provides liquidity but typically requires transfer to a checking account for direct use in transactions. This classification applies as savings accounts are near-money, offering interest and easy access but not the immediate transactability of M1 components. A common misconception is that a student's credit card balance is money, but credit is not money; it is a liability representing deferred payment rather than an asset in the money supply. To determine inclusion in money aggregates, check an asset's liquidity and general acceptability as payment—savings score high on liquidity but lower on direct acceptability compared to checking. This transferable strategy aids in understanding why mutual funds, unless specified as money market, are often excluded from M2.

Question 15

1. The checking account balance
2. The savings account balance
3. The currency held by the person
4. The stock mutual fund shares (correct answer)
5. A small time deposit at a bank

Explanation: Money aggregates M1 and M2 include only highly liquid assets that can function as money. M1 contains currency and checking deposits; M2 adds savings accounts, money market funds, and small time deposits. Stock mutual fund shares ($2,000) are excluded from both aggregates because they're financial investments that must be sold before being used as payment, with values that fluctuate. The person's currency ($80), checking ($500), and savings ($4,000) are all included in money measures. Credit limits aren't money—they represent borrowing capacity, not existing assets. To determine inclusion, ask: "Can this be quickly used for payment without selling it first?"

Question 16

1. Money as a medium of exchange used to complete transactions
2. Money as a unit of account used to quote and compare prices (correct answer)
3. Money as a store of value used to preserve purchasing power over time
4. Money as a form of credit used to postpone payment
5. Money as a bond substitute used to earn interest

Explanation: Money performs three main functions: medium of exchange for transactions, unit of account for pricing, and store of value for preserving wealth, with aggregates like M1 (currency, checking) and M2 (plus savings) measuring supply. In the grocery store, eggs and milk prices are listed in dollars, allowing comparison across brands. This illustrates money as a unit of account, providing a common measure for value assessment. The function applies as consistent pricing enables efficient economic decisions without barter complexities. Misconception: credit cards aren't money; they extend loans, not serve as a pricing unit. Strategy: examine liquidity and acceptability—prices in money units must be stable and widely recognized for comparisons.

Question 17

1. The currency held by the individual
2. The checking account balance
3. The certificate of deposit (CD) (correct answer)
4. The individual's credit card limit
5. The individual's corporate stock shares

Explanation: Money is defined by its roles as medium of exchange, unit of account, and store of value, with M1 capturing currency and checking for high liquidity, and M2 adding items like savings and certificates of deposit (CDs) that are less immediately usable. Based on the individual's assets, the certificate of deposit is in M2 but not M1, as it is a time deposit offering interest but penalizing early withdrawal, reducing its transactability. This classification fits because CDs are near-money, convertible to cash but not directly spendable like checking accounts. A common misconception is that an individual's credit card limit is money, but credit is not; it is potential debt, not an asset in money aggregates. To classify correctly, check liquidity and acceptability—CDs are liquid upon maturity but not as acceptable for instant payments. This method also explains why stock shares are excluded from both M1 and M2.

Question 18

1. Money serving as a store of value
2. Money serving as a medium of exchange (correct answer)
3. Money serving as a unit of account
4. Credit serving as a medium of exchange
5. Money serving as the primary definition of wealth

Explanation: Money serves three key functions: as a medium of exchange for transactions, a unit of account for pricing, and a store of value for saving, with aggregates like M1 (currency, checking) and M2 (M1 plus savings, etc.) measuring its availability. In the described transaction, using a debit card linked to a checking account to buy groceries illustrates money as a medium of exchange, as the funds are immediately transferred from the account to the store. This function applies because the debit facilitates direct, accepted payment without barter or delay, drawing from M1 components. A common misconception is that credit serves as a medium of exchange, but credit cards defer payment and represent borrowing, not actual money from deposits. To identify money's role or classification, check liquidity and acceptability—debit transactions rely on highly liquid, acceptable checking funds. This approach also clarifies why options like money as a store of value are less directly illustrated here, as the focus is on exchange.

Question 19

1. Money serving as a medium of exchange
2. Money serving as a unit of account (correct answer)
3. Money serving as a store of value
4. Bonds serving as a unit of account
5. Credit cards serving as money

Explanation: Money's functions include acting as a medium of exchange, unit of account, and store of value, supported by aggregates such as M1 for liquid transaction money and M2 for broader savings-like assets. The restaurant's use of dollar prices for menu items directly illustrates money as a unit of account, enabling customers to compare and value options consistently. This function applies because prices in a common unit simplify economic decisions, avoiding the complexity of relative valuations in barter systems. A common misconception is that credit cards serve as money, but they are not; they provide borrowing access, not a standard measure or store of value like actual currency or deposits. When evaluating assets or functions, assess liquidity and acceptability—dollar prices are acceptable everywhere for accounting purposes. This strategy helps distinguish unit of account from medium of exchange, as seen in bonds not serving as pricing units.

Question 20

1. The corporate stock shares
2. The savings account balance (correct answer)
3. The person's credit card line of credit
4. The corporate bond holdings
5. The store gift card balance

Explanation: Money serves as medium of exchange, unit of account, and store of value, aggregated in M1 for transaction-ready items like currency and checking, and M2 for broader inclusions like savings accounts. From the person's assets, the savings account balance is included in M2 as it offers liquidity and interest but is not directly transactable like M1 components. This applies because savings are near-money, easily convertible but added beyond M1's narrow scope. A common misconception is that a person's credit card line of credit is money, but credit is not; it represents borrowing potential, not actual money supply. Classify by checking liquidity and acceptability—savings are highly liquid but less acceptable for direct payments than checking. This transferable method explains exclusions like corporate stocks or bonds from M2, as they are investments, not money.
