Real Interest Rate (r)
According to economic theory, the real interest rate is the crucial factor influencing spending and saving choices. It is defined as the nominal interest rate adjusted for the expected rate of inflation. This rate reflects the true economic trade-off, representing the quantity of future goods one can obtain by forgoing consumption of goods today.

Assumption of No Inflation in the Intertemporal Choice Model
An individual takes out a one-year loan for $1,000 from a bank that advertises a 7% annual interest rate. At the end of the year, the individual repays the bank $1,070. During that same year, the average price level of goods and services in the economy increased by 3%. Which statement best dissects the components of this financial arrangement?
Identifying the Nominal Interest Rate in a Loan Agreement
Calculating Purchasing Power Change
If you deposit money into a savings account that pays a 2% annual interest rate, and the economy experiences a 3% inflation rate over the same year, your purchasing power will have increased at the end of the year.
When a bank advertises a specific interest rate for a savings account, this publicly stated rate, which does not account for the potential erosion of purchasing power due to a general rise in prices, is referred to as the ______ interest rate.
Match each term to the description that best defines its economic meaning.
Evaluating the Usefulness of the Nominal Interest Rate
A saver is considering depositing $100 into a new savings account. Arrange the following steps in the logical order they would follow to determine the change in their actual purchasing power after one year.
A commercial bank advertises a savings account with a '5% Annual Percentage Rate (APR)'. If a customer deposits $1,000 into this account and there are no other fees or transactions, what does this 5% rate directly determine?

MRT as the Rate of Transforming Future Consumption to Present Consumption
An individual initially chooses to be a saver, meaning they consume less than their income in the present to consume more in the future. If the interest rate increases, what is the definitive effect on their situation, assuming consumption in both periods is a normal good?
Consumption Decision Over Time
Optimal Intertemporal Consumption Choice
Consider an individual who is a borrower, choosing how to allocate consumption between a present period and a future period. If the interest rate they face for borrowing decreases, this individual will unambiguously be made better off.
Arrange the following steps in the correct order to determine an individual's optimal intertemporal consumption choice within the intertemporal choice model.
Match each component of the standard intertemporal choice graph with its correct economic description. The graph's horizontal axis represents 'Consumption Now' and the vertical axis represents 'Consumption Later'.
Analysis of Intertemporal Preferences and Constraints
In a model of choice between consumption now and consumption later, the feasible frontier illustrates all possible combinations of consumption an individual can afford. If the interest rate for borrowing and saving is 8%, the opportunity cost of consuming one additional dollar today is giving up $____ of consumption in the future.
Calculating Maximum Present Consumption
Consider an individual whose income is the same in the present period as it is in the future period. This combination of incomes, where they neither borrow nor lend, is their 'endowment point'. The market allows them to borrow or save at a given interest rate, which defines their feasible consumption possibilities. If this individual's optimal choice involves consuming more in the present than their current income, what must be true about their preferences when evaluated at their endowment point?

Interest Rate as the Opportunity Cost of Present Consumption
An individual takes out a one-year loan where they must pay back 5% more money than they borrowed. During that same year, the general level of prices for all goods and services is expected to increase by 3%. What is the true cost of this loan, measured in terms of the percentage of additional goods and services that must be given up next year to repay the loan?

Evaluating the True Cost of a Loan
An individual borrows $1,000 for one year at an interest rate of 4%. Over the course of that year, the average price of all goods and services in the economy increases by 6%. Based on this information, the borrower effectively gains purchasing power by the end of the year.
Investment Decision and Purchasing Power
A financial analyst is evaluating the outcomes of several one-year loans from the lender's perspective. Match each economic scenario with the correct consequence for the lender's real purchasing power at the end of the loan term.
If a savings account offers a 4% annual interest rate and the expected rate of inflation for the same year is 2.5%, the real rate of return on the savings, representing the actual increase in purchasing power, is ____%.
A person lends money for one year. To determine the actual change in their ability to purchase goods and services at the end of the year, they must perform a series of considerations. Arrange the following steps in the logical order required to calculate the real return on the loan.
