Marco's Optimal Choice When Lending: Point D (60, 48)
Point D, at coordinates (60, 48), represents Marco's optimal choice when he has the option to lend at a 20% interest rate. This point is located on the lending feasible frontier where it is tangent to his highest attainable indifference curve, labeled 'Marco’s IC (medium utility)'. This tangency indicates the consumption bundle that maximizes his utility given the opportunity to lend.

Effect of an Interest Rate Increase on Julia's and Marco's Feasible Frontiers (Figure 9.14)
An individual is a net lender, meaning they consistently save some of their current income to consume more in the future. If the interest rate they earn on their savings increases, how would this change influence their decision about how much to consume now?

Explaining a Saver's Response to an Interest Rate Change
True or False: Following a significant increase in the interest rate, an individual who lends money will always choose to lend more because the reward for postponing consumption has increased.
For an individual who lends a portion of their income, an increase in the interest rate creates two distinct effects on their decision to consume now versus save for the future. Match each effect with its correct description.

Suppose an individual who regularly lends a portion of their income sees a significant increase in the interest rate they receive. Following this change, you observe that they choose to increase their current consumption. What can be definitively concluded about the economic effects influencing their decision?

An individual has $200 available today. They can consume it now or lend any portion of it at an interest rate of 10% to be repaid in the future. Which of the following combinations of 'consumption now' and 'consumption later' is not in their feasible set?
Financial Planning with Interest
Impact of Interest Rate Changes on Consumption Possibilities
An individual's 'feasible frontier' shows all possible combinations of consumption today and consumption in the future, given an initial amount of money and an opportunity to lend. Match each financial scenario below with the correct maximum possible amount of consumption in the future (assuming all initial money is lent).
An individual has an initial amount of money and can either consume it today or store it for future consumption. They are then offered a new option: they can lend any portion of the money at a positive interest rate. True or False: This new lending opportunity reduces the total set of possible consumption combinations available to the individual.
Comparing Financial Strategies
An individual has an initial endowment of $500 to be consumed either today or in the future. They have the opportunity to lend any portion of this money at an interest rate of 15%. If this individual chooses to consume $200 today, the maximum amount they can have for consumption in the future is $____.
Comparing Investment Opportunities
An individual has an initial endowment of money to be consumed either today or in one year. They also have the opportunity to lend any portion of it at a fixed interest rate. Arrange the following steps in the correct logical order to construct the 'feasible frontier' that represents all possible combinations of consumption today and consumption in one year.

An individual is deciding how to allocate their consumption between today and one year from now. At their current consumption plan, their personal willingness to trade future consumption for present consumption is 1.15 (meaning they are willing to give up $1.15 of future consumption for $1.00 of present consumption). The market interest rate allows them to trade $1.00 of present consumption for $1.08 of future consumption. To improve their overall well-being (utility), what action should this individual take?
Analyzing an Intertemporal Consumption Decision
An individual makes choices about consumption in the present versus consumption in the future. Match each key concept related to this decision-making process with its correct description.
Analyzing a Suboptimal Intertemporal Consumption Choice
Consider an individual deciding how to allocate consumption between the present and the future. If this person's subjective willingness to trade one unit of future consumption for one unit of present consumption is lower than the trade-off offered by the market interest rate, they have achieved their most preferred (optimal) balance of consumption over time.
Evaluating a Government Savings Policy
For an individual to achieve their optimal consumption plan over time, their subjective discount rate—the measure of their personal preference for present consumption over future consumption—must be equal to the market ________.
Arrange the following steps in the logical order that describes the process of finding an individual's optimal plan for consumption over two time periods (present and future).
Evaluating an Intertemporal Consumption Plan
An individual is allocating their income between consumption now and consumption one year from now. At their current consumption level, they are personally willing to give up $1.05 of future consumption to gain $1.00 of present consumption. The annual market interest rate is 7%. Which statement correctly analyzes this individual's situation?

Given that the Gini coefficient for market income in the Netherlands in 2020 was 0.40 and the Gini coefficient for disposable income was 0.31, it can be concluded that government redistributive policies during that year led to an increase in income inequality.
An individual has an endowment of $100 for current consumption and $0 for future consumption. They can lend any portion of their current endowment at a 20% interest rate. They choose a consumption plan of $60 now and $48 later. Which statement provides the most accurate economic analysis of this choice?
Analyzing Non-Optimal Consumption Choices
Analysis of an Intertemporal Consumption Choice
An individual has an endowment of $100 for current consumption and $0 for future consumption. They can lend at a 20% interest rate and choose an optimal consumption plan of $60 now and $48 later. Match each economic concept to its correct value or description in this scenario.
An individual has an endowment of $100 for current consumption and $0 for future consumption. They can lend at a 20% interest rate. If this individual's preferences lead them to an optimal choice of consuming $60 now and $48 later, then a different consumption plan of $70 now and $36 later would place them on a lower indifference curve.
An individual has an endowment of $100 for current consumption and $0 for future consumption. They can lend at a 20% interest rate. Their optimal choice is to consume $60 now and $48 later. At this optimal point, the individual's subjective trade-off rate between future and current consumption (their Marginal Rate of Substitution) must be equal to ____.
Evaluating Financial Advice on Intertemporal Choice
An individual starts with an endowment of $100 for today and nothing for the future. They discover they can lend money at a 20% interest rate. Arrange the following steps in the logical order they would follow to determine their optimal consumption plan for today and the future.
An individual has an endowment of $100 for current consumption and $0 for future consumption. They can lend at a 20% interest rate. Their optimal consumption plan is to consume $60 now and $48 later.
