Marco's Optimal Lending Choice at Point D
To determine the amount he will lend, Marco identifies the optimal point on his feasible frontier that allows him to reach his highest possible indifference curve. This optimal choice, represented as point D in the figure, occurs at the point of tangency between the feasible frontier and an indifference curve. At this point, his Marginal Rate of Substitution (MRS) between present and future consumption is equal to the Marginal Rate of Transformation (MRT), which reflects the market cost of transferring consumption from the present to the future.

Marco's Optimal Lending Choice at Point D
An individual has an endowment of $200 for consumption now and has the opportunity to lend any portion of it at a 10% interest rate to fund consumption in the future. The horizontal axis represents 'consumption now' and the vertical axis represents 'consumption later'. Which of the following combinations of consumption now and consumption later is NOT a point on this individual's feasible frontier?
Interpreting the Feasible Frontier's Slope
Evaluating a Consumption Plan's Feasibility
An individual's consumption possibilities over two periods are represented by a feasible frontier on a graph where the horizontal axis is 'consumption now' and the vertical axis is 'consumption later'. Match each scenario, defined by an initial endowment and a lending interest rate, to the correct description of its feasible frontier.
An individual has an endowment of $100 to be consumed now and can lend any portion of it at a constant 20% interest rate. The feasible frontier representing all possible combinations of 'consumption now' and 'consumption later' is a curve that bows outwards from the origin.
An individual has an initial endowment of $500 for consumption in the present period and can lend any portion of this amount at an interest rate of 15%. If this individual decides to lend their entire endowment, the maximum amount they can have for consumption in the future period is $____.
An individual starts with an endowment of wealth entirely in the present and has the opportunity to lend some or all of it at a fixed interest rate. Arrange the following steps in the correct logical order to determine the feasible frontier for their 'consumption now' versus 'consumption later'.
Impact of Interest Rate Changes on Consumption Possibilities
Evaluating a Financial Advisor's Claim
An individual's feasible set of consumption choices is represented by a straight line on a graph where the horizontal axis is 'consumption now' and the vertical axis is 'consumption later'. This line, which shows all possible combinations if the individual lends some of their initial wealth, passes through two specific points: (Consumption Now = $80, Consumption Later = $22) and (Consumption Now = $50, Consumption Later = $55). Based on this information, what is the interest rate at which this individual can lend?

Learn After
An individual has $100 of consumption available today and can lend money at a 20% interest rate. They are considering a plan where they consume some money today and lend the rest. At their currently considered consumption plan, their personal willingness to trade one dollar of consumption today for dollars of consumption in the future is 1.1. Given that the market allows them to trade one dollar today for $1.20 in the future, which of the following actions would allow the individual to reach a higher level of satisfaction, and why?
Analyzing an Individual's Lending Decision
Condition for Optimal Lending
An individual has found their optimal combination of consumption today and consumption tomorrow by lending some of their initial endowment. At this optimal point, any further lending would place them on a lower indifference curve.
An individual has found their optimal combination of consumption today and consumption tomorrow by lending some of their initial endowment. At this optimal point, any further lending would place them on a lower indifference curve.
An individual is deciding how much of their current income to consume now versus lend for future consumption. Match each economic condition described below with the individual's best course of action to maximize their satisfaction.
Justification of the Optimal Consumption-Lending Choice
An individual is choosing how much of their initial income to consume today versus lend at a given interest rate for consumption in the future. They have selected a consumption plan that provides them with the highest possible level of satisfaction. At this chosen point, which of the following relationships must hold true?
An individual with an initial endowment of $500 today and no income in the future can lend money at an interest rate of 15%. After careful consideration, they choose a consumption plan that maximizes their satisfaction. At this optimal point, their personal willingness to substitute one dollar of consumption today for future consumption must be exactly ____ dollars in the future.
