An individual has an endowment of 100 units for consumption now and zero for consumption later. They have two financial options: 1) Invest any part of their current endowment to receive a 50% return later. 2) Borrow against their future income at a 10% interest rate. The individual's optimal choice is to consume 80 units now and 62 units later. Which statement accurately breaks down the actions taken to reach this optimal point?

Deconstructing an Intertemporal Choice

Consider an individual who has an endowment available only in the present. This individual has two options: they can invest their endowment for a return in the future, and they can also borrow against this future return. In a standard graphical model of this choice, a specific interpretation states that the value on the horizontal axis ('consumption now') corresponding to the individual's final optimal point represents the total amount they invested.

Analyzing an Intertemporal Consumption Choice

Analyzing an Intertemporal Consumption Choice

An individual starts with an endowment of $100, all available in the present period, and none in the future. They have an investment opportunity that yields a 50% return and can also borrow at a 10% interest rate. Their final, optimal choice is to consume $80 in the present period and $62 in the future period. Based on this scenario, the amount the individual invested is $____.

An individual starts with an endowment of $100 for consumption now and $0 for consumption later. They have two options: invest for a 50% return, and borrow at a 10% interest rate. Their final optimal choice is to consume $80 now and $62 later. To achieve this, the individual invests their entire initial endowment and then borrows against the future proceeds. Match each economic concept with its correct numerical value from this scenario.

An individual begins with an endowment entirely available in the present and has opportunities to both invest for a future return and borrow against that future return. Arrange the following actions in the logical sequence that describes how this individual moves from their initial endowment to their final, optimal consumption bundle.

Critiquing an Interpretation of Intertemporal Choice

An individual has an endowment entirely in the present period. In a standard intertemporal choice model, point K represents their optimal consumption bundle when they can only invest. Point L represents their optimal bundle when they can both invest and borrow. What is the correct interpretation of the horizontal coordinates (representing 'consumption now') for these two points?
