Justification of an Optimal Consumption Strategy
An individual determines their optimal balance between 'consumption now' and 'consumption later'. They have an initial endowment of resources, which they can either invest for a return or use as a basis to borrow against future income. Their final decision is to consume more 'now' than their initial endowment would allow, which requires taking out a loan.
A friend argues this is a poor decision because it involves going into debt. Construct an argument to justify the individual's choice as being optimal for their personal satisfaction. Explain, using the concepts of feasible frontiers and indifference curves, how borrowing can lead to a higher level of utility than a strategy that involves only saving/investing or consuming the initial endowment.

Analyzing an Optimal Consumption Choice
An individual is deciding how to allocate resources between 'consumption now' (horizontal axis) and 'consumption later' (vertical axis). They can invest their initial resources at a certain rate of return, and they can also borrow against future resources at a specific interest rate. Their optimal choice is found at the point where their highest possible satisfaction curve (indifference curve) is tangent to their expanded budget line. If this optimal point has the coordinates (95, 55), what is the correct interpretation of this outcome?
Deconstructing an Optimal Consumption Plan
Consider an individual who determines their optimal plan for spending over time, choosing between 'consumption now' and 'consumption later'. They can invest for a return and also borrow at a market interest rate. Their optimal choice occurs where their satisfaction curve (indifference curve) is tangent to their budget line (feasible frontier).
True or False: At this point of tangency, the individual’s personal valuation of an extra unit of consumption now, measured in units of future consumption, is exactly equal to the market interest rate at which they can borrow.
An individual makes an optimal choice for consumption over two periods ('now' and 'later') by both investing and borrowing. This choice is represented graphically. Match each component of the graph with its correct economic meaning.
Justification of an Optimal Consumption Strategy
An individual starts with resources only available for 'consumption now'. They have access to both an investment project and a credit market where they can borrow. To determine their optimal combination of 'consumption now' and 'consumption later', they follow a specific logical sequence. Arrange the steps below in the correct order that describes this optimization process.
An individual has an initial endowment of $200, all available for consumption in the current period. They have an opportunity to invest this entire endowment for a 25% return, making it available in the next period. They can also borrow against their future assets at a 10% interest rate. If this individual chooses an optimal consumption plan that involves spending $150 in the current period, the amount they will have available for consumption in the next period is $____.
Evaluating a Consumption-Savings Plan
An individual's optimal plan for 'consumption now' versus 'consumption later' is found where their satisfaction curve (indifference curve) is tangent to their budget line. At this point of tangency, their personal valuation of present consumption (in terms of future consumption) equals the market trade-off (the interest rate). Consider a different consumption plan, also on their budget line, where their personal valuation of an extra unit of present consumption is higher than the market's trade-off rate. To increase their overall satisfaction, what should this individual do?
