An individual has an initial endowment of 100 units of a good for consumption today and none for consumption tomorrow. They have an opportunity to invest any portion of today's good for a 50% return, meaning for every 1 unit invested, they receive 1.5 units tomorrow. The individual's optimal choice is to consume 60 units today and 60 units tomorrow. At this optimal point, what must be true about the relationship between their personal valuation of present versus future consumption and the investment's rate of return?

Optimal Consumption-Investment Plan

Evaluating an Optimal Consumption-Investment Plan

An individual starts with an endowment of 100 units of a good for consumption today and zero for consumption tomorrow. They can invest any portion of this endowment for a 50% return, meaning 1 unit invested today yields 1.5 units tomorrow. If this individual's optimal plan is to consume 60 units today and 60 units tomorrow, it implies that at this specific consumption bundle, their personal willingness to trade future consumption for an additional unit of present consumption is greater than the 1.5 rate offered by the investment.

Calculating Optimal Consumption

An individual starts with 100 units of a good for consumption today and none for tomorrow. They can invest any portion of today's good for a 50% return (1 unit invested today yields 1.5 units tomorrow). Their optimal plan is to consume 60 units today and 60 units tomorrow. Based on this information, match each economic concept to its correct numerical value.

Analysis of an Optimal Intertemporal Consumption Choice

An individual has an initial endowment of 100 units of a good for consumption today and zero for tomorrow. They can invest any portion of this endowment for a 50% return, meaning 1 unit invested today yields 1.5 units tomorrow. Their optimal consumption plan is found to be 60 units today and 60 units tomorrow. Consider an alternative feasible plan where they consume 80 units today and 30 units tomorrow. Why is this alternative plan not optimal for this individual?

An individual has an initial endowment of 100 units of a good for consumption today and zero for tomorrow. They have an opportunity to invest any portion of this endowment for a 50% return. Their optimal choice is to consume 60 units today and 60 units tomorrow.

Statement: True or False: Given this information, if the individual were instead to consume all 100 units of their endowment today, they would achieve a lower level of utility compared to their optimal choice.
