Simplifying Assumption in Lending Models: Guaranteed Repayment
In initial economic models analyzing borrowing and lending, a key simplification is the assumption that all loans will be fully repaid. This approach intentionally overlooks the possibility of default risk, thereby allowing the analysis to concentrate on other fundamental aspects of the financial transaction, such as intertemporal choice.

Consider an individual's decision between 'consumption now' and 'consumption later'. Their initial situation before any financial transaction is represented by an endowment point. They can choose any combination of consumption now and later along a downward-sloping feasible frontier that passes through this endowment point. If this individual's optimal choice results in a level of 'consumption now' that is greater than their initial endowment for 'consumption now', which of the following statements must be true?
Comparing Intertemporal Choices
Analyzing the Impact of an Interest Rate Change on a Borrower
An individual is deciding how much to consume now versus in the future. In the graphical model representing this choice, the slope of the line representing all possible consumption combinations they can achieve through borrowing or lending is determined by their personal degree of patience.
An individual is deciding how to allocate their consumption between the present and the future. Their options are represented by a downward-sloping feasible frontier, and their preferences are represented by indifference curves. At their current consumption plan, which is a point on the feasible frontier, they are willing to give up 1.05 units of future consumption to gain 1 unit of present consumption. The market allows them to exchange 1 unit of present consumption for 1.10 units of future consumption by saving. To reach a higher level of satisfaction, what should this individual do?
The Graphical Determination of Borrowing and Lending
An individual makes a choice between consumption today and consumption in the future, constrained by their initial resources and the market interest rate. Match each economic description below to the corresponding feature of the graphical model that represents this choice.

Evaluating a Simplified Financial Model
In the context of building a basic economic model to understand an individual's decision to borrow money, what is the most likely reason for an economist to start with the assumption that all loans are repaid in full, even though this is not always true in reality?
Critique of a Simplifying Economic Assumption
A financial model that assumes all loans are fully repaid is fundamentally flawed and provides no useful insights into real-world borrowing decisions because loan defaults are common.
Impact of a Modeling Assumption on the Feasible Frontier
An economist develops a basic model to analyze an individual's decision to borrow money. The model assumes that any loan taken will be repaid in full with certainty. If this simplifying assumption were to be removed to make the model more realistic, which of the following would be the most direct and necessary adjustment to the terms of the loan within the model?
Analyzing a Modeling Choice for Student Loans
An economist is building various models to analyze borrowing and lending. Each model is based on a different core assumption about whether a loan will be paid back. Match each statement describing a feature of an economic model of lending to the conclusion that can be drawn about the model's underlying assumption regarding loan repayment.
