After a city government guarantees it will cover all financial losses for any new restaurant that fails within its first year, several new restaurant owners begin to take significant, unobservable risks with their business models, such as using overly expensive, low-demand ingredients. This change in behavior, driven by the financial safety net, is a classic example of a(n) ____ problem.

Model Prediction vs. Real-World Borrowing

A basic economic model predicts that a rational individual with high expected future earnings but no current savings will choose to borrow a large sum for a valuable investment today. However, in practice, this individual is often unable to secure the loan. What is the most likely reason for this discrepancy between the model's prediction and the real-world outcome?

The assumption that individuals can borrow without initial wealth makes basic lending models entirely useless for understanding any real-world borrowing behavior.

The Rationale for Simplifying Assumptions in Economic Models

In a standard intertemporal choice model, an individual has no wealth today but is guaranteed a large income in the future. If we introduce the real-world constraint that lenders often require collateral (initial wealth) to issue a loan, which component of the individual's decision-making model is most directly and immediately restricted?

Critiquing a Simple Lending Model

An economic advisor uses a standard model to argue that a new government program offering free business plan workshops will significantly boost new business creation. The model assumes individuals can borrow against their expected future profits. A critic argues the program will have little effect on aspiring entrepreneurs from low-wealth backgrounds. What is the most likely foundation for the critic's argument?
