Evaluating a Model's Prediction
A simple economic model of intertemporal choice predicts that if the market interest rate falls, all individuals will choose to borrow more to increase their current consumption. In two to three sentences, explain a key reason why this prediction might not hold true for a significant portion of the population in the real world.

Assessing the Real-World Applicability of Credit Models
A simple economic model of borrowing assumes an individual can freely borrow or lend at a single market interest rate to choose their preferred mix of consumption now versus consumption later. Which of the following real-world situations represents the MOST significant deviation from this model's core assumptions?
Applying Economic Models to a Real-World Scenario
Simple economic models of borrowing and lending make several simplifying assumptions. Match each of the following real-world scenarios to the specific limitation of the simple model that it best illustrates.
A simplified economic model of borrowing assumes an individual can freely borrow any amount at a single market interest rate. According to this model's logic, if it accurately predicts the borrowing choices of a high-income individual, it must also accurately predict the choices of a low-income individual, since the basic trade-off between consuming now versus later is universal.
Model vs. Reality in Lending Decisions
A government analyst uses a simplified economic model which assumes that all individuals can borrow or lend any amount they wish at a single, fixed interest rate. Based on this model, the analyst concludes that a government-mandated, universally available low-interest rate loan will completely solve the problem of individuals being unable to afford major purchases. Which of the following statements provides the strongest critique of the analyst's conclusion by identifying a critical omission in the model?
Evaluating a Model's Prediction
The primary limitation of simple economic models of borrowing and lending is that they fail to account for individuals' irrational psychological biases when making consumption decisions over time.
