Implications of a Model's Assumption
In an economic model comparing the consumption choices of two individuals over time, it is often assumed that both have identical tastes and desires. If this assumption were removed, and the individuals were allowed to have different preferences, explain what new factor—aside from their initial resources and investment opportunities—would need to be considered to understand the differences in their consumption patterns.

In an economic model comparing the choices of two individuals with different initial resources, assuming they have identical preferences makes the model's conclusions invalid for real-world situations where people's tastes differ.
An economic model compares the consumption decisions of two individuals over two time periods. One individual starts with a large amount of a good but no opportunity to produce more, while the other starts with no good but has a productive opportunity. The model concludes that their different starting conditions lead them to choose different consumption patterns. If the model's creators were to relax the assumption that both individuals have identical tastes and desires, what would be the main analytical difficulty this creates?
In an economic model that analyzes the consumption choices of two individuals with different financial circumstances, various assumptions are made to structure the analysis. Match each model assumption or condition with its primary analytical purpose.
In an economic model designed to isolate the impact of different financial opportunities on consumption choices, assuming that all individuals have identical preferences is a simplifying technique. If this assumption were removed, it would become difficult to determine whether differences in consumption are due to financial circumstances or to variations in individual ____.
Interpreting Model Discrepancies
An economic model examines the choices of two individuals who have the exact same income and face the exact same prices for all goods. Despite these identical financial circumstances, the individuals choose to purchase and consume very different bundles of goods. What is the most logical conclusion that can be drawn from this observation within the framework of the model?
