Evaluating a Simplifying Assumption in a Consumer Choice Model

An economist is building a model to predict a typical consumer's purchasing decisions between two goods. To ensure the model yields a single, predictable outcome, the economist assumes that the consumer's preferences are 'convex'. In economic terms, this means the consumer is assumed to always prefer a mix of the two goods over having a lot of one and none of the other.

Critically evaluate the use of this 'convex preferences' assumption. In your response, you should:

  1. Explain the primary benefit of making this assumption from a modeling perspective.
  2. Provide and justify a real-world example where this assumption is plausible and another real-world example where it would likely be an inaccurate representation of consumer behavior.
