Evaluating a Simplifying Assumption in a Consumer Choice Model

An economist is building a model of consumer choice and assumes that the consumer's utility function is strictly concave. What is the primary economic justification for this mathematical assumption?

Interpreting a Production Model Assumption

An economist is developing a model to understand the consumption patterns of a person addicted to a particular substance. A common simplifying assumption in consumer theory is that the utility function is concave. In this specific context, why might this assumption be problematic?

Proposing a Simplifying Assumption for a Public Goods Model

In economic modeling, an assumption is considered justified if it significantly simplifies the mathematical analysis, even if it does not correspond to any plausible real-world behavior or constraint.
