- Alcohol and gum are suggested to be unrelated by one participant.
- Margarine and butter are proposed as substitutes.
- One participant questions the term "case elasticity" and suggests it may refer to "cross elasticity."
- There is uncertainty regarding whether coffee and tea are indeed complements.
- Another participant expresses confusion about the relationship between the signs of cross elasticity and the classifications of goods.
- A request is made for definitions of "complements" and "substitutes" to clarify the discussion.
Areas of Agreement / Disagreement
Participants do not reach consensus on the classification of coffee and tea, and there is uncertainty regarding the definitions and implications of cross elasticity.
Contextual Notes
