Lisa views pizzas and burritos as goods. If she prefers a bundle of 4 burritos and 4 pizzas to a bundle of 4 burritos and 5 pizzas, which property of consumer preference is violated? What change in the assumptions could lead a rational consumer to prefer the first bundle? What will be an ideal response? […]
