What is a consumption bundle?
A specified combination of goods, such as a particular number of apples and cookies.
Why can’t an indifference curve slope upward when more of both goods is better?
If more of both goods is better, an upward-sloping curve cannot represent equal preference: moving upward would add both goods.
What does completeness of preferences require?
For any two bundles, the consumer can rank one at least as highly as the other, or regard them as equally good.
What does an indifference curve represent?
The set of all bundles that a consumer regards as equally good.
What do convex preferences mean?
A preference is convex when mixtures of two equally valued bundles are at least as good as either bundle.
What does monotonicity, or “more is better,” mean?
More of a good, with other goods unchanged, is preferred.
What is local nonsatiation?
However close a bundle is, there is always a nearby bundle the consumer prefers. This condition is weaker than requiring every good to be desirable in every circumstance.
What does continuity of preferences mean?
Small changes in bundles do not produce abrupt reversals in ranking. Under standard conditions, continuity supports a utility representation.
What does A ⪰ B mean?
Bundle A is at least as good as bundle B.
When is A strictly preferred to B?
A is weakly preferred to B, but B is not weakly preferred to A.
What does it mean for a consumer to be indifferent between A and B?
The consumer weakly prefers each bundle to the other: A⪰B and B⪰A.
What does transitivity of preferences require?
If A⪰B and B⪰C, then A⪰C.
