Information Asymmetry and Adverse Selection
Used car sellers know vehicle defects buyers cannot observe, causing buyers to offer only average prices that drive quality cars from the market. This information asymmetry means only low-quality lemons remain, reducing consumer surplus and creating market underprovision of quality goods.
This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.

the one idea
why this one carries the topic.
Markets work until they don't, and economists have named every way they break. Spot which break you're looking at and the fix picks itself.
When one party has more information than another in transactions, markets can collapse as buyers lower prices to protect themselves and sellers of quality products withdraw.
what examiners catch — Students often confuse adverse selection with moral hazard; adverse selection occurs before the transaction due to hidden information, while moral hazard occurs after due to hidden actions.
what you leave with
three things, not forty.
Principal-agent problems arise when agents pursue self-interest against principal interests due to information gaps
Moral hazard occurs when insured parties take excessive risks because they do not bear full consequences
Government intervention through mandatory disclosure laws, licensing requirements, and quality standards reduces information failures
what's underneath
nothing here is a standalone fact.
knowhere maps every concept to what it rests on and what rests on it — 1 underneath this one, 0 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
