Key ideas
Markets connect buyers and sellers
Buyers want the lowest price and best quality; sellers want the highest price they can get. The market is the meeting point — physical like a farmers' market or digital like an auction site — where their offers are matched and trade happens.
Prices emerge from interaction
If many buyers chase few goods, sellers can raise prices; if shelves are full of unsold goods, sellers cut prices to attract buyers. Haggling in a bazaar and pricing algorithms on a shopping website are both versions of this price discovery.
Key term — market: Any arrangement where buyers and sellers come together to trade — a physical place like a market hall or a digital one like an auction website.

- Thinking markets are only physical places Online marketplaces and stock exchanges are markets too — what matters is buyers meeting sellers, not the building.

Practice
A market with a single seller and no close rivals.
Price rises, as buyers compete for limited supply.
Rival firms undercut each other to attract buyers, driving prices down.
Sellers can charge a high price because demand exceeds supply.
