So when we're thinking about competition, let's imagine this situation.
00:04
Competition, you have many firms competing over price, right? it's a large market where many firms compete, as opposed to like a monopoly where you only have one market, right? so if price falls, what i would actually expect to happen is many people will want to buy.
00:31
Will want to buy from larry, right? it's like a gas station.
00:37
Imagine that your town has 100 gas stations, and then one gas station suddenly announces that they're selling gas at 50 % off.
00:44
That gas station is going to get really, really popular, really, really quickly, right? so i would expect massive increase in quantity, right? just like the gas station that's cutting its prices, right? this is why in a competitive market, price is equal to marginal cost, right? if you try to price high, nobody will buy your product.

If you try to price low, you'll sell a million units at a loss.
01:16
The only sustainable equilibrium is for you to price at your marginal cost...
