So here we have the talk about elasticity, and let's remember what the definition of elasticity is.
00:06
It's the percent change in quantity over the percent change in price.
00:10
So when we're thinking more elastic, more inelastic means we have to make this smaller, right? we want to make qd small.
00:24
Because if qd moves a lot, the product is elastic, right? price changes in quantity demand it moves a lot so we want to make quantity demand it small and to change very little that's what inelasticity means so um more substitutes is going to be wrong to clearly wrong right because more substitutes makes it easier to switch when there are substitutes you can say look when the price rises i don't want to buy this good anymore and i can get something else right substitutes make switching easy and that means when the price goes up people will switch to those substitutes right so um this one is going to be wrong the correct answer here b is brand loyalty i won't switch right um now if i am brand loyal when the price goes up um no change in quantity if i insist on buying a particular brand regardless of the price, this is the definition of inelasticity, right? the price changes, and i keep buying the brand that i'm loyal to, right? so this reduces switching, right? and elasticity is all about switching.
01:47
It's all about changing.
01:48
So this person changes their purchasing behavior less.
01:51
That makes them more inelastic, right? c, time.
01:58
Time is wrong because...
