Price Sensitivity

  

Categories: Econ

See: Inelastic Demand. See: Elastic Demand.

Hmmm...you were going to buy that bus ticket, since it’s cheaper than a flight, but it costs more now. Maybe you should see how much the train costs.

Hold up. Let’s dissect what just happened...like an economist. You looked up the price of a bus ticket, and decided it was the best option at the time. But you didn’t buy (for shame, for shame!). Later, you expected the bus ticket price to be the same, but it wasn’t. It went up. This got you thinking about alternatives...substitute goods, if you will.

This is price sensitivity at work. Price sensitivity is how consumers change their behavior in accordance with price changes. Prices go up, and demand goes down...everyone runs away. Too expensive, they say. Prices go down, and everyone flocks...too much demand and not enough supply makes for a dangerous shopping experience. In these cases, there is high price sensitivity.

But it’s not always like that. Sometimes, the price for something will go up, and there will be the same demand, regardless. Economists measure price sensitivity with the price elasticity of demand. A high elasticity means a high price sensitivity; “inelastic” means people aren’t responsive (i.e. sensitive) to changes in prices.

What would you keep buying even if the price went up?

Econ: What is Income Elasticity?14 Views

00:00

and finance Allah shmoop What is income Elasticity All right

00:07

people when you get a pay raise you feel like

00:10

you're on top of the world King of a fatter

00:13

wallet With all that dough you're starting to feel more

00:15

flexible Income elasticity also known as income Elasticity of demand

00:21

is a way to measure how changes an income change

00:23

Consumer demand like incoming elasticity is calculated by taking the

00:28

percent change in demand Numinous old over old and dividing

00:32

it by the percent change in income Yeah that's what

00:35

it looks like So back to that pay raise of

00:37

yours as income rises while we can expect to see

00:40

the demand for normal goods to rise Actually that's kind

00:43

of the definition of normal goods like normal goods aren't

00:46

things you normally buy right there Just goods you want

00:50

more of when you have more money in your pocket

00:53

A normal good for you might be gourmet coffee I

00:56

gotta love that For your sister a normal good might

00:59

be more quality fashionable clothes with intentional holes ripped in

01:04

them for your weird uncle Well more income might mean

01:07

artistic statues in his backyard Yeah to each his own

01:11

But as long as you start demanding more of a

01:13

good in response to more money to pay for it

01:15

you then have a positive income elasticity for that good

01:19

which means it's a normal good For instance let's say

01:22

you got a ten percent raise which caused you to

01:24

buy five percent more coffee Well that would mean five

01:27

percent increase in demand divided by ten percent increase in

01:29

income or a positive income Elasticity of demand of a

01:33

positive point five Yeah we can smell the freshly ground

01:36

Kona right now Well let's say that a month later

01:39

your boss said psych no raise for you Bummer Well

01:43

we'd simply switch the signs It's negative five percent then

01:46

divided by that negative ten percent Ten It's still equals

01:49

a positive zero point five incoming elasticity on a graph

01:53

where quantity demand it is on the X axis right

01:56

there and income is on the Y axis well normal

01:59

goods r sloping upward The more money we have the

02:02

more of that normal good will want to buy And

02:04

the opposite of normal goods are in theory your goods

02:08

which our goods that have a negative income elasticity like

02:11

inferior goods or goods You can live without my goods

02:14

You demand less as income rises It may or may

02:17

not be true for you but for many people fast

02:20

food is an inferior good right Not because it's made

02:23

out of chicken parts in the intestine and pig hooves

02:26

but because it has negative incoming elasticity Like remember when

02:30

your boss took back that pay raise will it meant

02:33

less gourmet Kona coffee a normal good and mohr fastfood

02:37

coffee and inferior good Well the initial ten percent pay

02:40

raise had led to an eight percent decrease in your

02:43

consumption of watery Mickey D's coffee So then you calculate

02:48

the net number to you as a negative eight percent

02:51

They're divided by a positive ten percent so that gives

02:54

you a negative zero point eight income elasticity When your

02:58

boss took back to pay raise grumble grumble your income

03:01

went down and consumption of bitter burn fast food coffee

03:04

went back up positive Eight percent divided by negative ten

03:08

percent is negative point eight Okay well on the graph

03:11

inferior goods or downward sloping The more money we have

03:14

the less you know french fries that we really want

03:16

to buy What about goods you buy the same amount

03:19

of no matter what your income like things like water

03:22

and toilet paper Well on the graph If the queue

03:24

stays the same regardless of a change in income than

03:27

the curve for that good would be a straight line

03:30

upward Twenty percent raise ten percent pay cut Doesn't matter

03:34

Still the same amount of toilet paper demanded That makes

03:36

our percent change in demand on top zero since well

03:40

there was no change if you went from buying one

03:42

bundle of TP before a raise and one bundle of

03:45

TP after a raise Yeah it's a change of zero

03:48

and zero divided by anything in California and any other

03:50

state in the nation is zero Which makes sense since

03:53

the line is vertical But hey what about luxury goods

03:56

Well as it turns out luxury goods or just a

03:58

type of normal good except more expense usually a luxury

04:02

good is a normal good because it has a positive

04:04

income elasticity What makes it different Well it has to

04:07

have an incoming elasticity greater than one For example let's

04:11

say a ten percent increase in your weird uncles income

04:13

resulted in a twenty percent increase in demand for his

04:16

weird yard art In our formula that would mean positive

04:20

Twenty percent is on top and positive Ten percent is

04:22

on the bottom for an income elasticity of two Well

04:25

think about what an incoming elasticity of at least one

04:29

means Your increase in demand for good must be the

04:32

same as the increase in your income or greater What

04:35

makes luxury goods luxury is being able to afford to

04:38

buy more of something than the proportion of your increase

04:42

in income Well there are a lot of things you'd

04:44

rather by then those odd things your uncle is decorating

04:47

his yard with but well different strokes for different folks

04:50

As they say luxury is in the eye of the 00:04:52.965 --> [endTime] consumer here
