Investment Multiplier

  

Ever hear those statistics about how much money we’d save if we did preventative measures (things like brushing our teeth and, uh, getting an annual check-up)? If each of us ate an apple and walked for 30 minutes a day, we’d save gazillions in dollars via fewer people going to the doctor for heart problems...that kind of thing.

The investment multiplier carries the same idea, but re: investing money, instead of in your health. The investment multiplier refers to the magnitude of the impact of an increase in investment spending (public or private—doesn't matter) on the economy.

The idea is that investments aren’t just going toward the actual investment; they also ripple outward through those investments. For instance, renovating a rundown property downtown—with investments—turns the property into a functioning business, which provides jobs and stimulates spending and the economy in the area.

The investment multiplier tries to measure the aggregate "ripple effects" of the initial investment. Of course, how much more money people will spend depends on their marginal propensity to consume, so sometimes the investment multiplier can have more dampened effects than The Fed would like.

and finance Allah shmoop What is an economic multiplier All

00:08

right people To understand how injections of investments in cash

00:12

affect the economy macroeconomist often turned to the keen Zeon

00:15

idea of the economic multiplier Every time you spend a

00:19

dollar well that dollar eventually becomes someone else's income Likewise

00:24

every dollar you get was once someone else's income that

00:28

they spent The more we all spend in dollars while

00:32

the more dollars we all have to spend every time

00:35

Dollars which hands While that's a ching that stimulates even

00:38

Mohr Chuck Ching's in the economy this money going around

00:41

around as referred to as the circular flow of income

00:45

and in theory more spending and investment leads to even

00:49

more spending and investments It's kind of a domino effect

00:52

which ripples outward into the entire economy boosting output GDP

00:56

and employment well The economic multiplier measures how a change

01:00

in aggregate demand affects nationwide output Usually GDP like that's

01:05

the big measure through the ripple effect of the circular

01:08

flow of income Well as demands for goods services and

01:11

investments rise more money is flowing through the pipes of

01:13

the economy raising GDP and increasing economic growth Yeah Ching

01:17

city When demand for goods services and investments fall the

01:21

reduction in money flowing through the pipes contracts the economy

01:24

making GDP slow down to a trickle or even go

01:27

negative Sometimes when the economy slows down the Fed a

01:30

k a The Federal Reserve or the U S Central

01:32

bank may decide to lower interest rates Lowering interest rates

01:36

means things like business loans car loans credit cards stuff

01:40

mortgages and other types of debt are then cheaper in

01:43

theory encouraging consumers to borrow more Lowering interest rates the

01:47

equivalent of the Fed putting debt on sale which draws

01:50

in investors and spenders who then use that money spurring

01:53

more spending hopefully from their spending raising interest rates has

01:57

the opposite effect Reducing the demand for investing been spending

02:00

since is more expensive than to rent money Well for

02:03

instance let's say the Fed lowers interest rates Around the

02:05

same time Farmer Frannie was thinking about expanding her chicken

02:09

business Farmer Franny decides that taking out the loan is

02:13

worth it since she only has to pay one point

02:15

five percent interest on it Farmer Franey then uses her

02:18

loan to build Mohr chicken coops increasing the income of

02:21

the local farm outlet store and making room for Mohr

02:25

chickens to be grown and more eggs and more feathers

02:28

for beds Well some of those eggs turn into chickens

02:30

and some chickens have more eggs and to say which

02:33

came first Well farmer friend he's selling chickens and eggs

02:36

left and right and she easily pays off her really

02:38

inexpensive loan Now friend he has more money than she

02:42

would have had before which she then spends Will those

02:44

dollars travel and become other people's incomes creating Mohr economic

02:49

growth Eventually Farmer Frannie's farming business is doing well enough

02:52

that she takes out a loan to expand her farm

02:54

even further buying up the latest in farming equipment and

02:58

hiring more workers Tio take care of the whole thing

03:01

Well Farmer for any second loan puts money in the

03:03

pocket of the landowners she bought The land from right

03:06

also spends money on the companies selling to her the

03:09

new farm equipment and the incomes of her new employer

03:12

That money keeps branching outward into the economy Is it

03:15

continues this circular ripple effect like a pebble in a

03:18

pond to be spent turning into someone else's paycheck or

03:21

business investment And of course the money will only continue

03:24

to ripple outward if people keep spending it well Factors

03:27

like taxes consumer confidence in the economy and government spending

03:31

can determine how strong those ripples are how strong that

03:35

economic multiplier is at any given time for instance consumers

03:39

also have varying propensities to consume and safe depending on

03:43

how much well they're paying Tax high taxes might make

03:46

people buy less usually does just because taxes cut into

03:49

their buying power which would lower the economic multiplier Right

03:53

Well don't get too excited about all this The economic

03:55

multiplier isn't necessarily a good argument for the reason your

03:59

tax bill should be lower If taxes air low making

04:02

government revenue low well then the government may find itself

04:04

borrowing money from abroad And all that can cause interest

04:07

rates to rise over time reducing demand for investment and

04:11

spending in reducing the economic multiply right well another important

04:14

factor that affects the economic multiplier imports Yeah imports The

04:18

more money that's being spent in foreign markets will the

04:21

more that's leaking out of our national income producing our

04:25

economic multiplier of the home country U S A U

04:29

s A and our GDP when there's a change in

04:32

taxes or interest rates or confidence in the economy Well

04:35

the multiplication effects kind of lesson all right But in

04:38

the long run economists expect things like reduced interest rates

04:41

tax cuts stimulus packages and renewed confidence in the economy

04:45

to have positive multiplier effect OK now get out there

04:48

and spend knowing that every dollar you spend is contributing

04:51

to someone else's income in the short run and the

04:53

economic multiplier in the long run Yeah way to be 00:04:55.887 --> [endTime] a team player by that portion
