Technological Change Market Efficiency

Categories: Tech, Econ

Thanks to the internet, you don’t need to leave your house to buy most things...you can just buy them on Amazon. Reviews seem fishy? Easy...plug the item’s URL into Fakespot, an algorithm that does its best to judge how many of the reviews are legit, giving you an altered score.

When you're a buyer, you now have liquid access to vastly more information than you did before. You’re not limited to the selection of soaps on a grocery store shelf; you have the whole internet at your fingertips, plus reviews (and review police). What products thrive online or die on the vine is largely due to this access to information about the products, creating a more efficient market (at least in theory) than before the internet was a thing.

The inspection of pricing via smart-ish technology has increased market efficiency pretty much across the board. Not too long ago, stock market trading was done “on the floor” with crazy dudes yelling at each other in a flurry, with trades happening at a glacial pace. Today, we’ve got algorithms trading faster than our little human brains can even comprehend.

Like you with your soap, investors and brokerages have more information about stocks, companies, and performance than ever before. They can make algorithms with data that previously wasn’t possible. Technology has brought information and accessibility to the forefront, making the market more efficient. Still, it’s not fully efficient, especially when the information out there is asymmetric, or when people are lying. Surely you’ve seen bad reviews on Amazon complaining about how the product shipped was nothing like the picture. That’s an inefficiency right there. But ironically, them telling you the “truth” about the product is helping to create a more efficient market by informing you, another potential buyer, to maybe shop elsewhere.

Likewise, research and high-frequency trading are great for increased market efficiency...but only up to a point. If there’s too much high-frequency trading that is all reacting the same way to market changes, it can create a sudden sell-off, causing extremely quick and dramatic increases and decreases in the value of securities, not to mention glitches.

Technology might be smarter and faster than we are, but it’s got its fair share of problems as well.

00:00

And finance Allah shmoop What is technological change Well let's

00:08

see We all benefit from technology Just think about it

00:11

We're talking to you through time and space thanks to

00:14

a little thing called the Internet Yeah great No big

00:17

deal In economics technological change is used to describe anything

00:21

that increases output without increasing input In other words technological

00:26

changes magic It's anything that makes creating economic value more

00:31

efficient like the Internet and computers are tools that we

00:35

often think of when we hear technology But changes in

00:37

processes count as technology as well For instance the invention

00:41

of the assembly line and great process there was first

00:44

put into play by Henry Ford in the late nineteen

00:47

twenties and it was the key to making mass production

00:50

possible By combining the use of machines with stationed workers

00:54

and interchangeable parts Ford was able to produce far more

00:58

vehicles with the same amount of inputs as before Even

01:01

hammers wristwatches and dialogue were once leading technological change Today

01:06

we've got self driving cars flying cars three D printing

01:10

and neural network development increasing market efficiency and well yes

01:14

Granted our relationship with technology has never been straightforward in

01:18

the case of the assembly line While workers in Ford's

01:20

factories did have better working conditions In some ways they

01:23

had worse working conditions In other ways workers didn't have

01:27

to do any heavy lifting or low stooping like they

01:29

did before And there were jobs almost anyone could dio

01:33

plus the assembly line allowed for to pass on some

01:35

of those efficiency gains from technological change to workers wage

01:39

improvements Despite these benefits the turnover at Ford's assembly line

01:43

jobs was incredibly high For a while workers could on

01:46

Lee do the mind numbing jobs for so long It

01:49

was also argued by Karl Marx that doing the same

01:52

little repetitive task over and over and over again made

01:55

it difficult for workers to feel like they were actually

01:57

contributing anything meaningful in their jobs Well guess what The

02:01

turnover at Ford's factories was so high that Ford decided

02:04

to give his workers two days off working only five

02:07

days a week eight hours a day What a concept

02:10

That's right The technological change of assembly lines lead to

02:13

increased market efficiency and supreme boredom among workers which then

02:17

led to the forty hour work week who go forward

02:21

Increasingly these repetitive type tasks are being done by advanced

02:25

robots Even more creative jobs like writing for shmoop and

02:29

making music composition are now being done by robots It's

02:33

nothing personal It just makes sense for business to use

02:35

more robots If doing so allows them to doom or

02:38

with less well as technological change progresses it's increasingly a

02:42

concern that robots will take up so many jobs There

02:46

won't be many left for a human Beings will have

02:49

a huge part of the workforce just permanently unemployed then

02:52

Plus most economic gains from technological change in the last

02:54

several decades haven't ended up in workers pockets which is

02:58

kind of a concern We've always had a love hate

03:00

relationship with technological change We love how easy it makes

03:03

our lives but sometimes it makes them too easy can't

03:06

live with robots and well can't live without him What
