Lesson 4: Capacity utilization and inflationInflation, deflation, and capacity utilization 2
The role of capacity utilization and the potential for deflation is explored in more depth. Created by Sal Khan.
Want to join the conversation?
- If unemployment is just a measure of capacity utilization, then theoretically if we aren't using our full capacity shouldn't we lower "prices" to raise demand? By this I mean isn't it logical to lower minimum wage to get companies to start hiring again in order to bring us back to a normal consumption/investment economic model?(16 votes)
- If you have .8/1 million working at %100 minimum wage, and lower the min wage to 90% to allow .9/1 million working you still do not have any change in the volume of money, unemployment would decrease but there would be no change in aggregate demand, nor capacity utilization, nor consumption/investment.(8 votes)
- Sal sells seashells by the shore. If the money supply increases doesn't this devalue the currency and that's what increases the price? The inflation is then not in price but in the supply of money.(4 votes)
- Yes, that will happen - but it might not happen immediately. In the short term, people might hoard money instead of spending it, so you don't see any inflation. However, in the long term, yes. Increasing the money supply will always increase prices unless that money gets hoarded forever. Nobody hoards money forever, and those that do tend to invest it, so it enters the economy anyway.
I'm not sure why Sal doesn't address this.(3 votes)
- 6.06 borrwing the money from the other coubtry and usingnit to buy their goods..i do t get that part. Can't we borrow money and use it in anyway we want to use it? Help me out here.(1 vote)
- Not exactly. The lender will probably want to know what you are going to use the money for, so that the lender knows that he or she will be paid back, but if the lender is reasonably sure that he or she will be paid back, then you will get the money.
However, that is not what Sal atwas talking about. He was talking about the fact that we were giving them dollars in exchange for their output. When we give another country (which doesn't use the dollar) a dollar, that is basically a promise that they can spend it in the United States later. So basically we are borrowing their output, and the dollar is just an IOU saying that we owe them some of our own output. 6:06(6 votes)
- At, Sal talks about borrowing money/goods from the chinese. How can I imagine somthing like that, who is borrowing from whom exactly? 5:58(1 vote)
- When you buy something that was made in China, someone in China gets your dollars, and you get a piece of merchandise. That person in China might not want to hold dollars because she can't spend them in China, so maybe she exchanges them for Chinese currency, but then someone else in China has the dollars. So unless someone in China is going to use the dollars to buy something from the US, and pay in dollars, there are going to be extra dollars in China, until they decide to spend them.
If you add this up across the whole economy, what it means is that there are a lot of dollars in China. What should those people do with them if they don't want to buy merchandise from the US right now? They can instead buy US government bonds, which will pay them interest.
Anyone who buys a bond is essentially holding a loan made to the US government. So ultimately what has happened here is that the US has taken goods from the Chinese, and the Chinese have been paid with interest bearing securities instead of non-interest bearing dollar bills.(5 votes)
- If consumption goes down then people have the fear of loosing all their money, so they do not spend it which makes unemployment go up and then nobody is selling anything right? Then why are prices going up instead of going down? Or are people just assuming that even if they lower their prices nobody is going to buy anything so they just increase their prices and take more money from the people that are actually consuming?(2 votes)
- prices are going up because of the increase in money supply.the government is keeping interest rates low so that they could sustain that demand which existed before.thus everytime that capacity utilisation decreses the government steps in and gives people cheaper credit so that people could continue buying those goods
thus they keep pushing up prices(2 votes)
- Towards the end, Sal mentioned that the Government's start borrowing money through loans because no one else can to try and fill up the gap in consumption, which is the purpose of the Obama trillion dollar stimulus plan. Why can't the government just spend money from the federal reserve for the stimulus? Why take a loan when they themselves have so much moeny? Why not loan that money to banks so Lehman Brothers wouldn't have failed, as the money would give them liquidity.(2 votes)
- SO, basically, if not enough people buy things, then we lose money. If we buy too much stuff, then we go into other countries debt. Is there a special amount of money we should be spending annually, as a country, so that our national debt is very low, and we are well off?(2 votes)
- So, does a low velocity leads both to inflation or deflation? There is something I've not quite understood. If there is a low velocity, people stop spending and selling. So the few people willing to buy or sell money would have to pay higher amounts in the first case or sell for far lower prices. Is it deflation or inflation?(1 vote)
- The equation is mv = pY
m is money supply
v is velocity
p is price level
Y is GDP
You can see that if v goes down AND ALL ELSE IS EQUAL then p must go down, which means deflation
But all else is rarely equal(2 votes)
- Sal, how do interest rates and investment affect utilization? If there is an effect, wouldn't monetary policy play a significant role?(1 vote)
- Interest rates and investment do play a role. The lower the interest rates, the greater the investment. There are two things which investment will do. It will make it cheaper to produce goods, and so more goods will be produced, and it will increase the capacity. Normally, that will result in inflation, but not for either of those reasons, which tend to cancel each other out. The real reason is because consumers can also borrow more easily with lower interest rates, driving up demand.(2 votes)
- In the case of monetary inflation, how does the extra money printed by the central bank enter the economic system?(1 vote)
- The central bank uses it to buy government bonds.(1 vote)
Video transcript
In the last video I spoke a
bunch about the determining factor on whether we have
inflation or deflation. It isn't so much the money
supply, although the money supply will have an effect,
it's really capacity utilization. Capacity utilization is
driven by demand. And I made that distinction
because-- I gave that example of the island, where you could
have a very small money supply, for example, one
seashell, but if the velocity is really high, then people are
expressing that demand. And you'll have very high
utilization of all of the capacity in the island and you
might have inflation, even though the money supply
is one seashell. On the other hand, let's say, we
found a bunch of seashells, but everyone stops transacting,
so the velocity were to slow down a bunch. So in that case, even though the
money supply is huge, or a lot larger than it was, people
aren't expressing demand. So demand will be a lot
lower than capacity. As we showed in the cupcakes
economics video, when you have a lot of unused capacity, it's
everyone's incentive to try to sell that extra unit and
they all lower prices. So you can have an increased
money supply but, if the velocity slows down or if
demand is slowing down-- because that's what's causing
the velocity to slow down-- then you could still have a
deflationary situation. Actually, we touched on the
chart where we showed that every major inflationary bout
was actually stimulated, or was actually preceded, by a
pretty big upturn in capacity utilization. And the inflation really started
going once capacity utilization got into
the 80% range. You could imagine that if, on
average, the world is running at 80% that means that some
people are running at 70%, some people are running
at 90%, 95%. And those people who are running
at 95%, those are the people who say, gee, instead of
trying to run at 96%, 97%, 98% utilization, why don't I
just raise price and not have to worry about producing
that extra unit? And obviously their inputs go
into other people's; their outputs go into other
people's inputs. And then you get a generalized
price inflation. Now with that said, actually, I
want to make another point. In the early `70s-- everyone
always talks about the oil shock. In 1973 you had the
Yom Kippur War. We resupplied Israel, and then
you had all the OPEC countries that essentially stopped selling
oil to the U.S. and a lot of other western nations. And people say, you know, oil
prices shot through the roof and that's what drove inflation,
that supply shock. That probably contributed
to it, but 1973 is right around there. So if you actually look at this
chart, we're already kind of on an inflationary
spectrum. The generalized prices were
already increasing. And capacity utilization had
really preceded that. That probably just added
fuel to the flame. With that said, the question
that everyone's wondering about is, what's going
to happen now? So before the current financial
crisis, we had a certain amount of capacity. Let's say this is everything,
this is the U.S. output. Let's say this is
U.S. GDP, right? GDP is just output. So in a normal developed
environment, so that you go back into the `60s-- and I
should probably get the Bloomberg chart on this too,
because it's pretty interesting-- about 60% of our
GDP was on consumption. And consumption always
isn't a bad thing. Consumption isn't always
a bad thing. It's actually what
we use to have a good standard of living. If I have a nice sofa, and a TV
set, and I go on vacations, that's consumption. But it improves our standard of
living and the goal of all countries is really
to improve that average standard of living. But the remainder is savings. In a traditionally responsible,
developed nation you save 40%, maybe 30% to
40%, depending on whether you're Japan or whether
you're Western Europe. Now what savings turns into, is
essentially new investment to raise your ouput. So this savings is what allows
you to increase your output in the next year. If you don't save even a little
bit, your output will actually decrease, because no
one will invest in factories and the factories will get old
and the roads will stop being usable and all the rest.
Whenever someone's investing, that's someone else's savings. And it's very important to
realize that investment and savings are really two sides
of the same coin. If no one's saving, then
there's no money for investment. But just going back to this
example, when people are saving that's what not only
maintains output, but actually increases total output. So this would be in the next
year or the next decade. And then, when we consume 60%
of this, we're consuming 60% of a larger number and our
standard of living will go up. And this is a very sustainable
and good situation. What happened, unfortunately,
really since the early `80s, is that we had a constant
expansion of credit. We started lending more and
more money to everyone and other countries started
lending more and more money to us. And most of that got expressed
in more and more consumption. So if you look at U.S.
output-- This is GDP. If you actually go to 2007, the
average American consumed more than we produced. We had a negative savings. If I were to draw that,
it looks like this. In 2007, consumption was larger
than our total output. So the question is, how
did this happen? Everyone talks about money
and currencies. Essentially we borrowed output
from other people. When we borrow money from the
Chinese, which we use to buy their goods, we're essentially
just borrowing their output, right? We're borrowing their goods. So when we give them a dollar
bill, that's a promise that, in the future, they could use
that dollar bill to come back and use some of our output. But over the course of the last
several decades, we were just borrowing other
people's output. And we became net debtors. So when your consumption is
actually larger than your output, you immediately start
to realize that this isn't a sustainable situation
for too long. And maybe we borrowed a little
bit more money and, actually it did turn out that way, that
we borrowed some people's output even more to fuel some
of our investment as well. It's not like no investment
was going on for the last 20, 30 years. We had a lot of investment. But essentially, the consumption
and investment was being financed by other
people's output. And, of course, when you have
consumption touching up against-- you're fully utilized,
that makes it even more an incentive to invest.
So all of these people were willing to invest in the U.S. What happened now is, you
realize that a lot of the financing or a lot of the debt
that was being taken on, it was being facilitated by
people's homes and home equity loans but people really
aren't good for it. And now all of a sudden, the
banks dried up, liquidity is gone, people can't borrow
money, and you have a demand shock. So what you have is a situation
where a considerable amount of this consumption, and
actually a considerable amount of that investment that
was being fueled by financing, disappears. And now that we're in a global
world, we really should think about global output. But it doesn't matter,
we could talk about just U.S. output. But now that this demand has
disappeared-- if this is U.S. output and let's say, this is
output that we were taking from China or Japan or wherever
else-- and our consumption has now
fallen down here. And it's not because, all of a
sudden, people became prudent. It's because people aren't
willing to lend them, to go to Williams-Sonoma and buy a $50
spatula or whatever else. They just can't get another
credit card loan or a home equity loan. So you have the situation
now, where you have low utilization. And this comes back
to what we talked about in the last video. That when you have low
utilization, it's everyone's incentive to lower prices. When you have a bunch
of vacant houses, people lower rents. When the car factories are
empty, people lower the price of car factories. When people are underutilized,
wages go down. You see this shock, more
recently, right here. As we said in the last video,
the orange line is U.S. capacity utilization. And it dropped from about
the 80% range. If it had gone up here, I would
have started getting worried about hyperinflation. But, you see, right around
summer of 2007 it dropped off of a cliff and it's down
here someplace. Now you see a little bit later,
inflation dropped. So that dynamic that we've been
talking about, capacity utilization falling off, because
we essentially had a demand shock. And then that's led to
a decrease in prices. So the question is, everything
that the Treasury is doing, and the Fed is printing money,
and Obama spending a trillion-dollar stimulus,
is that going to lead to inflation? My answer is, just watch the
capacity utilization numbers. And, just you know, the stimulus
plan, the whole idea about it is, the government
doesn't want us to enter into a deflationary spiral. If consumption drops like this,
we have all of this capacity and prices go down. If prices go down a little
bit, it doesn't affect people's behavior
in aggregate. But if people start having
expectations that wages will go down, that prices will go
down then, they all go into panic mode and they
stop spending. Let's say they stop spending,
then utilization goes down even more, then unemployment
goes up even more, and this also makes fear go
up even more. Unemployment going up and fear
going up makes people stop spending even more. And this is that deflationary
cycle that all the economists and all of the government
officials are afraid of. You saw that during the
Great Depression. Let me draw a zero point
to show you where. That is zero. That's the dividing
line between inflation and deflation. You see we've had a couple
of bouts of deflation. And they normally aren't good
times in the world. This is the Great Depression
right here. This is post World War I, and
the Great Depression actually lasted all the way until-- we
entered the war in the late `30s-- right about
here to here. We had a little bit
of inflation. You had the first wave of the
New Deal stimulating some spending, but it really never
got us to any significant level of inflation. Just so you have a sense, I
would consider anything above 5% inflation as really,
really bad. And let me draw a line there. So that's the 5%
inflation mark. So we really didn't get above 5%
inflation until you end up with World War I, and then you
have the postwar period, we're under Bretton Woods, and then
in the `70s we had, as I talked about before, the oil
shock and all of the rest. The rest is history. But as you see, the deflationary
periods are things that government officials
want to avoid altogether. So the idea of the stimulus is
for the government to borrow money, because no-one
else can. And they can essentially fill
up the gap where the consumers left off. Now the question is, are
they going to fill up enough of a gap? Actually I realize that I'm
running out of time again. I don't like to make these
videos too long, so I'll talk about that in the next video.
