See: Purchase Power Parity. See: Relative Purchase Power Parity.
Relative form purchase power parity, better known as relative purchase power parity, is regular purchase power parity (PPP) on steroids...dynamic steroids.
Regular PPP is a way to measure the exchange rate between two different currencies. PPP is when you take two identical goods and compare how much they cost under one currency, like the U.S. dollar. For instance, you can buy some $10 dumplings in the U.S., and buy almost identical dumplings in Thailand for 150 baht, or about $5 USD. Repeat this process with baskets of goods like transport, food, and healthcare, and you’re a PPP master.
Relative form PPP gives us even more information, since it takes the changing inflations of both currencies into account. If you take regular PPP at its word, you’re kind of ignoring inflation, or assuming that it’s the same in both currencies.
Take Venezuela for instance: the bolivar hyperinflated by 42,000% (that’s not a typo). If you took the PPP right before that happened, and right after, you’d get two very different numbers.
This is what relative form PPP avoids by taking inflation into account. It implies that, as inflation goes up, the value of that currency compared to the other goes down.
Let’s say you were able to buy coffee for 500 bolivars, and it now costs 220,000...yet over the same period of time in the U.S., coffee went from $2 to $2.15. Now, you need a lot more bolivars to equal every one U.S. dollar...over 100,000 bolivars instead of 250.

Econ: What is the Producer Price Index (...3 Views
And finance Allah shmoop What is the producer's price index
or P P I or pit All right short answer
People A measure of wholesale inflation You know inflation Pump
air into a football It gets bigger Keep eating Boston
cream pies and well you'll get bigger Yep those air
couple of kinds of inflation will in economics Inflation has
to do with prices when prices get bigger like bigger
numbers That's inflation A couple of years ago a movie
ticket cost ten bucks Now it's like twelve fifty That's
inflation Inflation refers to the amount that prices rise over
a given time Right We index it We categorize it
We knew Maris eyes It sort of Inflation is a
key driver of the pp I At least that's what
it's measuring But people measures inflation in a specific part
of the economy See it's relatively easy to see how
much prices are increasing When you're talking about a single
product like that movie ticket right You go to the
store to pick up some adult diapers Eso you Khun
Stream Black mirror without any You know interruptions Been there
done that this week A pack of those diapers cost
you twelve fifty Well last month when you were making
your way through Season five of breaking bad Well a
pack back then Cost twelve thirty five Two months from
now when you're heavy into orange is the new black
Well you head back to the store and a pack
of adult diapers is now a twelve sixty So from
twelve thirty five to twelve fifty two twelve sixty well
prices are going up up up for adult diapers The
A D II or adult diaper inflation index is climbing
fast In just over two months they went up about
two percent or an annualized inflation rate of around twelve
percent That's monstrous people means prices at that rate would
double every six years Well following one products Inflationary tales
should be pretty easy But when you try to discern
inflation rates across an entire economy while things get more
complicated in a dynamic large complex economy like ours well
prices on different products move different directions at different times
Adult diapers might see rising prices but at the same
time prices for ah you know hemorrhoid cream might be
dropping Meanwhile prices for stool softeners are holding steady different
items different inflation trends because different parts of the economy
can have different price trends While there are different economic
stats to track separate segments of the economy the Producer
Price Index is one of these The PP I measures
a particular kind of inflation Specifically it tracks the changes
in prices for wholesale goods Hence the catchy title ng
there with the word produce Sir Price Indexing The first
Pee there Well the P P I is not about
prices consumers pay at the store Rather the PP I
follows prices that companies pay to get the raw materials
they used to make this stuff that shows up in
the aisles at Walmart or it Amazons warehouses The pp
I contrast with the C P I or Consumer Price
Index which measures the retail price is that you know
the regular Joe consumer pays well Here's a list of
some of the stuff that comprises the CP I this
stuff And here's a list of some of the stuff
that comprises the See Threepio Yeah it's different way digressed
Okay You make authentic raccoon skin caps to sell Teo
War of eighteen twelve reenactors you retail the caps for
a hundred bucks each Last month you paid an average
of ten dollars for a raccoon pelt The hundred dollars
retail price represents the consumer price for the cap That's
what the average Joe pays when he buys it in
the store Well Meanwhile the ten dollars for the pelt
represents one of the producer prices you pay You also
have to pay for string and pelt wax and whale
oil to run your authentic eighteen twelve era manufacturing facility
with looms and things But to keep it simple we'll
just look Att pelt prices for now is a stand
in for PP I hear this month the price of
the raccoon pelts goes up to an average of eleven
dollars each That's ten percent higher from where they were
last month So the raccoon pelt component of your personal
PP I was up ten percent from last month to
this month Well the real life P P I is
made of a day divers basket of wholesale goods energy
components like crude oil foodstuffs You know like the stuff
that contains things like weed or rice stuff like that
That's a foodstuff and other components that are included in
it You know from various industries Well they all get
averaged together to create a single measure or a single
index The U S government releases a monthly report outlining
changes in the P P I An increase of point
one percent or point two percent is considered normal Like
things go up to percent a year something like that
Anything above that well could indicate rising inflation pressure Right
Like prices are about to take off But people don't
freak out If one month shows a big move commodities
and wholesale prices tend to fluctuate quite a bit It
only starts to matter of big gains Start to pile
up for a few months in a row So even
though it doesn't measure direct consumer prices the PP I
represents an important economic measure So pay attention to it
Your coonskin cap business experience that ten percent rise in
wholesale prices this month walk the price Then for a
raccoon pelts rose from ten dollars to eleven dollars So
you have a decision to make you Khun Pass along
That cost or expense increased to you to your customer
increasing your retail price from one hundred bucks a unit
to one hundred one To cover that increase expensive a
buck a pelt Or you could just eat the additional
cost and well live with lower profit margins Usually businesses
are reluctant to suddenly pass on increased prices to their
loving customers since commodity markets fluctuate a good deal While
this month's cost increase can disappear next month and then
you just kind of forget about it Also retail markets
are generally competitive The first company to raise prices can
lose out on shelf space or distribution or customer awareness
which all Ri leads to a loss of market share
which would be bad But you went big market share
If you're going to be the king of the queen
of pelts selling if you raise your prices and your
competition doesn't follow suit while customers are going to flock
to the cheaper brand they get a price advantage because
well you panicked and raised prices and you really didn't
need to So if you raise your coonskin price is
one hundred one dollars Cover the rising costs while furry
tops might swoop in with a sail and grab up
a bunch of your customers with lost sales would hurt
more than a slight dip in profit margins That would've
happened Have you raised prices a dollar to cover yourself
So you hold steady and you hope the increased producer
prices or temporary and will you hold your breath with
a big oxygen bottle there However a company can't eat
increased costs forever An upward trend in the PP I
will eventually find its way to the C P I
and people is very important There's a lag between the
FBI and CP I Well the prices for your raccoon
pelts continue to rise It's eleven bucks this month Next
month that rise to eleven twenty five the following eleven
thirty five and six months down the road It's thirteen
dollars Yeah that's a thirteen bucks Well at that point
you can't take the expense increases anymore You have to
increase the price to your customers So you raise the
price for your coonskin caps to one hundred three dollars
making up for the three dollar price increase you've suffered
in buying raccoon pelts over the last several months But
prices for pelts are so high that furry tops in
can't swoop in Now with lower prices they have to
increase prices too because well they've been squeezed with the
same high pel prices you have And similarly the general
PP I figures eventually feed into higher retail price levels
If they don't hire PP I figures eat into corporate
profits which can impact Stock prices are probably would impact
stock prices and eventually the overall economy So yeah that's
the producer price index for pp I a measure of
wholesale inflation complex but still easier to keep track of
than all those Boston cream pies you ate last month
as you continue inflating No just just just just just
