Fed Unveils Headache-Free QE Math

Fed Unveils Headache Free QE Math
The Federal Reserve Board We-Hate-Math Committee announced the true purpose behind QE.
Do derivatives confuse you? Do you hate bond math? We feel the same way! So we simplified your life with headache free QE math. Compounded rates, equivalent rates, production functions: who needs old math?
Old Bond Math
You want to invest $100,000 for one year. A too-big-to-fail bank offers an interest rate of 10% per annum with quarterly compounding which reflects the bank’s credit risk without taxpayer support for the financial system.
What is the equivalent rate with continuous compounding? What is the value of your investment after one year rounded to the nearest dollar?
The equivalent rate with continuous compounding = 4 x ln(1 + 0.10/4) = 9.877%. The future value factor is e^0.09877 = 1.103812
The future value of your investment is $110,381.
You may be annoyed that we simplified the calculation by rounding to the nearest dollar; we agree, that was oversimplification, but we love simplicity! And that’s chump change compared to how much you are getting ripped off in our new system. So with our new math system, there is no need for rounding! In fact, there is no need to ever calculate equivalent yields or compounded rates again!
QE Bond Math
You want to invest $100,000 for one year. A too-big-to-fail bank quotes the taxpayer subsidized interest rate of zero percent per annum with quarterly compounding. Notice that zero rates make compounding irrelevant!
What is the equivalent rate with continuous compounding? What is the value of your investment after one year?
Your equivalent rate is zero, and e^0 = 1, so your future value factor is 1. What could be easier?
The future value of your investment is $100,000. Unadjusted for inflation, of course!
We did away with inflation calculations, too. It is easy if you do not count food, energy, or healthcare.
Old Math for Economists
You remember the production function:
ƒ(K.L) = ½K^½ x L^½
This represents factory output as a function of capital (K) and labor (L). Let’s solve for the partial derivative of ƒ(K,L) with respect to L.
?ƒ(K,L)/ ?L = ¼K^½ x L^-½
This equation tells us how much production (in the form of factory output) will change when we increase labor and keep capital fixed.
QE Math for Economists
By keeping interest rates at zero, we encourage companies to buy back their own stock and engage in acquisitions instead of using that money for capital spending. The stock market loves it!
We know that with no net increase in capital spending, you can add more labor, but on the margin, it will be less productive, so we’ve eliminated creation of net new full time production jobs!
Also, by keeping interest rates zero, investors in “safe” investments get zero interest, so they are reluctant to spend. There is no need for increased production!
We can eliminate this old math production function entirely!
We keep production, capital, and labor constant and eliminate real growth!
The Genius of the New Math
You may ask when we will raise rates? With real productivity low, why would we raise rates? That’s our story, anyway. Besides, European sovereign debt now trades at negative yields, so in comparison, zero is a windfall for investors! We don’t need to take a step forward when everyone else is willing to take a step back. The new math is safe for the time being.
Bankers and financiers will continue to siphon cash from the productive economy; they will be able to buy more goods and services than savers, taxpayers and voters who could not be bothered to do the math.
Endnote: This is a work of satire, and this is not a press release from the Federal Reserve Bank Board We-Hate-Math Committee.

Yep.. I'm pouring a Gentleman Jack right now ..

Math is for idiots. Smart investors just BTFD!
Oh duh duh duh ...
Economists think that by drawing a bunch of greek (yes GREEK as in GREECE) letters on a page separated by lines and squiggles that the average person will think that the economists are super smart and above reproach. The sad truth is that the economists are right in that people will look at those squiggles and shrug, giving all power to the "rocket scientists" to run the people's lives into the ground.

It is fun for me to think about the practical reality and likely outcomes of negative interest rates.
Hedge accordingly.
Drugs help
Please do a hit of LSD, then read these verses on usury and this article on negative interest rates, then get back to us with your understanding.
Blessed are those nations that are addicted to mind-altering chemicals, for only then shall they truly understand reality?
Blessed are those nations that screw their neighbors before their neighbors screw them, for they shall know love?
Blessed are those nations that pay people to borrow money, for they shall see real economic growth?
Blessed are those nations that love money before anything else, for they will be richly rewarded?
Blessed are those nations that subsidize the killing of their own children, for they shall know joy?
Blessed are those nations that consume more than they produce, for they will know abundance?
Blessed are those nations that bomb other nations into submission, for they shall know peace?
Blessed are those nations that mortgage their citizen's future, for they shall have wealth?
Blessed are those nations that do not uphold their own laws, for they will know justice?
Blessed are those nations that spy on their own people, for they shall know security?
Blessed are those nations that debase their currency, for they shall know prosperity?
Blessed are those nations that punish the truth, for they will also reward the lie?
Blessed are those nations that follow moral relativism, for might will make right?
Blessed are those nations that are obese, for they will know good health?
Satan is known as the father of lies.
HH, Acid is WAY too much for this, even on a mellow Sunday. Holy Shit man - give these kids a break.
Some nice mellow Humboldt whatever and a glass or two of Northern CA wine, and they will be good to go.
Oh good, growth is scary anyways.
Here is the more simple version:
QE = (banksters money)^n
For all n > 1, of course
And n < oo
Damned infinity symbol doesn't work
Just use (10!^(10!))! as a possible upper bound.
Except on Tuesdays
Oh fuck me hb, that was great!
In joke par excellance...
Someone has finally explained 'common core' in terms I can understand!
THNX!
If common core has partial derivatives I will shit a brick. The national curriculum in both the UK and the US keeps getting dumbed down to bolster results, or lower standards so girls can get the same average grades as boys in mathematics and the sciences.
Yes it's true, fiat is becoming worthess, the sheeple just haven't noticed that yet. Look out below when they do figure it out!
I am an engineer, and I approve this math as correct. But what does a partial derivative with respect to one term have to do with anything.
I are an ingineer two.
That equazun don't got partial four pushin on a string neither!
But seriously.. (or not) It's hilarious for the complete stupidity of being a smooth function in the first place and ignoring any "non-linearity" which exist in any system.
Damn! Where the fuck did that come from!?
More Gentleman Jack should help stop that crap.
But it should be modeled using chaos theory.
Chaos Theory? No! Just wait a bit, real chaos is coming. Stack, lock and load. Pitchforks and torches at the ready line.
"This equation is obsolete"........it was never relevant to begin with. Using Roy's identity et al you could bounce around from production function to profit function to cost function - and as cool and convenient as all of that math was, it did little to describe reality. Mathematical masturbation.
Maths is useless, only insiders information is useful
Is that the mathematic equivalent of raping the country? Wadda ya know I Learned something new today. All I need now is a modern army for hire, and to lose my morality and I'll be ready for my new career in oligarchy.
Pretty simple Calculus, really. It tells me that...
If you keep the Kapital fixed and increase the Labor linearly, the output will increase non-linearly (1/sqrt(L)).
Bullish!
Oh yes we have full on substantiated Plos One study that the fear of math gives people real physical pain and I used to refer to this study with a little touch of satire, but darn it's really true. I have recently had a few quants refer to it as well:) It doesn't get any better than this.

So this is why are are a nation that is lead around by media distractions, i.e. the Hillary email server:) Ok so watch video #1 at the Killer Algorithms page or you can find it as video #1 in the footer of any of my blog posts "Context is Everything" a video from mathematician Charlie Siefe done a couple years ago at Google's NY headquarters, telling their employees how they get duped with math. It's very well done and even entertaining. You will learn that there is no math formula for the perfect butt and he takes apart some of the other crap you hear in the news too. Pay attention to the end with the Russian nuclear testing questions as right now with Putin this has some interest as the US used bad math back in the Reagan era and it's never been solved. The US geologists begged Reagan not to go there but he did.

I wrote another opinion post on this topic saying it's time to tear apart some of the proprietary code out there and check it for accuracy. I used to write software and what a deal when you can compile your code to where nobody ever gets to see it and just rape the heck out of everyone's trust and get everyone to buy in to fake numbers...such a deal.
http://ducknetweb.blogspot.com/2015/03/its-time-to-look-at-some-of-proprietary.html
When it comes to markets and Quant formulas, proprietary code is always up for good conversation is it not? It's the back bone of front running I could venture to say.
According to the Fed.. Math can be anything you want it to be as long as the result is
It is pretty obvious there are a lot of engineer-type geeks here on ZH. Love you all. I have an MBA, which means I majored in young women, party,extra-curricular actiivities, and business stuff, plus my minors in geology and economics (more or less in that order, except I really enjoyed economics - but not as much asd young women), but I never made it through calculus, though I did well in stat.
Great bunch of posts. Thanks.
