Laplace’s Hammer: The End of Economics

Laplace’s Hammer: The End of Economics

Courtesy of Tim at The Psy-Fi Blog 

Clever Man, Stupid Idea

Simon-Pierre LaplaceSimon-Pierre Laplace was a Very Clever Man who did many Very Clever Things. Unfortunately, like many clever men, having got hold of a Brilliant Idea he was rather inclined to go off and use it on everything in sight, which led to a number of Very Odd Conclusions. In fact as far as science goes, he may well have been the original man with a hammer; taking aim at every problem as though it was a nail.

As is the way of these things economists got hold of Laplace’s ideas, converted them to their own and started developing delicate and intricate webs of theories and practices. Unfortunately, over the succeeding three hundred years they’ve failed to keep up with advances in physics and biology, rather leaving economists as the only believers in an approach that suggests we have no free will, a position from which they’re having to be dug out and defused, one unexploded theorist at a time.

Newton’s Error

When Isaac Newton published his theory of gravity he knew it contained a serious flaw; his equations didn’t exactly match what was observed. He reckoned, correctly, that the differences between his theory and the observations were down to the gravitational effect on the planets of other planets – so called perturbations, which he didn’t know how to mathematically model. He said:

“But to consider simultaneously all these causes of motion and to define these motions by exact laws admitting of easy calculation exceeds, if I am not mistaken, the force of any human mind.”

And, of course, he was mistaken. The force of Laplace’s mind successfully solved the problem. Having achieved this, though, Laplace went a stage further. Because he could exactly calculate the position of any planet he could compare this with the results of observations from astronomers. What he discovered changed human history.

Observer Bias

It turned out that observers made errors, but they made them in a particular way – their observations fell about the actual position of the planet in a very distinctive pattern. This pattern, of course, was the ultra-familiar Bell curve or normal distribution. Laplace realised that human error was statistically quantifiable and, therefore, could be effectively eliminated from the data. This…

The Next Round of the Great Crisis is at Our Doorstep

Courtesy of ZeroHedge. View original post here.

Submitted by Phoenix Capital Research.

The next round of the financial crisis is at our doorstep.

Central Bankers bet the financial system that their academic theories would work, despite the countless real-world examples showing that printing money does not generate growth.

After all… we know that…

1)   Stocks are expensive by just about every conceivable metric.

2)   Global GDP growth is overstated dramatically with China at most growing 3.5% per year, the US in recession, and Europe in a full-scale DE-pression.

3)   QE is completely useless at generating growth with Japan in a triple dip recession after launching a QE program equal to 25% of its GDP and the US in...

The "War On Cash" Migrates To Switzerland (Acting-Man)

Banks Increasingly Refuse Cash Withdrawals – Switzerland Joins the Fun

The war on cash is proliferating globally. It appears that the private members of the world’s banking cartels are increasingly joining the fun, even if it means trampling on the rights of their customers.

Yesterday we came across an article at Zerohedge, in which Dr. Salerno of the Mises Institute notes that JP Morgan Chase has apparently joined the “war on cash”, by “restricting the use of cash in selected markets, restricting borrowers from making cash payments on credit cards, mortgages, equity lines and auto loans, as well as prohibiting storage of cash in safe deposit boxes&rdqu...

World Markets Weekend Update: The Rally Resumes

Courtesy of Doug Short.

Seven of the eight indexes on our world watch list traded higher this week, with China's Shanghai Composite as the top performer, up 2.48%. India's SENSEX was the outlier to the south, with a -3.53% contraction. In fact, the average of the seven gainers was an impressive 1.52%. But the SENSEX pulls the overall average down to 0.89%.

The Shanghai Composite looks to be in bubble mode, up 92% from its interim trough in late October.

Here is an overlay of the eight for a sense of their comparative performance so far in 2015.

Here is a table of the 2015 data performance, sorted from high to low, along with the interim highs for the eight indexes. All eight indexes are in the green, with the top five gains ranging 14.72% to 35.83%. Not bad for a mid-April checkpoint.

King Dollar slipping below support, say Joe Friday

King Dollar has been on a role since last summer, up over 20% in less than a year. When looking back on the US$, the rally has been rare and nearly historic. Majority of the rally took place inside the steep rising channel above. Over the past month the US$ might have put in a double top. Over the past few days, the US$ has slipped a little below rising support at red arrow above.

Why Bitcoin's male domination will be its downfall

Here's an interesting argument by Felix Salmon, although I think he is taking two correct observations and mistakenly attributing a cause-and-effect relationship to them: Bitcoin is going nowhere because women are not involved.

More likely, in my opinion, women are not involved in bitcoin because bitcoin is going nowhere (and they know it). Or maybe, simply, bitcoin is going nowhere and women are not involved. 

Why Bitcoin's male domination will be its downfall

Nathaniel Popper’s new book, Digital Gold, is as close as you can get to being the definitive account of the history of Bitcoin. As its subtitle proclaims, the book tells the story of the “misfits” (the first generation of hacker-l...

Sector Detector: Earnings and GDP temporarily take investor spotlight off the Fed

Reminder: Sabrient is available to chat with Members, comments are found below each post.

Courtesy of Sabrient Systems and Gradient Analytics

As we get into the heart of earnings season and anticipate the GDP report for Q1, the investor spotlight has been taken off the Federal Reserve and timing of its first interest rate hike, at least temporarily. Even though Q1 economic growth will undoubtedly look weak, the future remains bright for the U.S economy – even though many multinationals will struggle with top-line growth due to the strong dollar – and any near-term selloff resulting from weak economic or earnings news should be bought yet again in expectation of better results for the balance of the year. High sector correlations remain a concern, reflectin...

Kimble Charts: South Korea's EWY

By Ilene 

Chris Kimble likes the iShares MSCI South Korea Capped (EWY), but only if it breaks out of a pennant pattern. This South Korean equities ETF has underperformed the S&P 500 by 60% since 2011.

You're probably familiar with its largest holding, Samsung Electronics Co Ltd, and at least several other represented companies such as Hyundai Motor Co and Kia Motors Corp.

S&P 500 Leverage and Hedges Options - Part 2

Courtesy of Jean-Luc Saillard.

In my last post (Part 1 of this article), I looked at alternative ETFs that could be used as hedges against the corrections that we have seen during that long 2 year bull run. Looking at the results, it seems that for short (less than a month) corrections, a VIX ETF like VXX could actually be a viable candidate to hedge or speculate on the way down. Another alternative ETF was TMF, a long Treasuries ETF which banks on the fact that when markets go down, money tends to pack into treasuries viewed as safe instruments. In some cases, TMF even outperformed the usual hedging instruments like leveraged ETFs. There could of course be other factors at play since some of 2014 corrections were related to geopolitical events which are certain...

2015 - Biotech Fever

Reminder: Pharmboy is available to chat with Members, comments are found below each post.

PSW Members - well, what a year for biotechs!   The Biotech Index (IBB) is up a whopping 40%, beating the S&P hands down!  The healthcare sector has had a number of high flying IPOs, and beat the Tech Sector in total nubmer of IPOs in the past 12 months.  What could go wrong?

Phil has given his Secret Santa Inflation Hedges for 2015, and since I have been trying to keep my head above water between work, PSW, and baseball with my boys...it is time that something is put together for PSW on biotechs in 2015.

Cancer and fibrosis remain two of the hottest areas for VC backed biotechs to invest their monies.  A number of companies have gone IPO which have drugs/technologies that fight cancer, includin...

Help One Of Our Own PSW Members

"Hello PSW Members –

This is a non-trading topic, but I wanted to post it during trading hours so as many eyes can see it as possible.  Feel free to contact me directly at jennifersurovy@yahoo.com with any questions.

Last fall there was some discussion on the PSW board regarding setting up a YouCaring donation page for a PSW member, Shadowfax. Since then, we have been looking into ways to help get him additional medical services and to pay down his medical debts.  After following those leads, we are ready to move ahead with the YouCaring site. (Link is posted below.)  Any help you can give will be greatly appreciated; not only to help aid in his medical bill debt, but to also show what a great community this group is.

Thank you for you time!
