Crazy Schizo Quants

OK, so back in 2012 the Right Wingnuts were blaming Obambi for hiking gasoline prices (and, by necessity, petro price). The lobbyer doesn't have a link to the advert, anymore, so here's the quote of note:
Since Obama became president, gas prices have nearly doubled. Tell Obama we can't afford his failing energy policies.

Today, Mr. Market, led by the same Right Wingnuts is going out of its mind over falling gasoline and petro prices: here (and, of course, nearly every news source).
U.S. benchmark crude scythed below $58 a barrel for the first time since May 2009 for a weekly loss of nearly 12 percent in the midst of a tumble whose severity and magnitude matched what happened during the 2008 financial crisis.

Makes one wonder who the USofA economy is run for? All of us?? Or hedge funds?

Those Crazy Quants

Regular reader, by now, is aware that I take the view that quantitative analysis is for both fun and profit, but that it should be attempted somewhat gingerly when the venue is human behavior. We get to make the rules up as we go along, unlike the other animals, minerals, and vegetables which live by God's (or Nature's, depending on your -ism) rules. The rules don't change. We ain't Brownian motion, fur shur.

Well, I just found this post on r-bloggers.
The eBook reprints several unpublished articles and reports from the Econophysics Group at ETH Zurich.

"Econophysics"???!!! And all this time, I'd viewed the Europeans as, generally, more astute. Guess not.

Widget Wonderland

Three semi-related posts went past my eyeballs today. The thread which hangs them together is the value of value. How do we figure it?

First, Blankenhorn takes on Amazon, among my favorite fubar companies. As is often the case, the comment stream is as significant as the post. The poster child for the "we lose money on each sale, but make up for it in volume" approach. Either Amazon attains monopoly, i.e. pricing, power over retailing or it goes belly up.

Second, one Peter Greulich (not familiar) takes on IBM. Here the issue is both the danger of goodwill and the structure of companies. How to value IP, services from IP, and goodwill (e.g. the sale of WhatsApp)? IBM has been shedding real capital and real production for many years. It wants to see the ROI of software driven services. The WhatsApp home run as paradigm for Big Companies, if you will. So do many corporations. Good luck.

Third, Rob Hyndman takes on Data Science. What is it? Who does it? Is it just stats with a new name? Is it just OR, with a new name? Is it more, in some sense, than just stats (Janert says so)? Likely.

Taken together, some musings on the value of value. Micros and quants invariably practice reductio ad absurdum (in the second sense, and on themselves) by looking only at the financials and ignoring the real world aspects. How else would they have blessed liar loans? If quants and micros took the "science" part of data science seriously, may haps we wouldn't go through Great Recessions? One of the comments on the Hyndman post is on that point.

If science viewed thought as property, we'd still be cavemen.

Prometheus Unbound [update]

The mainstream pundits, and the blogosphere too, continue to be perplexed by the refusal of open market interest rates to rise as they had hoped/wished/needed. So, it falls to moi to yet again 'splain some more.

The notion of moolah as commodity rests on the base assumption of trade in real goods: that supply and demand are functionally infinite, and that the "curves" result from individuals' (and remember, corps are people too) levels of psychic satisfaction. To put it yet another way: real demand requires only that "I" want another widget and have the moolah to pay "more" for that widget. The only limit is my satiation with said widget. On the other side, supply, Widget Corp. is willing to make widgets until Hell freezes over if enough folks want them. Availability of production inputs are assumed to be infinite in the sense that a source of supply always exists, at some price.

Now, when it comes to investment, the situation gets a bit gnarly. The MBA types, and most quants, don't distinguish between fiduciary capital and real capital. Most, likely, don't even acknowledge that the latter even matters. But, of course, it does and explains what's going on now. Financial engineering isn't real engineering; not by a long shot.

If we view moolah as an investment commodity, then the gnarl sets in. On the supply side we have retained earnings by business and non-consumption by the rest. On the demand side we have business. What's the motivation by business to take fiduciary capital (moolah, to you and me) and turn it into physical capital? One thing only (in a rational world, of course): that the plant and equipment so made will yield more profit than by not doing so. Nothing else. Financial engineering, so beloved by Wall Street and The City, doesn't count.

Note, however, the difference in the demand function betwixt consumer demand and capital demand: the consumer just wants a better hard on, but the CxO demands that the capital produce returns **not otherwise attainable**. The CxO, if s/he's rational, isn't maximizing some satisfaction function, but some very specific engineering breakthrough. In order to get that return the CxO has to know, or have a high probability, that the new plant and equipment are better than what s/he's got now.

Said plant and equipment may be something entirely new, such as a Swiss screw machine around 1870, or it could be off-the-shelf items not yet adopted by a business. Either way, unless such plant and equipment actually exist, there is no demand for the fiduciary capital. It will just sit around as retained earnings or used to buy back shares or buy bling for the CxO class. Since the MBA and quant class remain stuck in a 19th century mindset (Right Wingnuts all), they can't see that the arc of technology and resource availability has turned, at best, flat. If one considers the widgets we use today, how many implement a semantic that didn't exist before say, WWII? I'll bet a nickel that the number is 0. Capital has spent the last few decades in ever decreasing incrementalism. Ponder that for a moment. Near zero interest has not a thing to do with Big Gummints, but an utter void in the heads of the CxO class to find new, and useful, ways to turn moolah into machines.

This is the base reason so much fiduciary capital has been thrown at non-productive uses such as residential real estate. The Masters of the World are intellectually adrift. And we, as a species, know just about all there is to know about physical reality. Hell, we've found the God Particle. Once you've reached the edge of the World, there's no frontier to explore.

[update]
Sometimes ya just shouldn'ta oughta got out of bed. Left the punchline in the briar patch. So, here it is.

Widget Corp. can go buy more land, labour, and physical capital if it has the moolah. What it can't buy is any new Law of Nature (or God, depending on your -ism) or the brains to find it. Those two either exist, or they don't. These days, the chances that there remain any of the former get nearer and nearer to 0 and thus the chances to buy the latter (I wonder, would paying Newton or Einstein more moolah made any difference?) do too.

A Rock and a Hard Place

From the first time I recall seeing him, I've been convinced of Chris Rock's cerebral approach to comedy. Yes, he is foul mouthed, but the fundamental ideas are sound. He is of course, a high school drop out. Stay in school kids.

So, it comes as no surprise that he and I have/had a similar take on the 2008 election: force the Right Wingnuts to wear the albatross. I was pretty convinced that I should vote for McCain, since there would be no way for the Right Wingnuts to avoid the albatross with the McNugget in the White House and Palin pandering to the guns and God folks. It would be a painful time, but the Right Wingnuts would be toast. Likely for more than a generation.

Didn't happen.

What happened next was predicted: the Right Wingnuts out maneuvered the Obambi into a Trickle Down Recovery, thus getting nearly all the moolah, and the 99% a crumb here and there. Obambi, and the DNC, did the dirty work of the Right Wingnuts, who get to point at Obambi and say, "where's the jobs??"

In the end, we really elected McCain and Palin.

60 Seconds

That appears to be how much time and effort went into last night's "60 Minutes" piece on consumer credit card and ATM and such hacking. If you accepted the statements made, then you believe:
1) retailers and banks are doing everything humanly possible
2) Eastern European hackers are the Smartest Computer Folks in the World
3) breaches can't be stopped
4) Corps. should buy the services of that "security expert"

Here's what we actually know (and the "60 Minutes" reporter[s] would have if they did any reporting):
1) the POS breaches are due to antique versions of Windoze that Corps don't want to spend money to upgrade
2) Corps. routinely don't isolate valuable and vulnerable customer nets from the rest
3) hackers are using time honored methods to breach old versions of Windoze
4) banks are replacing OS/2 run ATMs, which are nearly bulletproof, with Windoze rather than secure certified *nix
I want to be clear with my point of view here. I think that migrating from OS/2 to Windows is the most stupid thing that can be done to an ATM Machine.

So, as with the coders who refuse to upgrade their skills to Organic Normal Form™ schemas, Corps. continue to run vulnerable systems for customer data just because it's seen as too expensive in time and money "to do the right thing". [Aside: if banks ran ATM networks as described by Allen Holub in "The Bank of Allen" series, none of these problems would occur, of course.] IOW, once again, the problem isn't tech it's politics. The restitution, if any, is a slap on the wrist. Just a cost of doing business. The restitution and fines for allowing breaches can be written off, so the taxpayer picks up most of the cost. The upgrades can still be put off. The CxO types still get their fat bonuses for saving on IT spend by not taking security seriously.

Play to the Front Row

The pundit class has been wondering, in print, how it can be that we have increasing income/wealth inequality, but, if one believes the data, a recovery from The Great Recession and general growth.

The answer, in a nutshell, is Apple. Apple has made a living by ignoring the bottom 80% (or thereabouts) and selling a limited set of models to the top 20% (or thereabouts). A small list of models means what Henry Ford (is said to have) said, "you can have it in any color you want, so long as it is black". Smaller global BoM, smaller unit cost, higher gross margin. You just have to convince your market that they only need that one model. Mo money. As other microeconomists and quants see the light; likely have for some time, what can we expect?

As these endeavors have pointedly asserted, when it comes to data, analysis and decisions based on data is a worthy exercise only when the venue under analysis obeys God's (or Nature's, depending on the -ism you subscribe to) laws. Read the news every day, and you'll find a case where the clever (but not clever enough to avoid getting nabbed, of course) have bent or changed the rules to their advantage. Data on human endeavors is not reliable when used to predict the future. The future's rules won't be today's or history's. When the players are making up the rules as they go along, relying on recent data is foolish. Data driven decision making only works when the decision makers are forced to obey a rule set out of their control. Lower animals and glaciers come to mind.

When the recommendations of data and incentive conflict, follow the incentive. The clever will, like mouses, squeeze through the tiniest crack in the wall. Build a new wall, and they'll find the new cracks. Time series won't tell you where those cracks are.

So, what does Apple have to teach us? First, that by concentrating on the High End, its market in units is limited; as concentration continues apace, the number of individuals near the top X% diminishes as the X%-ers accrue more moolah. Apple counters that fact by limiting models of any device, and thus minimizing corporate BoM. The counter is to increase the number of distinct devices. Whether the iPad (or the don't-call-it-an-iWatch) can survive is an unanswered question. Reporting today reveals geographic/economic differences in mix between iPhone 6 and 6+. Why might this be? The logical conclusion is that lower wealth populations will have more buyers willing to compromise both ends of the size factor by having just one device. The phablet only holder, while the higher wealth populations will have a more reasonable device for each end of the size factor. Should this be a surprise? Not.

What of the macro effect then? It depends. That Burberry marketing gal had an easier time of it peddling coats than she will compute devices. In general, the top X% will have more moolah to spend on bling, but they won't necessarily spend more on bling from any one XYZ, Inc. widgets. Said widgets, unlike fancy coats, may have no value beyond having one. What we should expect then (looking at the incentive, not the old data), is to find more XYZ, Incs. making different sorts of bling for the X%-ers. Samsung was reported in the last couple of days to be reducing its model count drastically. Lowering the corporate BoM to make more moolah. So, what's the next big thing in X%-er bling? I wish I knew.

But, not all is wonderful in X% land. Consider participant sports. Turns out Tiger Woods is thought by some to be key to the golf widget makers' survival. Golf can be an expensive pastime, right up there with skiing. Poor person envy? May be yes, may be no; but it doesn't matter to the analysis. I've never had any interest in either, which I can duly afford if I wanted to. And therein lies the problem with growing the moolah flow to providers of the various bits and pieces associated with them: how to engage the small population that is the X%-ers, because only they can afford the vig. What Americans play tennis anymore?

Professional team sport provides some insight into how it can be done. Players in these stadium sports get ever more tens of millions of dollars per annum to behave like teenagers. How can this happen? Again, look to the incentive. Partly, TV dumps billions of dollars into the pot. But consider the stadiums. Research (I've not got cites to hand, but they weren't hard to find when last I went looking) has shown that most are partly or fully paid for by taxpayers, both directly and indirectly. Most are in large metropolitan areas, where the number of seats is a small fraction of the market population. Since, let's say, the stadium on average needs 50,000 behinds to fill it up, then the team need only convince the increasingly wealthy 50,000 to attend out of a few million in total population. They have no need to attract the lunch bucket crowd. IOW, the Apple crowd has another way to spend disposable income. For the privilege of being special, they can afford to pay yet more. The Washington football team attacked in 2009 when The Great Recession hit. All was not well in Mercedes land (for the record, the real money in the DC area isn't made by civil servants). What's odd about such suits (the piece reports that Washington is not alone in suing) is that, according to legend, season tickets for Washington football (and many others) has a long waiting list. Hard to see where the loss is? Kind of like foreclosing on a house that's still brand spanking new. It should be no surprise that the various leagues expansions into ever smaller markets (hockey in Florida, Arizona, and North Carolina???) have led to failures, and near so. They have to have some minimum population to have the necessary 50,000 X%-ers. Some leagues (3 of 4, not NBA, near as I can find) counter with "revenue sharing" wherein the rich big city owners give to the small hick town owners, aka rich white guys' Socialism.

In general, the incentive for an economy's production under rising concentration of income/wealth is to shift to more varieties of lower volume bling. No one needs two smartphones, drug dealers and con artists possibly excepted, so some other forms of bling must be created to sop up the excess moolah. This happened before in the USofA. The most well known was called The Gilded Age, a coinage and book title from Mark Twain, which, by way of setting context, he wrote before both "Tom Sawyer" and "Huckleberry Finn".

So, the question for macros, micros, and quants: can such an economy thrive? And, of course it can. Except for the period post-WWII to the 1973 oil embargo, that's been the history of the USofA. It was only that rather short period of unspoken Socialism that is the unusual condition. The downside, depending on which side of the X% you sit, is the necessity of an increasingly motivated police state to keep the non-X% from revolting. If you read 19th century American history, it was awash in minor and major insurrections. The fact that there was ever more land to move to and pillage helped keep the lid on, until it didn't. The Civil War is the one remembered, but there were more clearly economic ones across the century. Here is another list, but both don't include Bloody Kansas, more properly the First Civil War. So, of course we can have an economy based on the top X%, but as X gets smaller, the police state must get more motivated. And to think, all those ex-Middle East armored personnel carriers and such have found their way to civilian police under a black president. The X% can't say, "if you don't like it here, move to the frontier and see if it's any better." There is no more frontier. Have a nice day.
