My last post on why expensive oil may just provide liquidity to the global financial system produced some acute reactions on Facebook when someone read it using a Facebook app I use for sharing.
As for using Web 2.0 tools for blogs,
I use Facebook apps called Blog friends and Notes , they give me a continuous feed of friends blogs and similarly promote my blog. I also use the Stumble Upon tool bar in Mozilla Firefox browser , which enables me to submit my post to Stumble upon in less than 10 seconds. The free traffic works.And we have a Decision Stats group on http://www.linkedin.com , which of course provides much better networking than Facebook.
I recently started experimenting with blog tool called www.tumblr.com , which seems a cousin of www.wordpress.com , the software which currently runs this site. If you don’t have the bandwidth (or the money ) but need to put up a site , use WordPress.
And if you want to subscribe to the newsletter , please see the right bar. That is enabled thanks to www.feedburner.com , another company taken over by Google.
Behold the once mighty Bear Sterns
One haughty, now sold for pennies in turn
Its a bear market they say,
Which made Bear Sterns fall away.
The Bulls were rampaging ,
for many a year or two.
Now its the bears turn,
to ravage me and you.
The tiger economies ,
are falling like pussy cats,
As exotic mortages ,
turn fearless men into scared rats.
In between , you will
find an occasional investment guru /ass too.
Promises to know it all, seen it all,
Pontification on TV for you.
Is this a market, we ask,
It seems like a jungle out there,
Leave us in peace, O Wise Ass,
Screw the bulls, and Kill the bear.
Here is an analysis of US Income, thanks to Gapminder , another company acquired by Google Inc http://preview.tinyurl.com/37n6qe
US Income has risen steadily ,despite the Korean War,Vietnam War ,Cold War,Iraq War(s),Oil Shock(s),Japanese Imports, Chinese Imports, Indian Outsourcing.
The simple reason is that a flexible economy is more efficient at using capital than any other economy and the US continues to show the maximum readiness to deal with crisis urgently and with flexibility . Take the sub prime crisis in which the Fed is effectively financing the mortgage debts by its revenues (by sale of Treasuries) to the rest of the World.
Now ,coming back to the title- Why expensive oil is good for you ?
Well ,one thing, Arab terrorists don’t get even a fraction of Oil money. In 50 years of continuous oil revenue, hundreds of billions have been invested by Arab countries in the US financial system , which continues to be the safest and most reliable system in the world. The 9/11 attacks cost only 1 million dollars, and money to terrorists is not an issue because of the much less cost in buying truck bombs, etc..
Well , if Oil rises to 104 Dollars a barrel, where do you think the Arabs will invest those dollars- estimated to be 1-2 trillion of additional global liquidity. Would you prefer Arab countries to have enough money to feed and educate their populations or would you want them to be unstable , with lesser money. Same is the effect of extra money on Russia. Well fed populations are less likely to be frustrated and resort to desperate attacks.
The answer is those dollars are likely to flow back into the US financial system giving Wall street more liquidity than the Fed can give, Arabs and Russians more pride and less frustration, and the banks are less likely to foreclose if they themselves have money in the bank.
Remember banks want to make profits and that can happen if you pay their loans for longer tenures.
Thus expect banks to reduce mortgage payments by increasing tenure, rather than foreclose too eagerly and invite political scrutinies and backlash.
And the Arabs may just save the day for the US financial system.
This is an example of Adam Smith’s invisible hand… Think about that.

How many politicians do you want to see
Cheating on their wives and then apologizing on TV
Making excuses and being sorry for what they do
Caught with pants down and then appealing to you
There was Bill , and he is now trying to get back to White house again
and Larry Craig apologized when he got caught in turn
Apparently paying for it, and getting caught
is worse than toilet knocks ,or having cigars with the intern
Bring back the golden days
When people had affairs discretely
Media minded their ways.
When police didnt leak,
cases like that on TV
This is getting too familiar
or is just me
Getting a man in trouble With his wife and kids
Is not enough , you have to take his job too
Daily assault on senses
Of hapless me and you.
Does the world run out of problems on those days
When politicians get caught with the pants down
Maybe politicians should get some operations done.
Make them impotent before their tenure has begun.
Reading about the latest back and forth and then back again rounds between not that conservative Republicans, conservative Republicans, liberal Democrats, not so liberal Democrats makes you wonder if there is some way of quantifying the daily dose of political news. If we can quantify the level of terror threat in color coding, can we create a blue and red nastiness index for quantifying the political debates in a country.
The Nastiness Index can be used to decribe political equilibrium in a country. eg in USA if the Index shows high blue , and less red it means the Democrats are pummeling the Republicans. If the Index shows low blue and low red, it means all is quiet. If it shows high red, and low blue , it means the opposition is down and the administration is up.Stock markets can use this index to quantify the level of political activity, inactivity and stability of elected governments.
If the nastiness index shows high blue and high red, it means its election time folks.
Presenting a model is different from making a model, as the end audience is non technical and business minded. These are some thumb rules I use for making model presentation templates
1) Model Lift- How good is the model vs current effort.This is best shown by lift curves or KS statistics where you plot % Responders on X Axis and % Population on Y axis. Maximum separation between goods and bads is the KS statistic.
2) Model Robustness- What facts back up statistical validity of model output/equation ? Is there a way to test the model without executing it fully?
3) Model Assumptions- This deals with historical assumptions like which event is the model based on, data assumptions for validation and missing value treatment, capping of outliers.
The best way to convince business audiences is splitting the dataset into three random samples of 60 %,30 % and 10 % for model building, validation and testing again.
Then rerun the model equation on another random sample ,using a different seed in the RANUNI function. The KS should be similar and so should be the stats.
Ultimately models get validated or battered in the marketplace. A 1 % difference in response rates can make or lose hundreds of thousands of dollars especially in mass marketing or credit modeling. Business perspective and buy in is thus essential and so is continuous model performance feedback to avoid deterioration of model, as it will eventually deteriorate over a period of time.
