The photographs of Wall Street were taken at Bryce Canyon National Park on September 20, 2011 inUtah.
Bair says, 'My Nightscapes are exposures of the night sky with a landscape feature. All are evening time exposures.'
'Many are taken with special equipment in order expose the night stars without blurring. Some land features are enhanced with light painting.'
I have been giving lectures and workshops, internationally, on night photography for two decades.'

Trickle Down Effects
Saturday, February 25, 2012
time is your friend, and enemy (be a tortoise)
Remember the old story of the tortoise and the hair? Be a tortoise. Constant and steady.
If you don't, odds are that you are a sucker and will always be a debtor, not a creditor.
Does your interest compound on your initial blance? Or does it compound on the new balance?
Know the Difference between Simple and Compound Interest
Type of Interest | Principal Plus Interest Earned |
Simple | 46,000.00 |
Compounded Yearly | 299,599.22 |
Compounded Quarterly | 347,109.87 |

Take a minute to review the graph below by Franco Modigliani , 1985 nobel prize winner
The shaded area to the left is your average 20 year old in school with mounds of debt. (or mounds of debt because of a mortgage, etc)
Think of the thick black line as consumption.
Think of the thin black line as income.
You can only do 2 things.
- Increase income
- Decrease consumption
Practical Principals for Provident Living
1-Increase Income: save between 15-20% of income now
- set up automatic withdrawal from bank account - if you have to make a conscious decision to save every month you'll never do it
- save all of tax returns/unexpected earnings
- If you have debt, pay it off. That is a form of saving. When you pay off your debt do not increase your consumption, just keep making the payments, but this time not toward the debt, toward savings!
2-Push down consumption
- find a few small habits and eliminate them
- don't buy on impulse
- budget
- Don't buy lock-ins ie gym memberships or cable tv
- Let's put this in perspective: If I contribute $1 per day ($360 per year) for 50 years, at 5% Return, I’ll have more than$79,000! (check out this post for more info)
3-HOW to save - not in one basket, and diversify
Get into indexed funds for the long run. Buy now and let it sit for 40 years.
Many studies have been done on this, the best way to diversify in the long run is to have 4 indexed funds:
- indexed funds get an 8% ROI in the long run, don't bother hiring a broker
- be careful of indexed funds transaction costs ($10 a purchase, etc.) and buy accordingly
- indexed funds have .015% operating costs, therefore 7.85% return on average (real rate of return)
- avoid mutual funds!!
- Right now US Treasury bills rate of return is at about 2%. Don't believe anybody that tells you that there is a certain 20% rate of return
- It is a game of the tortoise and the hair. If you are a tortoise you'll be wealthy when you're old.
- Buy now and hold. You will get 8% real rate of return.

China vs. USA
Phase I - Artificial devaluation of Yuan, Maintaining Trade Imbalance
1-China exports more goods to the USA than the USA exports to China.
2-China gets revenue in USD and wants to convert it to Yuan
3-USA gets revenue in Yuan and wants to convert it to USD
4-More demand for Yuan than for USD because China has more revenue in USD than does usa in Yuan
5-This makes the price of the dollar relative to the Yuan fall. Yuan appreciates, Dollar depreciates in value.
6-****This makes the Chinese upset because when the dollar is weaker they know that the USA will buy less goods from them, therefore China does not want the USD to get weaker nor do they want theirs to get stronger. They want things to stay how they are. They want to have a trade surplus. China wants the US to have a trade deficit, so that the US will keep buying China's goods. China wants their producers to be able to produce things for less. China does not want to lose their price advantage.
7-What does China do to make it so that they can stay cozy in their current position? They artificially devalue their currency, (thereby increasing the value of the dollar). They print off Yuan and trade them for dollars. As China increases the value of the dollar (by trading dollars for printed Yuan) and decreases the value of the Yuan (by printing more Yuan), this makes it so China maintains its trade surplus, and the USA maintains its trade deficit. China avoids the equilibrium.
Phase II - T-BONDS
8-Q:So what does China do with all of these dollars that they bought with Yuan that they printed to artificially devalue their currency? A:They buy treasury bonds from the US Government. (also reffered to as "t-bills" "t-notes" "t-bonds"; t-bills = less than a year, t-bonds=more than a year)
9-When China buys t-bonds with their dollars it creates more demand for t-bonds. What does more demand for t-bonds do ? drive up the price of t-bonds. Is this a good thing for the US gov't/USA? yes! This means that the US Gov't&/USA has to pay less interest to borrow money because so many people are now willing to lend it to them. Thus, debt in general in the USA is cheaper.

How much to produce?
Butterfly Effect
Friday, January 27, 2012
Optimal Amount of Crime - Marginal Benefit / Marginal Cost changes with innovation
A: Yes.
How? If the marginal benefits for policing one more unit of crime are less than the marginal costs for policing one more unit of crime, then we don't enforce the law because it is too costly
This principal is illustrated in the first graph below. The benefit for policing Murderers and stoping homicides is far greater than the cost of doing so. However, the cost of policing J-walkers is far too high compared with the benefit. It is important to note that the costs and the benefits are measured in dollars for conversation's sake.
So, What happens if a huge technological innovation all of the sudden makes it much less costly to police (ceteris paribus)? The marginal benefits for policing crime stay constant, however the cost of policing crime has been greatly reduced. This innovation would allow us to catch more J-walkers and more petty crime in the like, at a lesser marginal cost. (illustrated in the graph below)

Supply and Demand
X axis = Quantity Demanded
Y axis = Price in $
At PBAR (top, blue) Qd and Qs have an excess of supply.
At P2 (orange) Qd is less and Qs is more. The excess of supply decreased as the price moved toward the equilibrium(intersecting points)
P* is the equilibrium price at which supply and demand will always flow to. This concept is similar to a pendulum that always swings toward the equilibrium spot.
my good friend Khan helps us out on this topic with his microeconomics video:

Arrow Paradox
Horse Power | Color | Sex Appeal | |
---|---|---|---|
Chevy | PREFERRED | ||
Ford | PREFERRED | ||
BMW | PREFERRED |
1st Preference | 2nd Preference | 3rd Preference | |
---|---|---|---|
HORSE POWER | Chevy | Ford | BMW |
COLOR | Ford | BMW | Chevy |
SEX APPEAL | BMW | Chevy | Ford |
This idea is very simple given the data above.
the data it indicate:
Chevy is preferred to Ford 2:1
Ford is preferred to BMW 2:1
BMW is preferred to Chevy 2:1
-or-
BMW is preferred to Chevy which is preferred to Ford which is preferred to BMW which is preferred to Chevy which is preferred to Ford.. etc...
Unless there is a different weight for each preference, you can not make a choice between Ford, BMW, and Chevy.
This argument is used to say that there is no democracy. All democracy has to do with is the order in which candidate A vs. B vs. C approach each other (or the order in which you present Chevy vs. Ford, then Chevy vs BMW).
"it has been said that you can rig an election by presenting alternatives in a specific order."
Using the example above:
If I present Ford vs. BMW as your first two alternatives, then you pick Ford because it is preferred 2:1 to BMW.
If I then present Ford vs. Chevy it is preferred to ford 2:1, therefore you pick Chevy. but if I had presented BMW the first time, you would have picked BMW.

Property Rights
Metcalfe's Law

Social Innovations
The Whales are going extinct! Why? Because they are comunal property. Nobody owns them. Since nobody owns them every whaler on the planet plunders and loads his boat with all the whales he can fit with each venture. Why? Because he has no incentive to save the whales. He knows that if he doesn't kill the whale the next whaler will do the same.Why is this only happening to Whales and not Cattle ? The Cattle are owned by farmers. It is in the Farmer's best interest to keep his population at a sustainable rate and practice sustainable practices. The farmer won't plunder and pillage because he knows that it will only be to his detriment.
The key point here is: Ownership & Enforcement of Ownership must prevail, and when it does, The cattle rancher will align himself along his PPF (maximum output).
Today's simile: A social innovation is like a Policeman.
Double Coincident Want Problem
Another cool thing that we talked about was the fact that In a barter economy, nobody will specialize, because if I am to trade an M.D. his medical services for my web design, It is just so hard to figure out what amount of his medical services I need to give what amount of Web design for that ? The solution is money. wether it is Wheat or a stick or a piece of paper, money is the solution.
Money $$$$ what is $$$$$$$ ? it is a common good accepted by everyone.
If I accept money I only accept it because I know that somebody else will accept it from me! It has nothing to do with me liking it.
Opportunistic Behavior
Oil Refinery and Oil Pipeline analogy. The pipeline is owned by company A and the Refinery by company B. If company A were to commit to build the pipeline company B would then exploit them to the max.
Q:How do we overcome this issue?
A:vertical integration. aka joint ownership. When two different companies combine forces and invest together so that A can't screw B and B can't screw A
A2:Contract enforcement. (Gov't)
A3:Reputation of Company A or B at risk.
That's all folkz

Furthermore- pills are so heavily regulated that no FDA bureaucrat wants their neck on the guillotine if they were to approve a "bad" pill. Therefore they take 0 risk. Even if the risk would benefit the populous as a whole. They have incentives to not allow new drugs to enter the market than to allow them in. If they do not allow the life-saving pill in the market, nobody but a few scientists will know about it! If they allow the bad pill in the market their reputation and latter-climbing potential just went to pot. I'd act the same way, that is why the social structure needs to be reformed in regards to FDA regulation of pharmaceuticals.

Death makes me reflect on something that I had heard weeks ago- "Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. " (Steve Jobs, 2008). There is a statement in the book of Psalms that reads: "So teach us to number our days, that we may bet us a heart of wisdom." There is much truth in this statement. my days are numbered. When I realize that my days are numbered, I then become a living creature. I soar above the vein, the dogma, the minute. I have wisdom. Wisdom that says that I will die so I must live every second to the fullest! "…the nearness of death intensif[ies] every aspect of life."
Knowing that I will die, knowing that my days are numbered, does not mean that I anticipate diminishment and sorrow; rather it makes me at peace with death. Being at peace with death slaughters the demon on my back and frees me. I know that I must live and live and live and live and live my life without bounds. At any minute the reaper will slit my throat and I am dirt! How I must never forget this!
My dearest reader, I pray that you and I may be free from the burden that death is. I pray that we may open our eyes and realize that we are and that our days are numbered!
