Do traditional Economists have it right or do Behavioral Economists have it right? Should all people be considered to be acting to maximize their own utility or are we satisficing (or do we often even shoot ourselves in the foot)? This blog explores concepts in consumer-side economics including theory, experimentation, and policy in an attempt to answer the question, "Can economics save the world?"

Wealth-Debt-Income-Invesment-Wealth
http://www.forbes.com/sites/investopedia/2014/01/28/a-study-on-the-wealth-effect-and-the-economy/2/#154cbef468a4
But what about using your home to arbitrage investments? Miller-Modigliani proves that, in efficient markets, debt is simply negative cash and if an opportunity exists to create additional wealth or income by investing in another asset then you should jump at it. Many people leveraged their primary residences and bought second (and third) homes, investment real estate, and other assets like stocks and bonds during this period of time to increase wealth. These are seemingly rational responses to incentives. When it was discovered that markets not directly related to housing or stocks were inefficient (the CDO crash), many assets lost value due to the waterfall effects. More research is needed here to uncover the vectors of inefficiency before drawing conclusions about what to do with wealth. Converting wealth to income is certainly not always a bad thing, even when the conversion is for consumption, if future income is rationally assessed to be greater. But, I would argue, the circumstances of the conversion and the ultimate use of the funds can have a chicken-and-egg effect on asset pricing.

Antidisestablishmentarianism
It seems to me that many voters right now are trying to run away from reality. They want people not like them to cease to exist, and they want money to cease to exist. In the case of extreme “conservatives”, they want to enjoy a privileged lifestyle without all those “others” not like them mucking things up. If they currently do not have what they consider to be a privileged lifestyle, they will latch on to somebody who they think will bestow it upon them when their leader successfully rids the country of those others. In the case of extreme “liberals”, they want equality, transparency, and a “flat playing-field” for all. Either way, voters appear to want the fundamental forces of competition to disappear and they want their leader to make money obsolete as a means of distributing resources. They want to blow-up our system and rebuild it according to the vision that they believe their leader has. In other words, ostensibly "anti-establishment" voters, paradoxically, appear to want a dictator right now. Forget all that messy “free and democratic” stuff, let’s create utopia right now. “My utopia.”
As of the past several months, I feel like I have been dropped into an alternative universe. It seemed impossible that two people so utterly at odds with one another in almost every way could possibly have put at risk the most well-established and formerly stable political system in the world. I find myself actively avoiding the news. In this piece, I have posited that the last economic crash awakened a basic fear in our populace. A fear that, without someone to make everything “right” again, we will all fall prey to forces beyond our control and die miserable deaths at the hands of those “others”. Maybe I’m biased, but I believe that this whole ridiculous political mess belies a need for better economic education. The concept of a “law” of supply and demand is being thrown around a lot lately, and it behooves us to understand that certain equilibria don’t always work for everyone. And I firmly believe that our current political system does a pretty good job of balancing competing interests. It is perfect? No. Is there money buying policy? Yes. Do transfer payments encourage free-ridership? Sometimes. Should we allow businesses to make mistakes? Sometimes. But hopefully, one thing is amply clear now. “It’s the economy, stupid!” isn’t just an admonishment to political hopefuls, it’s a battle cry that everyone can get behind. And I just happen to think that the establishment candidate understands that the best.

John von Neumann Was a Big Fat Idiot

The fact is that we Humans do most of the things that we do without any conscious cognitive intervention whatsoever. And that means that we Humans make mistakes. And not just once in awhile, but all the time. I know that I, for one, make utility-destroying choices every day. Just today I went to a grocery store for eggs and milk and came back with several other items including, not one, but, two bags of Australian licorice, which I regret buying because I have already gained 5 pounds since starting my PhD program due to eating such things and sitting for longer periods of time while studying. I am currently sitting at a computer at nearly 11 pm and I have promised myself to go running in the morning to try to shed these pounds, so I regret being up late. Let’s see... what else... I disappointed my son by choosing to go to a different event than his water polo match, I blew off making dinner (to go to the grocery store) and so we ate out which meant that we spent more money than we would have if I had waited until after dinnertime to go to the grocery store, and I wore horribly uncomfortable shoes to the event I went to earlier and I now have a blister on my pinkie toe.

Eat the Salad! - An Introduction to Irrational Economics
Tradeoffs
A foundation of economic theory is the concept of trade-offs. What economists observe in the way of how you make these trades-off are your choices. Understanding the phenomenal complexity of even a single choice, however, is impossible, and so economists make very simple, but very powerful models. These models use the observations of your choices (your purchases, for the most part), along with statistics, to interpret and predict your behavior. And the models do an awesome job... in the aggregate. The models, however, rely on the Von-Neumann/Morgenstern axioms of rationality. What these axioms do is make it so that whatever you choose is rational, mathematically anyway. But behavioral and neuro-economists are kinda throwing a wrench into the whole model thingy by extracting economics from the math and making it more "Human". In other words, they introduce the possibility that people behave irrationally. Whoa! Are you okay there? Well, then get back in your seat after that shocker, folks, 'cause I'm gonna dig in a bit here.
"Choice. The problem is choice." - Neo
When we all make choices, we are usually not rational. At least not in the mathematical sense. You see, in order to qualify as rational, you have to become an "Econ". A being with perfect information. You know all of the prices and costs of things everywhere and you can easily foresee the consequences of all your tradeoffs in the immediate AND DISTANT future. But as a "Human" your senses, personal history, memories, your mood, your habits, the environment you are in, your level of alertness at the moment, your level of creativity in the moment, among thousands of other factors, all come in to play in a single choice - not the least of which is the information you have at hand about the particular subject matter pertaining to the choice. I made the video above to point out that the specific nutritional points made by the fear-mongering media would actually have you make a worse choice at a fast food restaurant. But thinking people who know that vegetables are better than hamburgers can still make a good choice. [I'll ignore the fact that if you chose the burger it is HIGHLY likely that your meal will also include a bunch a French fries and a soda automatically unless you override THAT choice with ANOTHER set of choices.] [Duly ignored.]
Me, Myself, and I - Decisions versus Choices
It is a common adage that what you don't know can't hurt you. But people often misunderstand this aphorism because it is meant to be ironic. When you walk into a fast food restaurant the smell will embed unconscious decisions in your brain to target high-calorie, high-fat, high-salt, high-sugar foods since these things were hard to come by in even our very recent (say, the past 5,000 years) history as human beings. And "Me" doesn't "know" it. It is unconscious, which is, by definition, not able to be rationalized. So go easy on yourself when you realize that "Me" made choices in the past that "Myself" (the parts of the brain that deal in quick absolutes like "right" and "wrong") could have made better, it was your "Me" brain, not your "Myself" brain that made the choice. "Myself" was asleep at the switch letting instinct and habit have their way. And lest you think those are the only two people in your head, let me introduce you to "I" the one who deliberates rationally about everything and tries really hard (sometimes, too hard) to reconcile between "Me" and "Myself". This mess of people are your "Board of Directors" and, believe me, unless "I" is involved in helping to make a choice in the moment, either "Me" or "Myself" are going to make a snap decision and you will open your mouth or move your hands without much, if any, thought behind what you are doing. And here's the kicker. The fact that those guys can make good choices sometimes makes you confident that "I" is just a time-waster. The deliberative, analytical thought that "I" uses has to overcome thousands of years of "Me's" instincts to compete for whatever resources it can get immediately and "Myself's" snap judgements that rely on faulty memories that often aren't even applicable to the current situation and start using up everyone's time and brain-power, even physically overwhelming "Me" and "Myself" (using a flood of neurotransmitters in the frontal lobe) to arrive at a better decision. And then, somehow, "I" has to make you make a good observable choice - like choosing to gather more information (for instance, reading the ingredients list on the whole meal) or walking out and finding a place with ONLY salads.
TMI - Good Thing or Bad Thing?
Your brain makes thousands of decisions for you of which you are unaware, which is a good thing because society likes it when you decide to wear a shirt to work. But it is also a very bad thing when it decides that it should just rely on the information it has at hand to make more important decisions, like whether or not you should drive the speed limit if everyone else is moving faster, whether you should move to a new city in case the industry you work in pays better there or you would like the lifestyle there better, or when you are choosing between a salad and a hamburger for lunch. Until you can take the decision away from the subconscious and the conscious-but-quick-to-decide parts of your brain and begin to deliberate over it, you won't always win those fights. Remember, making a rational tradeoff implies that you were aware of all of the alternatives and their ultimate consequences and made a choice based on that information. This is almost never the case. I chose to complete college so I will never know if I would have been better off quitting to go be an actress. Based on this video, I'm saying college worked out pretty well for me.
What I can know is that I have to eat to stay alive and if I think back to what it was like before mass produced and distributed food systems, I can figure out that food was probably relatively scare not that long ago (it wasn't readily available everywhere like today in the first world) and limited in variety. Food was probably largely restricted to minimally processed (think butchered or picked as the only processing), and so also didn't have many calories added on to its original form. But nowadays I don't have to think to generate information. The world brings it to me magically. In short order, I have learned LOTS of information - scientists have discovered that my body needs fat and protein and salt and some carbohydrates and vitamins and minerals, and lots of things that I can't see. Scientists are awesome at making the otherwise invisible known. But that information escapes out into the "media" and now all that information seems to make things more complicated and "Me", "Myself" and "I" could get into a knock-down drag out about what is the best decision until two give up and one gets their way. The funny thing is that all the information is hard for "Me" to process, after all that's "I" job, but "Me" also "knows" that all the "Good Things" my body needs comes in fresh veggies and fruits. She's just forgotten since there are SOOO many other options available. "Me" knows that her body is built so that she can move around, "Me" knows that those cute shoes are going to hurt, and "Me" knows those newer golf clubs aren't going to improve my swing. But "Me" has a tendency to think shiny, new, and now are the main objectives. Those are "Good" and, remember, "Myself" is easily talked into "Good". Which is often bad. "I", the reasonable voice in your head, thinks functional, tried-and-true, and long-term, but is often not thinking long-term enough so that you can go full circle and get back to the choice you have to make right now without a battle. Emotions are the weaponry in these battles and they are indiscriminant - like WMDs. Once emotions get involved "Me" Myself" and "I" entrench, that is, they get IRRATIONAL, and nobody wins. Your emotions are very primitive features of your brain and they make you behave like Kim Jong Un on crack. And that's always bad.
The Game of Tradeoffs
What economists have come to incorporate into the idea of tradeoffs is the idea of risk. When Megan McCarthy was asked about her eating habits, she noted that it was a risk for her to tradeoff a hamburger and French fries for a salad because she "could get hit by a bus tomorrow". This was, of course her "Me" and "Myself" attempting to playout the game of life as though it would be concluded in the next 24 hours. If "I" wants to make a rational decision, whether that decision is about food, education, a job or career change, or a chuck-it-all-I'm becoming-a-beach-bum decision, "I" has to think about the risks of the consequences of the actual choices into the far future and use cold facts and hard logic to convince "everyone" involved of its position based on its assessment of the risks and rewards (remember a reward is as much a consequence as a bad result is to any choice).
Consolidating the hapless, Freudian trio into one single "Human", it should be clear that we non-Econs often make decisions based on very little information, or information that is so woefully limited that if we knew even the amount of information we didn't know pertaining to a single choice, we'd be utterly stymied and probably end up catatonic. Life is a hard game to play when most of it is in a black box that we give to the triplets to shake and see if they can figure out what we should do next. All The Geekonomist can tell you is this: The risk of you dying tomorrow is really, really low. Eat the salad!

Dr. Michael Burry - The Big Short’s Biggest Jerk
by Jacqueline Verrilli
1) FASBs are easily gamed
2) Small print should be in BIG, BOLD LETTERS!
3) Fear the acronym!
- Originate mortgage loans (don't worry about the quality of the loans because...),
- Sell mortgage loans to other entities like investment banks (get them “off the books”).
- Investments banks put all the loans into an aggregated “pool” and create bonds or Mortgage Backed Securities (MBS) (oh, yes, we must have an acronym here!).
- Get MBS bonds rated by a rating agency to get a percentage of the bonds blessed as “AAA” rated (WOW! Triple A! They must be good!), and a percentage of them rated “AA”, and so on. Give “AAA” rated bonds the lowest interest rates, since they are the most secure, and give “BBB” rated bonds (which still sounds pretty good, doesn’t it?) higher interest rates since they are more risky. The percentage left unrated used to actually be honestly-named “junk bonds”.
- Sell bonds to investors. This is where all the good small print and legalese gets inserted into the documents with statements like “these investments were rated by a third party and do not imply or reflect the opinion of the issuer as to the quality of the investment” and “the underlying cash flows from these investments is drawn from a pool of residential mortgages originated at institutions other than the issuer…”
- Take all the bonds that don’t sell (including the junk) and re-bundle them into a CDO!!!!!!!!!!!!!! Let’s recap up to this point. The original loan payments on mortgages that went into the MBSs are now re-pooled and re-bonded. So, a CDO is a bond made up of cash flow off of bonds made up of the cash flow off of mortgage loans that were originated and sold by a bank. You still with me? OK. Good. Cause then…
- Have the CDO rated by an agency to see what percentage will be deemed “AAA” “AA” “A”… and sell those, too. Or hold onto them since they have fairly high interest rates as well as high ratings!
- Sell people like Dr. Michael Burry “swaps” to make extra money and create “riskless” assets and get those CDO/Swap combos “off the books”.
Acronyms and jargon are super-efficient in meetings and reports where everyone is already “in the know” on the obfuscation. But whenever you hear or read an acronym, jargon, or some seemingly innocuous words thrown into a sentence that act to trivialize the discussion, you should instantly be wary and be prompted to ask this “stupid” question:
