Mode of Doing

Take Action!
After spending 15 years in education, I spent a brief two and a half year or so working (2 years in the military and then 6 months in the private sector). I returned to education after that; almost completing my first year of education since the hiatus. So I guess I know a thing or two about studying, or at least learning. Of course, everyone have different styles of learning but from my experience with people around me (who have mostly done remarkably well in the education system back in Singapore), studying/revising for school work almost definitely involves some form of active 'doing' rather than passive stuff (like plain reading).
The trick to absorbing new materials and learning in general is to involve as many senses as possible. This is a concept I explored a while back in 'Remembering Stuff'. It is then, more sensible to draw mindmaps while reading, to do underlining, annotations, taking notes while going through materials. When I go through my Economics notes, I often have to try deriving the equations myself because if I don't walk myself through the equations using my own interpretation of the logic of the theory, I will never be able to internalize the materials. This true for all the hard sciences (granted, economics is not exactly a hard science but when it comes down to the equations and formulas, we can reasonably assume it takes on that slice of nature of hard sciences).
But what about social sciences and humanities? It helps to draw mindmaps, basically to make connections between things that are studied. And the best part about mind maps is that it allows you to make many different complex connections. Although at the end of the day you might not actually find the stuff you drew particularly useful, the mindmap is really more of a tool to pin down your thinking of the connections than a visual representation of the actual concepts (especially true when you're doing revision) so it's fine. Getting in the mode of 'doing' activates your kinesthetic self and enlist the help of your muscles to 'remember' stuff for you. It's not that the muscle cells helps you to remember stuff but that the motor neurons help to provide another channel by which the new material enters your brains.
All that busyness also keeps you engaged and focused, especially if you're like me, dozing off easily as I stare at my materials. So for those who are studying out there, preparing for examinations, plainly trying to be consistent, don't waste your time staring blankly at your notes. Take some action and learn something.
Disturbed Mind

A Little Push...
While we often think that behaviours of humans are more often shaped by oneself than anything else, and that perhaps all psychological issues stems from innate factors, there appears much cases of the otherwise. Apparently, it now appears that a common parasite of humans could be responsible for behavioural changes in human beings and even some psychological issues. Even then, Toxoplasma gondii should not be an excuse for any sort of such problems one faces.
The concept that humans are mere expression of genes and subjected to the whims and fancies of little parasitic organisms, cells and organelles or even the greater, more subtle system of evolution is naturally disturbing. It is important that we do not see things this way. Even though we can be prodded to do things we think we have decided to do purely out of free will, we are very much in control. Richard Thaler's Nudge gives us a good sense of what tricks us and what sort of weaknesses we have and how we can discipline ourselves to make the choices we truly want to make and live a better life. In that sense, we remain in control.
Richard Thaler is one of the behavioural economist whose research and experiments have been widely quoted by popular economics and sociology books. Journalist like Malcolm Gladwell probably loves him and so do other economist book writers like Tim Harford and Freakonomics author Steven Levitt.
Free Market Madness
By Kevin

Market for Sanity
I was looking for George Arkelof and Robert Shiller's Animal Spirits in the library but it was on loan so I decided to look for something else in the Call Number 330 (which some library-goers might note is the 'Economics' section) area. I stumbled on 'Free Market Madness' by Peter Ubel.
Ubel's book is a pretty simple and short one, I took only one and a half day of on-and-off reading to finish it, one of my fastest timing for a non-fiction. Admittedly, the text and paragraph spacings are pretty wide and the book is thin for a hard-cover one. It is largely about behavioural economics, a topic which I hardly have a hard time understanding so the speed by which I finished the book didn't really surprise me. Nevertheless, I hardly consider Ubel's Free Market Madness to be that good a book.
For a start, I understand that Ubel is trying to make a case for government intervention in the economy for markets where consumers are ill-placed to make wise choices and where market imperfections like the inadequacy of useful information and the apparent misalignment of producer's interests and consumer's interests are significant. He focuses on the case of junk food causing obesity though he touched on other cases such as insufficient retirement funding and overspending on branded drugs. Unfortunately, while he makes a good case for the fact that humans are not entirely rational (something we all know at least implicitly), based mainly on the study of other behavioural scientists and economists, he didn't give very outstanding or original proposals on how to get around this problems. Even then, he fails to make a good connection with how the conflict between the short-term-self and long-term-self can be resolved by the governments; the question of what sort of happiness/well-being (long term or short term) the 'Big Brother' he is advocating should maximize it left to speculation by the reader.
The little technical issues in the examples he cited in his book is by and large criticized by David Gordon, senior fellow of the Mises Institute. Austrian School economists probably think that no one can be innocently obese; it takes two hands to clap and producers and consumers must agree on the transaction for it to take place. In other words, people are obese through a process of attempting to maximize utility within their own accounting. On the other hand, Ubel thinks that the faculty accounting on the part of the consumers need to be rectified - in other words, internalities need to be addressed. The problem is we cannot exactly agree on which accounting is correct; after all, if one's belief in the goodness of a product can provide additional positive experience in consuming it, the faculty accounting can have such a self-fulfilling effect. I believe I have the tendency to agree with the ordinary economists that humans would have a fair degree of foresight and self-control and in an event where they lack such discipline and ability, the market punishes them very much in the way evolution eliminates those who lack the fitness.
His proposals are rather unoriginal, citing stuff like fat taxes once mentioned in The Economist, default options, persuasion campaigns (largely moral suasion) and possibly outright ban. He did discuss implications on liberty and such but doesn't dwell much on it - often it seems to me like he's saying 'I just want everything to be good and right, I don't care how'.
I do agree with Ubel, that humans in our age needs more self-control and the public's awareness of the ills of the markets, the ills of different products that are so ubiquitous in our world today needs to be improved. This self-improvement in discipline and improvement of public knowledge can come from bottom-up rather than top-down. After all, given the circumstances today, it is likely that the group with better knowledge of the markets, those making wiser market decisions and the ones who have better self-control is going to thrive. Parents will have to recognize that and respond accordingly (not too much to hope for given the limited rationality of humans I hope) when educating their children and developing them. And I must have to say that in markets like healthcare and pharmaceutical products, doctors like Ubel himself will have to take the responsibility of protecting their patients from the ills of the market/industry. The imperfect information is really too serious in this market and Ubel is right to say that doctors are practically making decisions for patients - doctors' recommendations are almost equals to patients' choice (doctors can't possibly give their diagnosis to patients and get them to choose medicine for themselves). The government can only do so much to protect the doctors from manipulation by the industry and thus defend the interests of the patients. Physicians themselves will have to take the big step to be responsible doctors.
On the whole, Free Market Madness gives us good idea of how behavioural economics came into being and how traditional economic analysis of indifference is difficult to apply in today's complex world. As a result, rationality of human beings becomes undermined today. Beyond that, it makes a good alert on the problems humans might have with markets that makes us poor economic agents - in long run we will get exploited somehow. We will need to exploit back by becoming producers of certain exploitive products ourselves or try to defend ourselves through self-restraint and aggressive self-education. Otherwise, if the book is hoping to inspire any sort of action, it might need to be much more.
Another Week

Another Week Mail
The weeks seems to be passing faster as the entries on ERPZ becomes more frequent. The one-entry-per-day rate now is not exactly very sustainable without additional support from guest writers and contributors so I'm once again calling out for interested parties to leave a comment with your emails so I might be able to contact you and get your contribution up.
This week's reading delves into some less-read areas, namely consumer choice. Knowledge@Wharton recently ran an article about How Assortment Size Influences Healthy Consumer Choices. Earlier, they discussed how environmental cues influence consumer choice too.
The linked article mentioned about the 'paradox of choice', which is the topic of Barry Schwartz's talk on TED.com. He explains the disadvantages of being offered too many choices and the problems associated with the implications of having too many choices in the first place on the psyche of the person after making the decision, citing Dan Gilbert's presentation in the same TED conference.
Barry is another great speaker, mixing humour consistently throughout his talk with a steady flow of cartoons. The point he makes in our escalating expectations is very real and worth pondering over for anyone who wants to exert discipline on their thinking to keep their mind healthy. He claims he wrote the book, The Paradox of Choice to explain to himself why he felt worst when he got a better jeans than he previously did.
Life By Numbers
By Kevin

Nike+iPod Set
In this Wired article about The Nike Experiment, the power of living by numbers is demonstrated by the tracking device, Nike+ that is designed to provide runners with information (actually only speed and distance) of their runs.
Thanks to the article, I also got to learn about the Hawthorne Effect, which suggest that studying subjects would cause them to improve their behaviours as a result of their awareness of being observed even if they are not told what they are being studied on. Intuitively, it kind of makes sense and at a personal level when you are able to track data about yourself and monitor the figures, you'll tend to behave 'properly' so to speak. That goes to show that more often than not, discipline can be improved through feedback. Of course, for one to act upon the feedback, one must also trust it and people normally have no feud against raw numbers. That is what makes Nike+ such a success.
