Review of Depression Economics - September 24, 2009
Depression
economics is written by Paul Krugman, is a Nobel Prize winning
economist. Having suffered though a number of economics courses in
university, I was bracing myself for an onslaught of mind-rotting
formulas, matrix algebra tables, and insomnia curing prose. Thankfully,
this book turned out to be one of the more enjoyable and informative
economics books I have ever read and a refreshing change from most of
the current economic commentary. I should point out though that readers
should not expect an in-depth analysis of the current crisis as much of
the book was written over ten years ago but was updated in 2009.
Nevertheless, it does give a fantastic, easy to understand explanation
of how recessions like the one we have just experienced actually
happen.
Many of the opinions on the Great Recession (as the
crisis appears to have been christened), and on most matters related to
the economy, are like a stew containing equal parts predictability,
superficiality and bias. This is likely due to the fact that people
have a tendency to want to assign blame for every economic and societal
problem. Listen to any cable news station and you may notice that every
analyst seems to have a very simple cause that conveniently fits into a
short sound bite. The most popular theories include excessive greed on
Wall Street, real estate speculation, and at times even capitalism
itself.
Anyone looking for someone to blame for this recession
will be disappointed. Mr. Krugman shows that recessions are a natural
part of a free market system and can happen without greed or
corruption. A sign of great intelligence is when you can explain
complex problems to ordinary people, and Mr. Krugman does that with his
description of how a recession occurred within a babysitting club in
Washington DC.
This was a real case where a group of couples
came up with a system to share babysitting duties. When a couple
babysat for another couple, they would receive a coupon that they could
pay another couple to babysit for them in the future. Couples were
issued coupons at the beginning so that they would be able to get
things started. Because couples would have to babysit to get coupons,
the system ensured that over time everyone would do an equal amount of
babysitting. Surprisingly, without any greed or corruption, a serious
recession in babysitting occurred. This happened because the couples in
the group wanted to babysit and build up coupons because they felt they
did not have a large enough reserve. Everyone in the group wanted to
babysit, and in fact, everyone wanted to go out, provided they had
enough coupons for future use. The problem was that they didn’t have
enough. The problem was eventually solved when the group issued more
coupons. Once people felt they had enough coupons in reserve, they
started going out again, which meant more opportunities for
babysitting.
Mr. Krugman makes the point that this is very
similar to what happens in the real world and argues that most
recessions can be fixed by central banks simply printing more money to
make people willing to start spending again. Throughout the book, he
criticizes the IMF in how it handled many of the third world crises of
the 80s and 90s. In those days, the IMF imposed stringent monetary
policy at a time when Mr. Krugman argues that the countries, like the
babysitting club, should have been loosening policy and printing more
money. As a side note, anyone who has read his column or watches his
television appearances would know that he has used the same reasoning
in arguing for a large fiscal stimulus to confront the current
recession.
Depression Economics provides a thoughtful and
comprehendible analysis of the causes of recessions and is a refreshing
read for anyone who has become tired of the rhetoric on the current
crisis.
Confessions of a Wall Street Analyst - book review, July 15, 2008
In
Confessions of a Wall Street Analyst, former top-ranked telecom analyst
Dan Reingold provides some interesting insight on the workings of Wall
Street analysts, and it is not a very pretty picture. The book is
written in the years following the bursting of the tech bubble, so
while his account of rampant conflicts of interest among analysts is
appalling, it is essentially old news here in 2008. Nevertheless, Mr.
Reingold has crafted a compelling story that provides behind the scenes
details that you would not get from reading newspaper articles.
As I have said before, I generally
enjoy it when authors rip on someone, and Dan Reingold did not
disappoint in this book. If there is one underlying theme throughout
this book, it is that Jack Grubman was horribly corrupt and nowhere
near as good an analyst as Mr. Reingold. More civilized readers than I
would likely find this excessive, but I found it spiced up what many
would consider a rather pedantic subject matter.
For me, what sets this book apart
from almost any non-fiction book you will ever read is Mr. Reingold’s
honesty. With almost no exceptions, authors who recount a story in
which they were involved invariably portray themselves slightly more
positively than the New Testament portrays Jesus. Mr. Reingold candidly
admits to some examples of where he made mistakes and where his
performance was lacking. This may not sound like much but you will have
to read at least 1,000 books to find an author who recounts a story
about himself in which he does not come across as a saint.
Honesty aside though, after reading
of his successes and failures, I cannot truly say that Mr. Reingold’s
analysis provided any more value to investors than a blindfolded monkey
randomly assigning buy and sell ratings. Given that a blindfolded
monkey would have made an equal number of sell ratings during the
bubble, you could even make the case that the monkey would have
provided more valuable recommendations (because he is not here to
defend himself, I should point out that Mr. Reingold provides an
explanation in his book as to why sell ratings are so much rarer than
buy ratings). This sounds like a cheap shot at the author, but it is
not my intent. My point is that the market may be so efficient that
analyst buy and sell recommendations in general may not be nearly as
useful to investors some would like to believe.
Whatever your view of stock market
analysts, if you have an interest in the stock market you will likely
find Confessions of a Wall Street Analyst to be a fascinating and
entertaining read.
India Arriving, by Rafiq Dossani - book review, May 19, 2008
As the title indicates, this is a book about India. If you would like to learn more about India, you should definitely consider buying this book. If you are also the type who prefers a book that focuses on its subject matter and does not get distracted with attempts at humour or occasionally wandering off with interesting but tangential anecdotes, then this will be required reading for you.
It is difficult to criticize India Arriving, but I will give it a shot. This book is very utilitarian, similar to a well made, reliable toilet or pair of toenail clippers. Rafiq Dossani gets a passing grade for technical merit but a zero for artistic impression. The author appears to have lived a remarkably interesting and accomplished life, but somehow manages to come across as dull and boring. While he has certainly done many interesting things in his life, Mr. Dossani is now very much an academic and this book reads much like a textbook on Indian history and public policy. Luckily for the general public, but unfortunately for his publisher, nobody can force you to read his book. I realize I am being somewhat unfair, but I generally like authors who sprinkle plenty of interesting anecdotes throughout the book or rip on someone or something. This book offers neither. I did get the sense though that deep down he would like nothing more than to take a few shots at the Chinese. At one point in the book he discusses how it is “puzzling” that Indians have been so disproportionately successful in Silicon Valley. I can’t help but think that he does not find this puzzling at all, but believes that the true reason is that Indians are smarter than everyone else, in particular the Chinese, but he is too professional to write it. In the author’s defence, there are a few sections of the book where he becomes less professorial, particularly when discussing the Gujarat riots. This is the one part of the book that is likely to be viewed as controversial.
While my concerns with the book are mostly stylistic, I do have a few issues with the content itself. While I most definitely learned a great deal from this book, Mr. Dossani devotes more time to dull public policy issues (in particular as they relate to information technology) than to deeply important events in Indian history, such as the wars with Pakistan. This is fine if you are from India and know those topics inside out, but it is a drawback for an outsider such as myself trying to learn about India. The most frustrating example of this is in the author’s discussion of the caste system. He provides an overview of what it is and discusses some of the political implications of the system, but he does explain how this system actually began. India is the only place in the world that has such a formal and historical classification of its people. Surely an understanding of why such a system took root in India and has persisted for so long would provide valuable insights for investors or people doing business in India.
On balance though, the content of the book is solid and the author’s points are well presented. The section on the history of the Indian stock market was particularly interesting for me, not just because I am so interested in stock markets but because the author has a great deal of practical, firsthand experience with the Indian exchange. If you are only going to buy one book on India, I would consider looking elsewhere. However, if you have a keen interest in India, and are not expecting a riveting page turner, India Arriving is worth reading.
A Random Walk Down Wall Street - April 27, 2008
If you publish a website called blindfoldedmonkey.net, it is mandatory to speak highly of “A Random Walk Down Wall Street”. This book goes to the very heart of the reason I have blindfolded monkeys picking stocks every quarter. If you are just getting involved with the stock market and are considering buying stocks or mutual funds for the first time, I can think of no better book to recommend. The primary thesis of the book is that the stock market, while perhaps not perfectly efficient, is efficient enough so as to make it highly improbable that any individual investor or mutual fund manager will consistently outperform the market over time. If there is a golden rule in investing, this is it.
One of the things I admire about Mr. Malkiel is that he is not completely dogmatic in his views. While he makes a compelling argument that the movement of stocks is largely random, he does acknowledge that there have been many cases were this randomness has been violated. He does qualify these examples, however, by showing how factors such as transaction costs and taxes can make it difficult to consistently exploit temporary non-randomness in the market.
The book discusses some of the most common techniques used by investors to beat the market. While he takes the stance that none of these approaches will allow you to consistently outperform the market, fundamental analysis is presented as the best, or least bad, method. The author acknowledges, correctly, that fundamental analysis will at least prevent investors from being caught up in the most obscenely inflated stock market bubbles. Not surprisingly, the method that gets the worst treatment is technical analysis, which involves predicting a stock’s future price movement based on analysis of its past price movements. Technical analysis, despite its name, is the least scientific of all investment methods and so it is the easiest target for an academic like Malkiel. By far the best point he makes though is that technical analysts never seem to have much money. The richest man in the world uses fundamental analysis but technical analysts, according to the author, tend to have holes in their shoes and frayed shirt collars.
While I admire Mr. Malkiel’s ideological flexibility, there are certain areas of the book where he slips into ideological contradiction. The worst example of this is where he discusses the prospect theory problem of investors selling their winners and holding on to their losers, but later states that stocks that go up in one period invariably go down in the next. Aside from contradictions like these, the biggest shortcoming of the book is that he does not address the implications that the rise of index funds will have on the efficiency, and by extension, randomness of stock markets. Presumably there is some point at which the amount of passive investment in the market will begin to negatively affect the efficiency of markets. This book was written in 1973 when index funds were essentially non-existent. With the incredible increase in passive index investing in recent years, it may be time to stop updating the book and start work on a new one. Whatever its shortcomings, A Random Walk Down Wall Street remains required reading for any investor.
Nuclear Power is not the Answer, by Helen Caldicott - February 11, 2008
I bought this book at the same time that I bought “Power to save the world” because I wanted to read conflicting opinions on pros and cons of nuclear power. On that point, and on that point alone, I was not disappointed. To say that Ms. Caldicott is not in favour of nuclear power would be an understatement akin to saying that Hitler was not much of a Zionist. I like to consider myself a fairly well read individual, but this, by a country mile, the worst book I have ever read in my life. While Ms. Caldicott is a froth-mouthed rapid anti-nuclear crusader, her book did more to convince me that nuclear power may be the way to go than the pro-nuclear “Power to Save the World”.
Ms. Caldicott’s polemic against the nuclear industry has only served to stereotype the anti-nuclear movement as a bunch of fanatical left-wing nuts. This book is an affront to intelligent, open minded people everywhere. I quite literally felt that my intelligence was being insulted as I read this book, and I would strongly caution that anyone who has ever tried and failed to publish a book should avoid reading anything by Ms. Caldicott lest they suffer a massive rage-induced stroke. On the other hand, if like me you have never tried to publish anything, this should give you hope that if she can do it, anyone can do it.
I’m reminded of a little episode that happened way back in high school in calculus class. The teacher had put a problem on the board and went around the class to look at the students’ answers. When he came to my friend, who spent more time passing notes than taking notes, he just stood staring at her answer with a puzzled look. When she asked him if she had done it right he just shook his head said “There is more wrong with that answer than I can express in 50 words or less”, and walked on. I feel like I would need a book of my own to properly critique this book, so I will simply a few examples to give you feel for the type of book this is.
On the cover of this book is a quote from Naomi Klein in which she states that Ms. Caldicott has the rare ability to combine urgency with humor. I did not find any humor in this book, but perhaps that is just me. Perhaps more insightful readers will pick up the subtle humor in the passage where Ms. Caldicott, when discussing the potential effects of a nuclear accident in New York, writes “Consequently, the symptoms that will be experienced by people in Westchester County and Manhattan include: acute loss of hair, severe nausea, vomiting and diarrhea, bleeding from every orifice – hose, mouth, gums, stomach, and bowel – and massive, overwhelming infection.”
The closest that Ms. Caldicott comes to humor, albeit clearly unintentional on her part, is when she says that “the design for an atomic bomb can easily be found on the internet; some basic materials purchased at the local hardware show will complete production.” I find it infuriating that she apparently assumes I will take that as fact and not wonder if there was another body of thought that would suggest it is not so easy to pick up a few things from the hardware store any make a nuclear bomb.
Ms. Caldicott states in her book that every male in the northern hemisphere has a tiny amount of plutonium in his testicles from radioactive fallout that is still falling on the earth from the upper atmosphere, which was polluted by the atmospheric weapons tests…” If she really had a sense of humor, she should have given us a few funny anecdotes from her time spent traveling around North America gathering information on the plutonium content in men’s testicles.
I am someone who actually enjoys a good spirited debate, be it about business, politics, or sports, and one thing I’ve noticed is that when someone resorts to personal attacks and insults it is usually a sign of the weakness of the person’s argument. Consistently throughout her book she portrays her opponents not as fair minded people who have a difference of opinion with her, but as liars or as simpletons who have been manipulated by the nuclear industry and, even worse, the Bush/Cheney administration. In reference to Dr. James Lovelock, a highly regarded scientist and environmentalist who recently came out in favour of nuclear power, Ms. Caldicott but does not mention any of his reasons but instead simply states that he now “wrongly advocates the use of nuclear power as one solution to the global warming crisis.”
I could go on and on with more examples of absurd bias childishness, but there is no need to beat that dead horse. If you have made up your mind that the nuclear industry and all who support it our evil and just want to see someone rant about it, by all means buy this book. If you are someone who wants to weigh the pros and cons of nuclear power, you should look elsewhere. I rate this book 0 out of 5 bananas.
Power to Save the World, by Gwyneth Cravens - Jan 15, 2008
As the half dozen people who have ever read anything on my website are probably aware, I have been interested in Uranium lately, but I’ve been reluctant to buy in because of the tremendous amount of hype that has been associated with it. Rather than just listen to the talking heads, I picked up a couple of books on nuclear power. Because it is tough to find an unbiased opinion of nuclear power, I bought both a pro-nuclear and an anti-nuclear book. The first one I read was ``Power to Save the World``, by Gwyneth Cravens. Ms. Cravens claims to have originally been an anti-nuclear protestor, but like many environmentalists, has come to look at nuclear power as a way of preventing climate change.
The biggest criticism I have of this book has nothing to do with her analysis of nuclear power but rather with the fact that she is primarily a writer of fiction and how clear she makes that fact in her book. I haven’t read any of her novels, but I am sure they are awful. Some her passages are hackneyed and out of place that they are actually comical. Some of my personal favourites from the book include when she tells us that in Albuquerque “the sunsets unfold like a series of long thoughts” and that the “thousands of stars…can inspire contemplation about where we came from, what part we have to play during our brief sojurn, and where we’re going”.
Another problem I have with this book is it is told as a narrative of her various travels throughout the United States touring nuclear facilities, mostly with her friend Rip Anderson, a nuclear power expert and scientist at Sandia National Laboratories. I couldn’t help but get the impression that she was perhaps secretly in love with Rip, or at least wanted the reader to fall in love with him. When we are introduced to Rip we are told that he seems relaxed but is extremely observant, that he likes faded jeans and a Stetson hat, and that he is wiry of build and quick of step.
Despite her tortured prose, this book does provide a great deal of useful information on nuclear power and anyone interested in learning a lot of technical information about nuclear power will not be disappointed. The reader can simply skip over the descriptions of Rip’s clothing and moustache and the philosophical musings.
Ms. Cravens is clear not satisfied with explaining how nuclear power works; she wants to convince us that nuclear power is the best source of energy we have and that much of the anti-nuclear movement is based on fear and ignorance. Some her methods for achieving this are quite effective. One of her more interesting points was that people get exposed to radiation all the time and are not even aware of it. For example, flying on an airplane will expose you to far more radiation than touring a nuclear facility, as will riding the New York subway.
The author’s lobbying for nuclear power runs into trouble when she tries to make the point that even the worst nuclear accidents in history and the scenarios that anti-nuclear activists bring up are actually nowhere near as catastrophic as people are led to believe. She starts off well and makes some interesting points that the fatalities from Chernobyl were much lower than people think and that there were no fatalities from the 3-mile Island meltdown. If she had quit while she was ahead and been satisfied with convincing the reader that will nuclear accidents are bad, they are not as apocalyptic as people often believe. Unfortunately Ms. Cravens becomes overzealous in downplaying these accidents to the point where her objectivity falls into question. She even tries to downplay the severity of the effects on Nagasaki and Hiroshima. Some things are so awful that is pointless to quibble about how awful they are. Whatever the exact death toll and cancer rates, events such as those are horrific events that must be prevented. Her attempts at downplaying those events are pointless and irrelevant to her argument.
Nothing gets under my skin more than blatant, unrepentant hypocrisy and bias. Throughout her book, Ms. Cravens harps on the importance of using probabilistic risk assessment when considering the dangers of nuclear power. Essentially this means not just looking at how bad a particular event would be, but rather the probability that the event will occur. She voices her frustration that critics of nuclear power only focus on the worst case scenario, however, she makes no mention of probabilistic risk assessment when she talks about how global warming could cause the oceans to rise by six feet and kill a billion people. The same goes for the way she states that “coal fired plants cause the deaths of twenty-four thousand Americans per year as well as hundreds of thousands of cases of lung and cardiovascular diseases”, but that we can’t attribute the high rate of cancer near Chernobyl to the meltdown because there are many factors involved.
I don’t know enough about the subject matter to contradict most of what she says, but the one case where I do no better is quite troubling. When discussing some research that was conducted near Chernobyl, we are told that nobody in these hamlets had any identification except name and birth date. Anyone who has spent any time in the former Soviet Union, as I have, knows that this is preposterous. Everybody must carry a passport in these places and anyone can be detained for not having their documents with them. This highlights one of the fundamental limitations of the book; Ms. Cravens is constantly repeating what others tell her and is not an expert in any of the matters she is discussing.
Despite its shortcomings, this book does provide a good technical overview of the nuclear power industry and is worth reading for anyone with an interest in this area. Unfortunately, the author’s background as a fiction write rather than a scientist, combined with her obvious bias, prevents it from meeting its full potential. I rate this book two out of five bananas.
A History of the Global Stock Market
My inaugural book review is of A History of the Global Stock Market by B. Mark Smith. This is a good book for people like me who have a fascination with stock markets. It gives a good overview of the history of markets, providing a variety of interesting stories without getting bogged down in too much detail of any one era or example. The book provides enough detail to allow you to determine if you are interested enough to learn about the various topics in more detail. I found this book to be quite useful for putting current events into a historical context. To steal a line from Mark Twain, history does not always repeat itself, but it rhymes.
The main criticism I have of this book is that although it is ostensibly an overview of the history and development of global stock markets, it becomes apparent early on that the author’s true goal is to present a thesis that stock markets act rationally and to debunk many of the theories of behaviouralists who claim that markets often act irrationally, thereby leading to market bubbles. This would not be such a bad thing if the author approached this debate in an objective way. Unfortunately, it is abundantly clear that while the author seems to acknowledge that markets can be inefficiently priced at times, he had become convinced before writing this book that bubbles as a result of irrational markets do not really occur. The arguments he makes are interesting and valid, such as the notion that investors will knowingly buy an overvalued stock if they believe they can resell it at a higher price, but he fails to acknowledge some famous examples that contradict his argument and glosses over others.
The most blatant example of this is his complete omission of perhaps the most interesting and outrageous bubble in history, the Tulip Mania in Holland in the early part of the 1600s, when people paid extraordinary amounts for tulip bulbs. This omission is even more perplexing given that he references the famous book Extraordinary Popular Delusions and the Madness of Crowds, which he describes as focusing particularly on the South Sea Bubble of the 1700s. While Charles MacKay does deal with the South Sea Bubble, he also goes into some length about the Tulip Mania. Regardless of his motive, the author has lamentably kept his readers from a fascinating and informative story.
Mr. Smith also breezes through the tech bubble, devoting only a handful of pages to it. Perhaps when he wrote this book, that story was still being beaten to death in the papers and therefore felt it unnecessary to go into it in much detail, but for a reader in 2007 it is a definate shortcoming. In the short section of a chapter spent on the tech bubble, he mentions a case where Palm was worth $54.3 Billion, but 3Com, which owned 95% of Palm, was only worth only $28 Billion, yet the author simply cannot bring himself to acknowledge the complete irrationality of this event. While many of his points on bubbles are valid, and in many cases the people are not acting quite as hysterically as they appear on the surface, examples such as Palm suggest that at least on occasion there are instances of irrationality in the market.
Even though this book was not as good as it could have been, I must confess that I had some trouble putting it down and would recommend it to anyone with an interest in the history and efficiency of stock markets. If this book were a wine I would describe it as quaffable. I give it 3 bananas out of a possible 5.
Ms. Caldicott’s polemic against the nuclear industry has only served to stereotype the anti-nuclear movement as a bunch of fanatical left-wing nuts. This book is an affront to intelligent, open minded people everywhere. I quite literally felt that my intelligence was being insulted as I read this book, and I would strongly caution that anyone who has ever tried and failed to publish a book should avoid reading anything by Ms. Caldicott lest they suffer a massive rage-induced stroke.
