Facts and fantasy about the financial crisis

I find it the most lucid summary (and criticism) of almost everything influential that has been published on the financial crisis so far. Some of the books are reviewed too briefly, and some newer ones are completely omitted, but nonetheless I think this is the most concise and useful general-purpose article written on the crisis as yet. Currently you can download Andrew Lo's "Reading about the financial crisis: A 21-Book Review" from his website (PDF version dated Jan 9, 2012). It is prepared for the JEL-- hence you should be able to find it also in one of the their next issues, perhaps in an updated version.

A special mention: the "Fact and Fantasy" section of the article covers the startling misinterpretations (some of them still awaiting to be corrected!), by several prominent academics, policy makers, and journalists, of the 2004 change in the SEC Rule 15c3-1 concerning leverage restrictions of certain financial institutions. It is beyond alarming how fast and easy some of these errors propagate even among what-ought-to-be-connaisseurs-- and how long and hard it takes for them to be discovered and debunked thereafter. The following edifying quote from Lo's article cannot be emphasized enough: 
[...] Only the most neurotic of academics would dig further to attempt to refute a "fact" that jibes with his or her intuition and preconceptions. This example should serve as a cautionary tale for all of us, and underscores the critical need to collect, check, and accumulate data from which more accurate inferences can then be drawn. Without the immutable hard platform of objective facts on which we can build an accurate narrative of the crisis that stands the test of time, there's little hope for scientific progress as the waves of public opinion toss our perspective in one direction or another. This is one of the most compelling reasons to read more than one account of the financial crisis, and to seek out those books that may not agree with our preconceptions, just in case we've been inadvertently misled through faulty "facts".
* update: the selected quote above is from the October 24, 2011 version of Lo's article; it is slightly different in the Jan 9, 2012 PDF version linked above. I have a preference for the older version, hence I leave that one here.

Funniest dating ad ever?

I hate you all. I hate London. I hate books. I hate critics. I hate this magazine, I hate this column and I hate all the goons who appear in it. But if you have large breasts, are younger than 30 and don't want to talk about the novel you're 'writing' I'll put that aside for approximately two hours one Saturday afternoon in January. Man, 33. Box no. 7810.

Romanian article of the week: Dan Tapalaga with "Best of Boc, Blaga, Paleologu"

This blogpost is only for those who can read Romanian (and ultimately really regards only those still interested  in the political life, in particular concerned with various elections, in Romania-- who are less and less every day, including here the Romanians themselves; a by-product of the article linked below is in fact providing a rationale to explain that trend).



Asadar, un articol excelent al lui Dan Tapalaga; as zice probabil cel mai bun din tot ce am citit scris de el in ultima vreme. Nu necesita alte comentarii.


PS. Disclaimer: am o parere in genere destul de buna (uneori chiar prea pozitiva) despre Toader Paleologu, pe care il stiu personal pana la un punct (e.g., vezi aici sau aici-- istoria de la ultimul link fiind probabil rezumata prin "[] I think this is the beginning of a beautiful friendship"), doar ca omul nu intelege ca avantajul sau comparativ e in diplomatie, nu in politica autohtona (eventual la Ministerul de Externe... dar nu a fost si nu este momentul pentru asta nici acum; de fapt si acolo realizez ca am exagerat, exista mult mai multe incertitudini care trebuie rezolvate-- the unknown unknowns...-- decat ambitia personala). Si cine sa ii spuna asta, daca nu cei cu intentii bune, care inteleg ce este acela un avantaj comparativ?... Mais, à bon entendeur, salut!

US Government shutdown menorah

...and some of us were worried about Portugal...

At midnight, if the President and Congress have not reached an agreement on funding measures, the U.S. government will shutdown, referred to as a funding gap, until an agreement is reached to either extend a temporary funding measure or a final budget deal is made.

[...] The last time a funding gap took place was in 1995-1996 when the government experienced a 21 day shutdown.

Oh well, some, like Stephen Colbert, can see the positive side of all this: extinguishing one more candle on their government shutdown menorah (and... wishing for a pony).

On multicore Stata MP performance

Since I am in the middle of some very interesting discussions and experiments concerning this topic: it really does look like the difference in speed between the different multi-core/multi-processor Stata/MP versions is considerable. Right now I am performing a comparison exercise* with my friend and co-author Miguel, where, it turns out, a number of certain estimations with a 8-core Stata/MP 11 take about 10 almost 15 times less real time (I know, I hardly believe it myself) than (almost) the same estimations done with a 2-core Stata/MP 11. Taking the median across all estimations commands in Stata, an 8-core will outperform a 2-core by a factor of 2.28 (NB: this ratio appears to be larger than the price ratio of these two multicore versions!): I computed this figure from other stats available in this 250 pages report on Stata MP's performance.

The next quest should be to assess Stata's bold claim: "From dual-core laptops to the big iron of multiprocessor servers, Stata gets the most out of multicore systems. No other statistical software comes close" (my emphasis in bold). If true, that surely ought to boost Stata's status in the statistics/econometrics community (part of which-- I plead guilty too-- is currently infatuated with using other programming languages like Ox, Fortran, Gauss, Matlab etc, while typically leaving Stata for simple exercises or data manipulation).


*brief update footnote here, for clarification (well, at least part of the clarification..., the huge, factor 10 15, execution time differential remains somewhat puzzling): we cannot really perform this comparative exercise directly, as "(almost) the same" here means  that we do have  identical specifications (and the same software and operating system), but nonetheless different  (very large) panel datasets-- and in this particular case the difference in the structure (specifically, the "connectedness" of the cross-sectional-time series data, but the intention was not to give too many details) of those datasets matters, beyond an eventual difference in  the number of observations (for our purpose virtually the same); if we ran identical specifications on exactly the same dataset, with the 8-core and respectively the dual-core Stata/MP, the speed ratio could not be higher than 8/2=4, the theoretical limit. Given the type of exercise performed here, the real time differential due solely to the difference in core numbers is most likely close to this limit.

What I have been reading

A couple of books I have read within the past few weeks, most of them on my Kindle 3G device(*):

Scott Berkun's "Confessions of a Public Speaker" (get the Kindle edition): the author is a professional speaker, in front of audiences large and small, hence he has got some very helpful tips for anyone who ever needs to engage in public speaking, mostly drawn from his own experiences. These tips range from the a priori preparation for your speech, to engaging your audience, to knowing what to do when you have a too large room and too few people in there etc.What is missing, but understandably so given the author's career, is the treatment of academic public lectures, which can be quite different than any other public types of speech-- nevertheless a series of Berkun's recommendations work perfectly also for academics. The book is at the same time a very fun reading.

***

Jason Zweig's "The Little Book of Safe Money: How to Conquer Killer Markets, Con Artists, and Yourself" (get the Kindle edition): useful advice for small investors (that can be probably summed up by the following quotes "for most small investors, an indexed bond mutual fond is the best way to go" and "[d]on't invest in leveraged and inverse ETFs. Leave them to professional traders" ...) and adapted particularly for the US audience (you do find for instance very helpful info on the so-called '529 plans,' including some online links to compare various such plans, in case you are interested in that). Definitely not for more sophisticated investors (some of you, readers of this blog) or for people who've read much more detailed stuff on financial investments earlier (although I am myself in this category, sometimes it is useful to consult other perspectives at a more elementary level). A tad too cautious and limited on scope and purpose. Anyhow, if you are a beginner and (plan to) live in the US, by all means do read this book.

***

Steven Levitt and Stephen Dubner's "Superfreakonomics" (get the Kindle edition). I find this better written than their first Freakonomics success (see, e.g., the first bullet point here for some of the huge debate on that earlier book)-- probably experience and learning on the job-- though it contains as little economics as the first one (it is written more in an investigative journalism style: Dubner obviously has the feeling for what sells and what not). That being said, I still think it is eventually a great service even to the economics  academic community (at least in drawing attention to the range of situations/phenomena that economics can be applied to; NB: I personally doubt it would give the/a too wrong impression of what economists do and should do-- if anything, it might convey the idea that some economists know very well how to sell their books,), and probably that writing it in more 'econo-prose' would have reduced its popularity. I would particularly recommend it to any non-economists, for sure (e.g. last winter I noticed the Romanian translation of the book is already out, and made it present to a good old Transylvanian friend of mine-- in function of his reaction I might offer it to my parents as well). By the way, related, the Freakonomics documentary is currently available for instant viewing on Netflix (I correct myself: right now their site is down, but it is the first time I do not see it functioning), if you are in US and have access to that service-- I plan to watch it one of the next days.

***

And now to my two favorites in this set: 

John Adams's "Hallelujah Junction. Composing an American Life" (unfortunately not available on Kindle): this is one of the best autobiographies I have ever read, within the musical realm and beyond. Honest, full of wit, style, and extremely informative-- and that to say the least. As somebody who's listened to a large set of Adams's compositions (and working on the remaining ones...) and who regularly follows his blog, I simply had to read his autobiographical piece in order to have access to Adams's detailed perspective on both his  own work and his general ideas of music (composition, interpretation, intrigues, all the hoopla), politics, life, everything... Highly recommended: one of those books that you simply cannot stop reading once you have started. I'll most likely refer to passages or ideas from "Hallelujah Junction" in many of my future blogposts.


Steven Landsburg's "The Big Questions" (get it on Kindle): I will only tell you that this book is from my perspective really scary, in that its author appears to think about  crucial stuff --i.e. mathematics, economics, physics, philosophy, tax policies, trade, sex, religion, life, Universe etc.-- in an almost identical way to yours truly (ok: I should maybe phrase it as "I think almost exactly like him"-- after all he was there before me...). In any case, even if you've known all the time and agreed all the way with everything in the book (though he does cover an enormous range of topics, requiring that you'd be an extremely well read person), Landsburg's exposition is one of the clearest I've ever encountered (this is true also for his previous books, some of them recommended earlier on this blog; I will only say here that I even used an earlier quote from him as one of the "propositions" --"stellingen", in Dutch-- to go along with my PhD thesis defence-- see under IX in this list). In particular, he's got the rare ability to explain in few paragraphs, mainly by means of easy examples and analogies, some highly complex material (try explaining quantum physics or deontological vs. consequential ethics to the non-initiated!), albeit he needs to strip them down to the bare essence (but then again this is a popularizing book, aimed for a wide audience). Landsburg's writing style is also something I personally like a lot: he's got just the right amounts of humor, irony, and even the tiny bit of arrogance (why not?) mixed in his book. Check out also Landsburg's "The Big Questions" blog, something I've followed and enjoyed since its very start. I end with a larger quote from the introductory chapter of "The Big Questions" that is likely to give you a good feeling of Landsburg's 'creed' and goal in this book (as well as the similarity with my own academic training and beliefs, c.f. the scary/eerie part from above):
"[...] I went on to a career of research in teaching in both mathematics and economics, with a little dabbling in physics along the way, but I never lost sight of my fascination with the big questions of philosophy: Where did the Universe come from? Why is there something instead of nothing? How is knowledge possible? What justifies a belief? How can we tell right from wrong, and good from evil? How should we live our lives?
Philosophers have useful ways of thinking about these questions, but so do people  who are not philosophers. Physicists know something about the origins of the Universe; mathematicians know something about the patterns of reality; economists know something about how our choices affect the lives of others, which is not distinct from the problem of distinguishing right from wrong. I've come to believe that these disciplines provide some of the best available tools for chipping away at the problems of philosophy.
When a man  with a hammer tells you that everything looks like a nail, you should doubt his objectivity. When a man who knows some math and economics tells you that the problems of philosophy can be solved with math and economics, you're entitled to exactly the same reaction. But in this case I believe the causality runs the other way: I was drawn to math and economics because they illuminate the big questions. I saw the nails and went out to find a hammer. [...]"


(*)which is absolutely fantastic and you must have it, despite 1. the fact that David Letterman cannot find page numbers on the Kindle books -- and hates it because of that; 2. the fact that each Kindle book costs more if you buy it outside US-- function of the IP address from where you log in to your Amazon account when buying it (before investigating and realizing this, I did actually buy quite a few Kindle books during my European winter holidays-- and ended up paying about 50 bucks more than I would have paid, had I bought them here in the US). In any case, I am the owner of more than 100 Kindle books already (yes, Amazon, I expect some loyalty awards!): given my fairly long commuting time between Lakeview, where I live, and Northwestern Univ in Evanston, I can read up to two or three books in good weeks.

Econlinks: The Freudian interlude

Thursday, February 10, 2011

Ah não ser eu toda a gente e toda a parte!

I've watched it most recently via this smart* video rental & online streaming service called Netflix : a true gem of a movie, albeit one of the most underrated cinematographic creations of the past decades (does not have a RottenTomatoes critics' rating!). This is a Wim Wenders meisterwerk, most of the time my favorite (nontrivial; I hold most of Wenders's movies in high esteem). As a by-product, the film is also an effective branding/ marketing tool for Lisboa, and, by extension, Portugal** --in fact, Wenders's original intention had been to make a documentary about the city; suffice to say that Lisbon Story alone would convince me to place Lisboa among my in-no-way-can-miss destinations.  Some highlights: Rüdiger Vogler plays superbly the confused German sound engineer; even though his effective role here is minimal, Patrick Bauchau is perfect as the elusive film director (alter ego of Wenders himself); while Madredeus's Teresa Salgueiro... well, she is just so unique; around them fascinating Lisboa snapshots-- images, sounds, poetry, music, life: what's a key without a kiss?

Earlier on my live discovery of Portugal. Earlier on Madredeus. Earlier on Pessoa.


* not ideal: so far I could find only about 60% of the movies I was interested in watching, with the post-mailed DVD option included. Given my typically unusual choices though, 60% is not that bad. Something like this is badly needed on European soil, too.
** I am going to claim more: this is eventually a great cinematographic statement for and about Europe itself.

Econlinks: Of (visual) art, old and new

  • The third and the seventh: imagination materialized or Alex Roman's computer generated art. Via Michael Nielsen
  • Staying in CG: meet Julia Map, of Google ancestry. And since we're here, read how the fractals changed the world --which was in a way also part of the obituary to Father Fractal, Benoit Mandelbrot, who passed away a couple of months ago; see a better one from the Economist. My own brief memories of him: I met Mandelbrot at a workshop on economics with heterogenous agents (WEHIA) at Essex University, back in 2005. Before his keynote speech, he introduced himself in the following very humorous way (paraphrasing): "Hi, I am Benoit Mandelbrot. And I am not dead yet. [pause] I tell you that because I have just met somebody in the corridor who told me: 'OMG, you are Benoit Mandelbrot. I thought you were dead for a long time now' ". 
  • Meet Jeremy Mayer, tamer of the typewriter. "I disassemble typewriters and then reassemble them into full-scale, anatomically correct human figures. I do not solder, weld, or glue these assemblages together- the process is entirely cold assembly. I do not introduce any part to the assemblage that did not come from a typewriter"
  • Back to the traditional, but impressively executed: meet Camille Seaman. From the "Last Iceberg series" statement: "Nick Cave once sang, 'All things move toward their end.' Icebergs give the impression of doing just that, in their individual way much as humans do; they have been created of unique conditions and shaped by their environments to live a brief life in a manner solely their own. Some go the distance traveling for many years slowly being eroded by time and the elements; others get snagged on the rocks and are whittled away by persistent currents. Still others dramatically collapse in fits of passion and fury."
  • On the art of fiction: interview with Michel Houllebecq, born provocateur. Hat tip MR.
  • And yes, she is back online (hopefully she is now here to stay)! Meet my friend Anna, talented photographer and undercover economist.

The quest for good old kiełbasa in the Big Apple


We ventured out to the Polish neighborhood yesterday. Nothing as compared to Chicago, but nonetheless good sausages. But after five minutes we went to the wrong direction, and ended up in a derelict, post-industrial nightmare instead of lively Polish ladies selling imported toilet paper.

George Stigler could do anything--anything but be boring

 [...] I must out of courtesy and caution reserve judgment on any laws that Professor Stigler may unveil. For, as I learned when our friendship began long ago, George Stigler can do anything-- anything but be boring.
-Paul Samuelson-

Here's the Sunday read I recommend to you: a great 1963 dialogue on the "proper economic role of the state" between two intellectual giants, George Stigler(*, **) and Paul Samuelson. More actual than ever. If only all current policy and academic debates had this flavor!


* inspired by Steven Landsburg's recent blogposts on Stigler, here and here. Echoing Landsburg, you must absolutely read Stigler's "The Intellectual and the Marketplace" and "Memoirs of an Unregulated Economist", if you haven't already done so. Indeed, he would likely be the champion of all Econ bloggers.

Econlinks: The 'Economics and Reality' edition

  • Harald Uhlig has an interesting recent paper entitled "Economics and Reality"  (intentionally recalling Sims's 1980 ECMA, indeed) . While he discusses the relationship between Economics and Reality (yep, isn't that what you all hope to hear?) mainly in terms of Macroeconomics (you know, the black sheep of the family), I thought he does that in an informative and at the same time very concise way. Hence, highly recommended; I'll quote his end (optimistic, for once...) summary, to get you in the mood: "Reality, i.e. empirical evidence influences economic thinking and theory and vice versa -- but it does not do so in textbook fashion. Jolted by new empirical and theoretical insights and subjected to the fickleness of attention, the frontier of our sciences lurches forward to the unknown territory of ever more profound understanding. If it moves in circles, it hopefully does so on even higher levels. Practical economics and economic policy follows, with considerable distance. Perhaps, this is how it has to be."

Flawless: Kseniya

I have not seen anything more dramatic and powerful than this in the modern art world perhaps since Pink Floyd's The Wall movie. This is a work of perfection, there is no single detail left to chance; for instance, obviously it could have only ended apocalyptically-- on Apocalyptica's version of Nothing Else Matters.

After this, what is left for us to write? I bow in front of the real talent.

Blog birthday. Senses. And jazz.

Born in the anonymity of the blogosphere 5 years ago, this weblog grew up a curious, motivated, and responsible toddler: its (no longer) secret ambition remained no less than saving the world-- despite repeated trials of dissuasion by its author, who once foolishly pledged allegiance to the infusion of blogs about nothing. Thus, as this blog claims and proved a certain maturity, it will receive two significant presents for its half decade birthday. To be shared with its select audience:

  • a second perennial motto, see blog footer; David Hilbert's Optimismus in der Forschung (und in das Leben!) is joined by Giacomo Casanova's raison d'être.
  • a wonderful, complex, complete musical masterpiece; Chicago right now feels almost as dim and rainy as Barron and Haden's flawless "Twilight" in NYC.

Wine of the Year: Saxum, James Berry Paso Robles 2007

I believe it is the first time since I know it-- though it might well be first time ever--that Wine Spectator's top 10 is dominated by New World wines. The winner is Saxum, James Berry Vineyard Paso Robles 2007, "[a]n amazing wine, dense, rich and layered, offering a mix of power and finesse, with concentrated dark berry fruit, mineral, sage, herb and cedar notes that are pure, intense, focused and persistent. Grenache, Mourvèdre and Syrah. Drink now through 2018" . So we shall!

All in all, there are 5 Californian and 2 Australian wines in top 10, while the old wine powers  (Italy, Portugal, France) have representatives relegated only to places 8-10. I have not tried to date any of WS's 2010 top 10 choices, but this set is so intriguing that I am gonna start getting hold of these wines right now. Remarkable as well is the fact that the French wine selected, a Clos des Papes Châteauneuf-du-Pape, is-- you will hardly believe-- a white, from 2009 (which costs precisely 100 bucks a bottle). That is what I call success of this brand: recall that the 2007 wine of the year was a Clos des Papes Châteauneuf-du-Pape '05; moreover one of my favourite wines ever (arguably, influenced by the ambiance and entourage in the place where I have tried it last) was an egoist  Clos des Papes Châteauneuf-du-Pape '06. All reds: high time we tried their top white, indeed.

Finally, two more brief notes: a) in the full top 100 for 2010, there is a splendid Hungarian wine, which I have tasted a couple of times-- and I am glad the WS editors have eventually discovered it-- a Royal Tokaji Aszú 5 Puttonyos red label from 2006, on position 28-- if you're passing through Budapest, do not leave without it;  b) one of the only two wines in top 100 to obtain the absolute 100 tasting points (the overall ranking is established on more than pure taste assessment-- what I do not particularly like, but well...) is the Dow Vintage Port 2007 (14/100). Now, people who know me well will be able to confirm that I am the biggest fan of Dow's 1994 vintage, hence if the '07 is acclaimed by WS as "[t]he greatest Dow ever made", I look forward for a touch of the sublime, no less.

Hup Holland Hup!

With a very pertinent quote from my good old friend Robert, which best summarizes what needs to happen tomorrow (today, if you are on European soil):


Indeed, the defence is crucial, as is violence on the midfield. For the first time in years Holland has a pair of complete bastards in the midfield (De Jong and Van Bommel). They will have to break down the Brazilian attack while Sneijder finds space behind the Brazilian wing backs to launch Robben and Van Persie. Doesn't sound very traditional Dutch, right? But it will be the game plan tomorrow. Believe it or not, some people here are actually calling for an old fashion German style approach, which is causing some distress among the total football purists. Lets hope for the best.


Oh yeah, and the reason I have not posted for so long is that (as you obviously imagined...) I am very busy-- inter alia, have very impatient co-authors (they do have a point, though, and I have always liked challenges, hence all for the best this far)--, and have recently returned to Chicago from very interesting conferences in London (EALE-SOLE 2010; great organization by the UCL team of Richard, Steve & co) and in Skagen (Danish Microeconometric Network; admirably organized by Lars and Marianne). Following soon is SED at Montreal, with the greatest expectations. If I find the time, you'll read detailed criticisms and praises at some point.
