Of Pygmies and Auto Unions


I'm currently reading a book called Stumbling on Happiness, written by a Harvard psychology professor. It's a fascinating book that is part psychology, part philosophy, part cognitive neuroscience, part behavioural economics and all highly recommended. It aims to systematically and irrefutably answer the question, "Why do people so poorly imagine their ideal futures that they are rarely happy when they achieve them?"

To illustrate a piece of the puzzle, Gilbert relates an anecdote of a pygmy named Kenge who is led out of the dense, tropical forests of Africa by an anthropologist for the first time1. While out in the open plains, Kenge sees buffalo in the far distance as small, black specks and asks what they are. When told what they are he roars out in laughter telling the anthropologist not to tell him lies!

Having lived his entire life in a dense forest, Kenge had never learned that objects in the distance appear smaller and blurrier than objects that are close to us, something that we all take for granted.

The key leap that Gilbert then makes is that seeing in time is like seeing in space. When young couples are asked to describe getting married, those with a date in a few months use abstract, blurry phrases like "making a serious commitment" while those getting married the next day offer concrete details like "having pictures made" or "wearing a special outfit"2.

The key difference between spacial and temporal blurriness however, is that our minds are aware of the fact that the buffalo are blurry and ambiguous because they are far away, but they tend to believe that future events appear to be blurry and ambiguous because they are blurry and ambiguous. It explains why we frequently make future commitments that we dread fulfilling when the time comes.

Which leads us to the book While America Aged: How Pension Debts Ruined General Motors, Stopped the NYC Subways, Bankrupted San Diego, and Loom as the Next Financial Crisis. This book was discussed in January on NPR's Planet Money Podcast, in the context of the current automaker crisis. Their discussion struck me as a grand-scale illustration of Gilbert's concept of temporal blurriness that now threatens to destroy the entire industry.

Throughout the last few decades, the automakers have had to regularly meet with the unions to negotiate their collective bargaining agreement. And they have exhibited remarkably consistent behaviour in their bargaining, favouring larger, longer-term concessions versus smaller, short-term ones. For example when faced with a 3% wage raise and 50% salary pension pay-out, the automakers would instead counter with a 2.5% wage raise and a 75% salary pension pay-out.

The automakers were essentially acting as if future payment did not exist at all! They were almost literally trading a dollar today for a hundred dollars twenty years from now. And now, in this economic climate, the time has come for the automakers to fulfill their commitments - and they are dreading it...

A Pyramid Scheme Would Never Have Worked for Madoff

You've probably heard about the Bernard Madoff investment scandal, in which investors were fleeced of $50 billion. It has resulted in at least one investor committing suicide and just today Madoff agreed to submit a list of assets, liabilities and property to the SEC and we may finally have visibility to the extent of his fraud.

I've noticed that the press seems to use the term "Ponzi Scheme" and "Pyramid Scheme" interchangeably, though the two are different in concept.

According to wikipedia the differences are that:
  • In a Ponzi scheme, the schemer acts as a "hub" for the victims, interacting with all of them directly. In a multilevel scheme, those who recruit additional participants benefit directly (in fact, failure to recruit typically means no investment return).
  • A Ponzi scheme claims to rely on some esoteric investment approach, insider connections, etc., and often attracts well-to-do investors; multilevel schemes explicitly claim that new money will be the source of payout for the initial investments.
  • A multilevel scheme is bound to collapse a lot faster, due to the necessity of exponential increases in participants to sustain it. By contrast, Ponzi schemes can survive simply by persuading most existing participants to "reinvest" their money, with a relatively small number of new participants.
Based on these differences, we can see that a pyramid scheme would never have worked for Madoff:
  • By definition, hedge funds require an element of faith on the part of the investors since the hedge funds managers do not fully disclose the details of their investments - ostensibly it is the secret sauce that others could quickly duplicate and dilute the value of the opportunity. In other words, it's easy to setup a hedge fund, and the challenge lies in getting someone to invest in it. It was the respectable Bernie Madoff acting as the Ponzi scheme "hub" that lulled investors into a false sense of security
  • A pyramid scheme would have collapsed or been flagged by the authorities before reaching the size that the Madoff fund had attained. I'm willing to bet that a large portion of the $50 billion comes from initial investors who reinvested their money in the fund. Furthermore, institutional investors wouldn't touch an investment that is explicitly based on "new money."

Hello World!

Welcome to my blog and the first of what I hope to be many posts.

First thing that I'd like to do is to thank my sisters in law (or is it sister in laws?) - Katrina (http://www.katrinaschaman.com/) for designing the template for my blog and Jessika for (http://dimsumsimon.blogspot.com/) helping me overcome my initial inertia by starting her own blog over the Christmas break.

Recognizing that the Tubes are clogged with a multitude of inane rants and ramblings, my goals for this blog are:
  1. To serve as a forum for me to express my opinions. I believe that good opinions are an art form that can only be honed through practice. And while I don't imagine anyone will read this blog, I'm hoping that eventually this blog will engage me in discussions with people I wouldn't ordinarily meet.
  2. To help bring structure to the content that I find interesting on the Interwebs. In my day-to-day work as a management consultant, I have to deal with vast amounts of data and ambiguity and distill it to a set of clear and actionable recommendations. I'll bring a similar approach to help clear the FUD (fear, uncertainty and doubt) propagated throughout the Webernet
  3. To serve as a repository of thoughts and activities so that I can eventually retrospectively examine how my thoughts have evolved over time. Over time I'll also add my resume, links to Facebook, Twitter and Flickr, and eventually a podcast.
Signing off to work on my first post,
Irwin
