Traponomics

What in the world is “Traponomics?”

It is the ability to use game theory and incentives to trick guilty people into confessing.

I ran across an article in the Wall Street Journal on 9 May 2014 entitled, “How to Trick the Guilty and Gullible into Revealing Themselves”. Written by Steven Levitt and Stephen Dubner, the article talks about real life situations where the truth is reached through Machiavellian thinking. However, the authors postulate that it is actually done through game theory—the art of beating your opponent by anticipating their next move.

Machiavellian thinking in action

King Solomon identified the real mother of the baby by threatening to cut the child in half and giving each woman one half. One woman kept silent while the rightful mother told the king to give the child to the other woman. He knew the real mother would prefer to lose the baby rather than see it killed.

David Lee Roth, lead singer of Van Halen, wrote into their concert contracts that a bowl of M&M’s were to be provided but under no circumstance were there to be any brown M&M’s in the bowl. Was he a prima donna? At first you’d think so. But he wanted to make sure that the promoter read the entire contract (there were many safety issues included in the contract that needed the promoter’s attention). If Roth saw brown M&M’s in the bowl, he knew the promoter didn’t read it carefully enough. It was a way of identifying the guilty.

King Charles VI of France ruled for a long time. The problem was he was incapacitated by madness. During his periods of madness, his younger brother, Louis I (of Orléans) assumed command of the country. Louis was not well liked by the Parisians and others for many reasons. On the evening of 23 November 1407, Louis was viciously murdered by a mob of men. The murder of a royal family member, let alone the brother of the king, was an act that had far reaching implications. Read More Traponomics

“New York City, London, or Paris?”

unnamedHigh Priced Living

I’m reading a lot about the escalating prices of homes in London and how we common folk can’t afford to live in the city any longer. So a recent article in the Wall Street Journal (WSJ.com) caught my eye. It is entitled, Paris’s Haut Marais: From Shabby to Chic. It’s all about that too familiar story of a neighborhood that is run down, experiences high crime, and everyone stays away. But one day, several brave souls venture in, buy up some property, and begin to rejuvenate the neighborhood.

The Haut Marais (or Upper Marais) is essentially the part of the Marais District located in the 3e (third arrondissement or district). The southern portion of the Marais District is in the 4e and a common destination point for tourists. The article talks about apartment prices, the gentrification of the area, and some of dramatic improvements including several open air markets.

I decided to take a look at comparing some fundamental prices between New York City, London, and Paris. Here is data from April 2014 gathered by an online service known as Numbeo (all figures are in US$):

                                                                                      Paris               London           NYC

Meal for 2; mid-range restaurant:                        69.10              83.99              75.00

Domestic Beer:                                                            8.29                 6.05             6.00

Foreign Beer:                                                                6.91                 5.88             7.00

Milk (1 liter):                                                                1.51                 1.58             1.35

Eggs (dozen):                                                               4.33                 3.82             3.00

Bottle of Wine (mid-range):                                    8.29              11.76              15.00

Local Cheese (1kg):                                                  21.01              11.44              10.73

Gasoline (1 liter):                                                       2.26               2.34                 1.06

Basic Utilities:                                                           235.47          249.54              152.96

Cinema (one seat):                                                    13.82           20.16                 13.62

One pair of Nike shoes:                                            120               109                      89

Rent per Month (1 bedroom in the City):            1,578            2,470              2,857

Rent per Month (1 br. Out of the City):                 1,141             1,540              1,692

Price to Buy/Sq. Meter (in City):                           13,754          13,775              9,688

Now, its been a while since I’ve been in London or NYC but I can tell you (from first hand experience) that a beer in Paris is much more expensive than what Numbeo reports above. Another glaring exception is the local cheese. Sandy and I found that the least expensive food item when comparing to the US equivalents was cheese. We did notice on many occasions (regardless of where we went), shoe prices and specifically tennis shoes, were very expensive.

So what’s the lesson here?

Be it ever so humble, there’s no place like home.
