Le dernier rebond

Pourquoi le verre qui tombe se casse toujours sur le dernier rebond ? Parce qu’il arrête de rebondir une fois qu’il est cassé. Oui, c’est évident. Et pourtant… Voici une jolie étude pour montrer que le cours de bourse des actions suivantes n’a plus jamais atteint de record … depuis le dernier record qu’il a atteint !

Pragmatisme dans l’enseignement

Suite à une coupure budgétaire, un professeur de maths dont les sujets d’interrogation coûtent 500 $ par an en impression s’est vu demander de les imprimer pour 316 $… ce qu’il a réussi en vendant de la publicité sur les QCM !

Impact de la longueur de l’objet d’un mail

We did an analysis on all acquisition campaigns sent through our Postmaster Direct Network over the last two years. We found that response rate (as measured by clicks) goes down dramatically when the subject line is longer than 50 characters. How dramatic is this difference? Click-through rates for subject lines with 49 or fewer characters were 75 percent higher than for those with 50 or more.

Cela paraissait pourtant une bonne idée… en 2006.

[In] about five pages of lucid analysis, [Goldman Sachs] details the tectonic shifts shaping the world of finance. The key messages are that investment banks need to take more risks, commit more capital to their business, and start investing in the deals they recommend to their clients.

La justice au Zimbabwe

Victims of crime in Zimbabwe‘s capital city Harare are now allowed to ferry the alleged perpetrators of those crimes from prisons to court after the state prisons service ran out of fuel, according to local reports Thursday.

Conditions have improved significantly in Zimbabwe’s 42 jails since last year when an estimated 1,000 inmates had died in the first six months of the year of disease and neglect. But the Department of Prison Services still cannot provide transport to take prisoners awaiting trial to court.

Quoted – Bill Gates

“My tax return in the United States has to be kept on a special computer because their normal computers can’t deal with the numbers. So I am constantly getting these notices telling me I haven’t paid something when really it is just on the wrong computer. Then they will send me another notice telling me how bad they feel they that they sent me a notice that was a mistake.”

Le juste prix

Footnoted.org, déjà cité ici, permet parfois aussi de remarquer des exemples de bonne gouvernance.

Par exemple, Larry Ellison, le président d’Oracle, possède des sociétés liées qui fournissent divers biens et de services à la société. Dans ce cadre, il leur a conféré un accord écrit d’alignement sur le meilleur prix de marché, et de remboursement de la différence :

“…if we present Mr. Ellison with reasonable evidence of a lower price or rate for the same goods or services offered by the related company, which would have been available to us at the time we entered into the applicable transaction, then Mr. Ellison will reimburse us for the difference.”

Le financement allemand du cinéma américain

The Hollywood Sign as it appears from a trail ...
Image via Wikipedia

Peu de domaines sont aussi compliqués que le financement des long-métrages. La plupart du temps, cette complexité est liée à la maximisation des subventions et du levier fiscal qui augmentent les retours du producteurs sur les films qui réussissent.

En général cependant, toutes ces subventions et contreparties ont un prix : filmer dans un certain pays, dans certaines conditions, … Mais pas toujours, comme le montre le système des réductions d’impôt allemandes !

In 2003, German tax shelters, with the aid of German corporate shells and the happy cooperation of American studios, invested some $3 billion in the total fiction that they were owners, producers, and profit-sharers in Hollywood movies.

(…)

Consider the case of The Lord of the Rings: The Return of the King. A Munich-based tax-shelter fund, Hannover Leasing, had a corporate shell pay $150 million to New Line Cinemas for the movie’s copyright, which it simultaneously leased back to a New Line affiliate. It also entered into agreements for New Line to produce and distribute the movie. At the end of filming, New Line Cinemas paid the German company the agreed-upon minimum advance (which approximately equaled the interest on the initial investment) to honor the pretense that the Germans had participated in the profits. For engaging in these strictly paper transactions, New Line “earned” $16 million, a tidy “money-for-nothing” sum.

Trois économistes montent dans un taxi

Supposons que le passager A paierait, tout seul, un montant de 1 $. Le passager B, 5 $, et le passager C, 9$.  S’ils partagent un  taxi, la course totale est de 9 $.

Comment doivent-ils partager les 6 $ qu’ils ont collectivement économisés en partageant un seul taxi ?

La réponse, qui est beaucoup plus compliquée qu’il n’apparaît à première vue, est ici: Three Economists Get Into a Cab… – WSJ.com.

Sunset Fishing

Footnoted.com lit les publications annuelles des sociétés cotées et attire l’attention sur les informations – souvent croustillantes – remisées dans les notes de bas de page.

Celle-ci est particulièrement exceptionnelle :

During fiscal 2008, the Compensation Committee determined that maintaining a lease on a private airplane was no longer a cost-effective method for providing business-related transportation to our Named Executive Officers and Directors. The airplane was used only for business-related travel, and personal use was not permitted.

With the termination of the lease on the airplane, it also became increasingly difficult and cost prohibitive to access our Canadian fish camp. Consequently, the fish camp, which was only used for business entertainment purposes, was offered for sale during 2008.

The only offer to purchase the fish camp came from Terry L. Haines, our former Chief Executive Officer and President. Ultimately we negotiated with Mr. Haines to sell the fish camp for a purchase price of $55,000 and the transaction closed during fiscal year 2009.

L’auteur de The Invisible Hook – un (très bon) livre sur la justification économique de l’organisation adoptée par les bateaux pirates – profite de sa préface pour discrètement faire sa demande en mariage :

I can’t thank her enough and, as with everything, I don’t know where I’d be without her. In this book’s dedication I ask her to marry me. If I’ve succeeded in hiding my plans from her since writing this, she should be very surprised. I hope she says “yes.” If she doesn’t, I might have to turn to sea banditry, which would be tough since I don’t know how to sail (though I’ve tried to learn)

Coller warns of private equity ‘scandal’ and calls for greater transparency

Déjà en 2005 …

The result of the opacity of performance data across the industry was a persistence of mediocrity, [Jeremy Coller] said. ‘The private nature of private equity has allowed too much poor performance to be hidden by smoke and mirrors,’ Coller said.

He proposed four steps that fund managers should make compulsory to improve governance; a requirement for all funds to be audited by one of the big four accounting firms, the use of custodians by PE firms, no-fault divorce clauses in all limited partners agreements, and the complete abolition of deal by deal carry.

Vladimir K. Zworykin's patent 1923
Image via Wikipedia

Il y a des millions de choses qui ne tournent pas rond dans le système américain des brevets, mais la plupart de ces choses sont liées à l’effet que ces brevets ont sur l’économie.

Il apparaît (article de Ezra Klein, repris par Marginal Revolution) que les problèmes sont aussi dans leur informatique interne :

Orszag quotes the president bragging that “the Patent Office receives more than 80 percent of patent applications electronically,” but notes that “these applications are then manually printed out, re-scanned, and entered into an outdated case management system. The average processing time for a patent is roughly three years.”

Durée médiane du chômage

Alors qu’il devient de plus en plus clair que l’information sur le nombre de chômeurs n’est, en soi, pas suffisante pour estimer l’ampleur du phénomène, on entend de plus en plus souvent citer le nombre de chômeurs de longue durée.

Cependant, si cet indicateur est déjà meilleur, Greg Mankiw analyse sur son blog un autre axe : la durée médiane du chômage aux Etats-Unis. Cette durée est significative, parce que par définition, 50 % des chômeurs sont aux chômage depuis au moins aussi longtemps.

La courbe est assez inquiétante, atteignant des durées jamais vues dans un passé récent :

Durée médiane du chômage en augmentation forte
