Why Your Boss Is Overpaid

It is a typical "Dilbert" strip. The boss announces, "Our CEO has voluntarily slashed his pay from $6 million per year to $4 million. In a written statement, he said he wants to 'share the pain.' Do you feel better now?" A downtrodden intern replies, "I make my underpants from sandwich bags."

But that's office life, is it not? Bosses make obscene sums of money, while downtrodden cubicle slaves toil almost without reward. It might seem insane, but economists have a surprise for us: The insanity reflects nothing more than cool economic logic. There is method in the madness.

The ugly truth is that your boss is probably overpaid--and it's for your benefit, not his. Why? It might be because he isn't being paid for the work he does but, rather, to inspire you. In other words, we work our socks off in underpaying jobs in the hope that one day we'll win the rat race and become overpaid fat cats ourselves. Economists call this "tournament theory."

After all, managers find it hard to spot an excellent performance. It is a rare job where workers can be fairly paid according to some objective criteria.

There are some exceptions, of course. Critics and audiences may disagree about the literary merits of Dan Brown's best seller, The Da Vinci Code. Yet from a business point of view, the success is easy to measure. He has sold about 40 million books and is rewarded with a payment for each one.

Another superstar, tennis champion Roger Federer, has qualities that cannot be so easily calibrated. So instead of trying to measure his performance in objective terms, as Dan Brown's is measured, we measure it in relative terms. If Federer beats Andy Roddick in the final of the U.S. Open, he has succeeded.

Federer is not paid to try hard, nor to produce objectively brilliant tennis. He is paid for beating other players. Yet that is enough to get the best out of him. It is likely that employers have long since noticed that paying for relative performance can be just as good as trying to pay for absolute performance.

The economists Edward Lazear (recently appointed to chair the Council of Economic Advisors) and the late Sherwin Rosen argued, in a hugely influential paper published 25 years ago, that tournaments are an integral and often invisible part of the workplace. Workers are frequently ranked relative to each other and promoted not for being good at their jobs but for being better than their rivals. It is a natural response to the difficulty of true performance pay.

Tournaments also help protect workers against risks they cannot control. Companies can be affected by recessions, unexpected competition and hurricanes. As long as every worker is equally affected, the incentives to try hard remain the same. Trying to encourage performance through, say, stock options would unnecessarily expose workers to risks without really encouraging them to work harder.

Promotion tournaments sound sensible: Good workers are promoted, less capable workers are not. Yet the widespread use of tournaments also goes a long way toward explaining the frustrations of office life.

First, one way for you to win is for your colleagues to lose. Companies that rely too heavily on competition to determine promotions may find that their employees discover that the most efficient way of winning a promotion is by sabotaging the efforts of their rivals. You don't need economic theory to spot that risk.

The second, and more counterintuitive, prediction of tournament theory is that the more luck is involved in work, the larger the pay gaps should be between the winners and the losers. If Jack's promotion is 90% luck and 10% effort, Jack may be inclined to goof off--unless, of course, the rewards for promotion are absolutely astronomical. And they sometimes are.

Tournaments also demand increasingly absurd pay packages as workers get higher up the hierarchy. At the lowest level, a promotion may not need to carry much of a pay increase, because it opens up the possibility of future, lucrative promotions. Nearer the end of your career, only a fat check is likely to spur you on.

Finally, tournament theory also helps to explain why insiders, not outsiders, get cushy jobs. You thought it was all about the old-boy network, but in fact, the logical reason for promoting insiders is clear: These jobs are designed to keep your workforce motivated.

Lazear and Rozen's tournament theory has stood the test of time and been supported by many subsequent pieces of empirical research. It also passes the smell test: The more grotesque your boss's pay and the less he has to do to earn it, the bigger the motivation for you to work for a promotion. As Lazear wrote in his book, Personnel Economics for Managers, "The salary of the vice president acts not so much as motivation for the vice president as it does as motivation for the assistant vice presidents."

Economists don't even pretend that your boss deserves his salary. Suddenly, everything is clear.

Alien Lifeform .... Is there any ???

As NASA prepares to hunt for Earth-like planets in our corner of the Milky Way galaxy, there's new buzz that "Star Trek's" vision of a universe full of life may not be that far-fetched.

An artist's impression shows a planet passing in front of its parent star. Such events are called transits.

Pointy-eared aliens traveling at light speed are staying firmly in science fiction, but scientists are offering fresh insights into the possible existence of inhabited worlds and intelligent civilizations in space.

There may be 100 billion Earth-like planets in the Milky Way, or one for every sun-type star in the galaxy, said Alan Boss, an astronomer with the Carnegie Institution and author of the new book "The Crowded Universe: The Search for Living Planets."

He made the prediction based on the number of "super-Earths" -- planets several times the mass of the Earth, but smaller than gas giants like Jupiter -- discovered so far circling stars outside the solar system.

Boss said that if any of the billions of Earth-like worlds he believes exist in the Milky Way have liquid water, they are likely to be home to some type of life.

"Now that's not saying that they're all going to be crawling with intelligent human beings or even dinosaurs," he said.

"But I would suspect that the great majority of them at least will have some sort of primitive life, like bacteria or some of the multicellular creatures that populated our Earth for the first 3 billion years of its existence."

Hunt for habitable planets

NASA is hoping to find much more habitable worlds with the help of the upcoming Kepler mission. The spacecraft, set to be launched from Cape Canaveral Air Force Station in Florida next week, will search for Earth-size planets in our part of the galaxy.

Kepler contains a special telescope that will study 100,000 stars in the Cygnus-Lyra region of the Milky Way for more than three years. It will look for small dips in a star's brightness, which can mean an orbiting planet is passing in front of it -- an event called a transit.

"It's akin to measuring a flea as it creeps across the headlight of an automobile at night," said Kepler project manager James Fanson during a during a NASA news conference.

The focus of the mission is finding planets in a star's habitable zone, an orbit that would ensure temperatures in which life could exist.

Boss, who serves on the Kepler Science Council, said scientists should know by 2013 -- the end of Kepler's mission -- whether life in the universe could be widespread.

Finding intelligent life is a very different matter. For all the speculation about the possibility of other civilizations in the universe, the question remains: If the rise of life on Earth isn't unique and aliens are common, why haven't they shown up or contacted us? The contradiction was famously summed up by the physicist Enrico Fermi in 1950 in what became known as the Fermi paradox: "Where is everybody?"

The answer may be the vastness of time and space, scientists explained.

"Civilizations come and go," Boss said. "Chances are, if you do happen to find a planet which is going to have intelligent life, it's not going to be in [the same] phase of us. It may have formed a billion years ago, or maybe it's not going to form for another billion years."

Even if intelligent civilizations did exist at the same time, they probably would be be separated by tens of thousands of light years, Forgan said. If aliens have just switched on their transmitter to communicate, it could take us hundreds of centuries to receive their message, he added.

World Disorder in terms of clock

This is a very interesting site stating the statistics on different on-goings in the world. I don't know the statistics algorithm but seems interesting though.

http://www.poodwaddle.com/worldclock.swf

I have only one concern. Why people are more interested in measuring the disorder than the order, misery than happiness, evil than good????? We do have a strange perspective and yet we crave for happiness and peace.

Look at the photographs :)

A Must watch site. Its basically flash based but one of the best works Ive seen. More over the camera work done is exceptional if not the best. 3 cheers for the designers and cameramen.

A Black Hole Record

In athletic events such as swimming or running, a world record will often stand for several years before it’s broken. The same thing usually holds true for astronomical records as well.


In this artist’s portrayal of the IC 10 X-1 system, the black hole lies at the upper left and its companion star is on the right. The two objects orbit around a center of gravity once every 34.4 hours. The stellar companion is a type known as a Wolf-Rayet star. Such stars are highly evolved and destined to explode as supernovae. The black hole companion is shedding its outer envelope in a powerful wind, and some of this gas is captured by the black hole’s powerful gravity.

On October 17, 2007, astronomers using NASA’s Chandra X-ray Observatory announced that a black hole in the galaxy M33 contains 16 times the mass of the Sun. For two weeks it was the heaviest known black hole of its type. Such black holes are known as "stellar-mass" black holes, because they have masses typical of stars.

SN 2006gy - Brightest Ever Recorded Super nova

The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes. This discovery indicates that violent explosions of extremely massive stars were relatively common in the early universe, and that a similar explosion may be ready to go off in our own galaxy.



The top panel of this graphic is an artist's illustration that shows what SN 2006gy may have looked like if viewed at a close distance. The bottom left panel is an infrared image, using adaptive optics at the Lick Observatory, of NGC 1260, the galaxy containing SN 2006gy. The panel to the right shows Chandra's X-ray image of the same field of view, again showing the nucleus of NGC 1260 and SN 2006gy.

"This was a truly monstrous explosion, a hundred times more energetic than a typical supernova," said Nathan Smith of the University of California at Berkeley, who led a team of astronomers from California and the University of Texas in Austin. "That means the star that exploded might have been as massive as a star can get, about 150 times that of our sun. We've never seen that before."
Astronomers think many of the first generation of stars were this massive, and this new supernova may thus provide a rare glimpse of how the first stars died. It is unprecedented, however, to find such a massive star and witness its death. The discovery of the supernova, known as SN 2006gy, provides evidence that the death of such massive stars is fundamentally different from theoretical predictions.

"Of all exploding stars ever observed, this was the king," said Alex Filippenko, leader of the ground-based observations at the Lick Observatory at Mt. Hamilton, Calif., and the Keck Observatory in Mauna Kea, Hawaii. "We were astonished to see how bright it got, and how long it lasted."

The Chandra observation allowed the team to rule out the most likely alternative explanation for the supernova: that a white dwarf star with a mass only slightly higher than the sun exploded into a dense, hydrogen-rich environment. In that event, SN 2006gy should have been 1,000 times brighter in X-rays than what Chandra detected.

"This provides strong evidence that SN 2006gy was, in fact, the death of an extremely massive star," said Dave Pooley of the University of California at Berkeley, who led the Chandra observations.

The star that produced SN 2006gy apparently expelled a large amount of mass prior to exploding. This large mass loss is similar to that seen from Eta Carinae, a massive star in our galaxy, raising suspicion that Eta Carinae may be poised to explode as a supernova. Although SN 2006gy is intrinsically the brightest supernova ever, it is in the galaxy NGC 1260, some 240 million light years away. However, Eta Carinae is only about 7,500 light years away in our own Milky Way galaxy.

"We don't know for sure if Eta Carinae will explode soon, but we had better keep a close eye on it just in case," said Mario Livio of the Space Telescope Science Institute in Baltimore, who was not involved in the research. "Eta Carinae's explosion could be the best star-show in the history of modern civilization."

Supernovas usually occur when massive stars exhaust their fuel and collapse under their own gravity. In the case of SN 2006gy, astronomers think that a very different effect may have triggered the explosion. Under some conditions, the core of a massive star produces so much gamma ray radiation that some of the energy from the radiation converts into particle and anti-particle pairs. The resulting drop in energy causes the star to collapse under its own huge gravity.

After this violent collapse, runaway thermonuclear reactions ensue and the star explodes, spewing the remains into space. The SN 2006gy data suggest that spectacular supernovas from the first stars - rather than completely collapsing to a black hole as theorized - may be more common than previously believed.

"In terms of the effect on the early universe, there's a huge difference between these two possibilities," said Smith. "One pollutes the galaxy with large quantities of newly made elements and the other locks them up forever in a black hole."

World's Largest Swimming Pool

If you like doing laps in the swimming pool, you might want to stock up on the energy drinks before diving in to this one.

It is more than 1,000 yards long, covers 20 acres, had a 115ft deep end and holds 66 million gallons of water.

Yesterday the Guinness Book of Records named the vast pool beside the sea in Chile as the biggest in the world.





But if you fancy splashing out on one of your own – and you have the space to accommodate it – then beware: This one took five years to build, cost nearly £1billion and the annual maintenance bill will be £2million.

The man-made saltwater lagoon has been attracting huge crowds to the San Alfonso del Mar resort at Algarrobo, on Chile's southern coast, since it opened last month.

Its turquoise waters are so crystal clear that you can see the bottom even in the deep end.

It dwarfs the world's second biggest pool, the Orthlieb – nicknamed the Big Splash – in Morocco, which is a mere 150 yards long and 100 yards wide. An Olympicsize pool measures some 50 yards by 25 yards.






Chile's monster pool uses a computer- controlled suction and filtration system to keep fresh seawater in permanent circulation, drawing it in from the ocean at one end and pumping it out at the other.

The sun warms the water to 26c, nine degrees warmer than the adjoining sea.

Chilean biochemist Fernando Fischmann, whose Crystal Lagoons Corporation designed the pool, said advanced engineering meant his company could build "an impressive artificial paradise" even in inhospitable areas.

"As long as we have access to unlimited seawater, we can make it work, and it causes no damage to the ocean."

Children play in the clear waters of the 3,323 ft long pool


The saltwater pool contains 250,000 cubic metres of water and is navigable in small boats

Microsoft Surface Computer




A Surface computer is able to recognize physical objects from a paintbrush to a cell phone and allows hands-on, direct control of content such as photos, music and maps. Surface turns an ordinary tabletop into a dynamic surface that provides interaction with all forms of digital content through natural gestures, touch and physical objects.

The new product is aimed directly at hotels, retail establishments, restaurants and public entertainment venues and should be commercially available towards the end of the year.

It’s an interesting product in that it’s completely out of left field. Microsoft gives examples of ordering a beverage during a meal with just the tap of a finger and quickly browsing through music and dragging favorite songs onto a personal playlist by moving a finger across the screen. Build this into a bar and you’d get one-touch beer service although I’m not sure if they’ve found a way to work out when your beer glass is empty so replenishment becomes automatic, maybe in a later version.

The practical uses for Surface at the point of sale are broad. This is touch screen point of sale technology at a new level.

Initial launch partners include Harrah’s Entertainment, Starwood Hotels and T-Mobile.
