The Big Mac Index

The Economist has updated their Big Mac Index, a “fun” measure of how purchasing power varies from country to country.

It is based on the theory of purchasing-power parity (PPP), the notion that in the long run exchange rates should move towards the rate that would equalise the prices of a basket of goods and services around the world. At market exchange rates, a burger is 44% cheaper in China than in America. In other words, the raw Big Mac index suggests that the yuan is 44% undervalued against the dollar. But we have long warned that cheap burgers in China do not prove that the yuan is massively undervalued. Average prices should be lower in poor countries than in rich ones because labour costs are lower. The chart above shows a strong positive relationship between the dollar price of a Big Mac and GDP per person.


The economics of penis size

A paper authored by Tatu Westling of Helsinki University explores the relationship between the GDP growth of countries and the penile length of their residents.

The size of male organ is found to have an inverse U-shaped relationship with the level of GDP in 1985. It can alone explain over 15% of the variation in GDP. The GDP maximizing size is around 13.5 centimetres, and a collapse in economic development is identified as the size of male organ exceeds 16 centimetres.

That “U-shaped” curve…it looks like something flaccid-ish, innit? (via @atenni)


The economics of an ice cream cone

At a Boston ice cream shop, the cost of ice cream cone has risen 10% in the last four months. The Boston Globe investigated down the supply chain and detailed where the price increases are coming from.

Ice cream may be a deliciously simple combination of milk, butter, and sugar, but the true cost of an ice cream cone is no simple business calculation. Toscanini’s price tag is part of complex and increasingly interconnected world economy, one that links a dairy farm in the tiny Western Massachusetts town of Colrain to the sprawling neighborhoods of Beijing.

Also of note: pistachio ice cream might be difficult to find this summer because the cost of pistachios has increased sharply in recent months. (via girlhacker)


The Groupon IPO

I don’t really have an opinion about it, but David Heinemeier Hansson does:

Groupon has filed its S-1 and hopes to raise $750M in its initial public offering. Given they’re currently losing a staggering $117M per quarter, despite revenues of $644M, they’ll be burning through that cash almost as soon as it hits their account.

At the moment, it’s costing them $1.43 to make $1, and it doesn’t look like it’s getting any cheaper. They’re already projected to make close to three billion dollars in revenues this year. If you can’t figure out how to make money on three billion in revenue, when exactly will the profit magic be found? Ten billion? Fifty billion?

To which John Gruber adds:

I feel like the Groupon IPO is an elaborate practical joke.

It was a different time and (as DHH notes) a different company, but when Amazon IPOed in 1997, they lost $27.6 million that year on net sales of $147.8 million. That’s an 18% loss for Amazon compared to Groupon’s, hey, 18% loss. Amazon didn’t report their first profit until Q4 2001. No guarantee whether Groupon will ever turn a profit but something to consider anyway. Oh, and probably not relevant but interesting nonetheless: Amazon CEO Jeff Bezos is an investor in DHH’s company, 37signals…and until recently, 37signals co-founder Jason Fried was on Groupon’s board of directors.


Why the crime decline?

Nice summary of the current thinking about why crime is falling in the US even though the unemployment rate is relatively high. One possible culprit is leaded gasoline:

There may also be a medical reason for the decline in crime. For decades, doctors have known that children with lots of lead in their blood are much more likely to be aggressive, violent and delinquent. In 1974, the Environmental Protection Agency required oil companies to stop putting lead in gasoline. At the same time, lead in paint was banned for any new home (though old buildings still have lead paint, which children can absorb).

Tests have shown that the amount of lead in Americans’ blood fell by four-fifths between 1975 and 1991. A 2007 study by the economist Jessica Wolpaw Reyes contended that the reduction in gasoline lead produced more than half of the decline in violent crime during the 1990s in the U.S. and might bring about greater declines in the future. Another economist, Rick Nevin, has made the same argument for other nations.

NYC groceries cheaper than in rest of the US

It seems that item for item, food in New York City is actually cheaper than in many other parts of the country.

Using data from the ACNielsen HomeScan database, which employed bar-code scanners to track every purchase made by roughly 33,000 U.S. households in 2005, the two economists compared identical products sold in cities big and small, both at high-end grocery stores and discount retailers. In nearly every case, New York products were cheaper than in places such as Memphis, Indianapolis and Milwaukee.

A Disneyland of child labor

The Morning News has a piece today on KidZania, a theme park for kids where they work and buy stuff just like grown-ups.

But at the heart of the concept and the business of KidZania is corporate consumerism, re-staged for children whose parents pay for them to act the role of the mature consumer and employee. The rights to brand and help create activities at each franchise are sold off to real corporations, while KidZania’s own marketing emphasizes the arguable educational benefits of the park.

Kidzania

Each child receives a bank account, an ATM card, a wallet, and a check for 50 KidZos (the park’s currency). At the park’s bank, which is staffed by adult tellers, kids can withdraw or deposit money they’ve earned through completing activities โ€” and the account remains even when they go home at the end of the day. A lot of effort goes into making the children repeat visitors of this Lilliputian city-state.

A US outpost of KidZania is coming sometime in 2013.


How a Tokyo Earthquake Could Devastate Wall Street and the Global Economy

That’s the title of an article written by Michael Lewis in 1989.

A big quake has hit Tokyo roughly every 70 years for four centuries: 1923, 1853, 1782, 1703, 1633.

Pay the homeless

If a small experiment conducted in London is any indication, a cost effective way to help the homeless may be to simply give them money.

One asked for a new pair of trainers and a television; another for a caravan on a travellers’ site in Suffolk, which was duly bought for him. Of the 13 people who engaged with the scheme, 11 have moved off the streets. The outlay averaged ยฃ794 ($1,277) per person (on top of the project’s staff costs). None wanted their money spent on drink, drugs or bets. Several said they co-operated because they were offered control over their lives rather than being “bullied” into hostels. Howard Sinclair of Broadway explains: “We just said, ‘It’s your life and up to you to do what you want with it, but we are here to help if you want.’”

ยฃ794 per person may sound high but not compared to the estimated ยฃ26,000 annually spent on each homeless person by the state.


The Celtic Paper Tiger

Michael Lewis continues his tour of economic disasters โ€” he wrote about Greece and Iceland for Vanity Fair and wrote an entire book on the US subprime mess โ€” with a piece on Ireland and the country’s spectacular rise in becoming Europe’s mightiest economic engine and even steeper fall to third-world economic mess.

Even in an era when capitalists went out of their way to destroy capitalism, the Irish bankers set some kind of record for destruction. Theo Phanos, a London hedge-fund manager with interests in Ireland, says that “Anglo Irish was probably the world’s worst bank. Even worse than the Icelandic banks.”

Ireland’s financial disaster shared some things with Iceland’s. It was created by the sort of men who ignore their wives’ suggestions that maybe they should stop and ask for directions, for instance. But while Icelandic males used foreign money to conquer foreign places โ€” trophy companies in Britain, chunks of Scandinavia โ€” the Irish male used foreign money to conquer Ireland. Left alone in a dark room with a pile of money, the Irish decided what they really wanted to do with it was to buy Ireland. From one another. An Irish economist named Morgan Kelly, whose estimates of Irish bank losses have been the most prescient, made a back-of-the-envelope calculation that puts the losses of all Irish banks at roughly 106 billion euros. (Think $10 trillion.) At the rate money currently flows into the Irish treasury, Irish bank losses alone would absorb every penny of Irish taxes for at least the next three years.

In recognition of the spectacular losses, the entire Irish economy has almost dutifully collapsed. When you fly into Dublin you are traveling, for the first time in 15 years, against the traffic. The Irish are once again leaving Ireland, along with hordes of migrant workers. In late 2006, the unemployment rate stood at a bit more than 4 percent; now it’s 14 percent and climbing toward rates not experienced since the mid-1980s. Just a few years ago, Ireland was able to borrow money more cheaply than Germany; now, if it can borrow at all, it will be charged interest rates nearly 6 percent higher than Germany, another echo of a distant past. The Irish budget deficit โ€” which three years ago was a surplus โ€” is now 32 percent of its G.D.P., the highest by far in the history of the Eurozone. One credit-analysis firm has judged Ireland the third-most-likely country to default. Not quite as risky for the global investor as Venezuela, but riskier than Iraq. Distinctly Third World, in any case.


LCD Soundsystem ticket debacle

So, LCD Soundsystem is retiring and to see off their fans, they decided to perform one last show at Madison Square Garden. Except that they didn’t think they’d sell the place out and didn’t pay too much attention to how the tickets were being sold. When the tickets went on sale last week, they sold out immediately. Many fans didn’t get tickets, the band’s family and friends didn’t get tickets, and even some of the band didn’t get tickets. Scalpers bought thousands upon thousands of tickets and the band is hopping mad. So they’re adding four more NYC shows right before the MSG gig to give their fans a chance to see them and to screw the scalpers by increasing the supply (and therefore lowering demand and prices).

oh-and a small thing to scalpers: “it’s legal” is what people say when they don’t have ethics. the law is there to set the limit of what is punishable (aka where the state needs to intervene) but we are supposed to have ethics, and that should be the primary guiding force in our actions, you fucking fuck.

It would be fun if all those scalpers got stuck with thousands of unsellable MSG tickets.


Picturing economic inequality

Dutch economist Jan Pen devised a clever way of picturing economic inequality: as the height of people walking past you.

Imagine people’s height being proportional to their income, so that someone with an average income is of average height. Now imagine that the entire adult population of America is walking past you in a single hour, in ascending order of income.

The first passers-by, the owners of loss-making businesses, are invisible: their heads are below ground. Then come the jobless and the working poor, who are midgets. After half an hour the strollers are still only waist-high, since America’s median income is only half the mean. It takes nearly 45 minutes before normal-sized people appear. But then, in the final minutes, giants thunder by. With six minutes to go they are 12 feet tall. When the 400 highest earners walk by, right at the end, each is more than two miles tall.

The economics of Seinfeld

Dozens of scenes from Seinfeld used to explain economic concepts. For instance, in an episode from season five:

George thinks he has been offered a job, but the man offering it to him got interrupted in the middle of the offer, and will be on vacation for the next week. George, unsure whether an offer has actually been extended, decides that his best strategy is to show up. If the job was indeed his, this is the right move. But even if the job is not, he believes that the benefits outweigh the costs.

Economic concepts touched on: cost-benefit analysis, dominant strategy, and game theory. (via what i learned today)


Complexity and the fall of Rome

In Jospeh Tainter’s The Collapse of Complex Societies, the author argues that the fall of Rome happened because “the usual method of dealing with social problems by increasing the complexity of society [became] too costly or beyond the ability of that society”. Basically when Rome stopped expanding its territory, the fallback was relying solely on agriculture, a relatively low-margin affair.

The distances, now no longer adjacent to easily accessible coastline, were making the cost of conquest prohibitive. More to the point, the enemies Rome faced as it grew larger were vast empires themselves and were more than capable of defeating the Roman legions.

It was at this point that Rome had reached a turning point: no longer would conquest be a significant source of revenue for the empire, for the cost of further expansion yielded no benefits greater than incurred costs. Conjointly, garrisoning its extensive border with its professional army was becoming more burdensome, and more and more Rome came to rely on mercenary troops from Iberia and Germania.

The result of these factors meant that the Roman Empire began to experience severe fiscal problems as it tried to maintain a level of social complexity that was beyond the marginal yields of it’s agricultural surplus and had been dependent upon continuous territorial expansion and conquest.

Hopefully I don’t have to draw you a picture of how this relates to large bureaucratic companies.


Inflationary language

Comedian and entertainer Victor Borge used to do a bit where he’d muse about the application of economic inflation to language.

See, we have hidden numbers in the words like “wonderful,” “before,” “create,” “tenderly.” All these numbers can be inflated and meet the economy, you know, by rising to the occcassion. I suggest we add one to each of these numbers to be prepared. For example “wonderful” would be “two-derful.” Before would be Be-five. Create, cre-nine. Tenderly should be eleven-derly. A Leiutenant would be a Leiut-eleven-ant. A sentance like, “I ate a tenderloin with my fork” would be “I nine an elevenderloin with my five-k.”

Here’s the whole routine:

Building a Black Swan-robust society

New Statesman has an excerpt of the new-for-the-paperback postscript from Nassim Taleb’s The Black Swan, which book was probably the most interesting one I’ve read in quite some time (if you can handle some of the ridiculous posturing).

An economist would find it inefficient to carry two lungs and two kidneys โ€” consider the costs involved in transporting these heavy items across the savannah. Such optimisation would, eventually, kill you, after the first accident, the first “outlier”. Also, consider that if we gave Mother Nature to economists, it would dispense with individual kidneys โ€” since we do not need them all the time, it would be more “efficient” if we sold ours and used a central kidney on a time-share basis. You could also lend your eyes at night, since you do not need them to dream.

Read through to the end for Taleb’s list of ten principles for a Black Swan-robust society.


800 years of financial folly

Unsurprisingly finding itself on the bestseller list is a book by Kenneth Rogoff and Carmen Reinhart called This Time is Different, an economic history of the dozens of financial crises that have occurred over the past 800 years. The NY Times has a profile of the authors.

Mr. Rogoff says a senior official in the Japanese finance ministry was offended at the suggestion in “This Time Is Different” that Japan had once defaulted on its debt and sent him an angry letter demanding a retraction. Mr. Rogoff sent him a 1942 front-page article in The Times documenting the forgotten default. “Thank you,” the official wrote in apology, “for teaching the Japanese something about our own country.”


Social status and nightclub bouncers

A professor from the Kellogg School of Management wondered: what rules do the bouncers at exclusive night clubs use to filter some clientele into the club and leave others out in the cold?

Bouncers weighed each cue differently. Social network mattered most, gender followed. For example, a young woman in jeans stood a higher chance of entrance than a well-dressed man. And an elegantly dressed black man stood little chance of getting in unless he knew someone special.


Dear Leader meets Sim City

A 22-yo architecture student from The Philippines has “beaten” Sim City 3000 by building a city with the largest possible population that sustains itself for 50,000 years. The city, called Magnasanti, is not somewhere you would want to live.

There are a lot of other problems in the city hidden under the illusion of order and greatness: Suffocating air pollution, high unemployment, no fire stations, schools, or hospitals, a regimented lifestyle โ€” this is the price that these sims pay for living in the city with the highest population. It’s a sick and twisted goal to strive towards. The ironic thing about it is the sims in Magnasanti tolerate it. They don’t rebel, or cause revolutions and social chaos. No one considers challenging the system by physical means since a hyper-efficient police state keeps them in line. They have all been successfully dumbed down, sickened with poor health, enslaved and mind-controlled just enough to keep this system going for thousands of years. 50,000 years to be exact. They are all imprisoned in space and time.

Update: In 1922, Le Corbusier designed an “ideal” city with 3 million inhabitants. (thx, diana)


Taming Manhattan’s traffic

In an attempt to eliminate Manhattan’s travel inefficiencies and encourage more use of public transportation, Charles Komanoff spent three years creating an Excel spreadsheet (you can download it here) that details “the economic and environmental impact of every single car, bus, truck, taxi, train, subway, bicycle, and pedestrian moving around New York City”. Based on that research, he’s come up with a plan for changing how transportation is paid for in Manhattan below 60th St. (the CBD or central business district).

It would charge $3 to cars entering the CBD on weekday nights, $6 for most of the day, and $9 during rush hour. The subway fare also varies, but is always less than the $2.25 it is today: $1 at night, rising to $1.50 as day breaks, and peaking at $2 during weekday rush hours. Buses are always free, because the time saved when passengers aren’t fumbling for change more than makes up for the lost fare revenue. Komanoff’s plan also imposes a 33 percent surcharge on every taxi ride, 10 percent of which would go to the cab driver and the rest to the city.

Komanoff’s plan is vastly more sophisticated than a simple bridge toll. Instead of merely punishing drivers, he has built a delicate system of incentives and revenue streams. Just as a musical fugue weaves several melodic lines into a complex yet harmonious whole, Komanoff’s policy assembles all the various modes of transportation into a coherent, integrated traffic system.


Restaurant chain opens pay what you can cafe

Panera Bread Co converted one of their St. Louis locations into a cafe without prices. I love this model, but I feel like it probably works better with one of a kind products (art, music, movies, books) that are likely to have passionate fans. I hope it works, though. Ron Shaich Panera’s chairman had this to say:

I’m trying to find out what human nature is all about. My hope is that we can eventually do this in every community where there’s a Panera.

The neuroscience of Costco

Jonah Lehrer on what our brains are up to when we’re shopping at Costco.

As I note in How We Decide, this data directly contradicts the rational models of microeconomics. Consumers aren’t always driven by careful considerations of price and expected utility. We don’t look at the electric grill or box of chocolates and perform an explicit cost-benefit analysis. Instead, we outsource much of this calculation to our emotional brain, and rely on relative amounts of pleasure versus pain to tell us what to purchase.


My First Toxic Asset

The Planet Money podcast bought a toxic asset and is tracking what happens to the 2000+ mortgages that are bundled up into it over time.

We bought one of those things that no one wanted, one of those things that almost brought down the global economy: our very own toxic asset. This one has more than 2,000 mortgages in it. We paid $1,000, with our own money, for our piece. It used to be worth more like $75,000. Click on the timeline and roll over the states to watch a disaster in progress.

Somewhat of a surprise: they’ve made more than a third of their money back already.


The economics of the mushy middle

Companies who target the middle of the market (Sony, Dell, General Motors) are losing customers to companies like Apple & Hermes at the high end and Ikea & H&M at the low end. From James Surowiecki:

The products made by midrange companies are neither exceptional enough to justify premium prices nor cheap enough to win over value-conscious consumers. Furthermore, the squeeze is getting tighter every day. Thanks to economies of scale, products that start out mediocre often get better without getting much more expensive โ€” the newest Flip, for instance, shoots in high-def and has four times as much memory as the original โ€” so consumers can trade down without a significant drop in quality. Conversely, economies of scale also allow makers of high-end products to reduce prices without skimping on quality. A top-of-the-line iPod now features video and four times as much storage as it did six years ago, but costs a hundred and fifty dollars less. At the same time, the global market has become so huge that you can occupy a high-end niche and still sell a lot of units. Apple has just 2.2 per cent of the world cell-phone market, but that means it sold twenty-five million iPhones last year.


Warren Buffett’s 2009 annual letter to shareholders

Worth a read as always.

We will never become dependent on the kindness of strangers. Too-big-to-fail is not a fallback position at Berkshire. Instead, we will always arrange our affairs so that any requirements for cash we may conceivably have will be dwarfed by our own liquidity. Moreover, that liquidity will be constantly refreshed by a gusher of earnings from our many and diverse businesses.

When the financial system went into cardiac arrest in September 2008, Berkshire was a supplier of liquidity and capital to the system, not a supplicant. At the very peak of the crisis, we poured $15.5 billion into a business world that could otherwise look only to the federal government for help. Of that, $9 billion went to bolster capital at three highly-regarded and previously-secure American businesses that needed โ€” without delay โ€” our tangible vote of confidence. The remaining $6.5 billion satisfied our commitment to help fund the purchase of Wrigley, a deal that was completed without pause while, elsewhere, panic reigned.

We pay a steep price to maintain our premier financial strength. The $20 billion-plus of cash-equivalent assets that we customarily hold is earning a pittance at present. But we sleep well.

Here’s to sleeping well.


Paul Krugman profile

The New Yorker has a nice profile of Paul Krugman in this week’s magazine. His political awakening has a somewhat born-again Christian vibe to it.

In his columns, Krugman is belligerently, obsessively political, but this aspect of his personality is actually a recent development. His parents were New Deal liberals, but they weren’t especially interested in politics. In his academic work, Krugman focussed mostly on subjects with little political salience. During the eighties, he thought that supply-side economics was stupid, but he didn’t think that much about it. Unlike Wells, who was so upset when Reagan was elected that she moved to England, Krugman found Reagan comical rather than evil. “I had very little sense of what was at stake in the tax issues,” he says. “I was into career-building at that point and not that concerned.” He worked for Reagan on the staff of the Council of Economic Advisers for a year, but even that didn’t get him thinking about politics. “I feel now like I was sleepwalking through the twenty years before 2000,” he says. “I knew that there was a right-left division, I had a pretty good sense that people like Dick Armey were not good to have rational discussion with, but I didn’t really have a sense of how deep the divide went.”

Zero rupee note combats Indian bribery

Petty bribery is common in India, but the introduction of a zero rupee banknote has given some would-be bribers pause.

One such story was our earlier case about the old lady and her troubles with the Revenue Department official over a land title. Fed up with requests for bribes and equipped with a zero rupee note, the old lady handed the note to the official. He was stunned. Remarkably, the official stood up from his seat, offered her a chair, offered her tea and gave her the title she had been seeking for the last year and a half to obtain without success.


Products that did well during the recession

They include camping gear, Hyundai cars, and upscale generic products. (via mr)


Predicting Olympic medal counts

Economics professor Daniel Johnson makes accurate Olympic medal predictions using a handful of indicators that are unrelated to sports.

His forecast model predicts a country’s Olympic performance using per-capita income (the economic output per person), the nation’s population, its political structure, its climate and the home-field advantage for hosting the Games or living nearby. “It’s just pure economics,” Johnson says. “I know nothing about the athletes. And even if I did, I didn’t include it.”

For the upcoming 2010 games in Vancouver, Johnson predicts that Canada, the US, Norway, Austria, and Sweden will end up with the most medals. (thx, brandon)

Update: Johnson’s predictions were a bit off.
