Our Daily Bleg: How to Fairly Divide an Estate?

A while back, we ran a bleg in which a reader needed help dividing up a loved one’s furniture and other property. Now a reader named M. writes with a trickier and more philosophical estate-dividing problem:

My grandmother is 93 and in decent health. She has 4 biological children, 10 grandchildren, 23 great-grandchildren and a great-great-grandchild is possible (the oldest great-grandchild is married.) She has a decent amount of assets; barring unforeseen circumstances her estate will be a few million dollars.
From the perspective of fairness, one might say the estate should be divided equally between the four children. From a purely biological perspective, an individual wants to see that his or her genetics be passed on to future generations. In our case, while one of the children produced two grandchildren who in turn have only one of the great-grandchildren, another child produced 5 grandchildren and they in turn 10 of the great-grandchildren.


A Corruption/Parking Tickets Map

Forbes‘s Jon Bruner has made a cool map of economists Raymond Fisman and Edward Miguel‘s paper “Cultures of Corruption: Evidence From Diplomatic Parking Tickets” (noted here earlier). The paper measured diplomats who used their immunity to dodge parking fines, resulting in a list of violations per U.N. diplomat. Kuwait tops the list at 246 violations per diplomat. The map is paired with corruption scores from Transparency International, Bruner notes:

Fisman and Miguel set out to use the parking data to understand the impact of social norms on official corruption. The idea is that diplomatic parking violations are essentially consequence free, except for any approbation that might come from the diplomat’s home state. A political culture that doesn’t mind its diplomats racking up parking tickets might not mind outright corruption.


Bad Karma-geddon? Conjecture, Construction and Congestion in L.A.

L.A.’s “Carmageddon” is over. For those in the rest of the country, or Angelenos who spent the last two months trekking in Bhutan or in monastic seclusion, Carmageddon was the result of the complete closure of a major Los Angeles freeway over the weekend. The results?
Carmageddon was predicted by almost all journalists and government officials to be a brewing traffic nightmare of unprecedented dimensions. Only a day before the event I was reading predictions by our transportation authorities stating that traffic as much as 50 miles away would reach nightmare-like proportions. Only a very few, including myself, predicted we would see a situation of unusually light traffic reminiscent of the last time a similar situation happened: the 1984 Los Angeles Olympics.
In fact, Carmageddon saw stunningly low traffic levels, with many who did venture out reporting they had never driven at such speeds in LA in their lifetimes. Moreover, fears that the project (which involved demolishing half of a bridge over the highway) would drag on into Monday’s rush hour proved totally unfounded, as the work was completed and the freeway reopened on Sunday afternoon, many hours ahead of schedule.


The "Solar Panel" Effect on Home Sales

Our recent podcast on “conspicuous conservation” looked at the “Prius Effect” — that is, how valuable it is for green-leaning consumers to signal their devotion to the environment by driving an obviously-hybrid Toyota Prius. (BTW, you can also fake it with an “instant hybrid conversion kit.”) The episode was based on an interesting paper by Alison and Steve Sexton called “Conspicuous Conservation: The Prius Effect and Willingness to Pay for Environmental Bona Fides.” It included some talk about solar panels as well, and how some people mount them on the street-facing side of their homes even though the sun shines more strongly on the rear.


Income Equality in Revolutionary America

A tad late for Independence Day, but interesting nevertheless: a new paper called “American Incomes Before and After the Revolution,” by Peter H. Lindert and Jeffrey G. Williamson. Couldn’t find an ungated copy; abstract below (emphasis is mine):

Building social tables in the tradition of Gregory King, we quantify the level and inequality of American incomes before and after the Revolutionary War. Our tentative estimates suggest that between 1774 and 1800 American incomes fell in real per capita terms. The colonial South was richer, and then suffered a greater Revolutionary decline, than suggested by previous estimates. Any rapid growth after 1790 seems to have just partially offset part of a very steep wartime decline. We also find that free American colonists had much more equal incomes than did households in England and Wales. Indeed, New England and the Middle Colonies appear to have been more egalitarian than anywhere else in the measurable world. The colonists also had greater purchasing power than their English counterparts over all of the income ranks except in the top few percent.


For Economic Growth, Does Penis Size Matter More Than Political System?

In SuperFreakonomics Illustrated, we published this penis-flag chart in the context of a discussion about how ill-fitting condoms failed to protect men and women alike in countries including India. The fact is that reliable penis-size data is notoriously hard difficult to come by get. Here’s one website that aggregates data from around the world, and here are its data sources.
Using those data, Tatu Westling of the University of Helsinki has written a paper called “Male Organ and Economic Growth: Does Size Matter”? Please do take this with a sizable grain of salt.

Who Should Play Stephen Dubner in Turbulent Souls Film?

Stephen Dubner’s first book, Turbulent Souls, has been optioned by The Group Entertainment (Variety‘s report here), with writer Larry Gross (48 Hours, True Crime, We Don’t Live Here Anymore) to adapt the memoir for the big screen. Not that we have a say in this, but just for fun we’d like to find out which actor Freakonomics readers think should play the Dubner in the film.


A Picture's Worth a Thousand Words

I’m back to inviting readers to submit quotations whose origins they want me to try to trace, using my book, The Yale Book of Quotations, and my more recent researches.
Ed Catlett asked:

“People often say ‘A picture is worth a thousand words.’ I believe the original quote was actually ‘A picture is worth ten thousand words’ as stated by Fred R. Barnard, of Printers’ Ink, 10 March 1927. Which is correct?”


Not the Kind of Customer Review You Read Every Day

You never know what you’ll run across while reading Yelp. While sussing out Philadelphia hotels, I came across this review:

First of all, let me just say that, if you can get a room, this is an excellent hotel. Don’t let the fact that a transgendered prostitute was arrested for killing an occupant here and tried setting fire to his room in November 2010. As with any hotel, you should be careful who you let into your room anyway.

The reviewer gave the hotel four stars out of five. It wasn’t the murder (which, though I was skeptical, was for real) that led him to deduct a star, but rather the low water pressure and bad hours at the fitness center.
And you wonder why companies are still nervous about the whole customer-review concept?


Prediction Markets on the Debt Ceiling, U.S. Credit Downgrade

Over at Intrade, there are two “hot” markets involving the odds that Congress will raise the U.S. debt ceiling.
– Congress to approve increase in U.S. debt ceiling before midnight on July 31, 2011: 40% (It was 65% a month ago)
– Congress to approve increase in U.S. debt ceiling before midnight Aug. 31, 2011: 75% (It was 85% a month ago)
And at Irish bookmaker PaddyPower.com, here is the line on a Moody’s downgrade:
Will Moody’s downgrade the U.S.?
-Yes: 9/2
-No: 1/8


Another Salvo in the Tenure Debate

Should professors have tenure? The question, debated recently on this blog, misses the mark—as do the usual answers, whether “yes,” “no,” or “maybe.”
On the “no” side, it is argued that tenure protects incompetent spongers. A very reliable (tenured) colleague, at a university that shall remain nameless, tells me of professors whose interests are no longer intellectual and who spend their time playing the real estate market. Their research productivity, measured in grant dollars or papers, is low; thus, the university is angry. Their teaching is also substandard, yet not quite abysmal enough to get them fired. To urge them to resign, the department punishes them… by assigning extra teaching!
On the “yes” side, it is argued that tenure protects academic freedom. That point is made by my colleague on this blog Dan Hamermesh. Ten years ago I agreed with him. I would not have imagined my future self happy as an associate professor at Olin College of Engineering: Olin offers six-year renewable contracts instead of tenure. Now I see Olin’s system as a reasonable alternative to tenure, for I no longer believe that tenure supports academic freedom.


The Texas Tax Holiday: A Business Subsidy Even a Kid Can See Through

The 13-year-old grandson and his 11-year-old sister are discussing the Texas tax holiday—for one weekend in August there will be no sales tax on school-related items. The grandson says stores will cut prices to compete for customers. The granddaughter, already an inveterate shopper, says no: With the tax holiday there will be so many customers that the stores will be able raise prices.
While prices won’t rise compared to the previous weekend, the granddaughter seems to understand that an inelastic demand means the incidence of (gain from) the tax cut will be on the sellers—the customers are unlikely to get much of a bargain. A subtle, Texas-style subsidy to business; but one that even an 11-year-old can see through!


Debt Ceiling Poll: To Raise or Not to Raise

According to a new poll from the Pew Research Center and the Washington Post, more people see raising the debt limit as a bigger risk than not raising it. Though it’s close, and the margin has shrunk over the last two months, 47% say they’re more concerned about the risks that raising the debt limit pose to the U.S. economy than they are over the fallout of failing to do so; 42% see it the other way around.
Sounds like a good time for a Freakonomics Poll:


A Twitter Experiment

I’m a long-time Twitter skeptic. It’s difficult for an economist to see a 140 char lmt as a ftr. My journalist friends tell me I’m dead wrong. And a recent long and boozy evening with co-founders Evan Williams and Jason Goldman convinced me to give it a try. Is Twitter worth the hype? Let’s find out.
Today I’m beginning my Twitter Experiment. I’m now tweeting @justinwolfers. I’m going to keep this up for a couple of weeks as a “burn in” period—basically so that I can learn the ecosystem before my experiment begins. Then on the morning of August 1, I’m going to wake up, and flip a coin. Heads, I’ll open Twitter; tails I won’t. And I’ll do the same on August 2, and then every day for three months. If the coin comes up heads, it doesn’t necessarily mean that I’ll tweet, just that it will be a Twitter-aware day; I’ll consume the stream, and tweet away if I feel the need. Tails, and I’ll simply tweet “Tails, goodbye,” close the stream (unless I need it for research) and then resist the urge to tweet for the rest of the day.


Dollar Coins for Airline Miles? Bon Voyage!

A few weeks ago, we wrote about the Fed’s $1 billion stash of unwanted coins, and the Federal government’s seemingly failed experiment to get us to trade in our dollar bills for dollar coins. The folks over at NPR’s Planet Money got inside access to see the pile of coins, which so far has cost $300 million to manufacture. Despite the clear failure to create demand, the program, authorized by Congress in 2005, won’t end until 2016.
Now it seems some folks have found an easy way to profit from all those unwanted coins. Planet Money reports that people have started buying the coins with their credit cards, thereby earning lots of airline reward miles. The coins are sent to them by the government for free. The buyers then deposit the coins in their bank accounts, pay off their credit card bill… et voila, a free plane ticket to Paris. While the U.S. Mint is a bit miffed by the scheme, a spokesman admits that there’s nothing illegal about it.


More Evidence of Blue Monday Effect?

A new study by two economists from the University of British Columbia, John F. Helliwell and Shun Wang, shows that Americans are happier on weekends. This is more true for men than for women, as well as for married couples.
Abstract here:

This paper exploits the richness and large sample size of the Gallup/Healthways US daily poll to illustrate significant differences in the dynamics of two key measures of subjective well-being: emotions and life evaluations. We find that there is no day-of-week effect for life evaluations, represented here by the Cantril Ladder, but significantly more happiness, enjoyment, and laughter, and significantly less worry, sadness, and anger on weekends (including public holidays) than on weekdays. We then find strong evidence of the importance of the social context, both at work and at home, in explaining the size and likely determinants of the weekend effects for emotions. Weekend effects are twice as large for full-time paid workers as for the rest of the population, and are much smaller for those whose work supervisor is considered a partner rather than a boss and who report trustable and open work environments. A large portion of the weekend effects is explained by differences in the amount of time spent with friends or family between weekends and weekdays (7.1 vs. 5.4 hours). The extra daily social time of 1.7 hours in weekends raises average happiness by about 2%.


QE3? Not So Fast. Let's Debate the Merits of QE2 First

The Fed’s second round of monetary stimulus, the $600 billion QE2, ended on June 30. Since then, financial markets have rallied on news of another Greek bailout, and then fallen on weakening jobs and economic news from the U.S. The Dow is basically back to where it was when QE2 ended on June 30. So the world hasn’t ended, and yet there are those who think we need a third round. The minutes of the latest meeting of Federal Reserve officials, released Tuesday, show them divided on whether to implement a third round of monetary stimulus. Before we get ahead of ourselves, let’s first assess QE2. For that, we turn to two of our regular contributors, Justin Wolfers, and James Altucher.


What Would a Millennial-Generation Budget Look Like?

The average age of Congress is 57.4 years-old. With all the talk (from both sides of the aisle) about how our ballooning debt is stealing from today’s young people, shouldn’t they have a voice in deciding how to solve our long-term fiscal problems, considering they’ll be the ones paying for them? And yet, now that Rep. Aaron Schock (R-IL) has turned 30, not a single member of Congress is in his/her twenties.
What would a budget designed by the Millennial Generation look like? We now know thanks to a group of 18- to-26-year-olds who have released a budget proposal reflecting their priorities. It’s even been scored by the CBO. Organized by the Roosevelt Institute’s Campus Network, the group, along with a handful of think tanks, was given a $200,000 grant by the Peter G. Peterson Foundation to craft a budget proposal.


Australia's Rising Political Star Is an Award-Winning Economist

My good friend Andrew Leigh is the winner of the Young Economist Award, granted every two years to the best Australian-based economist under the age of forty. It’s really a rather splendid achievement. And entirely well-deserved.
Andrew’s career has been quite extraordinary. You see, economics was neither his first career, nor is it his current career. He began life as a star lawyer—clerking for the Aussie equivalent of the Supreme Court, and joining one of the big city firms. He then moved on to his second act as a policy advisor for the center-left politicians in both Australia and the UK, and a think tank in the U.S.
Finally, he began his third act, as an academic economist.


A Solution to Car Accident Rubbernecking: Setting Screens

A few posts ago I wrote a piece about traffic incidents —some of them quite bizarre—that can cause road congestion. Many of these are due to reasonable or at least understandable causes; for example, we need to have road construction, although here in L.A. we wish we didn’t (more about our “Carmageddon” when the results come in.)
But perhaps the most galling and unnecessary source of incident-related congestion is “rubbernecking.” As we all know, terrific jams can be caused even when the wreck(s) is moved out of the traffic lanes, as passing drivers gape at the carnage. It’s been quite a long time since we shared a common ancestor with the vulture, but evidently an evolutionary tie is still there.
Rubbernecking is one of the more interesting cases of moral whipsawing I can think of. All the time we sit in the jam we curse the drivers in front of us for their blood lust. But when it’s our turn at the front of the line… well, just a quick peek.


Is It Time to End the "War on Salt"?

The assault on dietary salt has been growing, and salt sales have been trending slightly downward. Is this a good fight?
According to Scientific American, perhaps not:

This week a meta-analysis of seven studies involving a total of 6,250 subjects in the American Journal of Hypertension found no strong evidence that cutting salt intake reduces the risk for heart attacks, strokes or death in people with normal or high blood pressure. In May European researchers publishing in the Journal of the American Medical Association reported that the less sodium that study subjects excreted in their urine—an excellent measure of prior consumption—the greater their risk was of dying from heart disease. These findings call into question the common wisdom that excess salt is bad for you, but the evidence linking salt to heart disease has always been tenuous.

Did Yankees Fan Really Get Hosed in Deal for Jeter Homerun Ball?

A lot of people are saying that Christian Lopez, the guy who caught Derek Jeter‘s 3,000-hit homerun ball, got hosed by the Yankees when he gave it back in return for some signed memorabilia and Yankees tickets worth an estimated $70,000. According to a Bloomberg article, the ball’s estimated value could be as high as $250,000. So the knee-jerk reaction of a lot of headlines was to assume that Lopez left $180,000 on the table, even though last month, Bloomberg reported a much more conservative estimate of between $75,000 and $100,000 for Jeter’s 3,000-hit ball. I’m not saying it couldn’t go for $250,000, but assuming it’s a given seems presumptive.


How "Patent Trolling" Taxes Innovation

Applying for a patent is expensive. Fees can exceed $25,000, and most applications require at least a couple years of effort. We might expect that anyone considering applying for a patent would be fairly certain of the merits of their case for one. And yet, of the patents granted by the U.S. Patent and Trademark Office (PTO) that are subsequently litigated, 40% are declared invalid in court.
A court’s declaration that a patent is “invalid” means it should never have been granted in the first place, usually because the invention has been done before, or because it’s obvious to anyone familiar with the patent’s particular scientific or technical field. So why do so many people spend so much time and money filing for patents that are ultimately declared invalid?


L.A.'s Carmageddon: Would Building a Train Be Smarter Than Widening the 405?

The “mother of all traffic jams,” in the words of L.A. County supervisor Zev Yaroslavsky, is coming to Los Angeles. On the weekend of July 16/17, an 11-mile segment of Interstate 405 will be closed as part of a $1 billion widening project. Reading of the expected traffic jams, and having recently returned from western Europe, where I traveled mostly by train, I was reminded of an earlier traffic nightmare.
This example I learned from Robert Caro’s 1974 masterpiece The Power Broker: Robert Moses and the Fall of New York. Robert Moses was New York City’s “master builder” in the mid-20th century, and famously hated public transportation.


Are the Benefits of Prescription Drugs Large Enough to Excuse Overdose Deaths?

That is the question I found myself asking while looking at a new Centers for Disease Control report that analyzes drug-overdose deaths in Florida from 2003-2009. I am guessing the answer is a resounding yes, but it’s probably a question worth asking. During that period, the death rate for prescription drugs rose 84.2 percent, from 7.3 to 13.4 per 100,000 people. (Note that these numbers represent unintentional deaths, not suicides — although when you’re talking about death by drugs, the intention isn’t always clear.) Interestingly, the death rate from illicit drugs — primarily heroin and cocaine — has fallen 21.4 percent, to 3.4 per 100,000 people.


A Debate on University Tenure

With only 8 percent of private employees belonging to trade unions, job security outside government employment has become a sometime thing. One group of employees, however, does have nearly total job security: tenured university professors. Faculty tenure is under attack as never before in the past 50 years.
I like tenure, but why should my group of workers get special protections against the vicissitudes of demand for our “product?” Self-interested arguments about job protection are unsatisfactory. I recently “debated” a journalist on this issue, with the resulting short video from the Texas Tribune:
