A Fiscal Stimulus Turkey

From A Brief History of Black Friday:

In 1939, the Retail Dry Goods Association warned Franklin Roosevelt that if the holiday season wouldn't begin until after Americans celebrated Thanksgiving on the traditional final Thursday in November, retail sales would go in the tank. Ever the iconoclast, Roosevelt saw an easy solution to this problem: he moved Thanksgiving up by a week.

Roosevelt didn't make the announcement until late October, and by then most Americans had already made their holiday travel plans. Many rebelled and continued to celebrate Thanksgiving on its "real" date while derisively referring to the impostor holiday as "Franksgiving." State governments didn't know which Thanksgiving to observe, so some of them took both days off. In short, it was a bit of a mess.

Trying to increase spending by moving Thanksgiving up a week?  Dumb.  But really, is this so different than say cash for clunkers?  Hat tip: Boing Boing.

Ariely on Thanksgiving

Ezra Klein asked Dan Ariely for Thanksgiving advice:

"Move to chopsticks!" he exclaimed, making bites smaller and harder to take. If the chopsticks are a bit extreme, smaller plates and utensils might work the same way. Study after study shows that people eat more when they have more in front of them. It's one of our predictable irrationalities: We judge portions by how much is left rather than how full we feel. Smaller portions lead us to eat less, even if we can refill the plate.

Speaking of which, Ariely suggests placing the food "far away." In this case, serve from the kitchen rather than the table. If people have to get up to add another scoop of mashed potatoes, they're less likely to take their fifth serving than if they simply have to reach in front of them.

"Start with a soup course," he says. That is what economists refer to as a default: Rather than putting everything on the table for people to choose, you begin by making the choice for your guests. If the first course is relatively filling and relatively low in calories, everyone will eat less during the rest of the meal.

Indeed, it's not a bad idea to limit the total number of courses. Variety stimulates appetite. As evidence, Ariely brings up a study conducted on mice. A male mouse and a female mouse will soon tire of mating with each other. But put new partners into the cage, and it turns out they weren't tired at all. They were just bored. So, too, with food. "Imagine you only had one dish," he says. "How much could you eat?"

What you eat, of course, is also important. Studies show that people aren't very consistent in the amount of calories they eat each day, but they're very consistent in the volume of food they eat each day. Thanksgiving is an exception to that consistency, but probably not to the underlying rule. Satisfaction doesn't depend on caloric intake; low-calorie, high-fiber foods and foods high in water content are filling. Thus, the more broccoli rabe there is at the table, the better.

Sweet Trade

Here is a fun, easy and effective experiment that instructors can use to illustrate the gains from trade.  The instructor puts chocolate bars ("fun-size") or other candy in bags, one bag for each student. (Alternatively, you can use the type of small items that you can find at a dollar store.  Filling the bags is where the most work comes in especially if you have a large class). Students open the bag and are then asked to write down how much they would be willing to pay for the bag's contents.  But before snacking, students are allowed to trade.  After a few minutes of trade, ask the students to write down their valuation again.  Voila!  Gains from trade.  With a few numbers pulled at random from the students you can do a back of the envelope calculation for the total increase in value.  The experiment doesn't take long and the students will appreciate the candy!

Badges? We don’t need no stinkin badges.

In pursuit of an Eagle Scout badge, Kevin Anderson, 17, has toiled for more than 200 hours hours over several weeks to clear a walking path in an east Allentown park.

Little did the do-gooder know that his altruistic act would put him in the cross hairs of the city's largest municipal union.

Nick Balzano, president of the local Service Employees International Union, told Allentown City Council Tuesday that the union is considering filing a grievance against the city for allowing Anderson to clear a 1,000-foot walking and biking path at Kimmets Lock Park.

"We'll be looking into the Cub Scout or Boy Scout who did the trails," Balzano told the council.

Only in economics are floors above ceilings!

Only in economics are floors above ceilings!  It might be better to say "a minimum allowed price above the market price" and "a maximum allowed price below the market price," although that is a bit of a mouthful.  I find that the floors and ceilings language does work, however, if the instructor explicitly points out the oddity of floors above ceilings!  In that case, students find the distinction memorable.

The Big Questions

In The Big Questions, Steven Landsburg ventures far beyond his usual domain to take on questions in metaphysics, epistemology and ethics.  Beginning with Plato, mathematicians have argued for the reality of mathematical forms.  Rene Thom, for example, once said "mathematicians should have the courage of their most profound convictions and thus affirm that mathematical forms indeed have an existence that is independent of the mind considering them."  Roger Penrose put it more simply, mathematical abstractions are "like Mount Everest," they are, he said, "just there."

All this must make Steven Landsburg history's most courageous mathematician because for Landsburg mathematical abstractions are not like Mount Everest, rather Mount Everest is a mathematical abstraction.  Indeed, for Landsburg, it's math all the way down – math is what exists and what exists is math, A=A. 

Read the book for more on this view, which is as good as any metaphysics that has ever been and a far sight better than most.  Moreover, Landsburg's view is not empty, it does have real implications.  Since there is no uncertainty in math, for example, Landsburg's view supports a hidden variables or multiple-worlds view of quantum physics.

Speaking of quantum physics, The Big Questions, has the clearest explanation of the Heisenberg uncertainty principle that I have ever read.  In fact, this is a necessary consequence of Landsburg's metaphysical views; since it's all math all the way down, the explanation of the uncertainty principle is the explanation of the math and any true uncertainty or mystery is simply a fault of our own misunderstanding.

Turning to epistemology, the theory of beliefs and knowledge, two chapters stand out for me.  I learned a lot from Landsburg remarkable clear explanation of Aumann's agreement theorem–and I say that despite the fact that in the office next to mine is Robin Hanson, one of the world's experts on the theorem (see Robin's papers on disagreement and also his paper with Tyler, but read Landsburg first!).

Landsburg's skills of explanation are also brought to bear in a wonderful little chapter explaining the theory of instrumental variables and of structural econometric modeling  – and this from an avowedly armchair economist!  

Finally for those, like me, who loved The Armchair Economist and More Sex is Safer Sex there is also lots of economics in The Big Questions.  Highly recommended.

Innumeracy can get you killed

"Statistically, it is very dangerous, but I have lived here a long time and I don't feel like I'm in any danger."

That is Justin Fenton, the Baltimore Sun's crime correspondent.

The quote comes from a longer article by a British reporter who switched places with his Baltimore counterpart because he wanted to see whether The Wire was accurate.  It is. 

Caplan on Education

How much does increasing college-going rates matter to our economy and society?

Caplan: College attendance, in my view, is usually a drain on our economy and society. Encouraging talented people to spend many years in wasteful status contests deprives the economy of millions of man-years of output. If this were really an "investment," of course, it might be worth it. But I see little connection between the skills that students acquire in college and the skills they'll need later in life.

NASA FAQ 2012

NASA scientists are frequently being asked questions concerning 2012 and for this reason they have created a web page to answer these questions and reassure the public. e.g.

Q: Is there a planet or brown dwarf called Nibiru or Planet X or Eris that is approaching the Earth and threatening our planet with widespread destruction?

A: Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist. Eris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system; the closest it can come to Earth is about 4 billion miles.

Sigh…. I too fear for our planet.

Unemployment Breakdown

The NYTimes has a nice interactive graphic on unemployment rates and changes over time by demographic characteristic.  I am in the category–white men ages 25-44 with a college degree– with almost the very lowest unemployment rate (3.9%).  Just to compare, as pointed out in the comments, black males 15-24 without a high school degree have an unemployment rate of 48.5%.  Check it out.

Give them your tired, your poor, your huddled masses

Three countries that relied on low-skilled immigrant workers during good times – Japan, Spain, and the Czech Republic – have recently introduced voluntary return programs programs, popularly known as "pay-to-go" programs, in an effort to reduce the number of unemployed immigrants.

The programs established in 2008-2009 generally provide unemployed legal migrants with stipends that cover the cost of a one-way plane ticket "home." Some programs also offer migrants a lump-sum payment.
