Sort of like lunch, there is no such thing as a free parking space. It costs us dollars or time.

Hoping to optimize so valuable a commodity, some cities are installing parking devices that use demand and supply to price spots. The approach resembles a variable pricing model where a good becomes more expensive when less is available.  Others, concerned about the time we waste have apps that instantaneously identify empty parking spaces.

Now, we can add Parking Panda.

Like any market maker, Parking Panda pairs people with parking spots and those who need them. Anyone who has a parking spot can enroll. You might own an office building with a lot that is unused over the weekend or have a home with a driveway you would like to monetize. Whatever the reason, by enrolling with Parking Panda, someone looking for parking can find you.

Our bottom Line:  Isn’t it fascinating how a market, with no direction from government, can satisfy people’s needs and make a community more efficient?

Sources and Resources: Thanks to Slate where I first learned about Parking Panda. Also, here is the classic Donald Shoup paper, ”The High Cost of Free Parking,” an econlife post on San Francisco parking solutions, and a recent NY Times article on their progress.

Decisions Have An Opportunity Cost That Require Tradeoffs

One of the first calls a new Nobel Prize winner might get is from Adam Smith, editor of NobelPrize.org. As you might expect, hearing his name, people initially wonder if the call is for real. Usually Mr. Smith does a quick interview and sometimes, if the winner missed the congratulatory phone call, he shares the good news.

This year, Adam Smith called other 2012 Nobel recipients but not the people who got the econ prize. 89 years old, Lloyd Shapley, professor emeritus, University of California, Los Angeles was not available to talk. His co-prize winner, Alvin E. Roth, a Harvard professor (who will soon be at Stanford), told a bit about himself and his work to a different Nobel caller. (I am disappointed that I cannot say Adam Smith called the new econ laureates.)

In markets that do not involve money, it is tough to create optimal matches. Working separately, these scholars created the math that made it possible. As Dr. Roth explains in his Nobel interview,  he developed a practical application of the concept that Lloyd Shapley and David Gale created. Because of Shapley and Roth, more donors and recipients are paired for kidneys, more people can get assigned the roommates they each want and more NYC children can go to schools that prefer them. You can see the complexities in the diagram below from a Nobel website.

Technically the Nobel Prize in economics is really the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel because it was created long after Alfred Nobel died and therefore was not in his will. Interestingly, with Lloyd Shapley a mathematician, this year again, one of the economics prizes did not go to an economist. In 2002 it want to Daniel Kahneman, a psychologist and in 2009 to Elinor Ostrom, a political scientist.

A final fact: I was delighted that in his interview, Dr, Roth said, “Yes, economics is about real life, so I’m very interested in that.”

Sources and Resources: I suggest listening firsthand to Dr. Roth’s interview so that you can “meet him” and hear firsthand what he does. To learn more about how Dr. Shapley and his associate, David Gale, established the groundwork for Dr. Roth, their brief and easy to understand 1962 math article about “pairwise” matching in marriage markets is fascinating. For the detailed explanation of the three scholars’ accomplishments, Nobel has an excellent description that also has more about the diagram I’ve included. Finally, I suggest looking at Dr. Roth’s blog. He has a great smiling picture of him and his wife with the caption, “An inadvertent ad for Starbucks.”

 

 

 

 

And, here, also from Nobel.org, are pictures of Dr. Roth (above) and Dr. Shapley.

At the Paradise Pigeon auction in Belgium, a Dutch breeder sold a female pigeon to a Chinese shipbuilder for $328,000. Purchased to breed rather than race, Dolce Vita (the bird) will enable Hu Zhen Yu, also the owner of a pigeon racing group, to elevate China in a sport that had been dominated by Germany, Holland, Great Britain and Belgium.

With the capacity to fly more than 60 miles an hour and to cover 500 miles in one day, carrier pigeons are faster than any horse and rider. As a result, sort of like FedEx, they were used to fly stock prices between cities during the mid-19th century before the telegraph replaced them.

Our bottom line? Prices created by markets convey valuable information.

The Economic Lesson

A market is a process that determines the price and quantity of a good or a service. The demand schedule records the different amounts of a commodity, at different prices, that people are willing and able to buy. Correspondingly, the decisions of those who are willing and able to sell different quantities of the item at different prices are the supply side. When they interact, a market results.

The price of Dolce Vita was more than a number. It represented a wealth of facts about the carrier pigeon market. Because a market created the price, it was meaningful.

An Economic Question: Think of a $20 sweater and a $100 sweater. What information does each price convey?

When a San Francisco court said that certain bone marrow donors could be paid, they did not have to focus on medicine. Instead, the 3 judge panel could have discussed the market.

The court said it was all about new technology that made bone marrow donation more similar to giving blood than an organ. While it is legal to pay a blood donor, compensating someone for an organ is a felony.

Instead though, we could say the case was about the size of the market. The judges’ decision, if it is not reversed, has expanded the bone marrow market. Originally, prohibited, now demand and supply will play a role in determining availability and price for bone marrow donations.

The Economic Lesson

The size of markets can differ and change. With prohibition, the size of the market for alcohol diminished. For votes, substitute SAT test takers and kidneys, markets are illegal. In Why Things Should Not Be For Sale, philosopher Debra Satz suggests 4 criteria that “make particular markets noxious” (p. 9).

  • Looking at participants, she cites 1) people who might be so poor or desperate that they are especially vulnerable and also those with little information that she characterizes as 2) having “weak agency.”
  • Looking at a market’s results, she suggests being aware of “extremely harmful outcomes” 3) for individuals and 4) for society.

With economist Russ Roberts, Dr. Satz discusses her perspective while in this Teaching Company lecture (#29), you might enjoy listening to a half hour discussion of issues that relate to organ transplant markets.

An Economic Question: Thinking of Dr. Satz’s criteria and others that emphasize the lives that would be saved if organs could be bought and sold, would you expand the market for human organs?

To estimate the size of the corn crop, the U.S. Department of Agriculture (USDA) hires corn counters. Calculating stalk stats and assessing cob size, they observe 15 foot sections in thousands of fields. Add to that weather predictions, yield trends, and other pertinent data and you get an estimate for how much corn will be harvested. Once you also know about stockpiles (corn in silos and other storage facilities), a picture of the supply side of the market emerges.

What happens then? In corn (futures) markets, prices respond.

According to the WSJ, inaccurate USDA forecasting has led to more corn price volatility. June 30, 2010 for example, when the USDA said stockpiles were smaller than expected, prices spiked and a rancher had to paid an extra $200,000 for his feed. When prices fell, China was observed “swooping in.” 

Do you want to better understand futures markets? This is a clear explanation of how the orange crop affected prices in (Eddie Murphy’s) Trading Places wonderful climax. A more academic discussion is here.

Our bottom line? Discussed in an econlife post, according to Michael Pollan, more than one-quarter of all supermarket items are affected by the price of corn.

The Economic Lesson

The three basic economic systems are tradition, command and the market. Reflected by corn futures, in reality, most economies are mixtures.

An Economic Question: Name several economies you believe have much more of a market than government influence. Then check the Index of Economic Freedom to see if you are correct.
