CREATING A MARKET FOR GRAIN.

Saturday, March 22nd, 2008

CREATING A MARKET FOR GRAIN. This article by Roger Thurow from the July 1, 2003 Wall Street Journal illustrates the difficulties of encouraging economic development. Just five years ago, Ethiopia was confronted with a famine. Ironically, the article attributes much of the shortage of food to an emphasis on increasing food production while dismantling the government role in the agriculture sector. The private sector was inadequate to take on the burdens of inadequate storage and distribution facilities. In the old days, Communist governments which scorned the role of the middlemen who provided services, and valued only physical production, wound up with food rotting in the fields. Just as it is easy to overlook the importance of distribution, it is easy to overlook the active role that American governments have played in the agricultural sector. The new Ethiopian Commodity Exchange has a lot of problems to deal with.

HOW ETHIOPIA IS IMITATING CHICAGO.

HOW ETHIOPIA IS IMITATING CHICAGO. Roger Thurow had an article in the Wall Street Journal for February 27 about the Ethiopia Commodity Exchange, which was scheduled to open in Addis Ababa in March. The new exchange is patterned after the Chicago Board of Trade. Small farmers with a few acres produce 95 % of Ethiopia’s crops. They usually sell to the first merchant that comes along, leading to very low prices at harvest time. The article said that in the early 1800’s, before the Chicago Board of Trade came into existence, most grain was sold shortly after harvest, which resulted in very low prices. It is intended in Ethiopia that there will be a network of new warehouses so that farmers can store grain and trade the warehouse receipt on the Exchange when they find an attractive price. The article speaks of hopes that the Exchange can connect farmer to world grain markets, but I would think it would be a success if the grain is stored and moved to food-short areas in Ethiopia or elsewhere in Africa.

TELLER AND THE JELLY DOUGHNUT.

Thursday, March 20th, 2008

TELLER AND THE JELLY DOUGHNUT. Adam Gopnik takes note in the article that I linked to yesterday that it is a cardinal sin for a magician to reveal to a layman how a trick is done. Nevertheless, I love finding out how a trick is done, and knowing how it is done makes me enjoy it more the next time I see it. I know how to saw a lady in half, but I still enjoy seeing it done. There was a much-hated TV show that revealed how some famous illusions are done. The timing, coordination, mechanical skill, and diversion of the audience’s attention required for each trick was wonderful. I once saw Penn and Teller perform a trick in which Teller was run over by an 18-wheeler in Times Square. Penn demonstrated how the trick would work, using a toy truck and a jelly doughnut which represented Teller. What made the trick for me was the multiple choice they provided, which gave as one of the choices “It’s a fake truck.” This was the correct choice. Penn and Teller showed how they had dummied the air pressure of the tires and filled one side of the body of the truck with concrete blocks so that all the weight of the truck was on the wheels on the other side from Teller. The presentation and the explanation made the trick work for me. Of course, I also enjoy the denouements of detective stories and criticism that explores how poets achieve their effects.

HUNGER ARTISTS AND MAGICIANS.

Wednesday, March 19th, 2008

HUNGER ARTISTS AND MAGICIANS. I wrote here about the popularity of hunger artists in Europe a hundred years ago and about the technical problem they faced in proving they were really fasting. Adam Gopnik had an article (link unavailable) about magicians in the New Yorker for March 17 in which he discusses how the magician David Blaine is testing the limits of what the human body can endure. Blaine’s next performance will be to stay awake for a million seconds (11.57 days). He has already stood on a pole for 35 hours and claims the record for the longest time spent underwater by a mammal (excluding whales). There is still an audience for the equivalent of the hunger artist. What was entertainment in the past is still entertainment today. But what about the problem of showing that it is not all a trick? What does it mean when a professional magician becomes a hunger artist?

SOME COSTS OF MIGRATION.

SOME COSTS OF MIGRATION. Thirty-five years ago we saw BREAD AND CHOCOLATE, a memorable movie about a Sicilian and a Turk trying to find work in Switzerland in order to send money home. Leaving home is hard. There is the difficulty of the new culture and the loss of the old culture. Dilip Ratha’s older sister frets that Ratha now eats with a fork. Ratha says, “On bad days, I do feel lonely in a way that I can’t explain.”

SENDING MONEY HOME.

Tuesday, March 18th, 2008

SENDING MONEY HOME. Jason DeParle has an article in the New York Times for March 17 about an economist who has measured the amount and the importance of remittances that are sent home to poorer countries by migrant workers. Dilip Ratha established that remittances for the Philippines were fifty times greater than had been estimated. For some small countries, remittances are more than twenty per cent of national income. Remittances are three times larger than the total for world foreign aid. They also have advantages over foreign aid–they can’t be skimmed and their use is usually well-monitored by the grantor. Ratha grew up speaking Sambalpuri, a language which “lacks a written script.” A teacher says that students in his village are “astonished that this young man from Sindhekela flies around in planes.” Sindhekela now has three cellphone towers; all the children now have shoes. Ratha attributes this to internal migration–remittances from migrants to India’s cities.

A VOICE FROM 1873.

Monday, March 17th, 2008

A VOICE FROM 1873. An article in yesterday’s New York Times by Edmund L. Andrews is headlined: “Fed Chief Shifts Path, Inventing Policy in Crisis.” and continues in the text that: “Mr. Bernanke [Ben Bernanke, the Chairman of the Federal Reserve Bank] is inventing policy on the fly.” The policy change was in connection with a Fed bailout of Bear Stearns. The novelty in the policy is that the Fed is buying a different kind of security than is its custom: “In a move that would have been unthinkable until recently, the central bank agreed to accept potentially risky mortgage-backed securities as collateral.” Kids, from another point of view, what the Fed is doing — even the acceptance of potentially risky collateral — is in accordance with the traditional role of a central bank. In 1873, Walter Bagehot wrote LOMBARD STREET, which set forth his concept of the role of a central bank (the Bank of England for Bagehot; now in the United States, the Federal Reserve Bank). Bagehot argued that in a credit crisis, the central bank should act as the Lender of Last Resort. Meyer Burstein in MONEY summarized: “Bagehot showed a fine appreciation of what has come to be the accepted doctrine of central bank behavior during a domestic crisis of liquidity: namely to stand ready to purchase broad ranges of securities, damping cumulative speculative forces feeding an internal drain.” Burstein noted that Bagehot wanted the Bank of England to lend on a very broad base of collateral, which is what the Fed has just done.

THE CARTOON EXPLANATION OF SUBPRIME MORTGAGES.

Sunday, March 16th, 2008

THE CARTOON EXPLANATION OF SUBPRIME MORTGAGES. One of the posts by Doctor Manhattan that I linked to yesterday had this cartoon explanation of the subprime mortgage crisis. (The link came from Greg Mankiw, who is a notable economist and teacher). Nick sent me an e mail asking: “Just flipped through the sub-prime mortgages cartoon. I realize it’s crude, but is that really the type of thing that was going on?” Kids, the answer is: YES. I would add two points. First, what is shown in the cartoon happened on an enormous scale, involving billions of dollars. Second, the cartoon depicts a “Norwegian Village Pension Fund” as the hapless purchaser of some of the artificially-created mortgage-based securities (referred to as CMO’s and CDO’s in the cartoon). Norwegian Village Pension Funds are not the only owners of these securities. Nobody knows who owns — or is exposed to the risks of — these securities of doubtful value (take insurance companies as an example). There are huge losses out there. How can you know whether a company you may be doing business with has enough bad securities that it won’t be able to pay you promptly — or at all?. The AP reports today that JPMorgan has agreed to buy Bear Stearns for a price that is 1% (one per cent!) of the price the investment bank was worth 16 days ago. It notes that “Bear Stearns was founded in 1923 and in recent years was best known for its aggressive investing in mortgage-backed securities.”

A SIMPLE WAY TO FOOL CONSUMERS.

Sunday, March 16th, 2008

A SIMPLE WAY TO FOOL CONSUMERS. I posted here on some ways sellers can shift a consumer’s demand curve.Tim Harford in this weekend’s Financial Times suggests the frequent use of random markups. His example is a medium-sized package of washing powder which is priced much higher than the equivalent price for the small or large size. The theory is that price-conscious consumers will notice –and the others won’t.

DOCTOR MANHATTAN AND THE ECONOMICS OF THE FAMILY.

Saturday, March 15th, 2008

DOCTOR MANHATTAN AND THE ECONOMICS OF THE FAMILY. One of my favorite blogs has been Doctor Manhattan. Doctor Manhattan took a vacation from blogging for over two years, but I continued to use his excellent blogroll as a reference (look at the baseball sites, for example). He has now returned. Kids, this post links to an amusing cartoon guide to the subprime mortgage crisis. This post reports on ways that economists are looking at the family. He links to an article by Betsey Stevenson and Justin Wolfers that argues that there has been a shift from a shared-production model to a shared-consumption model of marriage. A family shares production when the husband and wife have different skills so that the family can benefit from specialization (“opposites attract”). In a family that shares consumption (“like attracts like”), the spouses share similar experiences and values.
