12 Μύθοι για την Αγορά

του Αριστείδη Χατζή

Παραπολιτική
24 Δεκεμβρίου 2011

Στο δημόσιο διάλογο ακούει και διαβάζει κανείς πολλές ανοησίες. Μερικές από τις χειρότερες όμως αφορούν τις διαβόητες «Αγορές». Στο συλλογικό φαντασιακό έχουν αναλάβει τον ρόλο του μπαμπούλα που τρομοκρατεί τους πολίτες, τις κυβερνήσεις ακόμα και τους διεθνείς οργανισμούς. Η εικόνα που κυριαρχεί είναι ότι οι Αγορές είναι σαν τα Τρολς, τα μυθικά τέρατα της σκανδιναβικής μυθολογίας: πανίσχυρες, ανορθολογικές, ασύδοτες, κινούνται ανεξέλεγκτα και απρόβλεπτα με ένα μόνο σκοπό, να καταστρέψουν τα πάντα στο πέρασμά τους. Για τους λίγο πιο εύπιστους είναι απαραίτητο και ένα ανθρωπομορφικό στοιχείο - πίσω από τις Αγορές υπάρχουν συγκεκριμένοι άνθρωποι και οργανώσεις που κινούν τα νήματα: η λέσχη Bilderberg, η Τριμερής, οι τραπεζίτες, οι Εβραίοι, οι Αμερικάνοι - τώρα και οι Γερμανοί.

Πάντα οι άνθρωποι προσπαθούσαν να εξηγήσουν φαινόμενα που αδυνατούσαν να κατανοήσουν καταφεύγοντας στη μεταφυσική. Η πολυπλοκότητα ενός κοινωνικού φαινομένου όπως η Αγορά, η άγνοια βασικών οικονομικών εννοιών, η δυσκολία αποδοχής του τυχαίου και η ευκολία αποδοχής απλοϊκών μύθων, η τάση για συνωμοσιολογία και, γιατί να το κρύψουμε άλλωστε, η ευήθεια, οδηγούν αναπόφευκτα σε μεταφυσικού τύπου κατασκευές με κυρίαρχο το ανθρωπομορφικό στοιχείο. Όσο δύσκολο είναι να κατανοήσει ο απλός άνθρωπος το μηχανισμό της Εξέλιξης άλλο τόσο είναι δύσκολο να κατανοήσει τους μηχανισμούς της Αγοράς.

Στο υπόλοιπο αυτού του κειμένου θα προσπαθήσουμε να καταρρίψουμε εν συντομία 12 μύθους για την Αγορά και να απαξιώσουμε τις αντίστοιχες λανθασμένες κυρίαρχες αντιλήψεις.

Μύθος 1: Η Αγορά είναι ένα μυθικό τέρας που μπορεί και να σας φάει ζωντανούς.

Ναι, μη σας φαίνεται υπερβολικό. Για πολλούς ανθρώπους η Αγορά είναι ένα από τα πολλά τέρατα που δεν τους αφήνουν να κοιμηθούν. Φαντάζομαι ότι αν ποτέ κατανοήσουν τι πραγματικά είναι η Αγορά, θα σοκαριστούν: η Αγορά είμαστε εμείς. Εσείς, εγώ, οι φίλοι σας, οι γονείς σας, τα αδέλφια σας, οι συνάδελφοί σας, το αφεντικό σας, ακόμα και οι εχθροί σας. Άτομα, νοικοκυριά, επιχειρήσεις μικρές, μεσαίες και μεγάλες. Οι τράπεζες, οι πολυεθνικές επιχειρήσεις, ο Bill Gates, ο George Soros, ο Νίκος Αλέφαντος, ο Αρχιεπίσκοπος Ιερώνυμος, η Έλενα Παπαρίζου, η κομμώτριά σας, ο μανάβης σας αλλά και ο μπατζανάκης σας. Oι αγορές και οι πωλήσεις, η παραγωγή προϊόντων, η παροχή υπηρεσιών, η κατανάλωση, η ζήτηση και η προσφορά, οι επιθυμίες και οι προτιμήσεις, οι προσδοκίες μας, το ρίσκο, η αβεβαιότητα, οι ζημιές, τα κέρδη, οι ευκαιρίες, οι ιδέες, τα λάθη. Όλες οι αποφάσεις μας, όλες μας οι συνήθειες, το σύνολο σχεδόν της δραστηριότητάς μας αποτελεί μέρος αυτής της Αγοράς.

The Darwin economy

Robert H. Frank interviewed by Romesh Vaitilingam

Vox
December 23, 2011

Robert Frank of Cornell University talks to Romesh Vaitilingam about his book, "The Darwin Economy: Liberty, Competition and the Common Good." He argues that Charles Darwin's understanding of competition – in which individual and group interests often diverge sharply – describes economic reality far more accurately than Adam Smith's. They discuss the implications of this view for current debates about inequality, taxation, and policies to get out of economic stagnation. The interview was recorded in London in November 2011.

Artistic labour and occupational choice in Baroque painting

by Federico Etro

Vox

December 23, 2011

To some, the world of art and world of economics are diametrically opposed. To others, such as the author of this column, they are part of the same. This column looks at the wages of painters during the 17th century Baroque art movement and asks what insights it can provide for art lovers, economists, and those who consider themselves both.

Economists are always on the lookout for new data to test their theories. But rather than sit around itching for the latest surveys or commissioning new randomised trials, researchers might want to dig up what we already have. With a bit of luck, the pages of history can be a rewarding friend. Take for instance the well-documented details of painters in 17th century Italy, at the height of the Baroque age. This is an example of a high-skilled labour market and can provide a fruitful area for study.

One of the most impressive and rapid features of the Baroque art movement was the innovation that led mass productions of new genres of painting – to the economists among us, this is a form of horizontal product differentiation.

Beyond old genres such as figurative paintings (including religious, mythological, and historical subjects) and portraits, the new genres of the Baroque art market included still lifes (reproducing animals, fruits, flowers, and lifeless objects), landscapes (reproducing the countryside or the urban environment), so-called genre paintings (reproducing daily life scenes, as in Exhibit 1 by Caravaggio) and battles (reproducing fights without necessarily a specific historical content). Each genre represented a specific sector of production, and painters either specialised in one or few genres or they could switch between them according to the market opportunities driven by price differentials (think of Caravaggio, who introduced still lifes and genre paintings and yet was often engaged in figurative paintings and portraits).

United States Ranks 20th in Holiday Spending

National Science Foundation
Press Release 11-269
December 22, 2011


Americans typically spend $70 billion more in December than in the average of November and January (the months around December). In a recent National Science Foundation-sponsored interview, Joel Waldfogel, the Carlson School's Frederick R. Kappel Professor of Applied Economics at the University of Minnesota uses that increase to measure the amount of holiday gift-giving. This level of spending is lower than in other countries. "We're about the 20th largest in terms of countries in the world," said Waldfogel, referencing how much U.S. December spending increases.

Waldfogel is the author of Scroogenomics: Why You Shouldn't Buy Presents for the Holidays. He notes that even though the U.S. economy has grown since the turn of the last century, the amount of U.S. spending in December (relative to November and January) has not kept pace with that growth. The extra spending in December is less as a percentage of Gross Domestic Product than it has been at any time over the last 75 years.

He makes an additional point that the impact of this spending is even smaller if measured by the satisfaction it produces. The reason, he said, is simple: "The problem with gift giving is that somebody is going out and spending $100 on someone else and if the giver does not know exactly what the recipient wants, it is possible for the giver to spend $100 and buy something the recipient would only be willing to pay $50 or perhaps nothing for."

This type of gift giving, said Waldfogel, undermines economically efficient choices. "Whatever amount of spending occurs, it results in less satisfaction than could have occurred if people bought stuff for themselves," which, he claims, results in the loss of billions of dollars in economic value to the overall economy.

Reframing the Debate Over Using Phones Behind the Wheel

New York Times
December 17, 2011

For years, policy makers trying to curb distracted driving have compared the problem to drunken driving. The analogy seemed fitting, with drivers weaving down roads and rationalizing behavior that they knew could be deadly.

But on Tuesday, in an emotional call for states to ban all phone use by drivers, the head of a federal agency introduced a new comparison: distracted driving is like smoking.

The shift in language, in comments by Deborah Hersman, the chairwoman of the National Transportation Safety Board, opened a new front in a continuing national conversation about a deadly habit that safety advocates are trying desperately, and with a growing sense of futility, to stop.

Her new tack also echoes a growing consensus among scientists that using phones and computers can be compulsive, both emotionally and physically, which helps explain why drivers may have trouble turning off their devices even if they want to. In effect, they are saying that the running joke about BlackBerrys as “CrackBerrys” is more serious than people think.

“Addiction to these devices is a very good way to think about it,” Ms. Hersman said in an interview. “It’s not unlike smoking. We have to get to a place where it’s not in vogue anymore, where people recognize it’s harmful and there’s a risk and it’s not worth it.”

She added: “If you can’t control your impulses, you need to lock your phone in the trunk.”

Jailbreak Rat: Selfless Rodents Spring Their Pals and Share Their Sweets

Scientific American
December 8, 2011

The English language is not especially kind to rats. We say we "smell a rat" when something doesn't feel right, refer to stressful competition as the "rat race," and scorn traitors who "rat on" friends. But rats don't deserve their bad rap. According to a new study in the December 9 issue of Science, rats are surprisingly selfless, consistently breaking friends out of cages—even if freeing their buddies means having to share coveted chocolate. It seems that empathy and self-sacrifice have a greater evolutionary legacy than anyone expected.

In 2007 neuroscientist Peggy Mason of the University of Chicago wrote about the neurobiology of empathy for Scientific American. Inbal Ben-Ami Bartal, a new PhD student in integrative neuroscience who worked across the street from Mason in a different lab, saw the article and proposed a collaboration. "Scientific American really brought us together," Mason says.

In the new study, Mason, Bartal and University of Chicago colleague Jean Decety placed pairs of rats in Plexiglass pens. One rat was trapped in a cage in the middle of the pen, whereas the other rat was free to run around. Most free rats circled their imprisoned peer, gnawing at the cage and sticking their paws, noses and whiskers through any openings. After a week of trial and error, 23 of the 30 rats in the experiment learned to open the cage and free their peers by head-butting the cage door or leaning their full weight against the door until it tipped over. (The door could only be opened from the outside.) At first the rats were startled by the noise of the toppling door. Eventually, however, they stopped showing surprise, which suggests that they fully intended to push the door aside. Further, the rodents showed no interest in opening empty cages or in those containing toy rats, indicating that a break out was their genuine goal.

In this first set of experiments, most rats seemed quite willing to help their peers, but Mason wanted to give them a tougher test. She placed rats in a Plexiglass pen with two cages: in one was another rat, in the other was a pile of five milk chocolate chips—a favorite snack of these particular rodents. The unrestricted rats could easily have eaten the chocolate themselves before freeing their peers or been so distracted by the sweets that they would neglect their imprisoned friends. Instead, most of the rats opened both cages and shared in the chocolate chip feast.
