Ever get the feeling that the entire global economy is one big experiment conducted by several former Keynesian economists from MIT with a bent for central planning, who sit down in conspiratorial dark rooms in tiny Swiss cities and bet it all on green until they double down so much nobody even pays attention to the game? No? You should. Jon Hilsenrath, of all people, explains why.

From the WSJ:

Every two months, more than a dozen bankers meet here on Sunday evenings to talk and dine on the 18th floor of a cylindrical building looking out on the Rhine.

The dinner discussions on money and economics are more than academic. At the table are the chiefs of the world's biggest central banks, representing countries that annually produce more than $51 trillion of gross domestic product, three-quarters of the world's economic output.

Of late, these secret talks have focused on global economic troubles and the aggressive measures by central banks to manage their national economies. Since 2007, central banks have flooded the world financial system with more than $11 trillion. Faced with weak recoveries and Europe's churning economic problems, the effort has accelerated. The biggest central banks plan to pump billions more into government bonds, mortgages and business loans.

Their monetary strategy isn't found in standard textbooks. The central bankers are, in effect, conducting a high-stakes experiment, drawing in part on academic work by some of the men who studied and taught at the Massachusetts Institute of Technology in the 1970s and 1980s.

"Will history decide they did too little or too much? We don't know because it is still a work in progress," said Kenneth Rogoff, an economics professor at Harvard and co-author of a book, "This Time Is Different," examining financial crises over eight centuries. "They are taking risks because it is an experimental strategy."

Three of the world's most powerful central bankers launched their careers in a building known as "E52," home to the MIT economics department. Fed Chairman Ben Bernanke and ECB President Mario Draghi earned their Ph.D.s there in the late 1970s. Bank of England Governor Mervyn King taught briefly there in the 1980s, sharing an office with Mr. Bernanke.

Many economists emerged from MIT with a belief that government could help to smooth out economic downturns. Central banks play a particularly important role in this view, not only by setting interest rates but also by influencing public expectations through carefully worded statements.

While at MIT, the central bankers dreamed up mathematical models and discussed their ideas in seminar rooms and at cheap food joints in a rundown Boston-area neighborhood on the Charles River.

Over Sunday dinners in Basel, which often stretch to three hours, they now talk of pressing, real-world problems with authority. The meals are part of two-day meetings held six times a year at the BIS. Dinner guests include leaders of the Fed, ECB, Bank of England and Bank of Japan, as well as central bankers from India, China, Mexico, Brazil and a few other countries.
